Structural Studies and Chemical Analysis of FNC
X-ray diffraction (XRD) technology is one of the main tools used to analyze the crystalline structure of fluorinated carbon material (FNC), where specialized energy X-ray sources were used to examine changes in the crystalline structure resulting from material treatment. The XRD pattern of ANC shows broad peaks at angles of 24° and 44°, indicating the presence of an unordered carbon structure, while the FNC material shows a reflection at 13° that indicates the presence of a highly fluorinated graphitic structure. Such changes indicate an increased depth of fluorination, which is associated with the expansion of the distances between crystalline layers due to fluorination. Infrared spectroscopy (FTIR) also contributed to identifying the chemical bonds specific to FNC, as peaks in the spectrum showed the presence of various bonds such as C–F covalent bonds and the CF2/CF3 group. Through these analyses, researchers can understand how chemical treatment affects the physical and chemical properties of materials.
Electrochemical Performance and Battery Characteristics
The performance testing of FNC as a cathode in battery cells was conducted through a continuous discharge process. The electrode preparation involves mixing FNC with specific amounts of other materials such as cellulose and carbon material to improve electrical performance. After forming the mixture, it was spread onto aluminum foil and dried under specific conditions to ensure moisture and residual materials were minimized. The use of lithium as an anode material in coin cells (CR2016) supports the enhancement of electrical performance. Measurements taken in these experiments indicate that FNC exhibits outstanding electrical properties when used as a cathode, enhancing its potential for use in energy storage applications.
Morphological and Structural Properties of ANC and FNC
The morphological properties of ANC clearly reflect the unique formation of carbon nanostructures that range in size from 2 to 5 micrometers, with a honeycomb-like structure providing extraordinary benefits in terms of physical and chemical properties. Under the influence of fluorination, the morphological structure of ANC particles is maintained, enhancing efficiency in the internal transport of lithium ions.

These aspects represent the strengths of the studied carbon materials and contribute to their ability to operate effectively in lithium battery applications.
Analysis
Performance and Electrical Conductivity of FNC
The capacity of the battery and electrical conductivity are fundamental factors in determining the effectiveness of the materials used. A series of repeatable tests were conducted to determine how the concentration of FNC and thermal processes affect battery performance. With each increase in temperature during the fluorination process, it was observed that the surface area of FNC decreased, indicating different types of chemical reactions that enhance aqueous reactions. The results indicate that as the fluorination of the material increases, the potential storage capacity also increases, allowing for more efficient applications in the field of energy storage. These studies highlight the role of material performance in achieving battery effectiveness, encouraging the development of new materials that help in transmitting energy more efficiently.
Properties of Superfluorinated Carbon and Its Electrochemical Activities
Fluorinated composition materials are essential elements in battery manufacturing, especially in lithium metal batteries. Superfluorinated carbon (FNC) has a unique structure characterized by carbon atoms arranged in an sp3 configuration that forms strong bonds with fluorine. As the fluorine-to-carbon (F/C) ratio in the composition increases, the number of carbon-fluorine bonds increases, affecting the electrochemical properties of the materials. According to analysis using XPS, it was observed that increasing the F/C ratio leads to a reduction in the presence of concomitant components, which helps enhance the electrochemical performance properties.
Through the results of the voltage experiments, different discharge characteristics were presented using various discharge rates. For example, the discharge failure of FNC at 0.01C showed excellent specific capacities compared to other materials. This excellent performance is attributed to the gathered spherical structural composition that provides better diffusion pathways for the battery, resulting in a unique capacity for endurance and high energy output. Graphical analyses also show other rates such as energy output and energy density having a positive correlation with the performance of the different tested samples.
Furthermore, CFx compositions significantly impact these properties; more active bonds can enhance discharge efficiency, but the fluorinated bonds work inversely in this regard, increasing electrical resistance and ultimately lowering voltage. This delicate balance between fluorinated bonds and carbon composition is what makes FNC unique in electrochemical applications.
Electrochemical Performance Analysis of the Battery
When FNC was assembled as a cathode for a lithium metal battery, the results were impressive. Electrochemical performance was tested by monitoring discharge voltage curves. Specific capacities were recorded for FNC-0.80, FNC-1.00, and FNC-1.05, and although FNC-1.05 showed the highest specific capacity, FNC-1.00 exhibited better efficiency at high discharge rates, alongside a supporting dataset that corroborates these results.
The discharge curves of different sizes of FNC were compared, showing significant capacity to drop while maintaining high energy even at 20C. FNC not only demonstrates considerable performance efficiency but also showed consistent results with multiple tests over a period, revealing impressive stability in performance.
While optimizing electrochemical performance requires specific attention to fluorine content, as evident from previous studies where high CFx content groups show performance challenges such as voltage delays during discharge. FNC, on the other hand, features less voltage delay during discharge phases, making it a promising candidate for high-performance battery applications.
Chemical Interaction and Ionic Transport Efficiency
The challenge in any battery system is to enhance ionic transport efficiency. In-depth analyses were conducted using the GITT technique (which measures the difference in charge/discharge current) to determine the diffusivity coefficient for Li+ ions in FNC. These measurements confirmed that FNC possesses excellent ionic transport capability compared to other materials.
Measurements were taken to illustrate…
Design of specific equations to determine the diffusion coefficient, which shows high performance during all discharge stages. Initially, DLi+ values increased due to carbon formation during the discharge process, which accelerated ionic transport. As the voltage degraded, the ion transport capacity began to shrink, which is a common phenomenon that ordinary materials suffer from.
Microscopic examinations ensured that FNC maintains a wonder of chemical activity, with a greater number of active C-F bonds, facilitating the ionic process and reducing the negative impact of high fluorine content. In comparison, other CFx failed to overcome the same challenges under the same shade of conditions, elevating FNC’s position as a good option for high-speed applications in batteries.
Study of the effect of fluorine to carbon ratio on electrochemical performance
The fluorine to carbon ratio is a critical factor in determining the properties and performance of the battery. Research shows that a high F/C ratio in FNC has a significant effect on performance efficiency. Although a higher fluorine ratio means more fluorinated bonds, which may be inactive, most discharge processes depend on the presence of effective bonds for ion transport.
Measurements at various discharge rates show that fluorine atoms play a dual role; while they support bond density, excessive fluorine concentration can lead to more tension and slowdown. This is also highlighted during moments of low performance at high discharge rates. Specifically, the greater the number of inactive bonds during discharge, the higher the resistance and delays in voltage appear.
By delving into the details of tests conducted on different samples, it is evident that the effect of the F/C ratio on voltage during the discharge process is clearly related to the overall performance of the battery. FNC-1.00, which contains an optimal ratio, represents the best balance between active and inactive aspects, leading to an increase in energy and high energy output during discharge.
Conclusions and forecasts for the future of FNC in battery applications
Based on the previous analyses, it is clear that hyperfluorinated carbon represents an important starting point in the development of lithium-metal batteries. By understanding the dynamics of its electrochemical interactions, performance can be improved in the future. The results derived from examinations and experiments reflect the deep complexity of interactions within the material.
There is significant potential for further improvements either through materials engineering or compositional changes. Enhancing the overall composition of materials can lead to the development of batteries capable of meeting high market demand, especially in applications for renewable energy storage and electric vehicles.

Additionally, examining performance capacity and a deep analysis of available capabilities can contribute to the continuous improvement and infrastructure of hyperfluorinated batteries, leading the forefront of this emerging industry.
Differences in discharge voltage between battery types
Research shows that the discharge voltage of cathode materials FNC (also known as produced fluorinated carbon) decreases significantly by about 250 millivolts in SPB batteries compared to LPB batteries. This difference primarily relies on the discrepancies in standard electrode potential between lithium ions (Li+/Li, -3.02 volts vs. SHE) and sodium (Na+/Na, -2.71 volts vs. SHE). This voltage difference arises from the physical and chemical properties of the metals, highlighting the importance of choosing the right ions in battery design. SPBs also show lower speed capability compared to LPBs, which is attributed to the size of the ions. For example, the sodium ion Na+ has a larger ionic radius (1.02 angstroms) compared to the lithium ion Li+ (0.76 angstroms), resulting in greater difficulty in transporting Na+. Conversely, FNC still maintains a high discharge voltage and shows remarkable electrical performance despite these limitations, opening the horizons for its use in future applications.
PerformanceElectrical properties of cathode materials FNC in primary batteries
Thanks to their astonishing reflective properties, FNC is an excellent cathode material in primary PPBs. The high number of C–F double bonds enhances the electrical storage capability, leading to improved energy density. At a rate of 20C, FNC can maintain sufficient stability for the discharge rate, recording energy density levels of up to 738 watt-hours per kilogram and a power density of 22,363 watts per kilogram. This results in FNC’s ability to maintain a discharge voltage exceeding 1.5 volts, a remarkable achievement attributed to the good conductivity of the materials that mitigate ohmic polarization effects.
Development of electrical structural properties and microscopic examination results
The effective study of changes in the structural properties of electrodes is also crucial for understanding how batteries perform after discharge. Images captured using SEM before and after discharging the FNC-1.0 cathode at a rate of 0.01C show clear formations of small particles covering the surface of the modified FNC. Previous studies indicate that these morphological properties result from the formation of small LiF crystals during the discharge process. In SPBs and PPBs, the appearance of NaF and KF on the FNC surface after discharge is attributed to similar properties.
Use of FNC in rechargeable primary batteries and future potentials
A chemical method for manufacturing FNC has been proposed that retains reliable properties and serves as excellent cathode materials. FNC shows a high discharge voltage of up to 3.13 volts, demonstrating its potential for use in a wide range of applications. Based on usage experience, the storage capacity of FNC can reach 578 amp-hours per gram, with a capacity retention rate of 75.6% at an increase of 20C. The perfect balance between density and energy, along with low polarization, makes FNC an interesting alternative to commercial fluorinated granite in the potential CFx market.
Conclusion and notes for further research
The results obtained highlight the significance of FNC as cathode materials in rechargeable primary batteries.

Primary Research Using CFx
Research has not only focused on CFx lithium batteries but has expanded to include applications in other systems such as sodium and potassium batteries. The electrochemical characteristics of the CFx compound in these batteries are expected to yield results similar to those recorded in Li/CFx batteries. For instance, studies have shown that fluorinated nanomaterials exhibit good stability during charge and discharge cycles, but their electrochemical performance has fallen short of expectations. Additionally, fluorinated carbon nanotubes have been prepared, which show capacities close to Li/CFx batteries.
Formation of Fluorinated Carbon Materials
The formation of CFx compounds with high F/C ratios typically requires higher fluorination temperatures, which lead to the formation of CF2/CF3 groups. However, these groups contribute to low electrical stability within a certain voltage range. New research has woven around the fluorinated carbon materials using a low-temperature fluorination method, which allows for the preparation of FNC compounds with F/C ratios ranging from 0.8 to 1.05.

Crystal Structure and Its Importance in Lithium Ion Transport
The crystalline structures of materials are pivotal in determining their physical and chemical properties, especially in battery and storage device applications. In this context, the compound known as ANC (Carbon Nanotubes) possesses a unique crystalline structure that contributes to a high level of structural integrity, helping to improve the transport of lithium ions (Li+). Maintaining the original structural integrity of the material during the fluorination process offers effective transport pathways that reduce the resistance resulting from electrical conductivity. Preserving the crystalline structure serves as a means to enhance the interfacial connection between fluorine and carbon, thereby boosting the electrical performance of the material through improved charge transport dynamics.
Furthermore, images derived from electron microscopy (HAADF-STEM) show a homogeneous distribution of fluorine and carbon. This property not only reflects structural integrity but also indicates effectiveness in utilizing active sites, which is considered a strong point for any materials used in lithium batteries. For example, consistent distribution of fluorine within the structure is crucial to avoid the emergence of any cracks or defects in the composition, thus enhancing the overall performance of the material in future applications.

Analytical techniques such as X-ray Diffraction (XRD) and Raman spectroscopy are prominent tools in understanding the structural properties of materials. X-ray diffraction patterns (XRD) for both ANC and FNC show clear signs of changes in the structural composition due to the fluorination process. This change manifests in the shifting of peaks associated with crystalline planes, where analysis reflects the changes in interlayer spacings, which serve as an indicator of the depth of fluorination. For instance, calculated values for interlayer spacings show a significant increase when transitioning from FNC-0.80 to FNC-1.05, reflecting notable changes in preparation techniques.
As for the Raman spectrum, differences between ANC and FNC in terms of the presence of distinct bands suggest a transformation of carbon into a more crystalline state following the fluorination process. This is achieved through measurements indicating the presence of alternative carbon compounds, which is a positive sign in energy applications, as these changes help improve performance and efficiency. The corresponding margins we observed could form an important basis for analyzing the electrical and magnetic conductivity properties of materials, especially when used in energy cells.
Performance
The Battery and the Effects Associated with the Fluorine-to-Carbon Ratio

For instance, the specific capacity data of FNC-0.80, FNC-0.90, FNC-1.00, and FNC-1.05 show high specific capacities exceeding 700 milliamp-hours per gram. In contrast, there is a reciprocal relationship between the fluorine-to-carbon ratio and the overall battery behavior. Energy storage capacity increases with a higher fluorine ratio, but at the same time, performance suffers from higher internal resistance.
This highlights the importance of achieving a balance between the amount of fluorine and the activity of the material. For example, experiments show that the effectiveness of the high-fluorine group may lead to a decrease in voltage due to oxidation-reduction reactions owing to the inferior properties of the fluorine groups. This complex relationship translates into significant variance in battery performance, where complex patterns tend to exhibit superb performance during rapid charge and discharge phases. Thus, this aspect raises an important issue in the field of developing materials for battery manufacturing, as future research needs to focus on enhancing the homogeneous distribution of fluorine groups while maintaining a balance in electrical performance.
