New advanced subfluorated carbone (CFx) for advanced Lithium Carbon Monofluorated (Li-CFx)

Technology

The technology was developed during the last 10 years in the ICCF laboratory and led to the release of 2 patents. The materials are advanced nanofiber fluorinated carbon (CFx) within a stoichiometry inferior to 1. The specific method developed by the laboratory presents the advantage to segregate a CFx phase and a pur carbon phase that contribute to improve the performances in term of power, capacity and initial so called « delay effect ». The management of the fluorination allows a large range of CFx from CF0.2 to CF1 depending on the application targeted.

Market targeted

 All the actual Li/CFx applications:

- Standard button cells
- Medical market
- Military and space market
- Oil drilling market

within the perspective to widen to medium range current applications (smart meter) thanks to power improvement compare to standard CFx.

Main Advantages

• High capacity recovery compare to theory
• Possibility to define the right amount of fluorination depending on the application targeted
• No initial voltage drop that could increase cold discharge
• No need of carbon additive that lead to increase the overall cell capacity
• Higher power performances leading to improve the well-known heating cell phenomena during discharge.
• Already under evaluation by the world’s leading designer and manufacturer of advanced-technology batteries for industry
