Anhydrous secondary electrical battery cell - has carbon material processed and purified to form a fibre for use as negative electrode base in battery

An anhydrous secondary battery cell is produced using an anhydrous electrolyte that contains alkaline metal salt in a solution together with a negative electrode with a carbon material. The carbon source material is heated and filtered to produce a tar that is purified and distilled. The material is...

More Information
Summary:An anhydrous secondary battery cell is produced using an anhydrous electrolyte that contains alkaline metal salt in a solution together with a negative electrode with a carbon material. The carbon source material is heated and filtered to produce a tar that is purified and distilled. The material is processed to form a fibre to create a negative electrode for use in the battery cell. USE/ADVANTAGE - Improved negative electrode for long life operation
