✦ Synopsis

In Japanese)

The batteries discussed are lithium batteries. The preparation of the anodes, which are composed of highly conductive carbonaceous material grains coated with a glassy or graphitized carbon layer, comprises applying a precursor of the carbon layer to a powdered carbonaceous material and sintering at S(k)-3000°C in a non-oxidizing atmospheric The precursor is preferably organic, selected from polycarbodiimides, phenolic resin, pitch, coal tar, coke, furan resin, polyactylonitrile. rayon, and polychloroacrylonitrile. The carbonaceous material is graphite, ketjen black, carbon black, acetylene black, or glassy carbon.
