▎ 摘　　要

NOVELTY - Cathode material comprises 3-35 wt. % of nano-metal or fumed spherical nano-graphene, 65-97 wt.% of nano-metal alloy, 0.1-15 wt.% of conductive polymer and 0.1-15 wt.% of water-soluble adhesive agent. USE - Cathode material for lithium battery. ADVANTAGE - The cathode material with a gap which can be made large to increase cycle life of lithium battery to greater than or equal to 2000 times. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing cathode material which involves incorporating nano-graphene or nano-metal and nano-metal alloy in conductive polymer through high-speed emulsifying machine followed by adding with water-soluble adhesive agent to obtain desired cathode material.
