▎ 摘　　要

NOVELTY - A high thermal conductivity phase change composite conductive agent comprises porous graphene substrate, and adsorbed matrix phase and graphene oxide phase with variable nanocapsules. USE - High thermal conductivity phase change composite conductive agent for use in lithium ion battery (claimed). ADVANTAGE - The agent has high thermal efficiency, high specific energy and better conductivity, and can quickly absorb large amounts of heat generated at the time of abuse testing, and effectively reduces the temperature rise of the battery to prolong battery life. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a lithium ion battery comprising high thermal conductivity phase change composite conductive agent.
