▎ 摘 要
NOVELTY - Reduction of resistivity of graphite electrode/joint comprises using graphite electrode/linker as substrate, graphene slurry as spraying agent, and graphene prepared from supercritical carbon dioxide graphene; spraying or dipping and drying or roasting to prepare graphite electrode/joint product. USE - Method for reducing resistivity of graphite electrode/joint (claimed). ADVANTAGE - The method has simple operation and no additional power consumption, and reduces current overload and breaking rate.
