▎ 摘　　要

NOVELTY - Preparing lithium-ion battery safety primer slurry comprises (i) preparing partial graphene oxide, (ii) taking partial graphene oxide surface grafted with active lithium branches, and (iii) processing the material to prepare the safe bottom coating slurry. USE - The lithium-ion battery is useful for current collector (claimed). ADVANTAGE - The method has reduces the safety accident of short circuit trigger the electric core, corresponding speed is fast, improves the safety of lithium-ion battery, improves the electric core puncture rate, avoiding explosion, heat and other serious accident. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: lithium-ion battery safety primer slurry, obtained by the above-mentioned method; and current collector, comprising lithium-ion battery safety primer slurry coated on both sides of the current collector and dried.
