▎ 摘　　要

NOVELTY - A lithium ion battery positive pole piece material preparation method involves preparing a lithium iron phosphate positive pole material as a ready-made product, coating chemical plating metal aluminum elemental iron phosphate lithium surface, preparing lithium iron phosphate-graphene composites, and followed by coating a positive pole piece with metallized aluminum single chemical substance. USE - Method for preparing lithium ion battery positive pole piece material. ADVANTAGE - The method enables preparing lithium ion battery positive pole piece material with better lithium iron phosphate material doped graphene conductivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a lithium ion battery positive pole piece material.
