▎ 摘　　要

NOVELTY - The high-conductance long-cycle lithium iron phosphate battery comprises positive electrode sheet, negative electrode sheet, a diaphragm and a electrolyte solution. The positive electrode sheet is carbon-coated aluminium foil coated with positive electrode slurry material including reduced graphene oxide-aluminum modified lithium iron phosphate. USE - Used as high-conductance long-cycle lithium iron phosphate battery. ADVANTAGE - The high-conductance long-circulating battery lithium iron phosphate has high capacity retention rate after multiple cycles, and high working performance at normal temperature and high temperature, and enhanced conductivity and service life of the battery. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation method of the lithium iron phosphate battery.
