NOVELTY - Aqueous anode of lithium ion battery, comprises 90-98 wt.% lithium iron phosphate, 0.1-1.2 wt.% polyacrylonitrile emulsion, 0.1-3 wt.% binder with hydrophilic and lipophilic bipolarity, 0.5-3 wt.% aqueous conductive paste and 30-40 wt.% first deionized water and aqueous conductive paste contains 0.1-1.5 wt.% carbon nanotubes, 0.1-1 wt.% graphene, 0.5-2 wt.% carbon black, 0.1-0.5 wt.% polyvinylpyrrolidone, 0.1-0.5 wt.% carboxymethyl cellulose, 59-60 wt.% second deionized water and 100 wt.% solids. The polyacrylonitrile emulsion is a polyacrylonitrile emulsion and the hydrophilic-lipophilic bipolar binder is a styrene-acrylic emulsion. The solid comprises lithium iron phosphate, carbon nanotube, carbon graphene, polyvinylpyrrolidone and carboxymethyl cellulose. USE - Used as aqueous anode of lithium ion battery. ADVANTAGE - The lithium ion battery aqueous anode slurry is environment-friendly, low cost, and has high compaction density. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for the preparation method of aqueous anode of lithium ion battery.
