▎ 摘  要

NOVELTY - A carbon material-assisted fast ion conductor modified cobalt-poor ternary anode material comprises lithium-nickel-cobalt-manganese oxide-coated lithium-chromium-titanium phosphate. The molar ratio of lithium-nickel-cobalt-manganese oxide and lithium-chromium-titanium phosphate is 1:0.01-0.1. USE - Carbon material-assisted fast ion conductor modified cobalt-poor ternary anode material. ADVANTAGE - The carbon material-assisted fast ion conductor modified cobalt-poor ternary anode material has excellent electrolyte corrosion resistance and cycle performance, and high conductivity and ion transmission rate. The collapse of the cobalt-poor anode material structure is prevented. DETAILED DESCRIPTION - A carbon material-assisted fast ion conductor modified cobalt-poor ternary anode material comprises lithium-nickel-cobalt-manganese oxide (LiNixCoyMnzO2, where x is 0.6 to less than 1, y is more than 0 to 0.1 or less, z is more than 0 to 0.3 or less, and sum of x, y and z is 1)-coated lithium-chromium-titanium phosphate (Li2-mCr1-mTi1+m(PO4)3, where m is 0-0.8). The molar ratio of lithium-nickel-cobalt-manganese oxide and lithium-chromium-titanium phosphate is 1:0.01-0.1.
