NOVELTY - Active material anode comprises matrix particles comprising lithium metal oxide and a graphite coating layer covering at least part of the surface of the matrix particles, where the lithium metal oxide has a structure shown in Lin-yNayCo1-aMaO2 (I), where in the X-ray diffraction spectrum, the lithium metal oxide is the Cmca space group of the cubic crystal system, and has 002 peak with 2θ of 17.9-18.1°, and 131 peak with 2θ of 67-67.5°, where n = 0.6-0.8, y = 0-0.05, and a = 0-0.2, and where M is a doping element. USE - Used as active material anode. ADVANTAGE - The anode: improves the specific capacity and cycle performance of the battery by special composition and crystal phase structure of cathode active material; and makes the battery perform well under high pressure conditions. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: a anode sheet, comprising active material anode; and a lithium-ion battery, comprising anode sheet.
