Abstract
An anode material used for a lithium-ion battery utilizing a greater part of the storage capacity includes particles in outer dense layer, then inner layer, and then particle core. The outer dense layer is evenly enriched with an M element and an A element, the enrichment decreasing from the outside towards the core. The particle core does include the M element and the A element at a concentration greater than zero and having an average distribution. The M element includes Al, or Al and at least one of Mg, Ti, Zr, Mn. The A element includes F, or F and at least one of B, P, and N. A method for manufacturing the anode material and a lithium-ion battery are also disclosed.
