FIELD: anodic material for lithium accumulator.
SUBSTANCE: in accordance to invention, anodic material contains a layer of metallic or metalloid core, capable of repeating reaction of alloying/de-alloying by lithium; a layer of amorphous carbon, covering the surface of layer of metallic or metalloid core, and a layer of crystalline carbon, covering the layer of amorphous carbon. Anodic material demonstrates high charge/discharge capacity, due to advantage of metal-based anodic material, and prevents changing of volume of layer of metallic or metalloid core, resulting from repeating reaction of alloying/de-alloying by lithium, due to a layer of amorphous carbon and a layer of crystalline carbon.
EFFECT: improved cyclic characteristics and resource of accumulators.
