NEGATIVE ELECTRODE MATERIAL, PREPARATION METHOD THEREOF, AND ELECTROCHEMICAL APPARATUS

原文（中国語）

A negative electrode material includes: a core, where the core includes silicon-based particles; a first layer containing carbon, where the first layer is on an outer side of the core; a second layer containing a first conductive material and an organic lithium salt, where the second layer is on an outer side of the first layer; and a third layer containing a second conductive material and a polymer, where the third layer is on an outer side of the second layer, thereby alleviating volume swelling of the electrochemical apparatus after cycling and improving cycling performance of the electrochemical apparatus.
