Title:
NEGATIVE ELECTRODE ACTIVE MATERIAL FOR LITHIUM ION SECONDARY BATTERY, AND LITHIUM ION SECONDARY BATTERY
Document Type and Number:
WIPO Patent Application WO/2016/075798
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a particularly high-capacity and long-lasting negative electrode active material for lithium ion secondary batteries. In the negative electrode material, which is for lithium ion secondary batteries and which includes silicon nano-particles and silicon nano-wires, the silicon nano-particles and the silicon nano-wires are bonded together. More preferably, in the negative electrode active material for lithium ion secondary batteries, the surfaces of the silicon nano-wires or the silicon nano-particles are covered with carbon coating layers.
