ELECTRODE MATERIAL FOR LITHIUM SECONDARY BATTERY, ELECTRODE STRUCTURE, AND SECONDARY BATTERY

摘要

PROBLEM TO BE SOLVED: To provide an electrode material for a lithium secondary battery having high capacity, an electrode structure having the same electrode material, and a secondary battery having the same electrode structure.

SOLUTION: The electrode structure 402 is formed on a current collector 400 by preparing an electrode material layer 401 made of negative electrode material powder. Upon forming fine particles of the electrode material forming the electrode material layer 401 by an alloy including silicone of 50 weight% or more and also including tin and transition metal, the quantity of electricity to be accumulated or discharged can be obtained at high capacity of 2700 mAh/g or more per electrode material weight.
