Title:
ELECTRODE MATERIAL FOR NEGATIVE POLE OF LITHIUM SECONDARY CELL, ELECTRODE STRUCTURE USING SAID ELECTRODE MATERIAL, LITHIUM SECONDARY CELL USING SAID ELECTRODE STRUCTURE, AND METHOD FOR MANUFACTURING SAID ELECTRODE STRUCTURE AND SAID LITHIUM SECONDARY CELL
Document Type and Number:
WIPO Patent Application WO/2000/017949
Kind Code:
A1
Abstract:
An electrode material for a negative pole of a lithium secondary battery containing particles which comprises and amorphous M•A•X alloy having a substantially non-stoichiometric composition, wherein M represents at least one element selected from the group consisting of Si, Ge, and Mg, A represents at least one element selected from the transition metal elements, X is an optional component and represents at least one element selected from the group consisting of O, F, N, Ba, Sr, Ca, La, Ce, C, P, S, Se, Te, B, Bi, Sb, Al, In, and Zn, and the content of the component M [M/(M+A+X)] is 20 to 80 atomic %. An electrode structure for a lithium secondary cell composed of the aforementioned electrode material for a negative electrode and a collector comprising a material which forms no alloy with lithium in an electrochemical reaction. A lithium secondary cell having a negative pole comprising the electrode structure.
