Title:
NEGATIVE ELECTRODE FOR NONAQUEOUS ELECTROLYTE SECONDARY BATTERY AND BATTERY USING IT
Document Type and Number:
Japanese Patent JP2002117836
Kind Code:
A
Abstract:
To provide a nonaqueous electrolyte secondary battery which has a high capacity and which is superior in a cycle reversibility, by utilizing a large capacity in the maximum, which amorphous carbon and low crystalline carbon have.
A carbon material having an irreversible capacity of 100 parts by weight and lithium containing complex nitride of 20 to 150 parts by weight expressed in a general formula Li3-XMXN (M: at least one kind selected among the group consisting of Co, Ni, Mn or Cu, 0.2≤X≤0.8), is made to be contained in a negative electrode, thereby the irreversible capacity of the carbon material is compensated by the nitride.
