Title:
LITHIUM SECONDARY BATTERY
Document Type and Number:
Japanese Patent JP2001135312
Kind Code:
A
Abstract:
To provide a lithium secondary battery which can keep electron con ductivity in a low potential region, to make smooth discharging response of lithium manganate oxide such as lithium manganate, threrby to improve the discharging capacity.
Lithium manganate oxide shown in a general formula: LixMn2-yMyO4 (where M is at least one element selected among Co, Ni, Fe, Mg, Cr, Ba, Ag, Nb, and Al, and x and y are respectively 0<x≤2, 0≤y<2) is compounded with 0.01 to 3.0 wt.% of poly-pyrrole for making a main active material contained in a positive electrode which is carried by a collector body for forming a positive electrode.
