Abstract
A lithium secondary battery having a longer life than conventional battery at a high temperature for electric power storage and electric vehicles is obtained. A lithium secondary battery having a long life at a high temperature can be obtained by using a material specified in Li/Mn atomic ratio, lattice constant, half value width, specific surface area, and average primary particle size as the positive electrode active material; and a material specified in density.
