Abstract:
A process for producing a positive electrode for a secondary battery, said process comprising:(a) calcining a raw material containing a lithium compound under an oxidizing atmosphere to produce calcined powders; (b) forming said calcined powders to a shape of an electrode after incorporating organic fibers or organic polymer particles thereinto; and (c) calcining the formed calcined powders under the oxidizing atmosphere, thereby obtaining a porous sintered positive electrode; wherein the calcining in step (a) of the raw material is conducted at a temperature lower than the temperature of calcining in step (c) of the formed powders; and wherein the calcining of the raw material in step (a) is conducted for a period of time less than the period of time of calcining in step (c) of the formed powders.
