Title:
POSITIVE ELECTRODE ACTIVE MATERIAL FOR NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY, PROCESS FOR PRODUCTION OF SAME, AND NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY PRODUCED USING SAME
Document Type and Number:
WIPO Patent Application WO/2011/111377
Kind Code:
A1
Abstract:
In the synthesis of lithium nickel oxide, a burning aid is added to a burning material. In this manner, the crystal growth of lithium nickel oxide can be accelerated at a lower temperature than a burning temperature that is required for achieving the desired crystal growth of lithium nickel oxide, and the substitution-type introduction of an element involved in the stabilization of the structure of lithium nickel oxide into crystals of lithium nickel oxide can be accelerated. Further, the occurrence of the distortion of the crystals or the oxygen deficiency during the synthesis can be prevented, whereby a lithium ion secondary battery having excellent charge/discharge properties and excellent cycle properties can be provided.
