Positive electrode active material comprising an agglomeration of at least two primary particles for lithium battery and lithium battery using the same

摘要

A positive electrode active material for lithium batteries includes secondary particles having primary particles and an amorphous material. A method of manufacturing the positive electrode active material includes mixing a lithium composite oxide and a lithium salt, and heat treating the mixture. A positive electrode includes the positive electrode active material, and a lithium battery includes the positive electrode.
