Abstract:
A cathode for a lithium secondary battery includes a cathode current collector, and a cathode active material layer on the cathode current collector. The cathode active material layer includes a plurality of a lithium-metal oxide particle that has a shape of a single particle. An activation energy (Ea) of the cathode is in a range from 50 kJ/mol to 80 kJ/mol.
