Abstract
A lithium secondary battery includes an anode, a cathode and a separator containing non-aqueous electrolytic solution or solid-state electrolyte, interposed between the anode and the cathode. The anode comprises, as an active material, lithium metal, lithium alloy or a material capable of absorbing and desorbing lithium ions. The cathode comprises spinel-structured lithium-manganese complex oxide as an active material. The spinel-structured lithium-manganese complex oxide is in the form of hollow spherical particles formed by sintering single crystal particles.
