Abstract
A charging apparatus for a lithium-ion secondary battery in which a cathode, an anode, and an electrolyte are housed in a battery case, includes an electrode shape changing unit that physically changes the shape of at least one electrode of the cathode and the anode at the time of charging or discharging the lithium-ion secondary battery so as to expand at least a part of a void which is formed in the electrode and which is to be penetrated by the electrolyte, and restores the physically changed shape of the electrode after charging or discharging the lithium-ion secondary battery.
