Kind Code:
A1
Abstract:
Disclosed are a method and system for charging a lithium-ion secondary battery provided with: a positive electrode containing a positive-electrode active material that can absorb, store, and release lithium ions; a negative electrode containing an alloy negative-electrode active material that can absorb, store, and release lithium ions; a separator interposed between the positive electrode and the negative electrode; and a non-aqueous electrolyte solution. The state of charge and temperature of the lithium-ion secondary battery are measured, and said lithium-ion secondary battery is charged until a reference voltage (E1) associated in advance with said state of charge and temperature is reached.
