Method of manufacturing lithium ion storage device

摘要

There is provided a method of manufacturing a lithium ion storage device. A lithium ion storage device (10) produced by the method includes a positive electrode (18) having a positive electrode active material (22) that contains a lithium-containing compound, and a negative electrode (12) having an alloy-based negative electrode active material (16). A charge potential in a first cycle is higher than charge potentials in second and subsequent cycles.
