POWER STORAGE DEVICE, ELECTRODE, MANUFACTURING METHOD FOR ELECTRODE, AND MANAGEMENT METHOD

摘要

PROBLEM TO BE SOLVED: To evaluate a pre-doping time of an electrode in an electrical storage device.

SOLUTION: A mixing agent layer for an electrode is arranged on a hole-opening collector surface. For example, the mixing agent layer is made of an active material, a conductive auxiliary material, and a binder. The mixed agent layer having such the structure is formed in a slurry, and is coated on the collector surface. The electrode is manufactured by drying the coated mixed agent layer. The power storage device is assembled by using such an electrode. Lithium ions are pre-doped on a negative electrode at the time of assembling, and the pre-doping time is determined on the degree of air permeability of the electrode.
