Electrodes for power storage devices, power storage devices, air batteries and all-solid-state batteries

摘要

PROBLEM TO BE SOLVED: To provide an electrode for a power storage device, occluding a sufficiently large amount of metal ions per weight.SOLUTION: An electrode 10 for a power storage device includes: a current collector plate 20 comprising a metal having a first main surface 21 and a second main surface 22 on an opposite side to the first main surface 21; and an electrode layer 30 provided on the first main surface 21 and/or the second main surface 22. The electrode layer 30 comprises an active material layer consisting of only silicon and a binder binding the active material.SELECTED DRAWING: Figure 1
