COMPOSITE ELECTRODE AND ELECTRONIC DEVICE INCLUDING THE SAME

摘要

A composite electrode includes a plate-shaped conductor; a plurality of auxiliary electrodes disposed such that ends of the plurality of auxiliary electrodes are connected to a surface of the plate-shaped conductor and the plurality of auxiliary electrodes extend from the surface of the plate-shaped conductor; and an active material layer formed between the plurality of auxiliary electrodes so as to be in contact with the plate-shaped conductor. When the height of the plurality of auxiliary electrodes is defined as h, the center-to-center spacing of auxiliary electrodes facing each other in the plurality of auxiliary electrodes or the spacing of auxiliary electrodes facing each other in the plurality of auxiliary electrodes is h or more and 2h or less.
