THIN BATTERY ELECTRODE GROUP, THIN BATTERY, AND ELECTRONIC DEVICE

摘要

Provided are: a high-capacity and highly flexible thin battery electrode group; a thin battery equipped with such an electrode group; and an electronic device with said thin battery embedded therein. The thin battery electrode group is provided with a sheet-like first electrode, sheet-like second electrodes that are laminated on both sides of the first electrode, and an electrolyte layer that is disposed between the first electrode and the second electrodes. The second electrodes have a different polarity than the first electrode. Further, the flexural modulus of the second electrodes is lower than the flexural modulus of the first electrode. The thin battery is provided with the thin battery electrode group, and a pouch-like exterior body that houses the electrode group. The electronic device is provided with a flexible electronic device body, and the thin battery is embedded in the electronic device body.
