WIPO Patent Application WO/2023/182269
Kind Code:
A1
Abstract:
This electrochemical device includes a winding body (1) constituted by a belt-shaped cathode (2) that contains activated charcoal as a cathode active material; a belt-shaped anode (3); and a belt-shaped separator (4). The winding body (1) includes a winding shaft section (1a) sandwiched and formed between winding shafts; and a winding section (1b) connected to the winding shaft section (1a). The winding shaft section (1a) includes a portion on one end side of the anode (3) and a portion on one end side of the separator (4). In the winding body (1), the cathode (2), the anode (3), and the separator (4) are wound such that both surfaces of the cathode (2) lie opposite the anode (3).
