Electrochemical device e.g. refillable battery for use in e.g. watch application, has anode and cathode that are placed between separator and current collector, where collector is made of partially amorphous material including metal element

摘要

The device has a cathode (2) and an anode (4) that are separated by a separator (6) made of polymers or composites. The anode and the cathode are placed between the separator and one of a set of current collectors (8). One of the collectors is made of partially amorphous material including a metal element. An electrolyte is utilized for exchanging ions between the cathode and the anode. The electrolyte is directly integrated into the separator that acts as a porous separator in which pores are filled with liquid or gelled electrolyte.
