ELECTROCHEMICAL ENERGY SOURCE AND ELECTRONIC DEVICE PROVIDED WITH SUCH AN ELECTROCHEMICAL ENERGY SOURCE

摘要

Electrochemical energy sources based on solid-state electrolytes are known in the art. These energy sources, or 'solid-state batteries', efficiently convert chemical energy into electrical energy and can be used as the power sources for portable electronics. Nowadays, new application areas arise like implantables, small autonomous devices, smart cards, integrated lighting solutions or hearing aids. The invention relates to an improved electrochemical energy source and to an electronic device provided with such an electrochemical energy source, and whereby the volume change of the anode and cathode electrode assembly is minimised during charging and discharging of the battery cell.
