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

摘要

Electrochemical energy source comprising a stack of mutliple cells each provided with current collectors. A control unit can selectively electrically connect the current collectors so as to obtain a voltage suitable for powering an electronic device. The electronic device and the electrochemical energy source can be formed on the same substrate. The electrochemical energy source is preferably a Li-ion battery.
