[0002] A battery is a device that can convert chemical energy into electrical energy. It is an electrochemical device that generates current through internal chemical reactions, thereby providing power for electronic devices or circuits. The basic battery structure usually includes two electrodes (positive and negative) and an electrolyte. Ions are conducted between the positive and negative electrodes through the electrolyte to form a current. When the battery is connected to an external circuit, an electrochemical reaction occurs between the positive and negative electrodes to generate current.
