Innovation mobile Researchers of USA create electrodes that could charge batteries in a few seconds: MXenes Common models of batteries are composed of two electrodes, which are electrochemical cells, one with positive charge (cathode) and one with negative charge (anode). The electrodes are electrical conductors used to make contact with the electrolytes, which allow the ions to move between the electrodes so that the current flows out of the battery.
