FIELD: electricity.
SUBSTANCE: invention relates to electrical engineering, particularly to design of an accumulator with an efficient heat exchange system. Lithium battery comprising positive and negative electrodes with a minimum thickness of 0.5 mm, separated by separators, wherein each electrode is placed in opening of a frame, said frame being formed between peripheral pile caps with electrical insulation between said frames of electrodes of opposite polarity and current collectors additional electrodes between same polarity, is arranged so that each frame (3), provided with openings in which electrodes and comprises at least one channel (32) for passage of a heat exchange medium, wherein channels (32) of individual frames (3) are connected with each other, and heat transfer medium used is a liquid battery electrolyte.
EFFECT: high mechanical stability of accumulator with increased heat exchange inside accumulator with optimisation of cooling system.
