  • Patent number: 9401510
    Abstract: A lithium accumulator with a housing includes at least one cell with two electrodes provided with current collectors and separated by a separator. Each electrode, free of organic binders, is pressed down onto both sides of the current collector made of a perforated metal strip in the form of metal network, expanded metal or perforated metallic foil. The minimum thickness of the electrodes is three times the thickness of the perforated metal strip.
    Type: Grant

  • Patent number: 9203123
    Abstract: A lithium accumulator containing positive and negative electrodes with a minimum thickness of 0.5 mm, separated by separators, where each electrode is deposited into a hole in a frame, as a part of a set of frames arranged in a stack between marginal covers, with electrical insulation between the frames of opposite electrodes and additional current collectors between identical electrodes, wherein each frame comprises at least one channel for passage of a heat exchange media and the channels of the individual frames are interconnected. Liquid accumulator electrolyte may be used as a heat exchange media.
