  • Miniature battery with constant electrode pressure and electrolyte reservoir
    Patent number: 11289702
    Abstract: An electrochemical voltage source has an anode containing lithium, a cathode containing manganese oxide, and a housing. The cathode and the anode are arranged in an interior of the housing and are arranged opposite one another. An electrolyte reservoir in the form of a compressible storage body, which receives an electrolyte, is arranged between the anode and the cathode. The storage body has a first side resting against an end face of the cathode and a second side, which faces away from the first side, and rests against an end face of the anode. The cathode experiences an increase in volume when the voltage source is discharged. The anode experiences a decrease in volume during the discharge. During the discharge, the absolute value of the volume increase of the cathode is at least as great as the absolute value of the volume decrease of the anode.
