FLEXIBLE LITHIUM BATTERY Russian patent published in 2020 - IPC H01M10/52 H01M10/585 H01M2/16 H01M4/66 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering, namely to a flexible lithium battery, which can solve the problem of short circuit caused by separation of the current-sinking layer and active material layer during the battery bending. In disclosed battery, comprising first current-sinking layer and second current-sinking layer, wherein first current-sinking layer has first outer surface and first inner surface, and second current-sinking layer has second outer surface and second inner surface, between the first inner surface and the second inner surface there is an adhesive frame for forming a sealed and closed space in which a layer of the electrochemical system is located, wherein the layer of the electrochemical system comprises a first layer of active material, second layer of active material and electrically insulating layer arranged between first active material layer and second layer of active material, and there is a flexible bonding layer disposed between the first inner surface and the first active material layer and / or between the second inner surface and the second active material layer, wherein said flexible bonding layer consists of an adhesive base and an electrically conductive additive, wherein the adhesive base consists of a linearly structured colloid and a stereoscopically structured colloid.

EFFECT: technical result of invention is improvement of battery operation reliability at its repeated bending.
