BATTERY DESIGN Russian patent published in 2020 - IPC H01M2/14 H01M10/52 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering, namely to the flat and flexible lithium battery design, which can be used in portable electronic devices. Battery design includes a first current-carrying layer, a first active material layer, a separating layer, a first plastic frame, a second active material layer and a second current-receiving layer, wherein first layer of active material is located on first current-receiving layer, separating layer is located on first layer of active material and completely covers upper surface of first layer of active material, first plastic frame is arranged on side wall of separation layer, and the upper part of the first plastic frame has a protruding part, which extends to the upper surface of the separating layer. Besides, second layer of active material is located on separating layer and protruding part, wherein second layer of active material is isolated from first layer of active material by separating layer and protruding part by first plastic of frame, second current-receiving layer is located on second layer of active material.

EFFECT: reduced degree of lithium dendrites formation, as well as maintenance of safety and stability of electric characteristics of the battery is the technical result of the invention.
