CURRENT LEAD FOR BIPOLAR LITHIUM-ION BATTERY Russian patent published in 2015 - IPC H01M4/66 H01M4/70 H01M10/525 H01M10/585 

FIELD: electricity.

SUBSTANCE: according to the present invention the suggested current lead (3) for bipolar lithium-ion batteries includes the first conductive layer (3A), which is obtained by adding conductive filling material to the base containing resin with imide group; and the second conductive layer (3B), which performs function of lithium ions isolation (blocking). The second conductive layer (3B) includes the following: resin-based insulating layer (3a), which is obtained by adding conductive filling material to the base non-containing resin with imide group; and metal-based layer (3b). This current lead (3) for bipolar lithium-ion batteries is used do that the first conductive layer (3A) is at the side of active material layer at positive electrode in regard to the second conductive layer (3B).

EFFECT: reduced absorption of lithium ions inside the current lead and increased resistance to recharge and discharge is technical result of the invention.
