BATTERY HAVING ELECTRODES IN FORM OF COATING DEPOSITED DIRECTLY ON NANOPOROUS SEPARATORS Russian patent published in 2014 - IPC H01M2/14 H01M10/38 

FIELD: electricity.

SUBSTANCE: disclosed are lithium batteries, having (a) a separator/cathode assembly, having a cathode current collector layer situated between a first cathode layer and a second cathode layer and a porous separator layer on the side of said first cathode layer, wherein said first cathode layer is coated directly on said separator layer; (b) a separator/anode assembly, having an anode current collector layer situated between a first anode layer and a second anode layer and a porous separator layer attached on the side of said first anode layer, wherein said first anode layer is coated directly on said separator layer; and (c) an electrolyte, wherein said battery comprises alternating layers of said separator/cathode assembly and said separator/anode assembly. In the preferred version, separator/cathode assembly and separator/anode assembly sections are not in contact with each other and electric connections of the edges are made through said sections. Methods of making said batteries are also disclosed.

EFFECT: high energy and power density of lithium batteries with high efficiency of production thereof.
