ACCUMULATOR BATTERY WITH NON-AQUEOUS ELECTROLYTE Russian patent published in 2015 - IPC H01M10/52 H01M2/16 H01M4/13 

FIELD: electricity.

SUBSTANCE: according to the invention accumulator battery with non-aqueous electrolyte has energy-generating element (21) with layer (19) of accumulator, which includes a positive electrode with active material layer (15) of the positive electrode formed at surface of current tap (12) of the positive electrode, a negative electrode with active material layer (13) of the negative electrode formed at surface of current tap (11) of the negative electrode, and separator (1) placed between the positive and negative electrodes and containing non-aqueous electrolyte. The RA (=Rzjis(2)/Rzjis(1)) ratio between surface unevenness (Rzjis(1)) of the active material layer of the negative electrode at the side contacted with the separator and surface unevenness (Rzjis(2)) of the separator surface at the side contacted with the active material layer of the negative electrode varies from 0.15 up to 0.85.

EFFECT: high dynamic coefficient of friction is obtained and thus occurrence of lay-up misalignment may be prevented at the stage of layering during manufacture of the accumulator battery with non-aqueous electrolyte.
