OPTIMISED DEVICE OF POWER ACCUMULATION Russian patent published in 2012 - IPC H01M10/06 

FIELD: electricity.

SUBSTANCE: lead-acid battery comprises a negative electrode, comprising an electrode material of a battery on the basis of lead and an area of a capacitor material lying above the battery electrode material on the basis of lead. Each electrode is in electric connection with one external output of the battery, and at least one positive battery electrode on the basis of lead dioxide, besides, each positive electrode is in electric connection with the second external output of the battery, a separator installed between electrodes facing each other, electrode filling at least the space of these electrodes and separators, at the same time the capacitor material lying above the battery electrode material on the basis of lead contains 20-65 wt % of carbonaceous material with high electric conductivity, 30-70% carbonaceous material with high specific area of the surface, at least 0.1% of lead and a binder.

EFFECT: higher service life and improved performance properties.
