ELECTRODE AND ELECTRIC ACCUMULATING DEVICE FOR LEAD-ACID SYSTEM Russian patent published in 2016 - IPC H01M4/96 H01M4/583 H01M10/06 

FIELD: physics.

SUBSTANCE: invention relates to electrodes of lead-acid accumulator batteries and methods of their production. In particular, electrodes contain active accumulator material for lead-acid battery, wherein surface of electrode is equipped with coating layer containing carbon mixture from composite carbon particles, each of composite carbon particles contains particle of first capacitor carbon material and particle of second conductive carbon material, wherein particle size of first material is considerably more than that of particles of second electrically conductive carbon material, and at least 20 % of surface of first capacitor material is coated with particles of second electrically conductive carbon material.

EFFECT: improved cyclic resource lead-acid battery electrodes which are coated with said material is technical result of invention.
