FIELD: electricity.
SUBSTANCE: claimed invention is related to negative electrode for lithium-ion accumulator battery and method of its manufacturing. The negative electrode has current tap and a layer of active material formed at the current tap surface, which contains particles of active material for the negative electrode. In the layer of active material for the negative electrode between active material particles insulating material is placed so that conductivity by percolation is not developed in the whole layer of active material for the negative electrode.
EFFECT: improvement of efficiency for prevention of short-circuit current occurrence due to inner short circuit and heat generation due to passage of the above current in the accumulator battery at maintenance of the battery performance.
