ZINC-NICKEL ACCUMULATOR Russian patent published in 2009 - IPC H01M10/30 H01M2/14 

FIELD: electricity.

SUBSTANCE: invention is attributed to alkaline accumulators, specifically to zinc-nickel accumulators. In this invention zinc-nickel accumulator comprises casing, alkaline ionogen solution, positive and negative electrodes separated by multilayer separator and porous metal inserts located in multilayer separator between positive and negative electrodes. In this structure the said metal inserts are electrically connected among themselves or made as single zigzag tape the zigs of which are located in multilayer separator between positive and negative electrodes. Edges of separate inserts or edges of single tape zigs can protrude out of separator for 1÷1.5 mm. Capron separator is used at positive electrodes and separator made of nonwoven polypropylene and alkali-proof paper is used at negative electrodes. The insert can be made of nickel foil 50÷60 micron in thickness and with porosity of 40÷50%. Zincate ionogen obtained from reaction of 50 g of ZnO with 1 l "КОН" with specific density of 1.3 g/cm³ is taken as electrolyte.

EFFECT: improvement of resource and electric characteristics.
