Abstract

Zinc-air- or O2-accumulators contain an aq. alkaline electrolyte which contains a Zn ion source and an additive which is polyethylene imine and/or copolymers of polyethylene imine with ethylene oxide and/or propylene oxide, the oxide part of the copolymer being =90wt.% of it. The additive has a solubility of >=10-50 ppm. in the electrolyte. The accumulators are rechargeable, giving a good Zn coating on the cathode with no dendrites.
