The inhibiting effect s of additives in 40 % KOH solution and it s in fluence on performance of zinc elect rode were investigated by met hods of hydrogen evolution experiment , AC impedance measurement and SEM examination , etc . The corresponding mechanism of N Y was also discussed simply . The result s show t hat N Y inhibit s corro sion and dendrite growt h of zinc elect rode had little effect on dis charging performance . It s inhibiting effect was explained by adsorption mechanism . Key words : inhibitor ; rechargeable alkaline zincmanganese dioxide battery ; mercuryfree ba
