Working principle and charging and discharging characteristics of Ni-MH battery
1. The working principle of Ni-MH batteryThe Ni-MH battery is an alkaline storage battery with metal hydride as the negative electrode, NiOOH as the positive electrode, and KOH aqueous solution as the electrolyte. The electrochemical formula is:(-)M/MH| KOH(6mol/L)|Ni(OH)2/NiOOH(+) hydrogen storage alloy has the function of absorbing and releasing hydrogen when the potential changes. The battery […]
