同时添加Ba和Co对镍电极性能的影响

The Effects of Ba and Co on Electrochemical Performance of Nickel Electrode

研究了Ba和Co同时添加对镍电极和MH/Ni电池电化学性能的影响,结果表明:Ba和Co同时添加与单添加Co相比更进一步提高了镍电极的析氧电位,从而提高了镍电极的充电效率和MH/Ni电池的放电容量和大电流放电能力。

The effects of Ba and Co addition on electrochemical performance of nickel electrode and MH/Ni battery were studied. The results showed that the oxygen - evolution potential and the discharging depth of the nickel electrode were improved by the addition with both Ba(OH)2 and Co (OH) 2 compared with adding Co(OH)2 only. The capacity of Ni/MH battery has also been increased due to the utilization of active material for positive electrode.
