摘 要: 综述了铋对铅酸蓄电池析氢和析氧行为的影响。虽然关于铋对析氢和析氧影响的研究较多,但铋在电池中的作用仍存在争议。大多数结果表明,铅铋合金中铋对正极氧气的析出起电催化作用,同时又加速了氧在负极上的再复合效率,对负极氢气析出反应则起抑制作用,电解液中的铋离子的存在能提高析氢析氧过电位。铋的存在降低了电池的水损耗。 Recent research and development of the influence of bismuth on hydrogen and oxygen evolution reactions in leadacid battery were reviewed.Up to now there were still controversial conclusions on the effect of bismuth on hydrogen and oxygen evolution in lead-acid battery. Most results showed that bismuth in the alloys could catalyze the oxygen evolution on positive plate but increase the recombination rate of oxygen on negative plate and speed up the rate of hydrogen evolution.However,Bi3+ions in the electrolyte could enhance the hydrogen and oxygen overpotentials on the negative and the positive plate respectively,and therefore decreased the water loss of leadacid battery.
