XO_2对铅酸蓄电池正极材料的影响

Influence of XO_2 additive on positive material of lead-acid

铅酸蓄电池凭借其优良的性能价格比,在蓄电池领域中占有非常重要的地位。使用XO2作为铅酸蓄电池正极添加剂,对空白试样和含添加物的正极材料进行了研究,以自制的小型电池通过恒流放电,考查了不同含量XO2对铅酸蓄电池的影响。结果表明,加入0.1%～0.3%XO2可以提高电池的放电容量及正极活性物质的利用率,延长电池的循环寿命。

Lead-acid batteries play an important role in secondary batteries due to its high ratio of performance to cost. XO2 was used as anode additive in lead-acid. Its effect on lead paste was studies through constant current discharge with self-made batteries. The results show that the utilization of anode active material, capacity can be increased by 0.1%-0.3% XO2. At the same time,cycle life was remarkable improved.
