摘要:  针对Ni-MH电池充电过程中氧的产生和不恰当的消除方式带来的内压升高和热量聚积使电池总体性能衰减很快的问题,合成了电化学催化剂磺化酞菁铁并将其添加到合金粉中做成电池。磺化酞菁铁的加入能够活化电池充放电过程中产生的气体,加速气体的消除,从而使内压升高速度显著降低,较为显著地提高镍氢动力电池的整体性能。使用Dmol3软件对磺化酞菁铁活化气体过程进行模拟分析,模拟结果验证了催化剂的催化作用,并给出催化机理的合理解释。

Abstract: In Ni-MH battery, oxygen evolution causes a high inner pressure during charge and overdischarge, and an inappropriate eliminating way of the oxygen in the battery results in accumulation of heat. This is the main obstacle to develop and apply high capability and high power battery. In this paper, iron-tetrasulfphthalocyanine was prepared and added into batteries as an electrochemical catalyst. Experimental results show that iron-tetrasulfphthalocyanine can effectively activate the gases which are produced during charge in Ni-MH battery, therefore decrease the reduction potential of Oxygen and the oxidation potential of Hydrogen. And the performance of battery was improved significantly. With the aid of DMol3 software, the activation of oxygen and hydrogen by iron-tetrasulfphthalocyanine was simulated and analyzed. From the calculated results the activation process gets a reasonable explanation.
