阀控式铅酸电池用催化装置

Discussion on the application of catalysts to VRLA batteries

简短地回顾了中国催化消氢电池的过去。对于传统富液式电池的催化消氢装置 (催化栓 )由于气体量大 ,催化反应热效应大 ,容易造成催化剂烧灼 ,还往往容易中毒 (因锑合金富液电池内有锑化氢 ) ,也因使用状态的缘故 ,会造成催化剂湿润 (受潮 )而失效。2 0世纪 70年代 ,阀控电池问世 ,中国相继在 80年代 ,在电力、电信、UPS等领域成功地使用阀控电池替代了传统的富液式电池。直到目前为止 ,本来一个长寿命的阀控电池在实用中却未能真正长寿命 ,究其原因诸多。一个催化装置用于阀控电池 ,能够治疗“多病”的阀控电池 ,有助于真正实现长寿命阀控电池设计。因此 ,有必要在理论上深一层认识催化装置 ,特别是用于阀控电池的催化装置。

The history of catalysts used for traditional flooded lead acid batteries in China was briefly reviewed.In order to provide the cure for sickly VRLA batteries currently used,and make them into long life,stable and balancing ones,the author believes that one of the acceptable solutions is to incorporate catalysts into VRLA batteries.The cause and effect of this practice were elaborated in this paper.
