硅粉閥控鉛酸蓄電池發展概況

摘要：硅粉閥控鉛蓄電池與普通貧液式和膠體閥控鉛酸蓄電池不同。硅粉閥控鉛酸蓄電池是將顆粒二氧化硅緊密填充在極板之間的空間和極群組周圍，電解液保持在正極板、負極板、隔板和顆粒二氧化硅中。緊密填充的顆粒二氧化硅從各個方向對極板施加高的均勻壓力，抑制活物質和板柵的失效，從而提高了鉛酸蓄電池循環壽命。本文綜述硅粉閥控鉛酸蓄電池的發展概況。 敘詞：閥控鉛酸蓄電池 顆粒二氧化硅 Abstract：Granular silica valve-regulated lead-acid(VRLA)battery is different from conventional tarved-type and gelled-type batteries.In this battery,granular silica is tightly packed into the space between the plates and around the elements and the electrolyte is retained in the positive plates,the negative plates,the separators and the granular silica.The tightly packed granular silica applies high and uniform compresion to the plates from every directions,and it is expected to suppress the deterioration of the active material and grids and thus it will provide longer cycle life.Development outline of this battery was reviewed in this paper.
