浅谈阀控式密封胶体电池技术(一)——胶体电池的定义探讨

Discussion on gel battery technologies of VRLA batteries

本文从阀控式铅酸电池的原理,阳光电池的发展过程,胶体电池的组成、结构和特性等方面探讨了胶体电池的内涵。胶体电池不是指电池内是否含有硅凝胶电解液,而是指采用富液式设计、微孔塑料隔板和用硅凝胶技术完全固定硫酸电解液的阀控式铅酸电池。

In this paper, the concept of the gel battery is discussed from the principle, the development history, the gel electrolyte composition, the structure and characteristics of the valve-regulated lead- acid （VRLA） batteries containing the gel electrolyte. For the gel electrolyte VRLA battery, not only the sulfuric acid electrolyte is fixed effectively in the battery, but also the flooded design and the microporous plastic separator are adopted. The gel battery differs from AGM （Absorptive Glass Mat） battery in the fixed way of sulfuric acid electrolyte for VRLA batteries, the concept of which has been accepted widely by the VRLA battery industry. In this article, we discussed the principle and fundamental concept of the gel battery from different perspectives in the hope of achieving a more clear and unified understanding for gel battery.
