摘要

国际双极电力公司(Bipolar Power International, BPI)开发的铅酸电池技术是其10年双极铅酸电池研究工作的成果。这项工作为正负极板带来了新的浆料组合物，在循环过程中提供了更高的材料利用率和更好的容量维护。新型正极浆料是水基的，使用了预硫酸盐铅化合物，并添加了导电添加剂，提高了形成过程中的电荷效率。负极膏体也是水基膏体，使用预硫酸盐铅化合物，并具有改性膨胀剂以提高地层效率。描述了从双极功中得到的负、正活性质量的物质利用效率。在12V/26Ah电池的栅格型板上使用这种新浆料的初步实验表明，与相同的商用电池相比，性能有了显著提高。使用BPI浆料，VRLA制造工艺的简化和改进也成为可能。

Increasing material utilization of lead-acid batteries using BPI technology

The lead-acid battery technology developed at Bipolar Power International (BPI) is the outcome of its 10 years of research work in developing bipolar lead-acid batteries. This work has resulted in new paste compositions for both positive and negative plates, which provide higher material utilization and better capacity-maintenance during cycling. The new positive paste is water-based using a pre-sulfated lead compound, with a conductive additive which improves the charge efficiency during formation. The negative paste is also water-based paste, using a pre-sulfated lead compound, and has a modified expander to improve formation efficiency. The material utilization efficiencies of both negative and positive active mass as obtained from the bipolar work are described. An initial experiment using this new paste on grid-type plates in a 12V/26Ah battery has demonstrated significant performance improvement over an identical commercial battery. Simplification and improvement of VRLA manufacturing processes also appear possible using the BPI paste.
