摘要
从原理上分析了纳米气相二氧化硅胶体铅酸蓄电池的特性,介绍了一种研究成果,应用于铅蓄电池的硅胶体的制造原理和方法。主要是利用表面化学的基本原理和电化学动力学催化的基本方法,应用纳米气相SiO2溶胶的半导体掺杂电化学界面催化理论和纳米气相二氧化硅的表面改性理论,对纳米气相二氧化硅的表面改性,应用湿法改性:用有机改性,填加偶联剂和高分子表面活性剂和分散剂,如萘黄酸甲醛缩合物、聚丙稀酸、乙二醇、丙稀酸等。用无机改性,填加硼、磷、锡、硒等元素的化合物,都能达到改性的目的。使铅酸蓄电池具有克服了三种早期容量损失达到长寿命、大容量等优良的特性。
Characteristics of silica gel lead-acid batteries are studied in this paper first. And then, we introduce a new method to manufacture the silica gel. That is utilizing semiconductor doping and electrochemical catalysis theory to modify the surfaces of the fumed nano silica particles. Surface modification have two type agents - organic and inorganic. Organic agent includes coupling agents, polymer surfactants and dispersants, such as Poly Acrylic, Ethylene Glycol, and Acrylic. Inorganic agent consists of compounds of Boron, Phosphor, Selenium and Lithium elements etc. The nano silica gel lead-acid batteries have overcome three early types of capacity loss, and thus can have a longer life and larger capacity.
