Valve control lead-acid storage battery anode material

Abstract

The invention discloses a battery plate electrode valve control lead-acid storage battery anode material possessing good homogeneity and high active matter usage rate. The lead cream for coating the plate electrode is composed of the material at the following weight percent (using the total weight of lead cream as reference), PTFE 6% / water miscible liquid 0.1% - 0.5%, vinyl cyanide staple fiber 0.08 - 0.5%, water 5 - 15%, 1.4g / cm the power of 3 H2SO4 solution 5 - 15%, Pb3O4 or lead powder 0 -30%, the residual is PbCO3.The invention can be used as the lead-acid storage battery anode coating film material.

Description

Technical field [0001] The invention relates to a material for forming a plate of a lead-acid battery, particularly a material for an active coating layer on the surface of a positive plate. Background technique [0002] Lead-acid batteries are widely used in backup batteries, energy reserves, and power sources. The positive electrode active material, which is the heart of lead-acid batteries, was first converted from two lead plates as electrodes and repeatedly charged and discharged. It can be said that the positive electrode active material was pure lead at that time. In the traditional lead-acid battery production process, the lead pollution caused by the pure lead used and the active lead oxide powder made from it as the electrode material not only damages the environment, but also seriously endangers the health of the production workers. In addition, the use of lead powder as the initial material of the positive electrode active material still has the...
