Abstract

The invention discloses a battery plate for improving the active material utilization. The battery plate comprises a plate grid belt and a lead plaster. The plate grid belt comprises a metal plate belt layer and a lead cladding layer or a lead alloy cladding layer coated on a surface of the metal plate belt layer; the lead plaster is coated on an outer surface of the lead cladding layer or the alloy cladding layer. According to the battery plate for improving the active material utilization provided by the invention, through utilizing the metal plate belt layer containing high-conductivity metal, the proportion of the weight of a plate grid in active materials can be effectively reduced, and the weight of a battery is reduced. Metals such as copper, aluminum and titanium or an alloy material of the metals are adopted as a plate grid matrix, so that the electric conductivity of the plate grid can be effectively improved; the lead layer or the lead alloy layer is cladded onto the metal belt layer, so that firstly, an adhesive force of the lead plaster on the plate grid can be improved, and secondly, other metals can be prevented from contacting acid to produce redox reaction so as toinfluence a battery capacity.

Description

technical field [0001] The invention belongs to the technical field of lead-acid battery manufacture, and in particular relates to a battery pole plate which improves the utilization rate of active materials. Background technique [0002] Lead-acid batteries have a wide range of uses, and currently lead-acid batteries occupy a dominant position both in terms of output and application fields. It has a series of advantages such as high cost performance, high safety reliability and recyclability. However, with the advancement of science and technology, the low utilization rate of active materials in lead-acid batteries and the large proportion of the weight of the grid affect the overall utilization of the battery. The use of lead alloys and grids limits the improvement of the energy density of lead-acid batteries. In addition, batteries using lead alloy plates often have increased internal resistance, reduced capacity, and end-of-life due to electrolyte immersion corrosion. ...
