Description

Screening glass for storage battery and storage battery

Technical Field

The utility model relates to a battery field especially relates to a screening glass and battery for battery.

Background

During the use of the lead-acid battery, substances falling off from the plates are transferred from the plates to other parts in the battery along with the flow of the electrolyte. When some material lands on top of the negative plate, spongy lead velvet may be generated, which cumulatively grows to some extent to connect the top of the negative plate to the positive bus bar above it, or to its adjacent positive plate, thereby causing a short circuit inside the battery. Many flooded lead acid batteries are equipped with a protective plate on top of the cluster to prevent shorting by the lead wool growing on top. Some protection plates have tooth-shaped structures and extend into the bottoms of the positive and negative bus bars, and some protection plates do not have the tooth-shaped structures extending into the bottoms of the bus bars. Some protective plates have a sheet-like structure with holes. The holes prevent gas from collecting under the protective plate and also improve the flow of electrolyte. But the distribution of specific holes has no correspondence with the protected cluster structure. This results in unsatisfactory protective effect. When holes are located above a negative plate, there is still the possibility of lead velvet growing from the negative electrode to the positive busbar or adjacent positive plate. The utility model provides a protection shield corresponds the distribution in hole and the cluster structure under the protection shield to the risk of lead fine hair short circuit has further been reduced.
