Problems solved by technology

Under such working conditions of traditional lead-acid batteries, coarse lead sulfate crystals that are easy to fall off are easily formed on the surface of the pole, which cannot be transformed into lead during the subsequent charging process, resulting in a decrease in the battery's charge acceptance and worsening the battery cycle. performance

Abstract

The invention relates to the field of power batteries, in particular to a high-efficiency battery for a new energy vehicle, comprising a shell, wherein the shell is a rectangular shell structure withan opening facing upward; A electrode plate group comprise a plurality of positive electrode plates and a plurality of negative electrode plate arranged alternately and overlapped to form an electrodeplate group; An end cap that closes the opening of the housing; The electrode comprises positive electrode pillars and negative electrode pillars arranged at both ends of the upper part of the end cap, wherein the positive electrode pillars and the negative electrode pillars pass through the end cap through respective through holes, extend into the shell, and are respectively connected with the corresponding positive electrode plates and the negative electrode plates through an electrical connection plate. The aim of the invention is to stabilize the lead paste by the way of the tubular electrode plate, so that the lead paste is not easy to fall off, the discharge efficiency is guaranteed, and the service life is prolonged.

Description

technical field [0001] The invention relates to the field of power batteries, in particular to a high-efficiency storage battery for new energy vehicles. Background technique [0002] With the continuous development of new energy storage and power markets, higher requirements are placed on the energy density, power density and cycle life of lead-acid batteries. Especially in hybrid vehicles and intermittent new energy storage applications, secondary batteries are required to have good charge acceptance and long cycle life under partial state of charge. Under such working conditions of traditional lead-acid batteries, coarse lead sulfate crystals that are easy to fall off are easily formed on the surface of the pole, which cannot be converted into lead during the subsequent charging process, resulting in a decrease in the battery's charge acceptance and worsening the battery cycle. performance. Contents of the invention [0003] The purpose of the present invention is to ...
