Problems solved by technology

Due to the structural problems of the battery, the temperature of the entire battery varies greatly. The temperature of the cells connected to each other is relatively high, and the temperature of the cells on both sides and the middle cell differs greatly. The acid density is inconsistent, resulting in poor consistency of the battery

Abstract

The invention relates to a lead-acid storage battery, which comprises a shell, wherein a first partition plate and a second partition plate are arranged in the shell; the shell comprises a surface and a bottom surface of the shell; the surface of the shell comprises a first side surface and a second side surface; the lead-acid storage battery is characterized in that a first slot is arranged in the first partition plate; a second slot is arranged in the second partition plate; the first slot communicates with the second slot; a third slot and a fourth slot are arranged in the bottom surface of the shell; the third slot and the fourth slot communicate with the first slot and the second slot respectively; a fifth slot is formed in the first side surface; a sixth slot is formed in the second side surface; the fifth slot and the sixth slot communicate with the third slot and the fourth slot respectively; and a first opening and a second opening are formed in the fifth slot and the sixth slot in the first side surface and the second side surface respectively. By the lead-acid storage battery, reduction of an internal temperature difference of the battery in the battery formation process is ensured and the consistency of the battery performance is ensured.

Description

technical field [0001] The invention relates to the field of lead-acid batteries. Background technique [0002] In view of the proven high performance, low cost, easy recycling and reliable safety of lead-acid batteries, it has been widely used in the world. Lead-acid batteries will generate a lot of heat during the internal formation process, which will As a result, the internal temperature of the battery is very high. If the temperature exceeds 60 degrees, the decomposition and precipitation of additives will occur, which will affect the low temperature, high current performance and service life of the battery. Especially in summer, the temperature of the battery will not drop. At present, the most commonly used and economical cooling method is to use circulating water for cooling. Due to the structural problems of the battery, the temperature of the entire battery varies greatly. The temperature of the cells connected to each other is relatively high, and the temperature...
