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

The invention relates to a lead-acid storage battery, which comprises a casing, a first separator and a second separator are arranged inside the casing, the casing includes a casing surface and a bottom surface, and the casing surface includes a first side and a second The side surface is characterized in that the first partition is provided with a first groove, the second partition is provided with a second groove, the first groove and the second groove are communicated, and the bottom surface of the housing A third groove and a fourth groove are provided, the third groove and the fourth groove communicate with the first groove and the second groove respectively, the first side forms a fifth groove, and the second side forms a sixth groove, The fifth groove and the sixth groove communicate with the third groove and the fourth groove respectively, and the fifth groove and the sixth groove are respectively formed with first openings on the first side and the second side and a second opening. The invention ensures that the internal temperature difference of the battery is reduced during the formation process of the battery and ensures the consistency of the performance of the battery.
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. When the temperature exceeds 60 degrees Celsius, 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 t...
