What causes battery self-discharge

1. The reason for own planning, whether it is a lead-acid battery or a lithium battery, will have self-discharge. This is one of the characteristics of the product, which is caused by some changes in the positive and negative ions in the electrolyte during storage. Users need not worry too much about this. 2. Reasons for impure electrolytes Although each electric vehicle battery manufacturer uses lead-acid electrolyte solutions in the production of batteries, the concentration and purity of the electrolytes used are very different from each other. The battery electrolyte used by regular large-scale manufacturers like Xupai Battery is very pure, and basically does not contain other impurities. The self-discharge speed of the batteries they produce is very slow, or even lower than that of the batteries in the industry. Self-discharge uniform value, and some electric vehicle batteries produced by small manufacturers or informal manufacturers have too many impurities near the electrolyte, and their self-discharge speed is very fast. After a few days, the electricity that has just been charged will be used up. . 3. The battery itself presents problems or external factors. Anyone who knows about electric vehicle batteries understands that when the wires near the battery form a bridge with some external bodies, it is prone to relatively strong discharge, or accidentally remove the iron wire or copper. The wire is placed on the battery and the positive and negative poles are connected, which will cause the discharge.
