Lead-carbon winding battery for starting and stopping automobiles

Abstract

The invention discloses a lead-carbon wound storage battery for starting and stopping automobiles, belonging to the technical field of lead-acid storage batteries. The battery casing adopts a drum structure, and the casing material is made of modified PP, which is made of polyphenylene ether PPO high-temperature resistant material. The pole group adopts a winding structure, and the assembly pressure is 50-60kpa. ~2% K2SO4, add special carbon materials (activated carbon 0.2%~3.5%, conductive carbon black 0.2%~2.5%, indium oxide 0.01%~1%, lignin 0.1%~3%, humic acid 0.1% %~0.3%, barium sulfate 0.2%~2%). The invention improves the charge acceptance capacity of the battery, high-temperature-resistant cycle life, and the start-stop cycle life is greater than 100,000 times, solves the problems of poor high-temperature resistance and short start-stop cycle life of the existing flat-panel batteries, and is suitable for start-stop cycles in the automotive industry Batteries for cars.

Description

technical field [0001] The invention belongs to the technical field of lead-acid storage batteries, in particular to a lead-carbon wound storage battery for starting and stopping automobiles. Background technique [0002] With the rapid economic growth, energy shortages, environmental pollution and other issues have become major challenges for countries all over the world to achieve sustainable development, and the situation of energy conservation and emission reduction is still very severe. The automobile industry is my country's basic industry. In recent years, my country's automobile industry has developed rapidly, and the total production and sales volume has continued to grow. In 2013, the sales volume of automobiles exceeded 20 million, and the number of vehicles in stock exceeded 100 million. Therefore, accelerating energy conservation and emission reduction in the automobile industry has become the top priority of my country's energy conservation and emission reducti...

Problems solved by technology

[0005] However, the traditional automotive flooded battery can no longer meet the requirements of the start-stop system of the car, which will lead to problems such as short battery life, less start-stop times, and severe power loss. Moreover, there is a flat AGM start-stop battery developed by other battery manufacturers. It has not completely solved the cycle performance at high temperature and the short life of start-stop, so the use effect is not ideal, so it is very necessary to develop a new type of start-stop battery
