Problems solved by technology

The traditional AGM battery has the characteristics of long life and strong starting ability, but when it is used to start and stop the car, it is in a partial charge state for a long time, the negative plate is very prone to sulfation, and the charging acceptance performance, especially the dynamic charging acceptance performance is poor. , the life of the battery is terminated due to charging difficulties, and it is difficult to meet the requirements of starting and stopping
Although the performance of the lead-acid battery is improved if a higher content of carbon material is added, such as increasing the conductivity, making the distribution of lead sulfate uniform, increasing the specific surface area, reducing polarization, and increasing the capacitance, etc., there are also some adverse effects, such as It is pointed out that directly adding a large amount of carbon to the negative lead paste will easily cause the lead paste to fall off during the cycle and reduce the life of the battery; at the same time, it also has the disadvantage of low high temperature resistance, which seriously affects the performance of lead-acid batteries in supporting products. Normal use
[0004] In view of the above drawbacks, although many start-stop batteries such as colloids have appeared in recent years, this type of colloidal electrolyte has slightly better overall performance than batteries made of sulfuric acid solutions, but the common problems are fast capacity decay, low specific energy, thermal runaway, and charging. Excessive acid mist, difficulty in starting at low temperature and other deficiencies make it difficult to solve the problem of parking requirements and meet the needs of the market and industry. At the same time, it cannot meet the requirements of energy saving and emission reduction and the promotion of clean production by the Ministry of Environmental Protection.
