Problems solved by technology

[0002] The defects of traction lead-acid batteries at home and abroad are constantly emerging, seriously affecting the use efficiency of customers and constraining the development of the company, mainly reflected in;
[0003] (1) The vulcanization of the negative electrode caused by high current charging and discharging will lead to the failure of the plate and directly affect the service life of the battery.
[0004] (2) The specific energy is low. The theoretical specific energy value of lead-acid batteries is 70w, h / kg, but in reality it can only reach 10-50w, h / kg. The main reason is that the volume of inactive substances is large, and the utilization of active substances rate is very low,
[0005] (3) The cycle life is low, which is mainly reflected in the sulfation of the negative electrode, elastic fatigue of the separator, corrosion of the positive plate,
[0007] (5) The charging acceptance ability is poor, the time is too long, and the power consumption is large
[0008] Lead-acid batteries and their excellent cost performance still occupy a dominant position in the battery field. Although the technology of valve-regulated batteries has become increasingly mature, they have problems such as short service life, inconsistent floating charge voltage, low reliability, and low specific energy. The development and deepening of new technologies and application fields in the battery field also bring great challenges to lead-acid batteries. Only with continuous improvement and innovation in technology can lead-acid batteries not be replaced by other chemical energy sources
