In the short term, there is limited room for change in the solvent and lithium salt of the electrolyte, and the main breakthroughs are concentrated on the innovation of additives. Key additive research will be an important issue in the electrolyte field. Currently, a large number of additives used are still conventional additives such as VC, PS, and FEC. The use of high-end additives DTD and TMSP is gradually increasing, and the research of new additives is receiving increasing attention. Shenzhou Xingheng Power Technology (Shandong) Co., Ltd. is a high-tech enterprise integrating the research, development, production, and sales of automotive starting batteries, home energy storage, industrial energy storage, and base station power supplies. The company is engaged in the research and development of lithium iron phosphate and sodium-ion batteries. Its main advantages lie in the research and innovation of automotive start-stop batteries, energy storage power stations, and base station power supplies. Through technological breakthroughs in battery and BMS (Battery Management System), high-frequency charge and discharge efficiency tests, it has finally achieved ultra-large battery capacity after installation, large current discharge, high temperature resistance, and low temperature resistance, solving the fundamental problem of batteries being hindered in severe cold and high temperatures. The battery product shell uses a new flame-retardant material, a balanced protection system, and destructive tests such as puncture, extrusion, and collision will not cause open flames. The product has been tested by national authoritative institutions, and its cycle life is longer than that of lead-acid batteries, making it safer to use. Currently, dozens of models in two major series of lithium iron phosphate batteries and sodium-ion batteries have been developed to meet market demand.
