How can we reduce the cost of power lithium batteries?

Improve the performance of the four major materials and indirectly reduce costs. Guangzhou Penghui Energy Technology Co., Ltd. has carried out technological innovations in terms of positive electrode, negative electrode, electrolyte, separator, etc., by improving the high and low temperature performance of the battery, to reduce the investment in the heating and cooling parts of the PACK , Thereby reducing the cost of power lithium battery PACK. According to Liu Jiansheng, Dean of Penghui Energy Research Institute, Penghui Energy overcomes the shortcomings of high nickel materials, inhibits the high voltage of high nickel from catalyzing the decomposition of electrolyte, and improves the stability of high nickel cathode materials; it is controlled by the development of silicon-carbon alloys. Anode material production cost; adopts electrolyte that is compatible with new anode and cathode materials, but also has the characteristics of high voltage and flame retardant; by reducing the thickness of the diaphragm, increasing the strength of the diaphragm, and improving the high temperature resistance and pressure resistance, etc. Innovation, effectively improve the safety performance of the battery. Starting from the four major materials, the safety performance of the battery itself is improved, and the corresponding input of PACK is reduced, so as to achieve the purpose of reducing the cost of the power lithium battery system. Reducing the price of auxiliary materials and external cost reduction. In the components of lithium-ion batteries, the shell material is not as concerned as the four major materials, but it plays a vital role in the safety performance and consistency of power lithium batteries, even in Cost reduction can also help the company. Compared with traditional steel, the cost of battery steel is relatively higher, and the production process is more stringent. From the initial steelmaking to the final production and packaging, there are extremely strict process controls. This results in the price change of battery steel shells being much higher than the price fluctuation range of raw steel. Dongshi Chuangzhan is a battery shell material supplier. The company takes the customer iron material cost control center as its service concept, and has long-term cooperation with Nippon Steel to introduce advanced materials, manufacturing technologies and processes to help customers improve the quality of battery shells. . During the price increase of battery steel shell materials, Dongshi Chuangzhan actively used the use of reservoirs and adjusted the procurement plan to prevent turbulent market such as skyrocketing and falling prices from affecting battery company production. In addition, for soft-pack batteries, promoting the localization of aluminum-plastic film has a positive meaning in reducing the cost of soft-pack batteries. It is predicted that the domestic aluminum-plastic film will only cost 70% of the imported aluminum-plastic film when the overall performance is the same as that of the imported aluminum-plastic film. Therefore, the realization of the localization of the aluminum-plastic film will undoubtedly reduce the production companies of soft pack batteries. Production costs. Increase production technology and technology to reduce costs Fang Jin, vice president of BAK Battery, said that on the one hand, BAK Battery reduces unit manufacturing costs through large-scale production, and on the other hand, it guarantees its core competitiveness through continuous technological innovation. In the view of BAK Battery, the vigorous development of the battery industry is both an opportunity and a hidden crisis. Battery companies are facing both the pressure of cost reduction and the pressure of industry integration. Intelligent battery production has become an irreversible trend. Under such an industry background, BAK Battery has implemented smart manufacturing projects to increase the company's output, reduce production costs, and improve battery quality and production delivery capabilities. In April of this year, Battery China.com learned during a survey of BAK Battery that BAK Battery’s intelligent manufacturing line includes fully automated hardware equipment and highly intelligent software systems, namely: vertical integration from the workshop to the management level. Adaptive equipment, customized products through the integration of e-commerce and production, visualization, traceability, quality control, electronic billboards/automatic replenishment, preventive maintenance, preventive quality control. At present, the production of BAK batteries has been fully automated. Starting from intelligent manufacturing, it has achieved cost reduction control in five dimensions. BAK battery is just a microcosm of the cost reduction of intelligent manufacturing of lithium battery company. Xie Hui, a special researcher of Mingguan New Materials Co., Ltd., introduced the cost reduction solution of Mingguan New Materials. Xie Hui said that increasing the product qualification rate is an important way to reduce production costs. For soft-pack batteries, the appearance of external scratches and electrolyte contamination has a greater impact on the battery qualification rate. Mingguan New Materials reduces or eliminates poor appearance from three aspects: first, to train and optimize front-line personnel in operation to improve the overall quality of operators; second, to increase the proportion of equipment intelligence, improve equipment operation accuracy, and improve equipment The contact surface with the battery is softened to reduce the friction on the surface and reduce the secondary operation of the battery; third, improve the performance of the aluminum-plastic film, compound a layer of PET on the surface of the aluminum-plastic film, PET is corrosion-resistant, impact-resistant, and water-resistant And excellent protection performance, using it as the surface structure of the aluminum-plastic film can prevent electrolyte pollution and increase the product qualification rate.
