With the increasing global attention to environmental protection and the adjustment of energy structure, new energy vehicles have become the mainstream direction of future automobile industry development with their advantages of zero emissions and low energy consumption. In the development process of new energy vehicles, power batteries play a very important role. As the core component of new energy vehicles, their performance directly determines key indicators such as the range, safety, reliability and cost of new energy vehicles.

According to data from the China Passenger Car Association, from January to August this year, China's auto industry sold a total of 6.016 million new energy vehicles, a year-on-year increase of 35.3%. In August, the penetration rate of new energy vehicles exceeded 50% for the second consecutive month, reaching 53.9%. During the same period, according to data from the power battery industry, from January to August this year, my country's cumulative installed capacity of power batteries was 292.1GWh, a cumulative year-on-year increase of 33.2%.

It can be said that the technical level and development status of power batteries will greatly affect the future direction of the new energy vehicle industry. As Shi Jianhua said in his speech, power battery technology is like the heart of electric vehicles, providing vehicles with a continuous source of development "power". The "high" and "low" quality of an electric vehicle is inseparable from the technology of power batteries. In his view, power batteries are the core technology of electric vehicles. Only by making good batteries can we make good electric vehicles and lead the automotive industry towards a greener and smarter future. This is not only a responsibility to consumers, but also a responsibility to the future of the entire electric vehicle industry.

It is true that the rapid rise of new energy vehicles has indeed opened up a very broad space for the development of power batteries. However, we must clearly realize that the development of power batteries is not a one-day job, nor is it something that can be achieved overnight. It requires a large amount of capital investment, the wisdom of countless scientific researchers, and long-term practical exploration.

In this process, we cannot just pursue speed, but also pay attention to quality and sustainability. Moreover, in the process of developing power batteries, we must pay attention to methods and approaches, and we cannot blindly follow the trend or rush for quick success. We must deeply study market demand and technological trends and formulate scientific and reasonable development strategies. We must proceed on the basis of conforming to the trend of the times and respecting the objective facts of industrial development, and fully consider various factors such as environmental protection, sustainable use of energy, and social and economic development. Only in this way can we ensure the healthy and stable development of the power battery industry and lay a solid foundation for the future of new energy vehicles.

From the perspective of industrial development, the progress of power batteries is related to the future direction of new energy vehicles, and its technological innovation and quality improvement are crucial; on the other hand, the sustainable development of power batteries needs to take into account multiple factors such as the environment, energy and economy. This process is full of challenges but of great significance. At this forum, several experts from different fields of production, academia and research also deeply analyzed the current status and problems of power battery development, and put forward forward-looking and constructive insights, providing multiple perspectives and innovative ideas for the future development of the power battery industry.

In the theme sharing of "The Past and Future of Automotive Power Batteries", Academician Jin Yong gave a detailed introduction to the development history of power batteries, and pointed out that lithium batteries have always been an important carrier of electrical energy storage. In the automotive industry, the rapid development of electric vehicles has promoted the technological innovation of lithium batteries. In his opinion, in order to promote the continuous innovation of lithium batteries, it is necessary to attach importance to material innovation and structural innovation from the underlying logic. Therefore, the future development direction of power batteries includes improving specific energy density, such as developing solid lithium batteries, using solid electrolytes, solving safety problems, increasing specific energy density, and developing from polymer electrolytes to oxide semi-solid batteries, sulfide and halide all-solid lithium batteries. At the same time, sodium-ion batteries, as a new idea, have the advantages of low price and wide operating temperature, but low specific capacity density, and cannot completely replace lithium batteries at present.

Just as Geely's Shield Short Blade battery has demonstrated outstanding results in structural innovation, these innovative measures have provided an excellent example for the structural optimization of lithium batteries. They also prove that only by deeply exploring the innovative paths of materials and structures from the underlying logic can we continuously tap the huge development potential of lithium batteries and open up their broad market space.

In the theme sharing of "Technological Innovation and Application Challenges of Automotive Power Batteries", Engineer Wang Fang started from the technical route of power battery development and interpreted the cost, life, safety and other aspects of the current ternary lithium and lithium iron phosphate batteries. Wang Fang pointed out that with the rapid development of new energy vehicles, consumers' demand for endurance, energy replenishment, safety and recycling has promoted the technological innovation of power batteries. In terms of material and structural innovation, structural innovations such as short knife batteries and solid-state attempts in system innovation have not only improved energy density, but also improved safety to a certain extent. The results of thermal diffusion tests show that more and more batteries can be tested without catching fire, proving the continuous improvement of China's battery safety. At the same time, Wang Fang also mentioned that safety is the most important indicator of lithium batteries, and short knife batteries are a new generation of high-safety lithium iron phosphate batteries.

It can be said that safety is the core key of power batteries and an important guarantee for the stable operation of new energy vehicles. In the theme sharing of "New Momentum of Power Batteries - More Efficient and Safer", Professor Xiong Shusheng also emphasized the importance of safety and efficiency to the development of power batteries. He said that safety is the core label of lithium iron phosphate batteries, and high efficiency is the icing on the cake for batteries. For example, Geely's short-blade shield battery has high safety performance, high mileage, cold resistance and fast charging speed. The two major propellers of power batteries are safety and efficiency. Only by adhering to more efficient and safer development standards for a long time can we promote the advancement of battery technology.

Indeed, in the development history of power batteries, safety has always been the cornerstone. Without safety guarantees, all performance advantages are out of the question. Efficiency is the goal that power batteries are constantly pursuing. Higher energy conversion efficiency, faster charging speed, and longer driving range are all key factors in promoting the popularization and development of electric vehicles.
