From November 1-3, 2024, the 9th National Solid-State Battery Symposium was held at the Shangri-La Hotel in Xiamen, China. The conference, themed “The Current Status and Development of Solid-State Battery Technology”, gathered experts, scholars, and representatives from renowned companies and research institutions in the solid-state battery field. The event provided a platform for in-depth discussions on core technologies and key scientific issues, aiming to effectively drive breakthroughs in solid-state battery technology and its applications.
Solid-state batteries, as an advanced technology in the field of power batteries, have attracted significant attention in recent years due to their advantages in high safety and potential for high energy density. They are expected to become the next-generation power solution for electric vehicles (EVs) and other mobile devices.
During the keynote speech sessions, prominent figures from industry leaders such as FAW, CATL (Contemporary Amperex Technology Co., Ltd.), Gotion High-Tech, Weilan, Qingtao, as well as experts from Tsinghua University, Chinese Academy of Sciences, Shanghai Jiao Tong University, and Northeast Normal University, discussed the core technologies and key scientific challenges in the solid-state battery field. They shared their latest research achievements and insights on areas such as solid-state battery materials, processes, performance testing, and commercialization applications.
Dr. Xie Haiming, Chairman of Dongchi Energy, was invited as a special guest to deliver a report titled “Solid-State Battery Research and Commercialization”. In his presentation, Dr. Xie shared the journey of Dongchi Energy’s development of high-safety, high-energy polymer-based solid-state batteries. He also highlighted the company’s scientific breakthroughs and successful transition from research to commercialization over the past twenty years. Dongchi Energy has established a 0.5 GWh solid-state battery industrialization base and, in 2024, formed a joint venture with Wenzhou Guansheng Co., Ltd. to invest in a semi-solid battery production line. Dongchi Energy’s semi-solid iron lithium batteries are known for their extreme safety and long cycle life, and they are being mass-produced for use in industrial and commercial energy storage, electric boats, and heavy-duty trucks. Additionally, Dongchi Energy's lithium-metal-based polymer quasi-solid-state batteries offer high energy density (420-500 Wh/kg) and high safety. These batteries are poised for large-scale industrialization this year and are already being used in drones, electric cars, and other applications.
New energy has become a major focus in the industry, with electric vehicles relying on power batteries and green electricity (such as wind and solar) depending on energy storage batteries. Within the trillion-dollar markets of power batteries and energy storage batteries, lithium-ion batteries dominate. However, traditional liquid lithium batteries are prone to flammability, explosions, and low energy density, leading to concerns about range anxiety and low-temperature performance. There is an urgent need to develop high-energy, high-safety power batteries. At the symposium, Dongchi Energy showcased its semi-solid lithium iron phosphate (LiFePO4) and quasi-solid-state ternary lithium batteries, both known for their high safety and high energy density. These products are widely used in home energy storage, industrial and commercial storage, as well as large-scale energy storage systems for wind energy, solar energy, and more. Additionally, these batteries have applications in passenger vehicles, commercial vehicles, specialty vehicles, electric trucks, electric boats, and drones.
