【 New Energy News】Zhongke Solid State Battery Project Landing

The Keguneng Sulfide All Solid Electrolyte Production Base Project has been signed in Liyang. Chen Liquan, academician of the CAE Member, attended the ceremony and delivered a speech via video. Chen Jinhu, secretary of the Municipal Party Committee, attended the ceremony and witnessed the signing of the contract.

All solid-state batteries are one of the main research and development directions for the next generation of power batteries. Sulfide all solid-state batteries have overwhelming advantages over liquid batteries in terms of long cycle life, wide operating temperature range, high safety, and high energy density. The core team of the project is composed of Wu Fan's scientist studio jointly founded by the Institute of Physics of the Chinese Academy of Sciences, the Yangtze River Delta Physical Research Center and the Tianmu Lake Advanced Energy Storage Technology Research Institute. It will build the world's first production line for large-scale preparation of sulfide solid electrolyte, providing sufficient practical experience and basic data for the future preparation of 10000 ton sulfide solid electrolyte The core key intellectual property rights that have achieved a world leading position in terms of process routes and other aspects.

The signing ceremony for the Zhongke Solid Energy Sulfide All Solid Electrolyte Production Base project was held in Changzhou City. Chen Liquan, an academician of the CAE Member, attended the ceremony and delivered a speech via video. Wu Fan, chairman of the board of directors of China Science and Technology Glenn, and leaders of Changzhou City attended the ceremony.

It is reported that the project will be carried out in two phases. The first phase has a total investment of 1 billion yuan for the large-scale production of all solid sulfide electrolyte materials. It is expected to have full production capacity from 2025 to 2026, and small-scale trials of sulfide solid electrolyte membranes, raw materials, and all solid battery cells will be launched in the same year. The total investment in the second phase is 5 billion yuan, and it is planned to build an all solid-state battery industry park before 2030. The supporting upstream and downstream industry chain will form a market of 100 billion yuan.

Zhongke Guneng is a "new force" in solid-state batteries

According to data, Zhongke Guneng, also known as Liyang Zhongke Guneng New Energy Technology Co., Ltd., was established on October 27, 2022 and has been in operation for less than a year.

The legal representative of Zhongke Guneng is Wu Fan, and its business scope includes the research and development of new materials; Battery manufacturing; Production of battery spare parts; Battery sales; Sales of battery spare parts, etc.

It is understood that the core team of Zhongke Guneng is composed of Wu Fan Scientists' Studio jointly founded by the Institute of Physics of the Chinese Academy of Sciences, the Yangtze River Delta Physical Research Center and the Tianmu Lake Advanced Energy Storage Technology Institute.

The Zhongke Solid Energy Sulfide Solid Electrolyte Production Base Project will build the world's first production line for large-scale preparation of sulfide solid electrolytes with a capacity of 100 tons, providing sufficient practical experience and basic data for the preparation of 10000 tons of sulfide solid electrolytes in the future. At the same time, it will obtain the core key intellectual property rights of leading positions in equipment design, process routes, and other aspects in the world.

Global competition for solid-state batteries

Solid state batteries not only have high safety and energy density, but also have excellent "high and low temperature" performance. They are regarded as the next generation of power batteries and are a strategic high ground for competition among countries.

Currently, countries and regions such as China, Japan, South Korea, and Europe and America have clear indicators, expectations, and national level plans for solid-state batteries.

At present, the solid-state battery industry is generally in the research and development and pilot stage, with China, Japan, and South Korea taking the lead in the field of solid-state battery development. European and American governments and multiple enterprises are hoping to change the existing power and energy storage battery landscape through solid-state batteries.

In terms of the implementation routes of all solid-state batteries, there are mainly three technical routes: polymer, oxide, and sulfide. Among them, sulfide solid electrolytes have become one of the most promising technical directions due to their highest lithium ion conductivity and good mechanical properties.

Different countries and regions have a clear bias and optimism towards the technological route of solid-state batteries. For example, Japan and South Korea continue to fully invest in the research and development of sulfide all solid-state batteries, with basically no oxide route; China is relatively unique and the only country in the world to choose a mixed solid-liquid electrolyte route composed of oxides and polymers.

Enterprises in Japan, South Korea, and the United States have already conducted research and development layouts. However, in order to truly achieve mass production and application, sulfide all solid-state batteries still face many key basic scientific issues and practical development challenges.
