red star capital bureau reported on september 23rd that today, red star capital bureau learned from dongfeng motor that at the dongfeng motor brand autumn conference and the 9th science and technology innovation week, dongfeng motor group deputy general manager you zheng revealed that dongfeng is about to mass-produce solid-state battery products with an energy density of 350wh/kg, and will accelerate the self-development of the next generation of all-solid-state batteries with an energy density exceeding 550wh/kg.
according to the official website of the labor union of dongfeng motor group co., ltd., in 2018, dongfeng took solid-state batteries as an important strategic development direction and officially launched the project; in 2019, the development of the first-generation solid-state battery system was completed; in 2020, the first-generation solid-state battery was carried on the whole vehicle for off-line testing; in 2022, the first batch of dongfeng solid-state battery demonstration operation vehicles were officially delivered; in 2023, the second-generation solid-state battery has been developed. from august 31 to september 2, dongfeng displayed a new generation of solid-state battery exhibits at the 2024 world power battery conference. the solid-state battery system is equipped with high-energy-density solid-state cells, and the system energy density is as high as 285wh/kg. the official website of the labor union shows that dongfeng mentioned at the time that the company has successively mastered core technologies such as electrolytes, diaphragms, and in-situ curing, forming 240wh/kg and 350wh/kg solid-state battery products.
since the beginning of this year, my country's solid-state battery industrialization process has ushered in a "small climax". power battery companies such as catl (300750.sz), nio (09866.hk/nio.us), saic zhiji, ganfeng lithium (002460.sz), gac group (601238.sh), and xinwangda (300207.sz) have successively released new solid-state battery products.
according to the national business daily, at the 2024 teda automotive forum held on august 31, ouyang minggao, an academician of the chinese academy of sciences and a professor at tsinghua university, stated that from the perspective of technology research and development nodes, from 2025 to 2030, the all-solid-state battery industry will focus on solid-state electrolytes; from 2030 to 2035, the focus will be on high-capacity composite negative electrodes; from 2035 to 2040, the focus will be on high-capacity composite positive electrodes.
according to a research report by citic securities, solid-state batteries are expected to usher in a new round of electrification innovation cycle due to their high safety and high energy density. since 2024, my country's solid-state battery industry has seen marginal changes such as the launch of semi-solid mass-produced models and the penetration rate of semi-solid batteries in vehicles reaching 1%, signaling the arrival of industrialization. in 2030, the global solid-state battery market is expected to reach 1.2 trillion yuan.
