SAIC, a prominent automotive company, is making strides in the development of solid-state batteries, as it aims to introduce its first series electric vehicle (EV) equipped with this new technology in China within the next two years. Local news outlets have reported on SAIC’s announcement made during an investor survey, revealing their plans to launch a solid-state battery model by 2025, although specific details remain undisclosed at this time.
In pursuit of this innovative venture, SAIC had established a joint laboratory in collaboration with solid-state battery specialist ChingTao Energy last year. The initial objective of this partnership was to incorporate solid-state batteries into one of SAIC’s electric models as early as 2023. During this period, SAIC’s ambitious target was to achieve a range exceeding 1,000 kilometers, in accordance with Chinese standards, leveraging the capabilities offered by solid-state battery technology.
SAIC and ChingTao have shared certain key specifications regarding their anticipated solid-state batteries, including the targeted range and a 4C fast-charging capability. The term “C” refers to the battery’s charging multiplier, and with a rating of 4C, it suggests that the battery could potentially be fully charged within a mere fifteen minutes.
However, pertinent information regarding the specific type of solid-state technology being employed remains undisclosed. It is worth noting that not all batteries labeled as “solid-state” provide the anticipated benefits in terms of cost-efficiency. Given the range objective, it can be inferred that SAIC and ChingTao are focusing on enhancing energy density, as well as improving safety and overall lifespan.
SAIC has also stated that the joint laboratory will be devoted to developing integration technology for solid-state batteries, with the aim of accelerating mass production. This will be crucial in ensuring the feasibility and scalability of implementing this advanced battery technology in their future electric vehicles.
ChingTao has taken significant steps towards solid-state battery production, commencing the construction of a dedicated plant in March 2022, located in the eastern Chinese province of Jiangsu. The facility is designed to have an annual production capacity of 10 GWh, marking ChingTao’s second factory after its battery production line, which has been operational since 2020 and boasts an annual capacity of 1 GWh.
While SAIC’s endeavors extend beyond China, with a notable presence in Europe and the UK through their Maxus electric vans and MG brand, their commitment to solid-state battery research and development signifies their dedication to advancing the future of electric mobility. As the company progresses towards their target of introducing a solid-state battery electric vehicle in 2025, automotive enthusiasts and industry experts eagerly await further details and breakthroughs in this cutting-edge technology.
