SAIC (Shanghai Automotive Industry Corporation) is engaged in solid-state battery development. According to local news outlets and reports from CN EV, SAIC plans to release its first electric vehicle (EV) equipped with solid-state batteries from its assembly lines in China within the next two years, around 2025. However, details about the solid-state battery model and its features are unknown.
SAIC established a joint laboratory with solid-state battery specialist ChingTao Energy last year. Initially, the aim was to incorporate solid-state batteries into one of SAIC’s electric models as early as 2023. The company’s goal was to achieve a range of over 1,000 kilometres, based on Chinese standards, with the new batteries.
SAIC and ChingTao shared some essential information about the planned solid-state batteries, such as targeting a range of over 1,000 kilometres and a 4C fast-charging capability. The “C” refers to the battery’s charging multiplier, and 4C indicates the theoretical possibility of fully charging the battery within 15 minutes.
However, more information is still needed regarding the specific type of solid-state technology being developed. It should be noted that not all solid-state batteries offer the anticipated cost advantages. Given the range target, it can be assumed that SAIC and ChingTao aim to increase energy density while improving safety and service life.
According to SAIC’s statement, the joint laboratory between SAIC and ChingTao is focused on developing solid-state battery integration technology to accelerate mass production.
ChingTao Energy began constructing a solid-state battery plant in March 2022 in Jiangsu, an eastern province of China. This facility is designed to have an annual capacity of 10 GWh. It represents the company’s second factory, with a battery production line has already been operational since 2020, capable of producing 1 GWh per year.
It’s worth noting that SAIC is not limited to operations in China. The company has a presence in Europe and the UK through its Maxus electric vans and the MG brand.
