At present, SAIC has set up a joint laboratory with solid-state battery specialist ChingTao Energy Development to develop batteries.
The stated goal of SAIC is to provide a range of over 1,000 kilometers with the new batteries in accordance with Chinese standards. If, at the same time, the required installation space in vehicles is not to be increased, a higher energy density will be required.
SAIC and ChingTao have released some key data about the planned solid state batteries, such as target range and 4C fast charging capability. However, the partners do not provide any information about the type of solid state technology - not everything that is described as a solid state battery actually provides the expected cost benefits. Based on the target range, it can be assumed that companies want to increase energy density, as well as improve safety and service life.
Details about the SAIC model, in which the first solid elements should be installed as early as next year, are also unknown.
ChingTao recently started construction of a solid state battery plant in Kunshan in China's eastern Jiangsu province, which will be designed for 10 GWh annual capacity. This is the second plant of the company - since 2020, ChingTao has a line for the production of solid-state lithium batteries with an annual capacity of 1 GWh.
