Establishment of battery production line by 2025
Manufacturing method using ‘composite electrolyte’ instead of sulfide
“Density of 400Wh per kg…safer than lithium batteries”, ‘[E-Daily reporter Yang Ji-yoon] Chinese automaker SAIC plans to establish a solid-state battery (ASB) production line by 2025. SAIC aims to release vehicles equipped with solid-state batteries starting from 2027.’,

, ‘According to reports from Chinese economic media Chains News and Yonhap News Agency on the 26th, SAIC announced its plans to produce solid-state batteries in collaboration with Chingtao (Kunsan) Energy Generation Co., Ltd., an organization in which they have invested.’,
,
, ‘Solid-state batteries, touted as the “dream battery” to replace the current mainstream lithium-ion batteries for automobiles, offer high energy density, stability, and long driving range.’,
,
, ‘The main challenge of solid-state batteries lies in the solid electrolyte. Currently, in the Chinese industry, there are various technical paths such as oxide, polymer, and sulfide electrolytes. Shanghai Automotive’s solid-state battery uses a “polymer-inorganic composite electrolyte” instead of the sulfide chosen by most companies, as reported by Chains News.’,
,
, ‘SAIC did not provide detailed information on the polymer-inorganic composite electrolyte materials. However, they claimed that the battery density of 400 watt-hours (Wh) per kilogram (kg) is superior in terms of stability and cost compared to liquid lithium batteries.’,
,
, ‘Currently, Toyota holds the most patents related to solid-state batteries. Toyota has set a goal to release vehicles equipped with solid-state batteries between 2027 and 2028, while Korean companies such as LG Energy Solution (373220), Samsung SDI (006400), and SK Innovation have plans to produce solid-state batteries between 2025 and 2028. In China, the world’s leading battery company, CATL, is set to produce small quantities of solid-state batteries in 2027.’,
