SEOUL -- South Korea's Samsung SDI said Wednesday that it will begin mass production of solid-state batteries for electric vehicles and other applications in 2027.
At the InterBattery trade show in Seoul, the Samsung Electronics group company outlined plans to begin producing high-performance solid-state batteries with an energy density of 900 watt-hours per liter -- a 40% improvement from its lithium-ion cells.
Solid-state batteries are widely considered the future of storage batteries. They have short charging times and high energy density, which can extend the range of EVs. They can also be made lighter and safer than lithium-ion batteries, which contain a flammable electrolyte solution.
Samsung SDI last year launched a pilot production line in Suwon, near Seoul, and is now working to improve the batteries there while honing mass-production capabilities to improve yield.
Also in 2023, the company established a team to promote the commercialization of its solid-state batteries, marketing the product mainly to existing clients like BMW. It started shipping sample batteries to leading global automakers earlier this year.
Samsung SDI will set its production plans for 2027, including how many batteries it makes and where, based on demand.
Other players are making inroads into the field as well. Hyundai Motor is advancing research and development with the goal of mass-producing solid-state batteries in 2027. Toyota Motor aims to start selling EVs equipped with solid-state batteries in 2027 or 2028.
