Samsung SDI, a South Korean battery manufacturer, aims to achieve an energy density of 900 Wh/L with its solid-state batteries and plans to start mass production in 2027.
This is the first concrete statement from the company regarding mass production readiness. While Samsung SDI had started pilot production of solid-state cells a year ago, a timetable for mass production had not been announced until now.
The announcement only mentions the volumetric energy density and does not specify the weight-related energy density. Higher energy density can lead to longer range or smaller and cheaper batteries with the same range. Solid-state batteries are safer as they do not contain highly flammable liquid electrolytes.
Samsung SDI plans to utilize proprietary solid electrolyte and anode-less technologies to achieve the highest energy density in their solid-state battery product. In addition, Samsung SDI will showcase other battery technologies at the InterBattery 2024 event, including faster charging and ultra-long-life batteries, although these technologies are not expected to be ready for series production until 2026 and 2029, respectively.
