At the CES show held on January 13, 2025, Samsung Electro-Mechanics officially unveiled its newly developed prototype of a small solid-state battery with an energy density of 200 Wh/L, which is scheduled to be fully rolled out in 2026. This development marks a critical step in moving solid-state battery technology from laboratory research and development to large-scale adoption. As an emerging energy storage technology, solid-state batteries are regarded as potential alternatives to traditional lithium batteries due to their high energy density, strong safety and flexible structural design. Samsung Electro-Mechanics not only demonstrates its technological prowess, but also provides a new solution for improving the performance of future electronic devices.
Technical analysis: the core advantages of solid-state batteries
Samsung Electro-Mechanics' solid-state batteries use oxide-based solid electrolyte materials with excellent electrochemical performance and high stability. Compared to traditional lithium-ion batteries, these batteries eliminate the need for flammable liquid electrolytes and significantly improve safety, especially in extreme heat or mechanical shock environments, significantly reducing the risk of fire and explosion. In addition, solid-state batteries are designed to be more compact, achieving volumetric energy densities of up to 200 Wh/L by reducing the space between components, which is comparable to the level of today's mainstream lithium batteries.
Samsung Electro-Mechanics has adopted an ultra-compact design that further integrates battery components to improve energy storage efficiency. This design is particularly suitable for small devices with critical size and weight requirements, and can effectively extend their battery life. At the same time, the solid-state electrolyte has a longer cycle life, further enhancing the economy and practicality of the battery.
