Samsung believes that it will start mass production of its solid-state battery in 2026 possibly for the Galaxy Watch.
Samsung Electro-Mechanics is currently testing a new all-solid-state battery for wearable devices. Unlike the currently employed lithium-ion batteries, no liquid electrolytes are necessary with a solid-state battery which is, in fact, solid. The energy density of the solid-state battery, at 200Wh/L, not only tops the density of lithium-ion batteries, it also has the highest density in the industry. Samsung’s Electro-Mechanics unit has been working for three years on the solid-state battery and created a prototype that customers are currently testing.
The plan is to have the solid-state battery ready to start going through mass production in 2026. Designed for wearable devices, the solid-state battery could make its debut on the Galaxy Watch 9 in 2026.
