Samsung Galaxy Watch to use EV-like all-solid-state battery in 2026

Samsung could debut its first all-solid-state battery smartwatch in 2026. The company has recently announced the completion of small-sized all-solid-state battery development. It is expected to debut with a Galaxy Watch in 2026.

On September 22, Samsung Electro-Mechanics announced that it had successfully developed the world’s first small-sized all-solid-state battery. The company aims to commence the mass production of its new solution in 2026.

As compared to Li-ion batteries, all-solid-state batteries offer enhanced safety and greater flexibility in terms of shape. The company reportedly sent prototypes to its consumers for testing before production approval.

The next-gen all-solid-state battery features an industry-leading energy density of 200Wh/L. It can also be manufactured in curved shapes, making it ideal for smartwatches. Safety is also increased thanks to the non-flammable solid electrolyte.

Chosun expects the 2026 Galaxy Ring and Galaxy Watch could be the first set of devices to use the new battery technology. Samsung Elec won’t make any decision in a hurry as such a major change would be dangerous if not tested rigorously.

Samsung Electro-Mechanics explained that the battery is produced by stacking thin layers of electrodes and electrolyte materials, similar to the MLCC (multilayer ceramic capacitor) manufacturing technology it already possesses.
