Samsung Electro-Mechanics appears to be making great strides in the solid-state battery segment. The company has reportedly developed the world's first ultra-small all-solid-state battery, and its new creation could power future Galaxy Watches and other wearables in 2026.
The Electro-Mechanics arm has reportedly developed an ultra-small solid-state battery prototype that is now under evaluation with input from its corporate customers.
Reports say this Samsung-made solid-state battery prototype has an energy density of 200Wh/L, with sources (via
Business Korea) claiming it is
“the highest in the battery industry.” That doesn't sound like a lot to qualify as the industry's highest, even compared to lithium-ion, so there might be an error in the reporting, or perhaps a different measuring methodology may have been used to reach that figure.
In any case, this ultra-small solid-state battery could power future Galaxy wearables, which is very exciting news, given the known qualities of this technology. Solid-state batteries are safer and can store a lot more energy than lithium-ion solutions, which could change the game for future Samsung smartwatches and other wearables.
Galaxy Watch 9 may have a solid-state battery
The recent report mentions that if the new ultra-small solid-state battery passes the ongoing testing period with flying colors, Samsung Electro-Mechanics will want to start mass manufacturing it in the first half of 2026.
Furthermore, Samsung's mobile division could become a big client for this new solid-state battery developed by Electro-Mechanics, and the future Galaxy Watch 9 series might be among the first Samsung wearables to use it, along with the 2026 Galaxy Buds and
Galaxy Ring.

Samsung Electro-Mechanics has been working on solid-state batteries for years, and the company has amassed more than a dozen patents from KIPO.
Last year, Samsung Electro-Mechanics
told shareholders it was preparing
“small all-solid-state batteries for green energy.” President Chang Duckhyun added he would
“Take a separate time to explain when I'm at the point of making a prototype.”
In light of this recent news, it sounds like that prototype now exists and is being tested by potential customers, including Samsung's mobile division.
