Samsung is testing the world’s first small all-solid-state battery

The new batteries should be safer and much more durable.

Samsung Electro-Mechanics has created the world’s first ultra-small, all-solid-state battery for wearable devices.

The new battery is reported to have an energy density of 200Wh/L, which is the highest in the battery industry.

The company has spent more than three years developing the latest battery and created a prototype that customers are now testing.

If all goes well, Samsung Electro-Mechanics plans to release the battery to mass production in 2026. The company’s Galaxy Watch could be the first wearable to use it.

The same battery could also be used in other Samsung devices, such as a smart ring or earbuds.

Manufacturers are looking for a replacement for widely used lithium-ion batteries because all-solid-state batteries are made from solid materials and not liquid electrolytes.

Such batteries are safer as they don’t tend to overheat, have a longer lifespan, and have higher energy density. All-solid-state batteries can also be made in different shapes, which helps when manufacturing wearable devices.

In the span of three years, Samsung Electro-Mechanics has filed more than 40 patents related to oxide-based all-solid-state batteries.
