Samsung Unveils World’s First Miniature Solid-State Battery for Wearable Devices

Samsung has made a groundbreaking leap in wearable technology by unveiling the world’s first small-sized solid-state battery, designed specifically for wearables. Developed by Samsung Electro-Mechanics after three years of intensive research, this battery boasts an energy density of 200Wh/L—higher than the widely used lithium-ion batteries.

The South Korean tech giant has already created a prototype and is currently testing it with select customers. If testing goes smoothly, mass production is expected to commence by 2026. Initial reports suggest that this revolutionary battery will be featured in upcoming Galaxy Watch models.

One of the standout features of this solid-state battery is its small, flexible design, which overcomes size limitations faced by lithium-ion counterparts. The battery can be manufactured in various sizes depending on customer requirements, ranging from millimeters to centimeters.

In addition to size advantages, solid-state batteries are considered safer, as they use non-flammable solid electrolytes. These batteries have longer lifespans, improved thermal stability, and a lower carbon footprint. Samsung attributes this innovation to its advanced multi-layer ceramic capacitors technology, which enhances durability by preventing volume changes during charging.
