A significant advancement in energy storage technology has been made by Samsung with the release of the first ultra-small solid-state battery for wearable technologies. Developed by Samsung Electro-Mechanics over three years, this revolutionary battery boasts an energy density of 200Wh/L, substantially higher than ordinary lithium-ion batteries.
The battery is presently being tested by the South Korean electronics giant on a small group of consumers, having already produced a prototype. By 2026, if all goes according to plan, mass manufacturing should start. Depending on the needs of the user, this unique battery can be built in a range of sizes, from millimeters to centimeters, and is designed to overcome size limits.
Solid-state batteries, like the one Samsung has unveiled, are recognized as safer substitutes since they charge and discharge using solid electrolytes that don’t catch fire. They are therefore more resilient to shocks from the outside. Furthermore, the battery can reduce volume fluctuations during charging thanks to Samsung’s experience in multi-layer ceramic capacitor technology, which makes it a perfect fit for small and lightweight wearables like the Galaxy Watch.
In comparison to conventional batteries, these batteries have longer lifespans, better thermal stability, and a less carbon footprint. Solid-state batteries possess the capacity to transform the energy storage industry due to their adaptability and temperature tolerance.
However, there are challenges to address, primarily the high production cost. Despite this, companies like Samsung are actively working on solutions. The introduction of this solid-state battery for wearables is just the beginning, with further applications, including electric vehicles, expected to benefit from this technology. Samsung is poised to lead this innovation wave, with promises of better safety, performance, and sustainability.
