Samsung Electro-Mechanics Leads the Way with Prototype Development of Miniature Solid-State Batteries, Mass Production Expected in the First Half of 2026

According to a report by South Korean media outlet MK, Samsung Electro-Mechanics successfully developed a prototype of a miniature solid-state battery suitable for wearable devices last month. The company is currently conducting tests with clients and expects to begin mass production in the first half of 2026. This breakthrough marks a significant advancement for Samsung Electro-Mechanics in the solid-state battery field and signals an acceleration in the evolution of wearable device battery technology.

In the development of its miniature solid-state battery, Samsung Electro-Mechanics leveraged its leading expertise in MLCC (Multilayer Ceramic Capacitor) technology. The new product is said to possess the following outstanding features:

• Enhanced Stability and Reduced Explosion Risk: Solid-state batteries utilize solid electrolytes, significantly improving safety compared to traditional lithium-ion batteries and drastically reducing the risk of explosion, making them more suitable for wearable devices that are close to the body.

• High Energy Density: Samsung Electro-Mechanics' miniature solid-state battery boasts an energy density of 200Wh/L, enabling it to store more energy in the same volume compared to traditional lithium-ion batteries. This translates to a significant increase in the battery life of wearable devices.

• Miniaturization and Compatibility with Diverse Form Factors: The solid electrolyte in solid-state batteries allows for the creation of thinner, lighter batteries, making them more adaptable to the size and shape requirements of wearable devices. This also opens up more possibilities for miniaturization in future smartphones and other electronic products.

Samsung Electro-Mechanics plans to initially implement this miniature solid-state battery in its own wearable devices, including Galaxy Ring, Galaxy Watch, and Galaxy Buds. It aims to expand its application to smartphones and other electronic products in the future. To ensure the market competitiveness of its miniature solid-state battery products, Samsung Electro-Mechanics will establish a dedicated task force within the company to provide supply to major clients, including Samsung Electronics.

The South Korean media reports suggest that Samsung Electro-Mechanics will continue with technological research and development while actively collaborating with clients. The company aims to achieve price competitiveness with traditional lithium-ion batteries and rapidly scale up production to meet market demand.

The mass production of Samsung Electro-Mechanics' miniature solid-state batteries signifies a battery technology revolution in the wearable device market. Safer, more efficient, and smaller batteries will fuel the expansion of functionalities and application scenarios for wearable devices, paving the way for new developments across the entire electronics industry.
