Samsung unveils ultra-small solid-state battery specially designed for wearables

Samsung has unveiled a significant breakthrough in battery technology by introducing the world's first ultra-small solid-state battery for devices wearables.

The new product was announced after three years of research and development by Samsung Electro-Mechanics, which is now entering the testing phase with selected customers.

Mass production is expected to begin in 2026, with the new battery debuting in devices like the Galaxy Watch.

Advances in solid state technology

Solid-state batteries are at the forefront of energy storage innovation, offering several advantages over traditional lithium-ion batteries.

Samsung's new battery has an energy density of 200 Wh/L, significantly higher than that found in current lithium-ion batteries.

This allows the battery to be not only more powerful, but also ultra-compact, meeting the demands of modern wearables, which are increasingly thinner and lighter.

One of the biggest challenges in creating batteries for wearable devices has always been size. Space constraints make it difficult to develop powerful, long-lasting batteries, but Samsung has managed to overcome this barrier.

The new battery can be produced in sizes ranging from millimeters to centimeters, which provides flexibility in design and adaptation to the most varied devices.

Enhanced safety and durability

One of the biggest advantages of solid-state batteries is their resistance to external shocks. Since the solid electrolyte used is non-flammable, there is a lower risk of explosion or leakage, which significantly improves the safety of the device.

Furthermore, this technology allows batteries to have a longer lifespan and greater thermal stability, operating efficiently across a wide range of temperatures.

Samsung has applied a production technology that uses multilayer ceramic capacitors. In this process, thin layers of material are alternately printed and stacked, avoiding the wrinkling problems that occur with conventional batteries.

This allows for minimal change in volume during charging, eliminating the need for extra space to accommodate battery expansion.

Carbon footprint reduction

Another important benefit is that solid-state batteries have a significantly smaller carbon footprint compared to traditional batteries.

Samsung positions this new technology as a more sustainable alternative, aligning with the growing demands for environmentally friendly products.

In addition to being safer and more efficient, solid-state batteries contribute to sustainability by reducing the environmental impact associated with battery production and disposal.

Challenges and opportunities

Although the advantages of solid-state batteries are many, the development of this technology faces challenges, mainly in relation to production costs.

Currently, the manufacturing process is more expensive than that of conventional batteries, which could influence the final price of the devices.

However, Samsung and other companies in the sector are investing in research to reduce these costs, and the expectation is that, as technology advances, solid-state batteries will become more affordable.

Continued progress and future of wearables

Samsung has been making significant progress in solid-state battery technology since introducing the technology in 2020.

At that time, the company highlighted the potential for higher energy densities and greater safety with solid electrolytes.

In July 2024, Samsung launched a pilot production line for solid-state batteries for electric vehicles, which could power cars with a range of up to 600 miles and a charging time of just nine minutes.

For wearables, this new battery represents an important change, allowing devices to be even lighter and thinner, with greater autonomy and safety.

The flexibility of solid-state batteries enables more innovative designs, opening doors to new possibilities in the wearable device market.

In short, Samsung continues to lead the way in battery innovation, and the introduction of the first ultra-small solid-state battery for wearables promises to positively impact the industry by offering a more efficient, safer and sustainable alternative.
