Samsung is on track to meet its timeline for delivering an oxide solid-state battery with the highest energy density in the industry. Initially setting a goal of introducing prototypes in 2025, the company has confirmed that its solid-state battery technology is now ready ahead of schedule. The solid-state batteries, capable of achieving up to 500 Wh/kg energy density, are expected to deliver a significant capacity-to-size ratio, positioning Samsung to lead the industry in this area.
With mass production facilities now in development, Samsung plans to integrate these batteries into devices, including wearables such as its Galaxy Ring fitness tracker, by 2026. The oxide-based solid-state battery is noted for its stability, which allows for smaller, flexible cells suitable for a range of applications, beyond just electric vehicles. These batteries are seen as a major step forward in energy storage, thanks to their high energy density and reduced manufacturing costs.
The breakthrough in production comes with the adoption of roll pressing technology, a method that significantly accelerates the manufacturing process. This eliminates the need for the traditional Warm Istactic Press (WIP) process, which has previously been a bottleneck in solid-state battery production. By simplifying and speeding up the manufacturing process, Samsung is positioning itself to overcome key barriers, including production speed and costs, which have hindered the mass adoption of solid-state batteries.
The company expects to expand the application of its solid-state batteries in 2027, when they will be ready for integration into electric vehicles. This coincides with similar timelines set by competitors like Toyota and CATL, indicating that the solid-state battery technology is nearing the threshold for mainstream use in electric transportation.
