An electric car that runs more than 1,000 kilometers on a single charge is no longer a dream performance. As the next generation of batteries that exceed the capacity limits of commercial lithium-ion batteries, silicon batteries are the closest technology to practical use. The silicon battery has an energy density of a maximum of 10 times that of a conventional lithium-ion battery and is capable of charging and discharging faster. However, solving the large volume expansion issues of 4-5 times the size of the battery during the charging/discharging process is a major challenge in this R&D field. Our only patented technology provides a solution to these critical problems and provides a critical foundation for the realization of next-generation silicon batteries.

The most important technical challenges in electric vehicle batteries are high energy density, fast charging time, low-temperature performance and safety to improve driving mileage. We develop technologies that can improve battery performance most effectively without compromising existing standard manufacturing processes. Through the development of new highly functional additive materials, we successfully inhibit the generation of the dendrite, which was a chronic problem of lithium metal batteries, and thus improve the lifetime and stability of the battery performance.

The design of an electrolyte system, such as a highly functional electrolyte additive or electrolyte salt, is one of the low-cost, high-effectiveness solutions that can improve battery performance most effectively while minimizing current process changes. Based on proprietary patent and material technologies, we design and develop stable next-generation electrolyte systems that can be applied to a wide range of secondary batteries from lithium-ion to lithium-metal batteries.
