SK On, a leading player in battery technology, has made significant advancements in the development of all-solid-state batteries (ASSBs), a next-generation power solution that promises improved performance and safety. These batteries replace the liquid electrolytes found in traditional lithium-ion batteries with solid alternatives, offering a more stable and efficient energy storage system. Solid electrolytes are primarily classified into three types: sulfide-based, oxide-based, and polymer-based.
The company has been actively collaborating with esteemed academic institutions and recently shared its pioneering research in prestigious international journals, along with numerous patent applications. One of the standout studies, conducted with the Korea Institute of Ceramic Engineering and Technology, focuses on the use of photonic sintering technology to enhance oxide-rich hybrid solid electrolytes. This innovative technique employs intense light to strengthen material bonds, improving the durability of the electrolytes.
In addition, SK On has worked with Seoul National University to investigate the potential of lithium- and manganese-rich layered oxide (LMRO) cathodes in sulfide-based ASSBs. This collaboration has highlighted challenges such as gas generation and voltage decay in traditional approaches, but it also offers promising solutions to enhance battery longevity and performance.
With these innovations, SK On continues to push the boundaries of energy storage technology, positioning itself at the forefront of the battery development industry.
