Korean startup SILI ENERGY, which specializes in developing next-generation secondary batteries and solid-state battery anode materials, has secured additional seed funding from Korea Investment Accelerator. This follows their earlier seed investment from Seoul Techno Holdings. The new funds will be used to enhance the development of technologies for silicon composite materials, lithium metal powders, and electrodes, and to expand their team.

Founded in 2023 by CEO Jeong Kyung-jin, who has over 20 years of experience in secondary battery material and electrode technology at major Korean corporations, SILI ENERGY has accumulated over 100 patents and academic publications. Jeong is a certified Quality Engineer (CQE) by the American Society for Quality, a TRIZ Specialist, and a pioneer in solid-state battery research in Korea.

While traditional secondary batteries use carbon-based graphite anodes, silicon and lithium materials offer more than ten times the capacity of graphite. However, they face challenges such as silicon expansion and lithium dendrite formation, which can degrade battery lifespan.

SILI ENERGY’s technology has demonstrated top global performance in initial charge and discharge capacity, efficiency, and capacity retention. The company is rapidly advancing by working on projects with major domestic and international secondary battery material and cell companies, thanks to its unique technological edge.

Korea Investment Accelerator noted, “SILI ENERGY has developed fundamental technology that effectively addresses issues like swelling in silicon anodes and uneven lithium growth in lithium metal electrodes. We believe this positions them as a potential key player in the secondary battery anode market, which led us to invest.”

CEO Jeong Kyung-jin stated, “Innovation in secondary battery materials is crucial for improving the operational time, charging speed, and safety of electric vehicles, robots, and drones. Our technology and materials fully meet the demands of next-generation secondary battery power sources.” He also mentioned, “We are developing technology to recover lithium from waste silicon and black powder generated in domestic industries, which will contribute to resource independence and enhance the security of the domestic supply chain for critical secondary battery materials.”
