SiLi Energy, a South Korean startup specializing in next-generation battery materials, has secured additional seed funding from 500 Global. The company is focused on commercializing advanced silicon composite anode materials and is pioneering the development of ultra-thin, structured lithium metal electrodes, often regarded as the ultimate anode material. Especially, by manufacturing the ultimate anode material — lithium metal electrodes — in an ultra-thin, structured form, and applying printing technology using lithium metal powder, the technology addresses issues such as lithium dendrite formation and large-area scalability.This technology positions SiLi Energy to provide a comprehensive anode solution for next-generation batteries.

SiLi Energy’s silicon anode material employs proprietary process technology and composition to suppress volume expansion while maximizing initial Coulombic efficiency. Its ultra-thin lithium electrodes, fabricated as foils thinner than 30 micrometers, utilize a 3D structured design instead of a conventional 2D planar form, effectively mitigating lithium dendrite growth.

Additionally, SiLi Energy has developed a sustainable, circular supply chain by recovering lithium from black powder. The company’s lithium anode technology and products have garnered global recognition, earning the Innovation Technology Award and Innovation Product Award at the 2024 Korea Electronics Show and the 2025 Edison Awards, marking a first for a global anode material company.

SiLi Energy has secured raw material and recycling supply chains through partnerships with major domestic corporations and strategic collaborators. The company is actively conducting technology validation and customized material supply tests with global enterprises in high-performance battery markets, including electric vehicles, energy storage systems, and robotics.

Eunhye Shin, a partner at 500 Global, stated, “SiLi Energy is a rare domestic company with an integrated strategy encompassing materials, processes, and recycling. It holds significant potential to become a key supplier in the next-generation battery market. With its pilot production infrastructure and domestic raw material base, SiLi Energy is well-positioned to address global supply chain shifts, such as those driven by the Inflation Reduction Act (IRA).”

Kyungjin Jung, CEO of SiLi Energy, remarked, “This investment will accelerate prototype development and customer validation, paving the way for our entry into domestic and global next-generation battery markets. Starting in Korea, we aim to grow into a company that contributes significantly to the global battery material ecosystem.”
