SILI Energy, a next-generation battery materials startup, announced that it has secured additional seed funding from global venture capital firm 500 Global. The investment amount and company value were not disclosed.
SILI Energy is a deep-tech company developing and commercializing next-generation battery anode materials, including silicon composite anodes and lithium metal electrodes. In particular, SILI Energy is addressing the technological limitations of existing lithium electrode materials, such as suppressing lithium dendrite formation and achieving large-area performance, by leveraging ultra-thin, structured lithium metal electrodes and printable lithium metal powders.
The company's silicon composite anode material features a proprietary process and material combination that suppresses volume expansion and improves initial Coulombic efficiency. The lithium metal electrode can be manufactured into foils smaller than 30㎛, and 3D structuring enhances stability. Furthermore, the company has established an eco-friendly recycling process to recover lithium from black powder, embracing a strategy that considers a circular materials supply chain.
The technology has been recognized both domestically and internationally, and has won the Innovation Technology Award and Innovation Product Award at the 2024 Korea Electronics Show (KES) and the 2025 Edison Awards in the United States, respectively.
SILI Energy is securing a raw material and recycling base by collaborating with domestic major corporations and strategic partners, and is currently conducting technology verification and customized material testing with global companies in demand for high-performance batteries for electric vehicles, energy storage systems (ESS), and robots.
Shin Eun-hye, an investment manager at 500 Global, which handled this investment, said, “SILI Energy has an impressive strategy of integrating materials, processes, and recycling, and is a company with high responsiveness even in the face of the restructuring of the global battery supply chain,” adding, “It has great potential to grow into a key materials company in the next-generation battery sector.”
SILI Energy CEO Jeong Gyeong-jin stated, “With this investment, we plan to accelerate prototype advancement and customer verification, and to fully enter the domestic and international markets. We will grow into a company that can make a substantial contribution to the global battery materials ecosystem.”
