NEO Silicon Anode Nanocoating Technology


NEO Battery Materials Ltd. patented technology utilizes robust nanocoating layers for silicon (Si) anodes. Our technology effectively scatters the stress from the Si anode, compensating mechanical stress during a long-term cycling test.

Dr. Jong Hyeok Park, Director and Chief Scientific Advisor, is currently leading the research and development of the silicon anode technology. Dr. Park was previously a Senior Researcher for LG Chem with over a total of 92 patents and co-invented the world’s first safety-reinforced separator (SRS). He is currently a Professor of Chemical and Biomolecular Engineering at Yonsei University.

We are currently collaboratively developing our proprietary technology with Yonsei University-Industry Foundation (YUIF) in South Korea. Any potential IP rights resulting from the Collaboration will be wholly owned by NEO Battery Materials.

Two-Track NEO Si Anode Development


NEO is currently in a two-track development of its anode on 1) Si nanoparticles and 2) Si microparticles

Silicon nanoparticles partially resolve the cracking issue during lithium insertion when charging, but the technical and engineering difficulty of manufacturing results in high input costs. On average, silicon microparticles are known to be 8 to 10 times more cost-effective than nanoparticles; however, the problem lies with the performance at the micron size.

NEO is hence developing its nanocoating technology with both Si nano and microparticles to enable mass adoption into lithium-ion batteries. In a recent test, NEO has achieved performance effectiveness with Si microparticles, enabling a 6-minute charging level without major capacity loss in the cell.
