NEO Silicon Anode Nanocoating Technology

NEO Battery Materials Ltd. patented technology utilizes proprietary 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 a total of over 95 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.

NEO Battery Materials is currently collaboratively developing its 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.


The three types of products, NBMSiDE-P100, NBMSiDE-P200, and NBMSiDE-C100 are manufactured through NEO’s proprietary nanocoating technology and are based on metallurgical-grade silicon with purities of at least 99.95%. NEO’s products have all achieved an initial coulombic efficiency (ICE) greater than 86%, and high specific capacity (>2500 mAh/g). In addition, an ICE of 92% or higher can be attained when NEO’s silicon is mixed with existing graphite anodes. NEO’s technology significantly improves the life span and cycling stability compared to conventional metallurgical silicon-based particles. The Company is on schedule to target the semi-commercial scale production of these materials by the end of 2022.
