NEO Battery Materials Ltd. announced that the Korean Intellectual Property Office (KIPO) has issued Notices of Allowance for two patents covering its P-100 and P-200 silicon-based anode materials for lithium-ion batteries. Filed in June 2023, the patents—Silicon-Based Active Anode Material for Lithium Secondary Battery and Manufacturing Method Thereof I and II—protect both the unique material properties and proprietary manufacturing processes for NEO’s P-100 and P-200 products.
Silicon Patent I secures the critical milling step in which low-cost metallurgical silicon is transformed into a core-shell composite structure featuring a silicon core surrounded by an amorphous silicon oxide layer. Silicon Patent II covers the subsequent nanocoating and additive technology that applies a uniform thin polymer nanolayer to the composite core, completing the engineered core-shell architecture. These filings mark NEO’s first independently developed intellectual property beyond its existing licenses and collaborations with the Yonsei University-Industry Foundation.
The company is directing technical resources toward integrating the P-200 series into batteries for short-duration, high-capacity electronics applications, including drones, defense technologies, and remote-controlled systems. Offering a specific capacity of up to 2,500 mAh/g—nearly double the industry average of 1,300 mAh/g—the P-200 series is positioned to meet the energy and power demands of compact electronic platforms.
“Due to lower validation barriers for electronics compared to larger applications like electric vehicles, NEO expects that the P-200 series to have an expedited adoption timeline in existing electronics battery systems,” commented Dr. J.S. Jeoung, SVP of Cell Development. “Targeting the electronics sector provides a strategic entry point with reduced commercialization friction, potentially enabling earlier revenue generation. NEO can also further access additional commercialization channels while continuing to advance long-cycle life products like the P-300N.”
Upon completion of required post-filing documentation, the patents will be formally issued and registered. NEO Battery Materials, listed on the TSX Venture Exchange and OTC, is a Canadian technology company focused on low-cost silicon anode materials for electric vehicles, electronics, and energy storage. Its proprietary manufacturing process aims to enable longer-running, ultra-fast-charging lithium-ion batteries.
