Korean patent office grants NEO Battery two silicon anode patents

TORONTO - The Korean Intellectual Property Office (KIPO) has issued Notice of Allowances for two patents related to NEO Battery Materials Ltd.’s (TSXV:NBM) (OTC:NBMFF) P-100 and P-200 silicon battery materials, the company announced Wednesday. The micro-cap company, currently valued at $43.33 million, has seen its stock surge an impressive 476% over the past year, reflecting strong investor interest in its innovative battery technology.

The patents, titled "Silicon-Based Active Anode Material for Lithium Secondary Battery and Manufacturing Method Thereof I" and "Silicon-Based Active Anode Material for Lithium Secondary Battery and Manufacturing Method Thereof II," protect the material properties and manufacturing processes of the company’s silicon anode products.

According to the press release statement, the first patent secures the milling process for low-cost metallurgical silicon to form a core-shell composite structure, while the second patent covers nanocoating and additive technology to create a polymer nanolayer on the silicon core.

NEO Battery is focusing on integrating its P-200 series for short-duration, high-capacity electronics applications, particularly in drones and defense technology systems. The company claims the P-200 offers a capacity of 2,500 mAh/g, compared to an industry average of 1,300 mAh/g. With a beta of 2.81, investors should note the stock’s higher volatility compared to the broader market.

Dr. J.S. Jeoung, SVP of Cell Development at NEO Battery, stated that targeting the electronics sector provides "a strategic entry point with reduced commercialization friction" due to lower validation barriers compared to larger applications like electric vehicles.

The patents were submitted in June 2023 and will be officially registered upon completion of post-filing documentation. These are the first intellectual property rights independently developed by NEO Battery, separate from existing patents licensed and developed with the Yonsei University-Industry Foundation. According to InvestingPro analysis, the company currently shows a Weak financial health score, suggesting investors should closely monitor its commercialization progress and financial metrics.

In other recent news, NEO Battery Materials Ltd. has announced significant advancements in its silicon anode technology. The company revealed that its advanced silicon battery, the P-300N, has surpassed its performance targets during long-term capacity testing. Specifically, the P-300N demonstrated over 90% capacity retention after 300 charging cycles, which exceeds the company’s initial goal of 80% retention for the same number of cycles. This achievement highlights the P-300N’s stability, as it utilizes metallurgical silicon, a cost-effective material in the battery supply chain. Additionally, Dr. Jun Sik Jeoung, who brings over 17 years of experience in battery development, has been appointed as Senior Vice President of Commercialization & Cell Development. He will lead the company’s efforts in scaling its technology. These developments are part of NEO’s ongoing commitment to advancing its battery materials.
