NEO Battery Materials Ltd. launches three silicon anode material products for high-performance lithium-ion batteries
NEO Battery Materials said it is "on schedule to target the semi-commercial scale production of the materials by the end of 2022"

NEO Battery Materials Ltd. (TSX-V:NBM) said it has launched three types of silicon (Si) anode active materials — NBMSiDE-P100, NBMSiDE-P200, and NBMSiDE-C100 — and is on schedule to target the semi-commercial scale production of these materials by the end of 2022.

The Vancouver-based company which is focused on battery metals and materials said the three types of products are manufactured through its 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 anode, it said.

“NEO's technology significantly improves the life span and cycling stability compared to conventional metallurgical silicon-based particles,” noted the company.

In a statement, NEO Battery CEO Spencer Huh said: "We are very glad to bring the three types of silicon anode active prototypes to the market as a result of valuable research and development for the past even years.”

“All our business developments are aligning our strategy, and we have complete confidence in pushing towards the semi-commercial plant facility in South Korea. NEO is positioning itself as a low-cost, robust Si anode materials supplier for electric vehicle lithium-ion batteries," he added.

NEO said that by securing the product pipeline of silicon anode materials, it will be able to respond “more efficiently” to the various needs of battery materials that are compatible in the lithium-ion battery cell system. The company is currently working towards adding two more product pipelines of silicon anode active materials to meet market needs.

As one of the pipelines, NEO is speeding up development of its 100% pure silicon anode based on carbon nanotube (CNT) conductive additives, and new robust binder technologies. The firm said it is currently conducting research and progressing commercialization projects regarding the graphite/silicon composite anode through active collaboration with companies that have signed non-disclosure agreements.

Meanwhile, NEO Director Dr JH Park, who is the company’s chief scientific advisor noted that NEO is aiming at “uniquely manufacturing the silicon anode materials through a continuous process,” unlike existing rechargeable battery material production methods.

“Our process that effectively reduces the cost of Si anode production will act as a stark point of differentiation compared to existing and potential competitors," he added.

NEO said it has submitted the application for the trademark of its silicon anode active material products through its South Korean intellectual property law firm.

All three products, NBMSiDE-C100, NBMSiDE-P100, and NBMSiDE-P200, represent different nanocoated materials with modifications to match specifications asked for by various battery manufacturers.
