1. R&D Achievements and Full Cell Testing Activities

    

   NEO Battery Materials is advancing its silicon anode technology through a proprietary single-step manufacturing process with cost-effective silicon microparticle inputs that provides significant cost reductions and performance enhancements for the lithium-ion battery end-user. Through a mix of treatments and nanocoating materials, NEO utilizes pure metallurgical-grade silicon particles, which provide a 40-70% higher initial specific energy or capacity compared to current competitors that employ SiOx, SiC, or other composite silicon materials.

   Due to NEO’s advantage of retaining a higher initial capacity, on average, a 5% silicon weight loading of NBMSiDE can have the equivalent impact of a 10% loading of a competitor’s materials. Initial coulombic efficiencies (ICE) for NEO’s 100% micron-size level Si anode have exceeded the 86% level, and cycling performance presents excellent capacity retention after 300 charging/discharging cycles even with inexpensive and conventional polymer binders and super-P carbon black conductive additives.

   With the near completion of pouch cell manufacturing, the full cell testing process with NBMSiDE™ is in progress in South Korea, and the Company will continue to conduct continuous cycling tests to both examine and optimize performance in the full cell setting. Due to the recent rapid spread of the Omicron virus in Korea, there was a delay due to internal circumstances of the testing agency, but fortunately, NEO has received notice that the regular testing schedule will occur accordingly. The Company will shortly provide the completed production and details of the full pouch cells.
