NEO advances silicon anode technology

TORONTO — NEO Battery Materials makes technological advancements in the company’s silicon anode technology – longer battery capacity retention while sustaining low costs.

The company’s engineering team has modified existing additives to enhance two coating methods, improving key performance metrics such as longer capacity retention, higher and stable Coulombic efficiency and faster charging rates.

NEO’s silicon anode, NBMSiDE, has shown high Coulombic efficiency, meeting industry standards. The product is effective in full-cell designs using pure silicon or silicon-graphite anodes. The company is working on further optimization and commercialization of NBMSiDE.

Spencer Huh, director, president and CEO of NEO, said, “We are highly proud of NEO’s engineering team and enthusiastic about the results achieved with our NBMSiDE products. This year, we plan to reach new technology highs with silicon-graphite anodes and in full cells. Additionally, our team has initiated recycled silicon evaluations with Lotus Energy and INNOX eco-M products.”

NEO is also exploring silicon-carbon (Si-C) and silicon-graphite anode development, responding to industry demand. A new Si-C anode product will be introduced soon.

First coating enhancement utilizes polymer characteristics to stabilize the silicon surface during expansion, reducing adverse side reactions and preventing delamination. The second coating enhancement adds protective layers to the silicon surface to further reduce side reactions and increase mechanical strength, leading to improved capacity retention.
