NEO’s modified CNT nano-coating technology improves the service life and durability of micrometer-sized silicon metallurgical anodes
Vancouver, British Columbia – (Newsfile Corp. – July 30, 2021) – Dr. JH Park, Director and Senior Scientific Advisor to NEO Battery Materials Ltd. (TSXV: NBM) (OTC: NBMFF) (“NEO” or “Company”) is pleased to announce details of NEO’s innovation in using modified carbon nanotubes (CNTs) as a new material to make them more durable, cheaper, and mechanical more durable silicon anode active materials are used.
Theoretically, CNTs are known to have an electrical conductivity similar to that of copper and to have a strength more than 100 times that of steel. In addition, conventional carbon fibers are known to break easily at 1% elongation, but CNTs have shown the ability to retain their structural properties at 15% elongation.
Because of this ability to withstand mechanical loads, CNT can act as an effective damper for the problem of volume expansion of silicon anodes during charge and discharge cycles. In addition, the superior electrical conductivity of the material enables the anode’s performance to be maximized. Large battery manufacturers like LG Chemical are actively considering CNT as an additive to their next generation battery line and are aggressively aiming to increase production of CNTs.
NEO modified CNT nano-coating technology
Despite the excellent electrical conductivity, when mixed with silicon particles, there has been difficulty in maximizing the benefits of CNTs due to the lack of affinity between the two materials. NEO has thus secured the technology for functionalizing the surface of CNTs and has confirmed that the surface-treated CNTs have an extraordinary affinity for the silicon particles. The modified CNTs can be used as an effective material in NEO’s silicon nano-coating technology.
NEO’s modified CNTs may have a new morphology, and this confirms that NEO’s technology enables conformal coating in the nanometer range on all silicon particle surfaces. The analysis of the battery properties confirms that the service life is drastically improved compared to conventional CNTs which are applied to micrometer-sized metallurgical silicon anodes. With NEO’s one-step one-pot solution process, a process for mass production of the modified CNTs is currently being designed.
