Nano One Materials has developed a breakthrough in longevity for a cobalt free high voltage battery that has been successfully demonstrated at automotive rates of charge and discharge for over 900 cycles. This demonstration battery uses a low cost, cobalt-free Lithium Nickel Manganese (LNM) cathode active material made with Nano One's proprietary one-pot process. Nano One's LNM cathode was tested at 25oC in a conventional electrolyte with a graphite anode in a 20-layer 126mAh (0.592 Wh) pouch cell. Ongoing tests are equally encouraging for elevated temperatures. LNM is also known as high voltage spinel (HVS) and is a strong candidate for next generation, solid state batteries where its dimensional stability provides a stable interface with solid electrolytes. Currently, several independent evaluations are underway on Nano One LNM material within the automotive supply chain where the Nano One technology may impart greater and much needed stability.
