The nickel, manganese, and aluminum (NMA) cathode shows rate capability and specific capacity comparable to NMC or NCA. While high-nickel cathodes are desirable for an increase in energy density, other elements are necessary to stabilize the crystal structure and provide cycling stability. The research group claimed to sidestep the need for cobalt by ensuring even distribution of metal cations through coprecipitating the material rather than substituting via calcination. Funded by an SBIR grant, the researchers started TexPower to begin scaling the lab processes for scale production. Clients should note that NMA benefits from an established supply chain, but converting production to a cost-effective method will require substantial time.
