For anyone else curious, NMC is probably https://en.wikipedia.org/wiki/Lithium_nickel_manganese_cobalt_oxides https://en.wikipedia.org/wiki/Lithium_nickel_manganese_cobal... > Lithium nickel manganese cobalt oxides (abbreviated Li-NMC, LNMC, or NMC) are mixed metal oxides of lithium, nickel, manganese and cobalt. They have the general formula LiNixMnyCozO2. ... NMCs are among the most important storage materials for lithium ions in lithium ion batteries. They are used on the positive side, which acts as the cathode during discharge.
