More nickel in a battery means it can store more energy. Ni NMA outperforms both NMC and NCA and only slightly trails NMCAM and a commercial cathode after 1000 deep cycles. Typically, increased energy density leads to trade-offs, such as a shorter cycle life. However, the researchers said they’ve overcome the short cycle life and poor rate capability problems through finding an optimal combination of metals and ensuring an even distribution of their ions.
