Lithium-ion batteries (LIBs) are the powerhouse of modern electronics and electric vehicles (EVs), and their performance hinges on the cathode materials. Among these, ternary cathode materials such as NCM (Nickel-Cobalt-Manganese oxides) and NCA (Nickel-Cobalt-Aluminum oxides) dominate due to their balanced energy density and stability. However, varying the ratios of nickel (Ni), cobalt (Co), mang...read more
