NCA
NCA, which stands for Nickel Cobalt Aluminum, is a popular type of material used in making rechargeable batteries, especially for electric vehicles and energy storage. Think of it as a special recipe that makes batteries work better and last longer. It's one of several common materials (others include NMC and LFP) that companies use to make the crucial parts inside lithium-ion batteries. When you see NCA mentioned in someone's resume, they've likely worked with either making these materials, designing batteries using them, or testing how well they perform.
