PNNL: single-crystal nickel-rich cathode holds promise for next-generation Li-ion batteries

Green Car Congress

High-energy nickel (Ni)–rich cathode will play a key role in advanced lithium (Li)–ion batteries, but it suffers from moisture sensitivity, side reactions, and gas generation. Nickel offers relatively low cost, wide availability and low toxicity compared to other key battery materials, such as cobalt.
