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

Green Car Congress

Nickel offers relatively low cost, wide availability and low toxicity compared to other key battery materials, such as cobalt. The PNNL researchers have developed a process to grow high-performance crystals in molten salts—sodium chloride, common table salt—at high temperature.
