Sulfide coating boosts lithium-ion battery lifespan past 1,000 cycles

Among the biggest complaints inhibiting growth in the electric vehicle market is the limited lifespan and range of lithium-ion batteries. Consumers fear being stranded far from home with long wait times at recharging stations. A promising area of research has focused on layer-structured metal oxide cathodes. Specifically, a material known as lithium nickel manganese cobalt oxide, shortened to NMC811, has been the subject of intense study as a cathode material due to its low cost and high energy capacity.
