Investigating moisture in nickel-rich batteries
Scientists in the UK looked into the effects of exposure to ambient atmosphere could have on nickel-manganese-cobalt cathodes for lithium-ion batteries. While many cathode designs are moisture sensitive, the group found that the nickel-rich cathodes currently gaining market share are especially vulnerable, and can suffer irreversible power loss upon exposure to moisture in the air.

Batteries could shrink even more with smaller crystals in the cathodes. Battery packs in electric vehicles and consumer goods could become smaller, while still offering high performance.
