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.Scientists led by Warwick University in the UK investigated the effect of ambient atmosphere exposure during production or storage on nickel-rich cathodes, finding that keeping the materials free of moisture is key to ...
