Oak Ridge National Laboratory researchers have developed a potential replacement for cobalt-based cathodes in li-ion batteries called NFA (nickel-, iron- and aluminum) – a derivative of lithium nickelate. “Lithium nickelate has long been researched as the material of choice for making cathodes, but it suffers from intrinsic structural and electrochemical instabilities,” says ORNL’s Ilias Belharouak, “in ...
