摘要:
A lithium transition metal oxide powder for use in a rechargeable battery is disclosed, where the surface of the primary particles of said powder is coated with a LiF layer, where this layer consists of a reaction product of a fluorine-containing polymer and the primary particle surface. The lithium of the LiF originates from the primary particles surface. Examples of the fluorine-containing polymer are either one of PVDF, PVDF-HFP or PTFE. Examples of the lithium transition metal oxide are either one of - LiCo d MeO 2 , wherein M is either one of both of Mg and Ti, with e 1 + a M' 1 -a O 2±b M 1 k S m with -0.03 1 consisting of either one or more elements of the group Ca, Sr, Y, La, Ce and Zr, with 0≤k≤0.1 in wt%; and 0 a Ni x CO y M" z O 2±e A f , with 0.9
