Coated particulate electrode active materials

Problem

How can microplastics and similar contaminants be removed from wastewater?

Solution

Particulate materials of the composition Li 1+x TM 1 x O 2 wherein x is in the range of from 0.02 to +0.05, TM comprises at least 94 mol-% nickel and up to 6 mol-% of at least three metals M1 selected from Co, Mn, Cu, Mg, Fe, B, Al, Ce, Sn, Zr, Zn, Nb, Ta, Y, Mo and W, wherein said metals M 1 are enriched at the outer surface of the secondary particles of said particulate material, and wherein said particulate material has an average particle diameter (D50) in the range of from 2 to 20 m.

Key novelty

Electrochemical treatment is reinforced by front-page matches on electrode.
