▎ 摘　　要

NOVELTY - A method for salt-rinse surface doping of electrode material involves dissolving a dopant salt in a rinsing solvent (106) to form a dopant salt rinse solution; rinsing an electrode active material with the dopant salt rinse solution to obtain a uniformly surface-coated electrode active material; and heating the uniformly surface-coated electrode active material to form a uniformly surface-doped electrode active material. USE - A method for salt-rinse surface doping of electrode material. ADVANTAGE - The salt-rinse surface doping process may improve cycling of a finally-formed lithium-ion cell incorporating the surface-doped electrode active material relative to the surface-doped electrode active material formed from the typical rinsing and doping process. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) method which involves dissolving a metal salt in a rinsing solvent (106) to form an aqueous rinse solution; and mixing a cathode active material (102) with the aqueous rinse solution to form a mixture; and, without any further rinsing, isolating a coated cathode active material from the mixture; heating the coated cathode active material to obtain a surface-doped cathode active material; and forming a cathode slurry comprising the surface-doped cathode active material; and (2) doped cathode material, comprising nickel manganese cobalt (NMC); and a dopant comprising an ion of any one of aluminum (Al), magnesium (Mg), manganese (Mn), cobalt (Co), nickel (Ni), titanium (Ti), zirconium (Zr), tin (Sn), copper (Cu), calcium (Ca), lanthanum (La), cerium (Ce), yttrium (Y), neodymium (Nd), tungsten (W), sodium (Na), potassium (K), vanadium (V), niobium (Nb), molybdenum (Mo), iron (Fe), zinc (Zn), fluorine (F), chlorine (Cl), bromine (Br), sulfur (S), selenium (Se), phosphorus (P), antimony (Sb), silicon (Si), germanium (Ge), gallium (Ga), and/or boron (B) where the dopant is uniformly doped into a surface region of the NMC, and less than or equal to 10000 ppm residual lithium salts are present at a surface of the doped cathode material. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the manufacturing process of lithium-ion battery pack including a cathode formed via an electrode slurry manufacturing process.
