Methods and systems are provided for a battery cathode material comprising greater than or equal to 60% nickel content, the cathode material having at least one metal doped therein. In one example, a method comprises doping the at least one metal into the cathode material using water as a solvent, wherein the at least one metal has an ionic radii greater than 60 picometers. The at least one metal may be selected from strontium (Sr), barium (Ba), rubidium (Rb), cesium (Cs), zirconium (Zr), niobium (Nb), molybdenum (Mo), technetium (Tc), ruthenium (Ru), tungsten (W), platinum (Pt), neodymium (Nd), yttrium (Y), and cerium (Ce).

Method and systems for metal doping on battery cathode materials

Methods and systems are provided for salt-rinse surface doping of electrode materials for lithium-ion batteries. In one example, a method may include dissolving a dopant salt in a solvent to form a dopant salt rinse solution, rinsing an electrode active material with the dopant salt rinse solution to form a coated electrode active material, and heating the coated electrode active material to form a doped electrode active material. In some examples, a surface region of the doped electrode active material may include a uniform distribution of dopants from the dopant salt rinse solution. In this way, the electrode active material may be rinsed and doped via the dopant salt rinse solution in a single-stage process.

Methods and systems for salt-rinse surface doping of electrode materials

An abrasive article comprising a first group including a plurality of shaped abrasive particles overlying a backing, wherein the plurality of shaped abrasive particles of the first group define a first non-shadowing distribution relative to each other.
