摘要:
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.
