Recycling positive-electrode material of a lithium-ion battery

Title: Recycling positive-electrode material of a lithium-ion battery

Abstract

Examples are disclosed of methods to recycle positive-electrode material of a lithium-ion battery. In one example, the positive-electrode material is heated under pressure in a concentrated lithium hydroxide solution. After heating, the positive-electrode material is separated from the concentrated lithium hydroxide solution. After separating, the positive electrode material is rinsed in a basic liquid. After rinsing, the positive-electrode material is dried and sintered.

High valent lithiated surface structures for lithium ion battery electrode materials

Patent Croy, Jason; Balasubramanian, Mahalingam; Park, Joong Sun

The surface of a lithium ion cathode material (e.g., a lithium metal oxide material capable of releasing and accepting lithium ions during charging and discharging, respectively, of a lithium ion electrochemical cell) is coated with a lithium metal oxide (LMO) material comprising a high-valent metal to, inter alia, reduce interfacial resistance toward lithium exchange. Li-rich phases on the surface of the treated LMO particles allow for better lithium ion diffusion. The inclusion of elements that form phases with lithium and can substitute in the host structure allow for mixing across interfaces leading to more robust structures that better mimic epitaxial-typemore »« less

Positive electrode for a lithium battery

Patent Park, Sang-Ho; Amine, Khalil

A method for producing a lithium alkali transition metal oxide for use as a positive electrode material for lithium secondary batteries by a precipitation method. The positive electrode material is a lithium alkali transition metal composite oxide and is prepared by mixing a solid state mixed with alkali and transition metal carbonate and a lithium source. The mixture is thermally treated to obtain a small amount of alkali metal residual in the lithium transition metal composite oxide cathode material.
