Title:
USE OF LITHIUM SECONDARY ELECTROCHEMICAL CELLS CONTAINING A BLEND OF A LITHIUM NICKEL OXIDE AND A LITHIUM MANGANESE IRON PHOSPHATE FOR AUTOMOTIVE APPLICATIONS
Document Type and Number:
WIPO Patent Application WO/2021/259991
Kind Code:
A3
Abstract:
The use of a blend of a lithium nickel oxide and a lithium manganese iron phosphate as an active material composition in the cathode of a lithium secondary electrochemical cell for automotive applications, such as hybrid and electric vehicles. This blend allows decreasing the porosity of a lithium manganese iron phosphate-based cathode. It also allows improving the detectability of a gas release in the cell in case of an abnormal operation of the cell. It allows lowering the cell impedance at a low state of charge, typically less than 30 %, and reducing the impedance increase of the cell during the cell lifespan.
