Background
Lithium nickel manganese cobalt oxides are a class of high voltage positive electrodes for Li-ion batteries. The high nickel content phase, (NMC811), has attracted a lot of research interest due to its high energy density. To date, the NMC811 electrodes are mostly manufactured using nonaqueous slurries with toxic organic solvents (e.g. NMP). The NMC811 has a low stability in water which hinders the use of sustainable water-based slurries. The present thesis focuses on developing surface coatings that protect the NMC811 and enable efficient water-based slurry preparation.
Project Goal
The goal of this project is to establish eco-friendly methods for efficient surface coatings of NMC811. The coated material will be used to prepare water-based slurries and be validated electrochemically in half-cells with metallic Li.
The project will include the following tasks:
