Help make the next generation Li-ion batteries happen

Li-ion batteries are currently fabricated with N-Methylpyrrolidone (NMP) as a solvent in electrode slurries. As NMP is a restricted chemical, it needs careful monitoring and controlled disposal which is essential for the enironment, health and safety, but imposes a large cost to the manufacturing process. Therefore, enviromentally friendly aqueous alternative are being pursued. However, water is a comtaminant in Li-ion batteries seriously affecting cell performance and life time. In this thesis, you will use electrochemical techniques to study the reaction of water at Li-ion cathodes and evaluate buffer layers to prevent exchange of Li-ions of the electrode with protons from the water, one of the most common degradation processes.
