Real time neutron radiography and neutron tomography for lithium ion batteries with new cathode materials

Abstract: Lithium ion batteries (LIBs) have been increasingly used in electric transportation and storage of electricity generated from renewable sources. Current LIBs mainly use LiNixMnyCozO2 (NMC) cathode materials due to their high capacities and specific energy. Here, we develop a new family of cathode materials with disordered rocksalt (DRX) crystal structure that can further increase capacity. However, the DRX materials usually exhibit sluggish Li+ ion diffusion and the capacity decreases rapidly over cycling. We will assemble two types of LIBs, one containing the conventional NMC cathode material, and the other containing our synthesised DRX cathode material. We plan to use real time neutron radiography and neutron tomography to study Li+ ion diffusion and 3D electrode structural changes during battery charging and discharging, and compare between the two types of the batteries to shed light on the behaviour of the different cathode materials.
