Crystallographic structure of disordered rock-salt materials
Li-ion batteries are a key technology to reduce CO2 emissions. The current generation of batteries rely on cathode materials either rich in Co or in Ni and with a layered structure. However these elements are limited and expensive, motivating the search for alternative cathodes with reduced Ni content and no Co, but retaining high specific capacity. One possible alternative are disordered rock salt materials, and in particular we are investigating Ni and Ti based disordered rock salt oxides. After verifying the unit cell size by XRD in our lab (as well as the materials´ electrochemical behaviour) we now seek to investigate the cationic distribution of the different elements (Li,Ni,Ti) for samples prepared under different conditions. These elements are well suited to be investigated by neutrons diffraction, and in combination with XRD and ICP-OES we aim at fully describing the cationic distribution in the materials. Moreover, we aim at investigating by operando neutron diffraction the crystallographic changes occurring in such materials during Li deinsertion (volume change, phase transitions, etc).
