Quasi-elastic neutron studies of superstructure formation in battery materials
LixCoO2 is used extensively in portable batteries in laptops and mobile phones, but the scarcity of Li means that alternative materials are required. Structurally related... -
Influence of superstructures on rich transport properties of lithium cobaltate
In the vicinity of x ~ 0.75, LixCoO2 has potential as a thermoelectric, since it has a high Seebeck coefficient and metallic conductivity. We have performed the first successful... -
Superstructures in insulating and metallic lanthanum-doped sodium cobaltate
The thermoelectric properties of NaxCoO2 can be substantially improved by replacing Na ions by cations of higher valence. Our neutron diffraction studies on SXD for doping with...
