We have studied low-temperature magnetic properties as well as
high-temperature lithium ion diffusion in the battery cathode materials
LixNi1/3Co1/3Mn1/3O2 by the use of muon spin rotation/relaxation. Our data
reveal that the samples enter into a 2D spin-glass state below TSG=12 K. We
further show that lithium diffusion channels become active for T>Tdiff=125 K
where the Li-ion hopping-rate [nu(T)] starts to increase exponentially.
Further, nu(T) is found to fit very well to an Arrhenius type equation and the
activation energy for the diffusion process is extracted as Ea=100 meV.Comment: Submitted to Journal of Physics: Conference Series (2014
