Lithium Diffusion & Magnetism in Battery Cathode Material LixNi1/3Co1/3Mn1/3O2

We have studied low-temperature magnetic properties as well as high-temperature lithium ion diffusion in the battery cathode materials LixNi1/3Co1/3Mn1/1O2 by the use of muon spin rotation/relaxation. Our data reveal that the samples enter into a 2D spin-glass state below T-SG approximate to 12 K. We further show that lithium diffusion channels become active for T >= T-diff approximate to 125 K where the Li-ion hopping-rate [v(T)] starts to increase exponentially. Further, v(T) is found to fit very well to an Arrhenius type equation and the activation energy for the diffusion process is extracted as E-a approximate to 100 meV.
