Scaling relation between renormalized discharge rate and capacity in NaxCoO2 films
Layered cobalt oxide, P2-NaxCoO2, is a prototypical cathode material for sodium-ion secondary battery. We systematically investigated the rate dependence of the discharge capacity (Q) in three thin films of Na0.68CoO2 with different film thickness (d) and in-plane grain radius (r). With subtracting...
