Investigations of rate limitation in nanostructured composite electrodes and experiments towards a 3D Li-ion microbattery
The factors effecting discharge rate limitation within LiFePO4 composite electrode structures have been investigated. It was found that for composite electrodes containing ‘small particles’ of active material solid state processes are not necessarily rate limiting. A simple model has been developed …
