Abstract
, and prom-ising electrochemical performance. This single-carbon-coating material was composed of micrometer-scale secondary parti-cles containing nanoscale carbon-coated primary particles; this morphology provided interconnected open pores that favor elec-trolyte absorption and signifi cantly reduce the diffusion path of the lithium ions. This feature, combined with the high tap density, resulted in electrodes having high volumetric energy density and rate capability. Here we report a double coating process that greatly improves the uniformity of the carbon coating on both the primary and secondary LiFePO
