Abstract

In this work, a method of fabricating copper particles-modified LiFe0.95Mo0.05PO4 materials by a two-step chemical process is proposed. The structures and morphologies of the samples are characterized by XRD, SEM and XPS. The results demonstrate that Cu0 is the major valence of Cu element, and crystal structure of the electrode material isn't destroyed after distributing copper particles well on the surface of LiFe0.95Mo0.05PO4. Compared with LiFe0.95Mo0.05PO4, the samples containing Cu exhibit better initial discharge capacity of 143.6 mA h g−1 at 0.1 C and capacity retention of 96.6% after 60 cycles. The results indicate that the enhanced kinetics of electron and lithium-ion transport in the samples is attributed to the superficial copper particles.
