摘要： Li 3 V 2 (PO 4 ) 3 C coreshell nanoparticles with typical sizes of 2040 nm were synthesized using a hydrothermal-assisted solgel method. Ascorbic acid and PEG-400 were adopted as carbon sources and reductants. The uniform Li 3 V 2 (PO 4 ) 3 C nanocomposite obtained was composed of a Li 3 V 2 (PO 4 ) 3 core with high-phase purity and a graphitized carbon shell, which was characterized using XRD, SEM, TEM, and Raman analysis. The nanocomposite exhibited a remarkably high rate capability and long cyclability, delivering a discharge capacity of 138 mA h g 1 at 5 C within a voltage range of 34.8 V and the capacity retention was 86% after 1000 cycles. The superior electrochemical performance of Li 3 V 2 (PO 4 ) 3 C indicates that it has potential for application as a cathode material in advanced rechargeable lithium-ion batteries. Li 3 V 2 (PO 4 ) 3 C coreshell nanoparticles, which were synthesized using a hydrothermal-assisted solgel method, show remarkable electrochemical performance when used as cathode materials for LIBs. 出版日期： 2013-06-27 識別號： ISSN: 2040-3364 識別號： EISSN: 2040-3372 識別號： DOI: 10.1039/c3nr01617j
