The as-synthesized LiMn0.7Fe0.3PO4/C delivered an excellent rate performance as a LiMnPO4 class of materials. Specifically, the specific discharge capacity was 164 mAh/g (96% of theoretical value) at the 0.05 C rate and 107 mAh/g at the 5 C rate (1 C = 170 mA/g). Electrochemical impedance spectroscopy (EIS) and galvanostatic intermittent titration technique (GITT) measurements indicated improvements in the transport of electrons and Li+ as well as the emergence of a single-phase region in lithium extraction and insertion reactions. © 2013 American Chemical Society.||Source Title:||ACS Applied Materials and Interfaces||URI:||http://scholarbank.nus.edu.sg/handle/10635/85276||ISSN:||19448244||DOI:||10.1021/am403991f|
