Development of Li2FeSiO4/Activated Carbon Composited Cathodes for Li-Ion Capacitors
The Li2FeSiO4 is attractive as it not only displays outstanding electrochemical behavior, but it is also the basis for the explosion of substituted derivatives with improved properties. However, Li2FeSiO4 has low electronic and ionic conductivity. Carbon coating is an efﬁcient way to enhance the charge transfer. In this study, carbon coating was carried out by mixing Li2FeSiO4 with a carbon source followed by calcination at high temperature and atmospheric conditions. The Li2FeSiO4/carbon composites are denominated as LFSC1, LFSC2 and LFSC3. The pristine capacities of Li2FeSiO4/carbon composites are measure at different C rate. The LFSC2 shows the best performance at each C rate. The LICs are fabricated with lithium ion battery type anode and LFSC/activated carbon cathode. The performances are measured by battery test equipment with CC-CV charge/CC discharge procedure. The charge/discharge plots show the traditional diagram of supercapacitor. This work is studying by some other approach to achieve high power performance.
