ABSTRACT
This category of iron-based compounds are naturally abundant and inexpensive and compared to vanadium, cobalt, and nickel compounds are more environmentally friendly (Laffont et al, 2006).
In this work we investigate a combination cathode of two olivine structured materials, each of them having a general formulae LiMPO4; where M = Fe, Mn, are of identical or different compositions (Fe and Mn contents), prepared under different conditions and having different characteristics. The aim is to study possible improved energy storage performances of combination cathode as compared to its individual materials. Here the first material A is a commercially available material and the second material B is produced by high energy ball milling in our laboratories. The weight fraction of B in the A+B mixture can range between 5% and 95%. In this paper the results of in house/ commercial powder ratio of 40/60 is demonstrated and the battery electrochemical performance of mixed and individual olivine materials is compared.
