Hydro-Québec and the U.S. Army Research Laboratory (ARL) have used Cr, Fe and Si to improve the performance of olivine LiCoPO 4 in cathodes for lithium-ion batteries. In a paper in the Journal of Power Sources , they report that a substituted-LiCoPO 4 in a half cell delivered a reversible capacity of 125?mAh/g at C/3 rate, with no capacity loss after over 100 cycles at 25?
