Grinding Cost Analysis. According to the relevant data analysis, grinding mill has an impact on grinding cost and performance, accounted for 30 in overall mineral operating costs, accounted for 50 in whole grinding cost, so the grinding mill has a great influence on manufacturing operating rates, total grinding efficiency and total operation cost.
Such a small volume change in chargedischarge reaction may give another explanation for the high-rate capability but is quite surprising, considering much larger ionic radius of Na than that of Li . Indeed, the V 17.6 in Na x FePO 4 has been reported to be much larger than V 6.9 in Li x FePO 4 refs 9, 27.
