“…Nowadays, lithium-ion batteries are the most developed energy sources for modern portable electronics and their use in automotive application is also increasing [1,2,3,4,5,6,7,8]. So far, several materials, such as LiCoO 2 and LiMn 2 O 4 , have been used as cathode, but recently LiFePO 4 has attracted researchers’ interest due to its high specific energy, which may reach 580 Wh/kg, and relatively low production cost [9,10,11,12,13,14].…”
