Hollow structured cathode materials for rechargeable batteries

“…For instance, the theoretical capacity of LiMnPO 4 is as high as isostructural LiFePO 4 , but the nearly insulating nature and the much lower Li mobility of LiMnPO 4 make the high capacity much less achievable [82]. To tackle the challenge, Fu et al [83] [84]). Researchers have devoted many efforts in improving the real performance of silicates.…”

Improved electrochemical performance of LiFe0.4Mn0.6PO4/C with Cr3+ doping

“…The electronic conductivity of LiMnPO 4 (<10 À10 S cm À1 ) is much lower in comparison with that of LiFePO 4 ($10 À8 S cm À1 ), 11,12 resulting in a much poorer electrochemical performance. There have been many efforts in recent years to increase the electronic conductivity of LiMnPO 4 by decreasing the particle size, [13][14][15][16] coating with electronically conducting agents, [17][18][19][20][21] or doping with cations such as Mg 2+ , Fe 2+ , Cu 2+ , Co 2+ , Ni 2+ , Ca 2+ and Zn 2+ . [22][23][24][25][26] Decreasing the particle size could reduce the transport distance of electrons and Liions, which can enhance the rate performance.…”
