| 英文摘要 | Low areal density is a major barrier to power application of LiNi1/3Co1/3Mn1/3O2 for high capacity batteries. To obtain sustainable high C-rate discharging, new cell structures using expanded metal current collectors are studied for LiNi1/3Co1/3Mn1/3O2/graphite lithium ion battery. By adopting the expanded metal foil, the areal capacity of LiNi1/3Co1/3Mn1/3O2 cathodes is significantly increased for a wide range of discharging rates at both room and low temperature. At room temperature, the 10 C capacity of expanded metal cathode is 130.2 mAh g(-1), 43% higher than that of a conventional cathode, and at -10 degrees C the capacity increases nearly 100%. These can be ascribed to the decrease of interface impedance of the electrode as shown in EIS. Performance enhancement is observed for cells with expanded metal foils in place of conventional foils with LiNi1/3Co1/3Mn1/3O2 cathode and graphite anode. The full cell of expanded metals shows an areal capacity of 0.558 mAh cm(-2) at 10 C, 209.0% higher than conventional cells after 100 cycles. Scanning electron microscopy studies of expanded metal electrodes indicates the areal capacity can be improved further with coating process. The finding shows expanded metal electrodes can potentially be applied to other electrode materials which are suffering from capacity fade at high C-rates and at high loading densities.
