Notes:
The rate capability of 18650 lithium-ion cells was studied in the paper. The experimentalresults showed that the reversible capacity declined to 89.5, 85.8 and 81.2% of the initial capacity after300 cycles at discharge rate of 0.5, 1 and 2C, respectively. The XRD and SAED analysis indicated that ata high current density partial positive electrode material LiCoO2 transformed gradually from well-layeredstructure to rock salt cubic crystal. Upon the cycling, the degradation of cathode materials’ structure andmuch thicker negative film on anode electrode surface contributed to the rate capability fade
