The expansion and shrinkage characteristics of sulfur composite cathode electrode in rechargeable lithium batteries have been investigated. It was found that the sulfur composites electrodes expanded when discharging and shrank when charging again. The thickness change of the electrode was measured to be about 22%. The thickness of lithium metal anodes was also changed when lithium deposition and...
The charge/discharge characteristics of the sulfur composite cathodes were investigated at different temperatures and different current densities. The composite presented the discharge capacities of 854 and 632 mAh g−1 at 60 and −20 °C, respectively, while it had the discharge capacities of 792 mAh g−1 at 25 °C. The composite presented the discharge capacities of 792 and 604 mAh g−1 at 55.6 and 667 mA...
The charge and discharge characteristics of lithium batteries with sulfur composite cathodes have been investigated. The sulfur composites showed novel electrochemical characteristics. The analysis of the differential capacity indicated that the discharge process showed two voltage plateaus of 2.10V and 1.88V, and the charge process also presented two voltage plateaus of 2.22V and 2.36V. The overcharge...
The electrochemical behavior of the sulfur composite cathode material for rechargeable lithium batteries and the characteristic of the polyacrylonitrile precursor were investigated. The samples of different polyacrylonitrile precursors were characterized by thermogravimetric analysis, nuclear magnetic response, Fourier transform infrared spectrometer, and differential scanning calorimetry. The electrochemical...
