, Department of Chemical Engineering, Tsinghua University摘 要:Owing to their very high theoretical capacity,lithium(Li) metal anodes regain widespread..., the inherent bottleneck of Li metal anodes,especially the growth of Li dendrites and the related safety concerns, should be well addressed. Owing to their featured micro-/nano-porous structures......

difference for the anodes at different locations in the pit. The temperature in the upper anodes is higher than that in the lower anodes, and the temperature in the right anodes is higher than that in the left anodes, but the temperature difference is small relatively for a single anode. The low temperature zone gradually moves toward the flame flow direction during baking. The residual amount......
technologies.Achieving long cycle life and high energy density has been considered as important tasks for developing high-performance PIBs.The alloy-based anodes for PIBs have attracted great attentions because of their high theoretical capacity and relatively low operating voltage.In this review,the latest advance in the related alloy-based anodes was overviewed.Specifically,the correlations among......
apparatus was designed to improve the precision of overvoltage measurements. Anodes were doped with MgAl2O4 and AlF3 both by impregnation of the coke and by adding powder, and the measured overvoltage was compared with that of undoped samples. For prebake type anodes baked at around 1150 ℃, the anodic overvoltage was reduced by 40-60 mV, and for Soderberg type anodes, baked at 950 ℃, by 60-80 mV......
="ChDivSummary" name="ChDivSummary"><正> In this paper, the sintered Ti anodes (STA) with Ti suboxide intermediate layers and β-MnO2 activelayers were investigated in detail. At usual industrial current densities, the oxygen evolutionoverpotential on STA is reduced by 350 mV compared with lead anodes. According to the equationobtained experimentally, the service life of STA may be expected......
hydrothermal method and used as anodes for KIBs.Due to the advantages of SnS2/SnO2 heterostructures and good conductivity of SSM substrate,the SnS2/SnO2/SSM anodes display enhanced electrochemical performance.The SnS2/SnO2/SSM anodes deliver specific capacity of 394 mA h g-1 at 50 mA g-1 over 100 cycles,better than SnO2/SSM.Even at 500 mA g-1 after 250 cycles,high capacity of 155 mA h g-1 can......
