Abstract
To tackle the issues of lithium sulfur battery (Li-S), a strategy of simultaneous regulating the band gap and catalytic activity of TiO2 via embedded MoO2 based on interlaced carbon nanotubes carrier as substrate material to achieve efficient adsorption has been proposed. This substrate material is controlled to be nanosized with abundant catalytically active sites and widely-distributed pore through the cross-linked porous conductive skeleton, further promoting the electrolyte penetration and charge transfer. In addition, the introduction of MoO2 tailors the Ti electronic states, so the substrate material renders high adsorption energy of −1.47 eV for Li2S6 by theoretical calculation. Furthermore, the cathode exhibits high conversion efficiency from long-chain lithium polysulfide to Li2S (Qlow/Qhigh (the conversion capacity of Li2S) is 2.91 at 0.1C) and excellent sulfur utilization and fast sulfur reaction kinetics. The cathode also exhibits a low-capacity fade and excellent cycling performance.
