| 英文摘要 | The rational design of cathode hosts with superior polysulfide (ps) confinement properties, excellent li+/e(-) transport and improved cyclability is of the utmost importance for high-areal-capacity lithium-sulfur (li-s) batteries. herein, multi-functional nanowall arrays (mnwas) combining the aforementioned properties are fabricated to improve the electrochemical performance of li-s batteries with high areal sulfur loadings. the integrated conductive networks and top-down vertically aligned li+ transport channels are beneficial to li+/e(-) transport, resulting in high rate performance with a discharge capacity of 620 ma h g(-1) at a high current density of 9.6 ma cm(-2) for 4 mg cm(-2) sulfur-loaded s/mnwa electrodes. additionally, the strong ps shuttling suppression via the synergetic effects of physical confinement and chemical adsorption leads to li-s batteries with a sulfur loading of 10 mg cm(-2) capable of delivering a high areal capacity of 12.4 ma h cm(-2) with a high capacity retention of nearly 85% for over 100 cycles. what's more, the li-s batteries assembled with 4 mg cm(-2) sulfur-loaded s/mnwa electrodes show an ultra-low capacity decay of 0.07% per cycle over 400 cycles at 3.2 ma cm(-2). |
