dc.description.abstract | The pulverization of lithium metal electrodes during cycling recently has been suppressed through various techniques, but the issue of irreversible consumption of the electrolyte remains a critical challenge, hindering the progress of energy-dense lithium metal batteries. Here, we design a single-ion-conductor-based composite layer on the lithium metal electrode, which significantly reduces the liquid electrolyte loss via adjusting the solvation environment of moving Li+ in the layer. A Li||Ni0.5Mn0.3Co0.2O2 pouch cell with a thin lithium metal (N/P of 2.15), high loading cathode (21.5 mg cm(-2)), and carbonate electrolyte achieves 400 cycles at the electrolyte to capacity ratio of 2.15 g Ah(-1) (2.44 g Ah(-1) including mass of composite layer) or 100 cycles at 1.28 g Ah(-1) (1.57 g Ah(-1) including mass of composite layer) under a stack pressure of 280 kPa (0.2 C charge with a constant voltage charge at 4.3 V to 0.05 C and 1.0 C discharge within a voltage window of 4.3 V to 3.0 V). The rational design of the single-ion-conductor-based composite layer demonstrated in this work provides a way forward for constructing energy-dense rechargeable lithium metal batteries with minimal electrolyte content. The reactivity between lithium and a liquid electrolyte leads to degradation of a lithium metal battery, resulting in the depletion of the liquid electrolyte. Here, authors develop a composite layer that can mitigate the reactivity and consequently enable long-cycling lithium metal batteries. | - |
