Abstract

Uneven lithium deposition, which leads to the growth of lithium dendrites, presents a significant challenge in the practical application of high-energy lithium metal batteries. Herein, we report a high specific surface area carbon cloth (CC@ZnO) with uniform dispersion of nano zinc oxide as a collector for lithium metal battery (LMB). The uniformly dispersed zinc oxide in the CC@ZnO helps to achieve consistent lithium nucleation and growth with its lithophility. The high specific surface area of the CC@ZnO can promote the nucleation and growth of metallic lithium inside the current collector, greatly alleviating the adverse effects of the hostless nature of the metallic lithium anode. By utilizing this three-dimensional composite carbon cloth as a collector in lithium metal batteries, the Coulombic efficiency of lithium deposition and stripping is improved. The Li–Cu asymmetrical battery achieved a Coulombic efficiency of 97.6% after 120 cycles at 3 mA cm^–2, with a deposition capacity of 3 mAh cm^–2 in an ether electrolyte without the addition of lithium nitrate.

高比面积复合碳布诱导锂内部生长以稳定锂金属阳极

锂沉积不均匀导致锂枝晶生长，是高能锂金属电池实际应用中的一个重大挑战。在此，我们报道了一种具有均匀分散的纳米氧化锌的高比表面积碳布（CC@ZnO）作为锂金属电池（LMB）的收集器。在CC@ZnO中均匀分散的氧化锌有利于锂的成核和生长。CC@ZnO的高比表面积可以促进集流管内金属锂的成核和生长，大大缓解了金属锂阳极无主性的不利影响。利用这种三维复合碳布作为锂金属电池的集热器，提高了锂沉积和汽提的库仑效率。在不添加硝酸锂的情况下，锂- cu不对称电池在3 mA cm-2下循环120次后，库仑效率达到97.6%，在乙醚电解质中沉积容量为3 mAh cm-2。
