Abstract

Ideal solid electrolyte interphase (SEI) is required for non-dendrite lithium (Li) deposition of lithium metal batteries (LMBs). However, the spontaneously-formed SEI is non-homogenous in the composition and structure and thus cause oriented distribution of Li+ flux, which leads to the detrimental formation of lithium dendrites and poor cyclability of batteries. Here we propose a vertical & lateral ion-flux modulated ion-conductive SEI for high-voltage Li-metal batteries. A fluorinated MCM-41 (FMCM-41) modified LiPF6 electrolyte is designed to construct the SEI film, which consists of homogenously distributed LiF and LixSiOy, to regulate Li+ transport paths in the lateral and the vertical direction, respectively, achieving uniform lithium plating. With the FMCM-41 modified electrolyte, the prepared Li||Li cell presents a long-term stability over 1000 h, and the Li||NCM622 full cell exhibits outstanding cycling performance with a high specific capacity of 169.9 mAh g-1 and a high-capacity retention of 93.3 % over 100 cycles at 0.5 C. This lateral-vertical concept provides a promising strategy for designing a desired SEI with uniform Li+ transport paths to achieve ultra-long and high-rates lithium metal batteries.

用于高性能锂金属电池的垂直和横向离子通量调制离子导电SEI
理想固体电解质间相(SEI)是锂金属电池非枝晶锂沉积的必要条件。然而,自发形成的SEI在组成和结构上不均匀,导致Li+通量定向分布,不利于锂枝晶的形成,电池的可循环性较差。这里我们提出一个垂直的&;高压锂金属电池用横向离子通量调制离子导电SEI。设计了一种氟化MCM-41 (FMCM-41)修饰的LiPF6电解质,构建由均匀分布的LiF和LixSiOy组成的SEI膜,分别调节Li+在横向和垂直方向的输运路径,实现均匀的锂电镀。利用FMCM-41改性的电解液,制备的Li||锂电池具有超过1000 h的长期稳定性,而Li||NCM622全电池具有出色的循环性能,其比容量高达169.9 mAh g-1,在0.5 c下100次循环时的高容量保持率为93.3%。这种横向垂直概念为设计具有均匀Li+传输路径的理想SEI提供了一种有希望的策略,从而实现超长和高倍率的锂金属电池。
