摘要
由于钠基双离子电池(Na-DIBs)的寿命较短,目前其经济可行且环保的实际应用受到了限制。开发坚固耐用的阴极-电解质间相(CEI)层有望成为提高钠基双离子电池循环性能的有效措施。在本文中,预循环过程中采用高充电电压来分解膨胀中碳微珠(HRO-MCMB)阴极表面上的二氟草酸硼酸钠(NaDFOB),从而促进富含无机物的 CEI 层的形成。这种 CEI 层不仅具有化学稳定性和机械强度,还能有效抑制阴极石墨层的体积膨胀和剥离。因此,用 0.02 M NaDFOB 修饰的 HRO-MCMB 阴极在电流密度为 1 C 的条件下循环 1000 次后,容量保持率达到 97.0%;HRO-MCMB(+)||HC(-)(HC = 硬碳)全电池在电流密度为 1 C 的条件下循环 300 次后,比容量保持在 110.9 mAh g-1 。总之,这项研究为高性能 Na-DIB 的实际开发提供了一种新策略。
In-Situ Implanted Robust and Durable Cathode-Electrolyte Interphase for High-Performance Sodium-Based Dual-Ion Batteries
The practical applications of economically viable and environmentally friendly sodium-based dual-ion batteries (Na-DIBs) are currently restricted because of the short life spans of these systems. The development of a robust and durable cathode–electrolyte interphase (CEI) layer is expected to serve as an effective measure to enhance the cycling performances of Na-DIBs. Herein, a high charging voltage is employed during precycling to decompose sodium difluoro(oxalato)borate (NaDFOB) on an expanded mesocarbon microbead (HRO-MCMB) cathode surface, thereby promoting the formation of an inorganic-rich CEI layer. This CEI layer not only serves as a chemically stable and mechanically strong barrier but also effectively inhibits the volume expansion and exfoliation of the cathode graphite layer. Consequently, the HRO-MCMB cathode modified with 0.02 M NaDFOB exhibited a capacity retention of 97.0% after 1000 cycles at a current density of 1 C. The HRO-MCMB(+)||HC(−) (HC = hard carbon) full cell maintained a specific capacity of 110.9 mAh g–1 after 300 cycles at 1 C. Furthermore, the Na-DIB full cell exhibited an impressive energy density of up to 422.6 Wh kg–1, and its maximum power density reached 4682.9 W kg–1. Overall, this study provides a novel strategy for the practical development of high-performance Na-DIBs.
