    Phosphorus‐Based Composites as Anode Materials for Advanced Alkali Metal Ion Batteries
    (Hoboke, NJ : Wiley, 2020) Zhou, Junhua; Shi, Qitao; Ullah, Sami; Yang, Xiaoqin; Bachmatiuk, Alicja; Yang, Ruizhi; Rummeli, Mark H.
    Alkaline metal ion batteries, such as lithium‐ion batteries have been increasingly adopted in consumer electronics, electric vehicles, and large power grids because of their high energy density, power density and working voltage, and long cycle life. Phosphorus‐based materials including phosphorus anodes and metal phosphides with high theoretical capacity, natural abundance, and environmental friendliness show great potential as negative electrodes for alkaline metal ion batteries. In this review, based on the understanding of the storage mechanism of alkali metal ions, the scientific challenges are discussed, the preparation methods and solutions to address these challenges are summarized, the application prospects are demonstrated, and finally possible future research directions of phosphorus‐based materials are provided.

    Dual‐Salt Electrolyte Additives Enabled Stable Lithium Metal Anode/Lithium–Manganese‐Rich Cathode Batteries
    (Weinheim : Wiley-VCH, 2021) Zhou, Junhua; Lian, Xueyu; Shi, Qitao; Liu, Yu; Yang, Xiaoqin; Bachmatiuk, Alicja; Liu, Lijun; Sun, Jingyu; Yang, Ruizhi; Choi, Jin-Ho; Rummeli, Mark H.
    Although lithium (Li) metal anode/lithium–manganese-rich (LMR) cathode batteries have an ultrahigh energy density, the highly active Li metal and structural deterioration of LMR can make the usage of these batteries difficult. Herein, a multifunctional electrolyte containing LiBF4 and LiFSI dual-salt additives is designed, which enables the superior cyclability of Li/LMR cells with capacity retentions of ≈83.4%, 80.4%, and 76.6% after 400 cycles at 0.5, 1, and 2 C, respectively. The dual-salt electrolyte can form a thin, uniform, and inorganic species-rich solid electrolyte interphase (SEI) and cathode electrolyte interphase (CEI). In addition, it alleviates the bulk Li corrosion and enhances the structural sustainability of LMR cathode. Moreover, the electrolyte design strategy provides insights to develop other high-voltage lithium metal batteries (HVLMBs) to enhance the cycle stability.
