Summary: This study explores the potential of layered boride materials (MoAlB and Mo2AlB2) as high-performance electrode materials for lithium-ion batteries (LIBs) and sodium-ion batteries (SIBs). It is found that Mo2AlB2 exhibits a higher specific capacity than MoAlB in LIBs, achieving a specific capacity of 593 mAh g(-1) after 500 cycles at 200 mA g(-1). Surface redox reactions are identified as the key mechanism for Li storage in Mo2AlB2. Additionally, sodium hydroxide treatment of MoAlB leads to a porous morphology and higher specific capacities in SIBs, with Mo2AlB2 exhibiting a specific capacity of 150 mAh g(-1) at 20 mA g(-1). These findings suggest the potential of layered borides as electrode materials for both LIBs and SIBs, emphasizing the importance of surface redox reactions in Li storage mechanisms.

Summary: Layered cathode materials, such as LiCoO2, have been synthesized for Li-ion batteries using a direct solution-calcination strategy. The addition of polyvinylpyrrolidone (PVP) as a functional agent in the synthesis process helps to eliminate surface Li residues and promote a uniform particle distribution. The solution-calcined cathode material shows improved cycling stability and rate capability compared to commercial LCO, with suppressed phase transition. This research provides a simple and versatile method for the synthesis of cathode materials, avoiding complicated steps and the formation of unwanted residual lithium compounds.

Summary: Through material modification, the commercial polypropylene separator is successfully modified with a cationic covalent organic framework (COF-F@PP), which has abundant nanopores to homogenize the lithium ions flux and can interact with electrolyte solvent molecules to form a desolvation structure of Li+. The F- within the nanopores helps to build a robust LiF-riched solid electrolyte interphase to avoid side reactions between the lithium anode and electrolyte. Therefore, COF-F@PP exhibits excellent cycling stability, high Coulombic efficiency, and superior rate capability in Li//LFP coin cell at 5 C, low N/P ratio (2.19) full cell, and pouch cell at 1 C.
