Summary: In this paper, a novel and environmentally friendly synthetic route of monodisperse CeF3 nanoparticles with high surface area was reported. The nanoparticles were synthesized through a surfactant-free aqueous precipitation route at room temperature, with a yield of approximately 90%. The nanoparticles were used to prepare for the first time 3D interconnected macroporous CeF3 materials. The characterization of these materials at different synthesis stages was conducted using various analysis techniques.

Summary: Disordered carbons have gained significant attention as promising anode materials for sodium ion batteries (SIBs) due to their widely-available sources and potential for high output voltage. However, the sodium storage mechanism in disordered carbons remains controversial. Recent studies suggest that the plateau region in disordered carbons is closely related to the embedding of sodium ions/semimetals in nanopores. This review comprehensively discusses the classification, characterization, and construction of nanopores, as well as provides future perspectives on the controllable construction of nanopores to enhance capacity and understand the Na storage mechanism.

Summary: In this study, a novel gel polymer electrolyte (PH@MOF polymer-based electrolyte [GPE]) was prepared by incorporating metal-organic framework (MOF) particles in a polymer matrix (polyvinylidene fluoride-hexafluoropropylene) to achieve high-performance sodium metal batteries (SMBs). The addition of MOF particles not only promoted the transfer of Na+ by reducing the movement hindrance of polymer chains, but also reduced polarization during electrochemical reactions by anchoring anions with their negative charge. The resulted GPE showed stable cycling performance with tiny overpotential for over 800 hours at a current density of 5 mA cm(-2), and the NVOPF|PH@MOF|Na cell exhibited impressive specific cycling capacity (113.3 mA h g(-1) at 1 C) and rate capability with considerable capacity retention.

Summary: It is found that carbonaceous hosts as cathodes in Li-Se batteries perform moderately, while metallic compounds with stronger chemical adsorption lead to rapid capacity decay. A ternary composite host, aTiO(2)/rTiO(2)/TiN@C, is designed to integrate good adsorption and rapid electron transport abilities, while introducing rutile to weaken overall adsorption. The resulting electrode exhibits good rate capability and cycling stability, making it a promising candidate for Li-Se batteries.

Summary: A strategy was proposed and realized for constructing the cathode-electrolyte interface (CEI) film using AlF3 as a cathode host in lithium-selenium batteries. A one-step method was employed to convert porous carbon containing Al particles (PC/Al) to layered AlF3 (PC/AlF3). The stable PC substrate with multidirectional channels alleviates volume expansion and improves electron conductivity. The uniform dispersion of AlF3 in PC exhibits strong chemical adsorption towards polyselenides. The constructed CEI film further serves as a blocked layer to prevent side reactions, resulting in a satisfying discharge capacity and long cycling stability.
