Abstract null null Prussian blue analogs (PBAs) with rigid open framework are promising low-cost and easily prepared cathodes for Na-ion batteries. However, their electrochemical performances are hindered from the crystal vacancies and interstitial water in a traditional aqueous co-precipitation process. Herein, we explore a solvent-free mechanochemical protocol to prepare a monoclinic Na1.94Mn[Fe0.99(CN)6]0.95·□0.05·1.92H2O via regulating the crystal water in precursors. The interstitial water ...

Abstract null null Inorganic solid-state electrolytes (ISSEs) are expected to achieve the application of lithium (Li) metal batteries. However, Li metal can still cause internal short circuit in solid electrolyte. Direct evidence is lacked to show how Li dendrites penetrate the solid electrolytes. Herein, an in-situ mini cell has been set up to study the behavior of Li growth inside garnet-type electrolyte. Transparent Li6.4La3Zr1.4Ta0.6O12 (LLZTO) pellets are prepared and employed in the in-sit...

Abstract null null The low ionic conductivity of solid-state electrolytes (SSEs) and the inferior interfacial reliability between SSEs and solid-state electrodes are two urgent challenges hindering the application of solid-state sodium batteries (SSSBs). Herein, sodium (Na) super ionic conductor (NASICON)-type SSEs with a nominal composition of Na3+2xZr2–xMgxSi2PO12 were synthesized using a facile two-step solid-state method, among which Na3.3Zr1.85Mg0.15Si2PO12 (x = 0.15, NZSP-Mg0.15) showed th...

Na-ion batteries (NIBs) have been considered as potential candidates for large-scale energy storage, where O3-type Na-based layered oxide cathodes have attracted great attention due to their high capacity and low cost. However, O3-NaxTMO2 materials still suffer from insufficient air stability, which could lead to deteriorative electrochemical properties and thus hinder their practical application. In this work, a series of Al-doped O3-NaFe(1/3-x)Ni1/3Mn1/3AlxO2 cathodes prepared by a co-precipit...

NASICON- (Na superionic conductor-) based solid-state electrolytes (SSEs) are believed to be attracting candidates for solid-state sodium batteries due to their high ionic conductivity and prospectively reliable stability. However, the poor interface compatibility and the formation of Na dendrites inhibit their practical application. Herein, we directly observed the propagation of Na dendrites through NASICON-based Na3.1Zr2Si2.1P0.9O12 SSE for the first time. Moreover, a fluorinated amorphous ca...

Na-ion batteries have been considered promising candidates for stationary energy storage. However, their wide application is hindered by issues such as high cost and insufficient electrochemical performance, particularly for cathode materials. Here, we report a solvent-free mechanochemical protocol for the in-situ fabrication of sodium vanadium fluorophosphates. Benefiting from the nano-crystallization features and extra Na-storage sites achieved in the synthesis process, the as-prepared carbon-...

Abstract Simultaneous enhancement in water flux and removal efficiency during the filtration process remains a big challenge for separation membranes. The porous structure of the filter paper can provide many channels for water transportation, but the separation performance is generally poor. The purpose of this study is to develop a new kind of filter paper consisting of ultralong hydroxyapatite (HAP) nanowires, cellulose fibers (CFs) and double metal oxide (LDO) nanosheets, and to achieve the ...

Abstract O3-type layered oxide materials are being considered as one of the most promising cathodes for Na-ion batteries owing to their higher capacity, however, they usually suffer from structural damage at the highly desodiated state. To achieve the stable/high-capacity O3-type Na-ion cathodes, a series of Ni-rich O3–Na[NixFeyMn1-x-y]O2 (x = 0.6, 0.7 and 0.8) oxide cathodes were successfully prepared and the phase transitions at high voltage were systematically investigated. Combined with the ...

Solid-state polymer electrolytes (SPEs) are proposed as promising candidates for application in sodium batteries to replace the organic liquid electrolytes for enhanced safety. In this study, we first verified the feasibility of PEO-NaPF6 SPE in solid-state sodium batteries (SSBs). The explored PEO-NaPF6 SPEs exhibit a relatively high ionic conductivity of ~6.3 × 10−4 S cm−1 at 80 °C, a large Na+ transference number (tNa+) of 0.58, and sufficient thermal stability at around 200 °C for SSBs.
