Sodium‐ion batteries (SIBs) are now being actively developed as low cost and sustainable alternatives to lithium‐ion (LIBs) for large‐scale electric energy storage applications. In recent years, various inorganic organic Na compounds, mostly mimicked from their Li counterparts, have been synthesized tested SIBs, some of them indeed demonstrate comparable specific capacity the presently LIB electrodes. However, lack suitable cathode materials is still a major obstacle commercial development...
As an anode material for sodium-ion batteries (SIBs), hard carbon (HC) presents high specific capacity and favorable cycling performance. However, cost low initial Coulombic efficiency (ICE) of HC seriously limit its future commercialization SIBs. A typical biowaste, mangosteen shell was selected as a precursor to prepare low-cost high-performance via facile one-step carbonization method, the influence different heat treatments on morphologies, microstructures, electrochemical performances...
Abstract The short cycle life and safety concerns caused by uncontrollable dendrite growth have severely hindered the commercialization of lithium metal batteries. Here, a polycationic hydrophobic polymer protective layer fabricated scalable tape‐casting method is developed to enable air‐stable, dendrite‐free, highly efficient Li anodes. polymeric cations poly(diallyl dimethyl ammonium) (PDDA) provide an electrostatic shielding effect that unifies + flux at surface anode promotes homogeneous...
Abstract P2‐type Na 2/3 Ni 1/3 Mn O 2 (NNMO) has been investigated as one of the promising cathode materials sodium‐ion batteries (SIBs) due to a low‐cost and wide‐temperature‐range adaptability. However, its application faces number obstacles because poor cycling stability bad rate capabilities. Herein, by accommodating more Na‐ions at e‐site (Na e ) in NNMO, which is thermodynamically stable, layered oxides /Na f > 1.64) with outstanding electrochemical performance are obtained....
Abstract Although sodium‐ion batteries (SIBs) are considered as alternatives to lithium‐ion (LIBs), the electrochemical performances, in particular energy density, much lower than LIBs. A metal–organic compound, cuprous 7,7,8,8‐tetracyanoquinodimethane (CuTCNQ), is presented a new kind of cathode material for SIBs. It consists both cationic (Cu II ↔Cu I ) and anionic (TCNQ 0 ↔TCNQ − ↔ TCNQ 2− reversible redox reactions, delivering discharge capacity high 255 mAh g −1 at current density 20 mA...

Abstract The electrochemical performances of lithium metal batteries are determined by the kinetics interfacial de‐solvation and ion transport, especially at low‐temperature environments. Here, a novel electrolyte that easily de‐solvated conducive to film formation is designed for batteries. A fluorinated carboxylic ester, diethyl fluoromalonate (DEFM), carbonate, fluoroethylene carbonate (FEC) used as solvents, while high concentrated bis(trifluoromethanesulfonyl)imide (LiTFSI) served...
Li-rich and Ni-rich layered oxides as next-generation high-energy cathodes for lithium-ion batteries (LIBs) possess the catalytic surface, which leads to intensive interfacial reactions, transition metal ion dissolution, gas generation, ultimately hinders their applications at 4.7 V. Here, robust inorganic/organic/inorganic-rich architecture cathode-electrolyte interphase (CEI) inorganic/organic-rich anode-electrolyte (AEI) with F-, B-, P-rich inorganic components through modulating frontier...
Prussian blue analogs (PBAs) with stable framework structures are ideal cathodes for rechargeable sodium-ion batteries. The chelating agent-assisted coprecipitate method is an effective way to obtain low-defect PBAs that can limit the appearance of too many vacancies and water molecules achieve optimized Na-storage performance. However, this method, mechanism synthesis still unclear. Herein, process nickel hexacyanoferrate (NiHCF) has been investigated by in situ infrared spectroscopy...
Hard carbons (HCs) are the most promising anode materials for potassium-ion batteries (PIBs) due to their low cost, diverse precursors, easy-to-design nature, and excellent electrochemical performance. However, relationships between structure K+ storage mechanism of HCs have not been clearly systematically investigated, while principles hard carbon design remain unclear. Here, a series with continuously adjustable synthesized at 800–2900 °C study structure–mechanism relationships. With...
Abstract Here, a P2‐type layered Na 2 Zn TeO 6 (NZTO) is reported with high + ion conductivity ≈0.6×10 −3 S cm −1 at room temperature (RT), which comparable to the currently best 1+ n Zr Si P 3− O 12 NASICON structure. As small amounts of Ga 3+ substitutes for 2+ , more vacancies are introduced in interlayer gaps, greatly reduces strong –Na coulomb interactions. Ga‐substituted NZTO exhibits superionic ≈1.1×10 RT, and excellent phase electrochemical stability. All solid‐state batteries have...
NaTi2(PO4)3 (NTP) with a sodium superionic conductor three-dimensional (3D) framework is promising anode material for sodium-ion batteries (SIBs) because of its suitable potential and stable structure. Although 3D structure enables high Na-ion diffusivity, low electronic conductivity severely limits NTP's practical application in SIBs. Herein, we report porous NTP/C nanofibers (NTP/C-NFs) obtained via an electrospinning method. The NTP/C-NFs exhibit reversible capacity (120 mA h g–1 at 0.2...
A novel solid sodium-ion conductor, Na2Mg2TeO6 (NMTO) with a P2-type honeycomb-layered structure, has been synthesized for the first time by simple solid-state synthetic route. The conductor of NMTO exhibits high conductivity 2.3 × 10–4 S cm–1 at room temperature (RT) and large electrochemical window ∼4.2 V (versus Na+/Na). is remarkably stable, both in ambient environment within its metallic Na anode. This facile displays potential use all-solid-state batteries (SS-SIBs).
Prussian blue analogs (PBAs) are attractive cathode candidates for high energy density, including long life-cycle rechargeable batteries, due to their non-toxicity, facile synthesis techniques and low cost. Nevertheless, traditionally synthesized PBAs tend have a flawed crystal structure with large amount of [Fe(CN)6]4- openings the presence water in framework; therefore specific capacity achieved has continuously been poor cycling stability. Herein, we demonstrate low-defect sodium-enriched...
Recently, carboxylate metal-organic framework (MOF) materials were reported to perform well as anode for lithium-ion batteries (LIBs); however, the presumed lithium storage mechanism of MOFs is controversial. To gain insight into LIBs, a self-supported Cu-TCNQ (TCNQ: 7,7,8,8-tetracyanoquinodimethane) film was fabricated via an in situ redox routine, and directly used electrode LIBs. The first discharge charge specific capacities are 373.4 219.4 mAh g-1 , respectively. After 500 cycles,...
