Rechargeable aqueous aluminum batteries (AABs) are promising energy storage technologies owing to their high safety and ultra-high energy-to-price ratio. However, either the strong electrostatic forces between high-charge-density Al 3+ and host lattice, or sluggish large carrier-ion diffusion toward the conventional inorganic cathodes generates inf...

The strong electrostatic interaction between high‐charge‐density zinc ions (112 C mm ⁻³ ) and the fixed crystallinity of traditional oxide cathodes with delayed charge compensation hinders the development of high‐performance aqueous zinc‐ion batteries (AZIBs). Herein, to intrinsically promote electron transfer efficiency and improve lattice toleran...

Rechargeable aluminum batteries (RABs) with uniquely high energy-to-price ratio are promising energy storage systems. However, owing to the large-size active ions (e.g. AlCl4- and [AlCl2(urea)2]+) in state-of-the-art ionic-liquid RABs, the...

Due to the unique electronic structure of Al3+ with strong Coulombic interaction and complex bonding situation (simultaneously covalent/ionic bonds), traditional electrodes, mismatching with the bonding orbital of Al3+, usually exhibit slow kinetic process with inferior rechargeable aluminum batteries (RABs) performance. Herein, to break the confin...

Rechargeable aluminum batteries (RABs), with abundant aluminum reserves, low cost, and high safety, give them outstanding advantages in the postlithium batteries era. However, the high charge density (364 C mm⁻³) and large binding energy of three‐electron‐charge aluminum ions (Al³⁺) de‐intercalation usually lead to irreversible structural deteriora...

A novel electric field-assisted strategy to fabricate graphene oxide (GO)-functionalized nanofiltration (NF) membranes was reported. The resulting polyamide (PA) NF membranes were formed by interfacial polymerization (IP) of trimesoyl chloride (TMC) in an organic phase and piperazine as well as GO with a concentration between 0.1 and 0.5 in the wat...

A structurally controlled polyethersulfone (PES) membrane, as the substrate of the thin film composite nanofiltration (NF) membranes, was designed and fabricated with aligned carbon nanotubes (ACNTs) by a direct current electric field. The morphology and properties of the NF membranes were simultaneously affected by the PES substrate with especial...

Anatase titania anchored graphene oxide (TGO) and sodium ligninsulfonate (SLS) were introduced into chitosan (CS) proton exchange membrane (PEM) by solution casting to improve its mechanical strength, proton conductivity and selectivity. Herein, TGO, an association of proton conduction and enhancements, was fabricated by a facile one-step hydrother...

One‐dimensional (1D) sodium ligninsulfonate functionalized carbon nanotubes (SCNT), two‐dimensional (2D) graphene oxide (GO), and three‐dimensional (3D) zirconium‐based metal‐organic frameworks (UiO‐66) are self‐assembled as filler materials for proton‐exchange membranes (PEMs) because of their potential for extending proton transport pathways. Her...

Hybrid ultrafiltration membranes of poly(vinylidene fluoride) (PVDF) and poly(ethylene glycol)-multi-walled carbon nanotubes (PMWCNTs) have been prepared via phase inversion method. Compared with pristine PVDF membranes, PMWCNT/PVDF hybrid membranes showed a significant higher water flux (384 L m⁻² h⁻¹), more stable rejection rate of bovine serum a...

Graphene-based separation membrane exhibits great potential for the application of wastewater purification, but it is difficult to achieve a balance between water flux and rejection. To overcome the “trade-off” effect...

Anatase titania coated CNTs (TCNTs) and sodium lignin sulfonate (SLS) were introduced to chitosan membrane to improve the conductivity based on extra proton transfer channels built by TCNTs and sulfonate groups supplied by SLS. Water uptake, mechanical properties, oxidation stability and methanol-rejecting property of composite membranes were chara...

Carbon nanotubes (CNTs) were functionalized by a simple non-covalent modification with sodium lignosulfonate (SLS), and the hybrid polyethersulfone (PES) ultrafiltration membranes were prepared by phase inversion method with different ratios of functionalized carbon nanotubes (f-CNTs). SEM analysis indicated that obvious finger-like pores appeared...
