Rapid-charging aluminium-sulfur batteries operated at 85 °C with a quaternary molten salt electrolyte

Nature Communications, Journal Year: 2024, Volume and Issue: 15(1)

Published: Jan. 18, 2024

Abstract Molten salt aluminum-sulfur batteries are based exclusively on resourcefully sustainable materials, and promising for large-scale energy storage owed to their high-rate capability moderate density; but the operating temperature is still high, prohibiting applications. Here we report a rapid-charging aluminium-sulfur battery operated at sub-water-boiling of 85 °C with tamed quaternary molten electrolyte. The alkali chloroaluminate melt – possessing abundant electrochemically active high-order Al-Cl clusters yet exhibiting low melting point facilitates fast Al 3+ desolvation. A nitrogen-functionalized porous carbon further mediates sulfur reaction, enabling excellent cycling stability 85.4% capacity retention over 1400 cycles charging rate 1 C. Importantly, demonstrate that asymmetric reaction mechanism involves formation polysulfide intermediates, as revealed by operando X-ray absorption spectroscopy, accounts high kinetics such wherein thermal management can be greatly simplified using water heating media.

Electropolymerized Bipolar Poly(2,3‐diaminophenazine) Cathode for High‐Performance Aqueous Al‐Ion Batteries with An Extended Temperature Range of −20 to 45 °C

Advanced Materials, Journal Year: 2024, Volume and Issue: 36(24)

Published: March 1, 2024

Abstract Achieving reversible insertion/extraction in most cathodes for aqueous aluminum ion batteries (AAIBs) is a significant challenge due to the high charge density of Al 3+ and strong electrostatic interactions. Organic materials facilitate hosting multivalent carriers rapid ions diffusion through rearrangement chemical bonds. Here, bipolar conjugated poly(2,3‐diaminophenazine) (PDAP) on carbon substrates prepared via straightforward electropolymerization method introduced as cathode AAIBs. The integration n‐type p‐type active units endow PDAP with an increased number sites interaction. long‐range skeleton enhances electron delocalization collaborates ensure conductivity. Moreover, intermolecular interactions including π–π interaction hydrogen bonding significantly enhance its stability. Consequently, Al//PDAP battery exhibits large capacity 338 mAh g −1 long lifespan high‐rate capability. It consistently demonstrates exceptional electrochemical performances even under extreme conditions capacities 155 348 at −20 45 °C, respectively. In/ex situ spectroscopy comprehensively elucidates cation/anion (Al /H 3 O + ClO 4 − ) storage 3‐electron transfer dual electroactive centers (C═N –NH–). This study presents promising strategy constructing high‐performance organic AAIBs over wide temperature range.
