Aqueous lithium-ion batteries (ALIBs) hold promise of providing cost-effective and safe energy storage in the context an increasingly environmentally aware narrative. Moreover, mitigating concerns surrounding critical raw materials present traditional LIBs reinforces alignment with such ideals. Herein, we delve into electrochemistry perylene-3,4,9,10-tetracarboxylic acid di-imide (PTCDI) evaluate its potential as organic anode active material for ALIBs. We find all-organic to very reversibly...
Abstract Modern batteries are highly complex devices. The cells contain many components—which in turn all have variations, both terms of chemistry and physical properties. A few examples: the active materials making electrodes coated on current collectors using solvents, binders additives; multicomponent electrolyte, contains salts, electrolyte can also be a solid ceramic, polymer or glass material; separator, which made fibres, polymeric, composite, etc. Moving up scale these components...
The hydrogen evolution reaction (HER) has been widely demonstrated to have a strong dependence on pH and the source of protons, where clear kinetic advantage arises in acidic conditions over near-neutral alkaline due switch reactant from H3O+ H2O. Playing acid/base chemistry aqueous systems can avoid frailties. For example, buffer be used maintain proton concentration at intermediate pH, driving reduction In light this, we examine influence amino acids HER kinetics platinum surfaces using...
This study investigates a salt design principle for aqueous battery electrolytes by combining chaotropic ions, guanidium cations (Gdm) and bis(trifluoromethanesulfonyl)imide anions (TFSI), forming GdmTFSI. salt's crystal structure was solved via single-crystal X-ray diffraction characterized using Fourier-transform infrared spectroscopy. Study reveals that GdmTFSI disrupts the hydrogen bonding network of solutions, impacting water reactivity at electrochemical interfaces.

Electrolyte engineering has been key to the advancement of aqueous lithium-ion batteries (ALIBs), for example, introduction water-in-salt electrolytes (WiSEs) enabled ALIBs cycle well and operate at potentials far beyond electrochemical stability window water. WiSEs are, however, intrinsically based on high concentrations salt(s) which furthermore often are expensive fluorinated, therefore defeats aim being low-cost sustainable. Strategies circumvent this issue have add co-solvents and/or...
