Incorporating Al<sup>3+</sup> within α-Ni(OH)<sub>2</sub> nanosheets provides higher capacity in Ni–Zn cells with phase stability upon cycling compared to the other tested divalent substituents and unsubstituted α-Ni(OH)<sub>2</sub>.
Rechargeable zinc–air batteries require air cathodes that support efficient electrocatalysis of both oxygen reduction and evolution. Electrocatalysts synthesized from abundant, low-cost elements with low-risk supply chains, such as the oxides hydroxides manganese, iron, nickel, are necessary to enable large-scale adoption technology. However, materials often underperform their cobalt-containing counterparts when required act bifunctional catalysts. Using two distinct sustainable...
Cation-defective iron oxides have proven to be effective Li-ion charge-storage hosts in nonaqueous electrolytes, particularly when expressed disordered, nanoscale forms such as aerogels. Replacing a fraction of Fe sites ferrites with high-valent cations V5+ introduces cation-vacancy defects that increase capacity. Herein, we show compositional substitution electroinactive Al3+ further increases capacity by 30% incorporated within disordered VFe2Ox aerogel, verified electrochemical tests...
Towards the goal of decarbonizing electrification, concerns remain over sustainability requisite Li and Co, as well stringent transportation limits on amount operational state allowed in airfreight. Rechargeable zinc-based batteries using aqueous electrolyte offer a compelling alternative to lithium-based with added benefit two-electron anode that augments energy density, helping compensate for lower cell voltage inherent electrolytes. To solve standing caveat rechargeable — they form...
