Volume 27, Issue 11, 15 November 2024, 111229 Current solid- and liquid-state electrode materials with extreme physical states show inherent limitation in achieving the ultra-stable batteries. Herein, we present a colloidal electrode design with an intermediate physical state to integrate the advantages of both solid- and liquid-state materials.
The integration potential of the aqueous Zn||PEG/ZnI 2 colloid battery with a photovoltaic solar panel was demonstrated by directly charging the batteries in parallel to 1.6 V vs. Zn/Zn 2+ using a photovoltaic solar panel (10 V, 3 W, 300 mA) under local sunlight. The batteries were then connected in series to power an LED lamp (12 V, 1.5 W).
The constructed aqueous Zn||PEG/ZnI 2 colloid battery demonstrated ultra-stable cycling performance with Coulombic efficiencies approaching 100% and a capacity retention of 86.7% over 10,700 cycles, without requiring anodic modification.
The colloidal electrode was designed based on the inherent water competition effect of (SO 4) 2− from the aqueous electrolyte and inherently water-soluble polyethylene glycol (PEG)/ZnI 2 from the cathode.
However, capacity loss and low Coulombic efficiency resulting from polyiodide cross-over hinder the grid-level battery performance. Here, we develop colloidal chemistry for iodine-starch catholytes, endowing enlarged-sized active materials by strong chemisorption-induced colloidal aggregation.
The colloidal IS-based Zn-IS FBs with polypropylene (PP) membranes as LPPM could deliver superior performance of cycling stability for 350 cycles at high current density. In addition, due to the strong chemisorption between starch and iodine redox, the as-developed colloidal IS systems remained stable.
