Colloidal synthesis is a powerful synthetic strategy and has been successfully applied for controllably synthesizing tin-based nanomaterials. In this feature article, we have focused on the developments from our group in colloidal synthesis and application in batteries of tin-based materials.
Although our colloidal batteries are intended to operate in a large reservoir of electrolyte, there are other application scenarios where the microrobots are in a dry environment or where ionic species are not available in the liquid environment.
Here, the authors design a “beyond aqueous” colloidal electrolyte with ultralow salt concentration and inherent low freezing point and investigate its colloidal behaviors and underlying mechanistic principles to stabilize cryogenic Zn metal battery.
During the battery cycle process, factors such as the electric field effect and its constantly changing direction, ion concentration’s variations at the interface, and bulk phase of electrolyte can significantly influence both the stable state and motion behavior of colloidal particles.
The PVP-I colloid exhibits a dynamic response to the electric field during battery operation. More importantly, the water competition effect between (SO 4) 2– from the electrolyte and water-soluble polymer cathode materials establishes a new electrolyte/cathode interfacial design platform for advancing ultralong-lifetime aqueous batteries.
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.
