Lithium battery: Lithium battery is a kind of battery with lithium ion as the main medium. They typically consist of lithium metal oxides (such as lithium lithium cobaltate) as the positive electrode material, carbon materials (such as graphite) as the negative electrode material, and use lithium salts in organic solvents as the electrolyte.
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.
Remarkably, application of colloid electrolytes in proton batteries is found to result in significantly extended battery cycle life from limited tens-of-hours to months. 2. Results and discussions We first tested the MnO 2 /Mn 2+ electrolysis (3-electrode configuration, Fig. S4a) under increasing acid concentrations.
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.
The enhancements are attributed to improved anode stability, cathode efficiency and stabilized charge compensation in colloid electrolytes. Furthermore, the colloid electrolytes also show possibilities for applications in flow batteries.
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.
The soft, colloidal electrode material was realized through an inherent water competition effect between the (SO 4) 2– species from the aqueous electrolyte and inherently water-soluble polyethylene glycol (PEG)/ZnI 2 from the cathode, forming an aqueous Zn||PEG/ZnI 2 colloid battery (Figure 1 A).
