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.
Thanks to the designable structure of CONs, we believe that the colloid electrolyte featuring a multiscale structure paves a way to develop electrolytes for lithium metal batteries (LMBs) and other alkali-ion/metal batteries. Current electrolytes often struggle to meet the demands of rechargeable batteries under various working conditions.
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.
To address this, a colloid electrolyte consisting of Li 3 P nanoparticles uniformly dispersed in the RCE is developed by a one-step synthesis. This design concurrently creates stable cathode electrolyte interphase (CEI) and solid electrolyte interphase (SEI) on both electrode surfaces.
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.
Current electrolytes often struggle to meet the demands of rechargeable batteries under various working conditions. A general electrolyte design strategy that can cater to battery application scenarios is needed.
