Unlocking ion Storage Chemistry in Aqueous Batteries via Operando Smartphone Multispectral Techniques

Peng Sun,
Zhong Ji,
Meijia Qiu
et al.

Abstract: Real‐time monitoring of the dynamic charging process and state‐of‐charge inside energy storage systems is crucial for ensuring their sustainable operation. Here, a novel computational multispectral imaging reconstruction (MSIRC) strategy is presented using a smartphone for in situ monitoring of the optical states of aqueous batteries via transparent monitoring window, allowing analysis of ion storage chemistry and real‐time capacity variations. Prussian blue and MnO2 that exhibit significant and subtle color c… Show more

“…10d , by leveraging the relative reflectance values at specific wavelengths, a “layer to layer” Zn 2+ storage mechanism and excessive Zn 2+ insertion was identified. 280 Researchers used a smartphone to perform the in situ analysis of aqueous batteries through a transparent monitoring window. The authors extracted the optical characteristics of the materials using computational reconstruction methods, thereby enabling the monitoring of the chemical ion storage and real-time capacity changes of the materials.…”
