Is starch gel a cost-effective electrolyte for flexible Zn-air batteries?

Here, we report a cost-effective starch gel fabricated through the starch gelation reaction for flexible Zn-air batteries. Benefiting from excellent hydrophilicity and adhesion, the prepared starch gel electrolyte exhibits a high ionic conductivity of 111.5 mS cm−1, leading to the close contact between the electrolyte and the electrodes.

Can starch trap Zn-i 2 batteries?

Herein, we propose a structure confinement strategy to trap the polyiodide, endowing shuttling-free Zn–I 2 batteries by using a cheap natural biopolymer host of starch. It is widely acknowledged that starch turns bluish-violet when encountering iodine.

Are starch-based electrolyte systems suitable for lithium-ion batteries application?

Li-ion conductivity values related to the different nanoparticles and cross-linkers incorporated starch polymer electrolyte systems doped with various lithium salts. Starch-based electrolyte systems for the application of lithium-ion batteries application are highlighted owing to their intriguing properties, non-toxic and biodegradable in nature.

Does starch interact with iodine during battery operation?

These results highlight that the starch has a strong bonding interaction with iodine species during the battery operation, which leads to shuttle-free and highly reversible I − /I 2 conversion. The relationship between shuttling polyiodide and the corrosion of Zn anodes in Zn–I 2 batteries was studied.

Does starch confinement enhance i 0 / i conversion efficiency in zinc iodine batteries?

Zhao, D. et al. Enhancing I 0 /I − conversion efficiency by starch confinement in zinc–iodine battery. Energy Environ. Mater. 7, e12522 (2024). Liu, M. et al. Physicochemical confinement effect enables high-performing zinc–iodine batteries. J. Am. Chem. Soc.144, 21683–21691 (2022).

Why do starch based polymer electrolyte membranes change in a starch host?

The modifications in the starch host due to the interactions between SiO 2 nanoparticles, Li-ions, and starch polymer chains during the preparation of starch-based polymer electrolyte membranes.
