Dual electrode-free Zn-MnO2 battery as a future energy source

Aqueous rechargeable Zn-MnO2 batteries are considered one of the most promising energy storage systems and have been extensively studied in recent years, owing to their high energy density, low cost, and intrinsic safety. However, the practical application of conventional Zn-MnO2 batteries is hindered by poor cycling stability, corrosion, and unwanted side reactions. Recently, dual electrode-free …

Topological Insulator Bi2Te3 Anode for Aqueous Aluminum-Ion Batteries: Unveiling the Role of Hydronium Ions

The primary scientific challenge in advancing aqueous aluminum-ion batteries (AAIBs) is achieving reversible plating/stripping of the Al metal anode, limited by its low deposition potential (−1.667 V vs SHE) and surface passivation in the aqueous electrolyte. To address this issue, polypyrrole (PPy) decorated topological quantum insulator (Bi2Te3@PPy) is introduced as a novel anode in AAIBs. …

Flexible aqueous Zn–S battery based on an S-decorated Ti3C2Tx cathode

Flexible aqueous zinc-ion batteries can store energy safely and at a low cost, which benefits wearable electronic gadgets; however, currently used cathodes restrict these devices with a low specific capacity and energy density. Herein, we developed a flexible zinc-sulfur (Zn–S) battery constructed by Ti3C2Tx decorated with sulfur (S@Ti3C2Tx) as a cathode and Zn metal anode …
