Multifunctional Separator for Zn Metal Anode Protection

ECS Meeting Abstracts
Lithium-ion batteries (LIBs) have issues such as the high cost of raw materials due to the use of rare metals such as Li and Co in the electrode and the risk of fire due to the use of organic electrolytes.[1] Zn-ion batteries (ZIBs) based on aqueous electrolytes are inexpensive (~US$2 kg-1) and safe for practical use.[2] In addition, the high ...

Application of carbon materials for Zn anode protection in aqueous Zn metal batteries

Rare Metals
Abstract Aqueous Zn metal batteries (AZMBs) have gained widespread attention due to their high theoretical specific capacity, good safety, and low cost. Unfortunately, Zn anodes suffer from serious problems of dendrites and side reactions, which should be solved by modifying the Zn anode (Zn host, protective layer), electrolyte, and ...

Achieving Uniform Deposition of Zn with Amide Additives for Metal Anodes Stabilization

ACS Applied Materials & Interfaces
The practical applications of aqueous zinc-ion batteries (AZIBs) are hindered by detrimental effects such as dendrites formation at the Zn metal anode interface and parasitic side reactions induced by H2O. Hence, we propose adding amide additives to the Zn sulfate electrolyte (ZSO) to regulate the composition and properties of the electrolytes, thereby
