Zn‐In Alloying Powder Solvent Free Electrode Toward High‐Load Ampere‐Hour Aqueous Zn‐Mn Secondary Batteries (Small 17/2024)

Zn‐In Alloying Powder Solvent Free Electrode Toward High‐Load Ampere‐Hour Aqueous Zn‐Mn Secondary Batteries (Small 17/2024)

Aqueous Zn‐ion Batteries Indium surface‐modified Zn powders are utilized in a pilot‐scale solvent‐free electrode process (SFE@In), resulting in the formation of a 3D Zn deposition network with uniformly distributed electric field. This approach enables the fabrication of soft‐packaged batteries that...

Zusammenfassung:Aqueous Zn‐ion Batteries Indium surface‐modified Zn powders are utilized in a pilot‐scale solvent‐free electrode process (SFE@In), resulting in the formation of a 3D Zn deposition network with uniformly distributed electric field. This approach enables the fabrication of soft‐packaged batteries that eliminates dendrite short‐circuiting and hydrogen evolution. The battery exhibits remarkable stability, maintaining over 200 cycles at the assembled 2.4 Ah level. More in article number 2308541, Haitao Zhou and co‐workers.
