Conversion-type NiCoMn triple perovskite fluorides for advanced aqueous supercapacitors, batteries and supercapatteries.

Chemical communications (Cambridge, England)

Jia Z, Shi W, Ding R, Yu W, Li Y, Tan C, Sun X, Liu E.
PMID: 34286760
Chem Commun (Camb). 2021 Aug 10;57(64):7962-7965. doi: 10.1039/d1cc02488d.

Conversion-type NiCoMn triple perovskite fluorides (KNCMF-622) have been explored for advanced aqueous supercapacitors (ASCs), batteries (ABs) and supercapatteries (i.e., ASC/Bs). The ASC/Bs outperform the ASCs and ABs, owing to the synergistic effect of capacitive, pseudocapacitive and faradaic characteristics, showing...

A Broad-Spectrum Catalytic Amidation of Sulfonyl Fluorides and Fluorosulfates*.
