چکیده

Supercapacitors Translating the materials metrics of graphene into supercapacitor performance is critical but engineering capacitive energy storage challenging. In article number 2203761, Jinyou Shao and co-workers introduce a bubble-induced method for fabricating microspheres with high ion conductivity efficient utilization surface area, enabling stack supercapacitors to deliver density 83.4 Wh L−1, close that lead-acid batteries.

Zinc oxide nanoring embedded lacey graphene nanoribbons in symmetric/asymmetric electrochemical capacitive energy storage.

This article describes the synthesis and characterization of ZnO nanoring embedded graphene nanoribbons. Patterned holes (mesopore dia.) in graphene nanoribbons are chemically generated, leading to a high density of the edge planes. These planes carry negatively charged surface groups (like -COOH and -OH) and therefore anchor the metal ions in a cordial fashion forming a string of metal ions al...
