Sreenivas Jayanti,Ravendra Gundlapalli,Raghuram Chetty,C. R. Jeevandoss,Kothandaraman Ramanujam,Dayadeep S. Monder,Raghunathan Rengaswamy,P. V. Suresh,K. S. Swarup,U.V. Varadaraju,Vasu Gollangi,L. Satpathy +11 more
TL;DR: In this article, the characteristics of an indigenously developed 1 kW VRFB stack of two designs are presented, and important characteristics of interest to a design engineer such as materials of construction, cell sizes, operating conditions, power, charge/discharge capacity, energy efficiency and cycling behaviour are reported.
Journal ArticleDOI
A novel hierarchical porous activated carbon-organic composite cathode material for high performance aqueous zinc-ion hybrid supercapacitors
TL;DR: In this article , a hierarchical porous activated carbon with redox-active organic materials was used as an active hybrid cathode material for ZIHSCs, which exhibited an outstanding energy output of 250 Wh kg−1 @ 0.1 A g−1.
Journal ArticleDOI
Nitrogen-Doped High Surface Area Porous Carbon Material Derived from Biomass and Ionic Liquid for High-Performance Supercapacitors
TL;DR: In this article , high surface area, porous activated carbons (ACs) are synthesized from dried Sterculia foetida (SF) fruit shells via KOH activation.
Journal ArticleDOI
