Nitish Kumar’s study explores nanoporous vanadium oxide in symmetric supercapacitor applications using organic electrolytes. The study synthesized VO2 (B) microflowers with a stable phase and tailored porous structures, utilizing block copolymers to achieve excellent supercapacitor performance.

The phase-optimized porous VO2 (B) microflowers (VM) were synthesized using a dual-templating co-assembly hydrothermal approach, utilizing PVP and F127 as structure-directing agents and as pore-directing templates, respectively. The unique structure and improved charge-transfer resistance for VO2 (B) microflowers help to achieve an energy density of 16.28 W h kg−1 for supercapacitor applications.
