Hydrothermal synthesis of reduced graphene oxide for supercapacitor electrode materials and the effect of added sodium alginate on its structure and performance

Synergistic effects of a copper–cobalt–nitroisophthalic acid/neodymium oxide composite on the electrochemical performance of hybrid supercapacitors

“…1 Due to their extended cycle life, and high power and energy density, researchers have focused on second-generation lithium-ion batteries, fuel cells, and supercapacitors as viable and sustainable energy-storage options. 2,3 In this regard, batteries and supercapacitors (SCs) are both essential for storing renewable energy. Batteries have a high energy density due to redox processes, but their power density is restricted compared to supercapacitors.…”
