High power asymmetric supercapacitor based on activated carbon/reduced graphene oxide electrode system
Dywili, Nomxolisi; Ntziouni, Afroditi; Ndipingwi, Miranda M.; Ikpo, Chinwe; Nwanya, Assumpta C.; Kordatos, Konstantinos; Iwuoha, Emmanuel (Elsevier, 2023-02-22)We synthesized Graphene oxide (GO) using the modified Hummers method and further reduced to reduced graphene oxide (rGO) using hydrazine monohydrate and ammonia solution. The prepared materials were interrogated using ... -
High stability asymmetric supercapacitor cell developed with novel microwave-synthesized graphene-stabilized ruthenium antimonide nanomaterial
Ekwere, Precious; Ndipingwi, Miranda; Ikpo, Chinwe; Yussuf, Sodiq; Nwambaekwe, Kelechi; Uhuo, Onyinyechi; Iwuoha, Emmanuel (Elsevier, 2023-02-06)Ruthenium antimony oxide (RuSbO), and ruthenium antimony oxide graphene (RuSbO-G) nanomaterial was synthesized via the microwave-assisted method for the first time and tested as a possible electrode material for an asymmetric ...
