Resumo: Supercapacitors are devices that accumulate electrical energy and have a long-life cycle, high power density and low weight. Despite these properties, they have low capacitance and energy density compared to other devices. To advance the applicability of supercapacitors, it is necessary to develop electrode materials that store a greater amount of energy. With the objective of analyzing the electrochemical properties of new materials applied in supercapacitors. Supercapacitors based on graphene oxide (GO) and reduced graphene oxide (RGO) were developed in this work. GO and RGO morphologies were analyzed by scanning electron microscopy (SEM) and chronoamperometry (AC) and cyclic voltammetry (VC) tests to evaluate the electrochemical performance of supercapacitors. The SEM test results showed that the GO used in the experiment had a porous structure and low crystallinity. According to the test results both supercapacitors have similar capacitance characteristics.

Apesar dessas propriedades, eles possuem baixa capacitância e densidade de energia em comparação com outros dispositivos. Para avançar na aplicabilidade dos supercapacitores, é necessário desenvolver materiais de eletrodos que armazenem uma quantidade maior de energia. Com o objetivo de analisar as propriedades eletroquímicas de novos materiais aplicados em supercapacitores. Supercapacitores baseados em óxido de grafeno (GO) e óxido de grafeno reduzido (RGO) foram desenvolvidos neste trabalho. As morfologias de GO e RGO foram analisadas por microscopia eletrônica de varredura (MEV) e testes de cronoamperometria (AC) e voltametria cíclica (VC) para avaliar o desempenho eletroquímico dos supercapacitores. Os resultados do teste de MEV exibiram que o GO usado no experimento tinha uma estrutura porosa e baixa cristalinidade. De acordo com os resultados do teste ambos os supercapacitores têm características de capacitância semelhantes.Universidade Federal de Viçosa - UFV2023-02-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArtigo, Manuscrito, Eventosapplication/pdfhttps://periodicos.ufv.br/jcec/article/view/1541710.18540/jcecvl9iss1pp15417-01eThe Journal of Engineering and Exact Sciences; Vol. 9 No. 1 (2023); 15417-01eThe Journal of Engineering and Exact Sciences; Vol. 9 Núm. 1 (2023); 15417-01eThe Journal of Engineering and Exact Sciences; v. 9 n. 1 (2023); 15417-01e2527-1075reponame:The Journal of Engineering and Exact Sciencesinstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/jcec/article/view/15417/7830Copyright (c) 2023 The Journal of Engineering and Exact Scienceshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessIsidorio, Daysianne Kessy MendesMagalhães, Matheus Emerick dePereira Júnior, Antonio Augusto MartinsFonseca, Clícia Joanna NevesMarchi, Belayne ZaniniOliveira, Pablo Henrique AtaídeAraújo, Filipe de AlmeidaAltoé, Leandra2023-02-24T18:44:16Zoai:ojs.periodicos.ufv.br:article/15417Revistahttp://www.seer.ufv.br/seer/rbeq2/index.php/req2/oai2527-10752527-1075opendoar:2023-02-24T18:44:16The Journal of Engineering and Exact Sciences - Universidade Federal de Viçosa (UFV)false
