“…Hence, to obtain AC with characteristics that provide CE with the finest electrochemical properties, it is crucial to find optimum experimental conditions. Generally, the literature indicates that the ACs with the finest properties are produced at high-temperature pyrolysis [14][15][16][17][18] as a consequence of the aromatization process in the carbon chain (enabled at high temperature) [19][20][21]. Bouchelta et al [22] studied the effects of pyrolysis conditions on the porous structure of ACs made from date pits.…”

Cheap and efficient carbon electrodes (CEs) for energy storage systems (ESS) such as supercapacitors (SCs) and batteries are an increasing priority issue, among other things, due to a globally increasing share of intermittent electricity production (solar and wind) and electrification of transport. The increasing consumption of portable and non-portable electronic devices justifies research that enables environmentally and economically sustainable production (materials, processing techniques, and product design) of products with a high electrochemical performance at an acceptable cost. Among all the currently explored CEs materials, biomass-based activated carbons (AC) present enormous potential due to their availability and low-cost, easy processing methods, physicochemical stability, and methods for self-doping. Nitrogen doping methods in CEs for SCs have been demonstrated to enhance its conductivities, surface wettability, and induced pseudocapacitance effect, thereby delivering improved energy/power densities with versatile properties. Herein, a short review is presented, focusing on the different types of natural carbon sources for preparing CEs towards the fabrication of SCs with high electrochemical performance. The influences of ACs’ pore characteristics (micro and mesoporosity) and nitrogen doping on the overall electrochemical performance (EP) are addressed.

Sustainable Biomass Activated Carbons as Electrodes for Battery and Supercapacitors—A Mini-Review

et al. 2020

View full text Add to dashboard Cite

: Some recent developments in the preparation of biomass carbon electrodes (CEs) using various biomass residues for application in energy storage devices, such as batteries and supercapacitors, are presented in this work. The application of biomass residues as the primary precursor for the production of CEs has been increasing over the last years due to it being a renewable source with comparably low processing cost, providing prerequisites for a process that is economically and technically sustainable. Electrochemical energy storage technology is key to the sustainable development of autonomous and wearable electronic devices. This article highlights the application of various types of biomass in the production of CEs by using different types of pyrolysis and experimental conditions and denotes some possible effects on their final characteristics. An overview is provided on the use of different biomass types for the synthesis of CEs with efficient electrochemical properties for batteries and supercapacitors. This review showed that, from different biomass residues, it is possible to obtain CEs with different electrochemical properties and that they can be successfully applied in high-performance batteries and supercapacitors. As the research and development of producing CEs still faces a gap by linking the type and composition of biomass residues with the carbon electrodes’ electrochemical performances in supercapacitor and battery applications, this work tries to diminish this gap. Physical and chemical characteristics of the CEs, such as porosity, chemical composition, and surface functionalities, are reflected in the electrochemical performances. It is expected that this review not only provides the reader with a good overview of using various biomass residues in the energy storage applications, but also highlights some goals and challenges remaining in the future research and development of this topic.

“…Nos espectros estão delimitadas apenas as regiões e os picos correspondentes aos modos vibracionais dos grupos funcionais mais relevantes que evidenciaram modificações superficiais com os tratamentos realizados. Comparando os espectros FTIR, observa-se que a FCP-TQ e FCP-Q apresentaram alterações de alguns modos vibracionais comparada com a FCP, destacando a atenuação do sinal observada na região de 3.630 a 2.984 cm -1 resultante dos modos de estiramento dos grupos OH e de 1.720 a 1.540 cm -1 atrelado as vibrações de estiramento de C=O de ésteres e ácidos carboxílicos para a FCP-TQ [19][20][21][22][23][24]. Por outro lado, um aumento do sinal no espectro correspondente a esses modos vibracionais foi observado para a FCP, cujo aumento se atribui à oxidação química devido a uma maior quantidade de grupos OH e C=O formados, com a incorporação de uma quantidade maior de grupos carboxílicos a superfície da FCP.…”

Reciclagem de fibras de carbono oriundas de compósitos estruturais de matriz epóxi por processo térmico de pirólise e aplicação como materiais de eletrodo em supercapacitores

et al. 2021

RESUMO Compósitos poliméricos reforçados com fibras de carbono são materiais cada vez mais utilizados em diferentes segmentos industriais, em especial, os segmentos aeronáuticos e automobilísticos devido a sua elevada resistência mecânica e baixa massa específica. Desta forma, existe grande preocupação com o descarte e a reciclagem dos componentes que representam produtos de alto valor econômico agregado, principalmente fibras de carbono. O processo de pirólise tem sido um dos métodos de reciclagem de compósitos para recuperar as fibras de carbono a partir da degradação da matriz polimérica. No setor de energia, fibras de carbono são traduzidas como bons materiais de armazenamento de energia, por apresentar desejáveis características condutoras e capacitivas que potencializam sua aplicação como material de eletrodo em supercapacitores. Neste sentido, a proposta deste trabalho consiste em viabilizar o uso de fibras de carbono recicladas por pirólise de compósitos epóxi reforçado com fibras de carbono como material de eletrodo de supercapacitores e avaliar a influência dos tratamentos termoquímico e químico sobre suas propriedades capacitivas. Imagens FEG-MEV mostraram que as fibras de carbono foram praticamente limpas permanecendo um mínimo de carbono residual sobre a superfície. A área BET e as análises FTIR, Raman e de voltametria cíclica mostraram que os tratamentos termoquímico e químico realizados na FCP não contribuíram para melhorar a capacidade de armazenamento de cargas na interface eletrodo/eletrólito, pelo contrário, o tratamento químico levou a uma grande redução da capacidade da FCP no armazenamento de energia devido a incorporação de grupos OH e COOH. As curvas de carga/descarga evidenciam boa ciclabilidade e os valores de capacitância específica para a fibra de carbono reciclada de 34 Fg-1, densidade de potência de 37,6 Wkg-1 e densidade de energia de 4,7 Whkg-1encontram-se dentro da faixa para aplicações como eletrodos de supercapacitores.
