“…Those mainly includes Fe-VI group materials (e.g., FeO, Fe 2 O 3 , Fe 3 O 4 , FeS, FeS 2 , FeSe, Fe (OH) 2 , and Fe(OH) 3 ), the metallic Fe 0 and other Fecontained compounds (e.g., ZnFe 2 O 4 , CuFe 2 O 4 , MnFe 2 O 4 , and FeF 3 ). [47][48][49][50][51][52][53][54][55][56][57][58][59][60] No matter the type of ferruginous species, the main electrochemical reaction involves the total or partial conversion between Fe-based anode material and Fe(OH) x /FeO x /Fe on the anode surface, as schematically shown in Figure 2A (bottom-left). To generally illustrate their charge storage mechanisms, we have taken the simplest Fe anode as a case example, and the typical cyclic voltammogram (CV) scan is shown (bottom-right in Figure 2A).…”

“…[47] Till now, considerable efforts have been devoted to exploiting manifold iron-based species as anodes for aqueous EES devices, including batteries and battery-supercapacitor hybrid devices. [52][53][54][55][56][57][58] However, challenges remain in addressing all the issues of iron anode with simple electrode design. In particular, the charge storage mechanism of iron anodes may be different in various aqueous EES devices, which gives rise to more specific issues that need to pay additional attention.…”

The ever-growing demands for green and sustainable power sources for applications in grid-scale energy storage and portable/wearable devices have enabled the continual development of advanced aqueous electrochemical energy storage (EES) systems. Aqueous batteries and supercapacitors made of iron-based anodes are one of the most promising options due to the remarkable electrochemical features and natural abundance, pretty low cost and good environmental friendliness of ferruginous species. Though impressive advances in developing the state-of-the-art ferruginous anodes and designing various full-cell aqueous devices have been made, there still remain key issues and challenges on the way to practical applications, which urgently need discussing to put forwards possible solutions. In this review, rather than focusing on the detailed methods to optimize the iron anode, electrolyte, and device performance, we first give a comprehensive review on the charge storage mechanisms for ferruginous anodes in different electrolyte systems, as well as the newly developed iron-based aqueous EES devices. The deep insights, involving the inherent failure mechanisms and corresponding modification/optimization strategies toward iron anodes for the development of high-performance aqueous EES devices, will then be discussed. The advances in applying iron-based aqueous EES devices for emerging fields such as flexible/wearable electronics and functionalized building materials will be further outlined. Last, future research trends and perspectives for maximizing the potential of current iron anodes and devices as well as exploiting brandnew iron-based aqueous EES systems are put forward.

“…Os sistemas de armazenamento por baterias fornecem reservas operacionais para o sistema de energia e ajudam na regulação de frequência e tensão. As baterias podem mudar o consumo de energia para tempos de produção de baixo custo ou emissões mais baixas para os usuários, que por sua vez gerenciam a produção de energia para tempos de preço mais altos [5] [6].…”

A crescente demanda energética mundial e os impactos ambientais acarretados pelo uso de combustíveis fósseis, além da estimativa que aponta para o esgotamento das reservas destes recursos ainda neste século, impulsionam cada vez mais a diversificação da matriz energética. A priorização ao uso de fontes de energia limpa, por exemplo, a partir de recursos renováveis, vem sendo pauta em pesquisas e bibliografias no Brasil e no mundo, e tem enfoque tanto na geração quando no armazenamento de energia. Dispositivos que convertem e armazenam energia, como capacitores e baterias, são fundamentais para a disponibilidade da eletricidade para pronto consumo. Capacidade de armazenamento, tempo de carregamento, segurança operacional, vida útil e custo, são alguns dos aspectos relacionados a tais equipamentos com alta relevância para as presentes e futuras aplicações da transformação tecnológica que já vivenciamos no âmbito da energia. A partir de avanços trazidos pelas novas tecnologias, estudos posteriores têm possibilitado a implementação de melhorias também em baterias já conhecidas. Caso como o das baterias Fe- Ni, que apesar de serem produzidas desde o fim do século XIX, caíram em desuso com o surgimento de materiais mais modernos, e nos últimos anos tiveram um renovado interesse como tópico em pesquisas para melhoria dos parâmetros técnicos e aumento de capacidade e eficiência energética. Este trabalho tem como intuito apresentar os recentes avanços aplicados nos métodos de fabricação, e na composição dos materiais e aditivos para os eletrodos e eletrólitos nas baterias Fe-Ni.

Anchoring ultrafine CoP and CoSb nanoparticles into rich N-doped carbon nanofibers for efficient potassium storage

Transition-metal compounds have received extensive attention from researchers due to their high reversible capacity and suitable voltage platform as potassium-ion battery anodes. However, these materials commonly feature a poor conductivity and a large volume expansion, thus leading to underdeveloped rate capability and cyclic stability. Herein, we successfully encapsulated ultrafine CoP and CoSb nanoparticles into rich N-doped carbon nanofibers (NCFs) via electrospinning, carbonization, and phosphorization (antimonization). The N-doped carbon fiber prevents the aggregation of nanoparticles, buffers the volume expansion of CoP and CoSb during charging and discharging, and improves the conductivity of the composite material. As a result, the CoP/NCF anode exhibits excellent potassium-ion storage performance, including an outstanding reversible capacity of 335 mA h g −1 , a decent capacity retention of 79.3% after 1000 cycles at 1 A g −1 and a superior rate capability of 148 mA h g −1 at 5 A g −1 , superior to most of the reported transition-metalbased potassium-ion battery anode materials.
