Recently, transition metal oxides, such as ruthenium oxide (RuO₂), manganese dioxide (MnO₂), nickel oxides (NiO) and cobalt oxide (Co₃O₄), have been widely investigated as electrode materials for pseudo-capacitors. In particular, these metal oxides with mesoporous structures have become very hot nanomaterials in the field of supercapacitors owing to their large specific surface areas and suitab...

1 Energy storage is an essential element of the complete landscape of energy processes, closely coupled with energy generation, transmission and usage. Development of lithium-based rechargeable batteries with higher energy density, lower costs and improved safety is highly desirable1–3. Over the past 25 years, lithiumion batteries based on conventional intercalation electrode materials have pla...

We demonstrate a novel and versatile pipet-based approach to study the landing of individual nanoparticles (NPs) on various electrode materials without any need for encapsulation or fabrication of complex substrate electrode structures, providing great flexibility with respect to electrode materials. Because of the small electrode area defined by the pipet dimensions, the background current is ...

Recently, MXenes, which are two-dimensional early transition metal carbides and carbonitrides, have attracted wide attention because of their unique properties. In this study, the electrode applications of Ti2CTx, a member of the MXene family, in pentacene organic field-effect transistors (OFETs) are assessed. Kelvin probe force microscopy analysis was performed to determine the work function o...

In this paper, we present a systematic study of the effects of p- and n-doping in small molecules on the voltage and capacity of organic electrode materials for electrochemical batteries. In particular, coronene, phenalene derivatives as well as disodium terephthalate and related fused ring derivatives, representing often used building blocks in organic electrode materials, are chosen as model ...

Biomass materials are promising precursors for the production of carbonaceous materials due to their abundance, low cost and renewability. Here, a freestanding wrinkled carbon membrane (WCM) electrode material for flexible supercapacitors (SCs) was obtained from flower petal. The carbon membrane was fabricated by a simple thermal pyrolysis process and further activated by heating the sample in ...

Carbon materials such as activated carbon and carbon black are popular for use in electrodes for energy conversion and storage due to their conductivity and relative inertness. However, these materials are not thermodynamically stable and show various forms of degradation after long-term use [1]. Because electrode systems are inhomogeneous at a variety of length scales, improving performance an...

Rechargeable batteries, such as lithium-ion batteries, play an important role in the emerging sustainable energy landscape. Mechanical degradation and resulting capacity fade in high-capacity electrode materials critically hinder their use in high-performance lithium-ion batteries. This paper presents an overview of recent advances in understanding the electrochemically-induced mechanical behav...

Nanofluidic devices make use of molecular-level forces and phenomena to increase their density, speed and accuracy. However, fabrication is challenging, because dissimilar materials need to be integrated in three dimensions with nanoscale precision. Here, we report a three-dimensional nanoscale liquid glass electrode made from monolithic substrates without conductive materials by femtosecond-la...
