Coupling cathodic electrochemical CO2 reduction (eCO2RR) with anodic electrochemical 5-hydroxymethylfurfural oxidation reaction (HMFOR) is an appealing approach to co-produce value-added chemicals and simultaneously lower the energy input, while the main challenge is to develop effective electrocatalysts for eCO2RR and HMFOR. Inspired by the techno-economic analysis, we herein report a coupling system

It is widely believed that replacing flammable liquid electrolyte (LE) with solid electrolyte can solve the safety problem of lithium batteries. However, the safety of solid-state batteries (SSBs) has rarely been discussed, so its reliability is still being questioned. This work has prepared promising quasi-solid electrolytes (QSEs) for all-round safety evaluation. On this basis, it is proved that

The enhanced areal energy of three-dimensional (3D) micro-supercapacitors has made these miniaturized energy-storage components increasingly important at the dawn of the Internet of Things. Although ultrahigh-capacitances have been obtained with Ru-based pseudocapacitive materials, their substitution with abundant non-noble transition metals is a key requirement to reduce the price of electrochemical

Aqueous Zn-ion batteries (AZIBs) have been considered as one of the most auspicious large-scale energy storage systems, However, the hydrogen evolution, side reaction and dendrite growth of Zn anode severely hinder its practical application and scalability. Herein, an effective and economical strategy to resolve these problems by introducing a bifunctional additive uridine into electrolyte is reported

Intermittent renewables require hefty backup power sources that compensate for sudden generation shortfalls and ensure grid stability and balance, both across time and geographies. As a result, carbon emissions associated with electricity have increased in the last few years, making a 100% clean system nothing more than an aspiration. Here, we have used a simulation-based algorithm to show the indispensability

In recent times, there has been a growing interest among researchers in aqueous energy storage devices that utilize non-metallic ammonium ions (NH4+) as charge carriers. However, the selection of suitable materials for ammonium storage presents significant challenges. The understanding of the energy storage mechanism in electrodes for ammonium ion-based devices remains limited, which hampers the development

All-polymer solar cells (all-PSCs) have recently made remarkable progress owing to the emergence of polymerized small molecule acceptors. However, the fabrication of all-PSCs featuring high efficiency, desirable photostability and excellent mechanical durability remains challenging. Herein, we designed and synthesized a series of novel non-volatile solid additives, namely DTC-Cn (n represents 8, 12

The dendrite growth on the surface of zinc anodes and formation of inactive by-products of Zn4(OH)6SO4.xH2O (ZHS), mainly attributed to the “tip effect” of an uneven surface and water corrosion of zinc anode, have seriously shrunk the anode life and hindered the commercialization of aqueous zinc ion batteries (AZIBs). Herein, we describe a bifunctional interface constructed by zwitterionic surfactant

Andrea Clabough explores transatlantic leadership on energy security and where cooperation may enhance the energy transition for the USA and Europe.

Electrolyte plays a crucial role in the construction of electrode interfaces of high energy lithium metal battery systems. For advanced Li-SPAN battery system, the forbidden of shuttle effect in traditional carbonate electrolyte is attributed to the formation of the cathode/electrolyte interface (CEI). Unfortunately, the inherent electrochemical instability of Li metal in carbonate electrolyte limits

Silicon (Si) anode with high theoretical specific capacity (3579 mAh g−1) offers great promise for realizing high-energy solid-state batteries (SSBs). However, given Si’s huge volume variations during cycling, sluggish kinetics and unfavorable interface stability with solid-state electrolyte (SSE), its practical potential in SSBs has not been fully exploited. Herein, we propose a design of highly-dense

With the rapid prosperity of the global electric vehicle market and increasing demand for the higher user experience of portable electronics, the development of high-performance lithium-ion batteries (LIBs) with fast-charging capability has become an inevitable trend. However, the utilization of mainstream graphite anodes in LIBs presents critical technological obstacles such as capacity degradation
