To improve the practical performance of Na-ion batteries, electrode structure engineering provides a new route to improve the electrochemical efficiency of the cathode active material. In this study, we suggest a new route of one-pot spray engineering to design Na0.44MnO2 cathodes to realize high-rate and cycle-stable Na-ion battery performance. Th...
To advance the understanding of the degradation of the liquid electrolyte and Si electrode, and their interface, we exploit the latest developments in cryo-atom probe tomography. We evidence Si anode corrosion from the decomposition of the Li salt before charge-discharge cycles even begin. Volume shrinkage during delithiation leads to the developme...
To meet the urgent requirement of sustainable energy storage technologies, it is essential to incorporate efficient waste management into designing energy storage materials. Herein, we report an environmentally responsible pathway to utilize the recycled V2O5 from V-Cr slag leaching solution. Because of the fact that trace Cr are existed in the rec...

The commercial application of silicon oxide (SiOx)-based anode materials in lithium-ion batteries (LIBs) is hindered by their poor electrochemical performance and difficulty in large-scale production. Here, we report a scalable synthesis of a carbon-coated SiO(x )composite (SiOx/C) as an excellent and stable anode material for LIBs. By employing th...

Upcycling of photovoltaic silicon (Si) waste to produce high-energy-density energy storage materials represents an effective way to achieve carbon neutrality. However, at present, photovoltaic Si waste (WSi) can only be suitable for degraded utilization because WSi recycling processes are limited by deep oxidation, entrainment of trace impurities, ...

Ammonia is useful for the production of fertilizers and chemicals for modern technology, but its high toxicity and corrosiveness are harmful to the environment and human health. Here, we report the recyclable and tunable ammonia adsorption using a robust imidazolium-based MOF (JCM-1) that uptakes 5.7 mmol g(-1) of NH3 at 298 K reversibly without st...
