The growing demand of electric vehicles and rapid consumption rechargeable lithium-ion batteries (LIBs) require recycling spent cathode active materials (CAMs) to reduce hazardous wastes supply raw LIB production. To separate CAMs from the cathode, direct calcination polyvinylidene fluoride (PVDF) binder is widely applied, which leads high energy release toxic hydrogen fluoride. It desirable ha...

Powering crucial for miniaturized electronic devices requiring fast charging, high energy density and long term-durability. 3D micro-supercapacitors are an attractive storage solution at millimeter scale to power IoT exhibiting small form factor packaging issues. However, there nowadays not any microdevices...

The alkali nitrate mixtures are promising phase change materials (PCMs) in the temperature range (373?573) K for development of thermal storage systems. In this context, their thermochemical properties and diagrams which provide useful information needed better use. present paper, based on cesium nitrate, lithium sodium studied by both experimental optimization techniques. Thus, a critical anal...

Highly conductive electrolyte materials are an essential part of many electrochemical systems, such as fuel cells, solar cells, batteries, electrochromic devices, and next-generation renewable-energy sources. The growing diversity in batteries and electrochemical cells increases the demand for novel electrolyte materials. For instance, in solar-cell applications, an electrolyte material with hi...

Submicromolar to picomolar lower detection limits have recently been obtained with various polymer membrane ion-selective electrodes by minimizing biases due to ion fluxes through the membrane. For the best performance, the compositions of the membrane and inner solution should be optimized for each application. Given the number of parameters to be adjusted, it has been difficult to find the be...

Octahedral-shaped perovskite PbTiO3 nanocrystals (PT OCT) with well-defined {111} facets exposed have been successfully synthesized via a facile hydrothermal method by using LiNO3 as an ion surfactant. The Li-O bond on the surface of PT OCT nanocrystals is essential to the stability of such nanocrystals and also results in a dramatic high visible-light photocatalytic activity.

Lithium-sulfur batteries (LSBs) are among the most promising next generation battery technologies. First prototype cells show higher specific energies than conventional Li-ion (LIBs) and active material is cost-effective ubiquitously abundant. However, Li-S still suffer from several limitations, mainly cycle life, inflation of cells, also lack a component production value chain. As this system ...

The key to realize long-life high energy density lithium batteries is exploit functional electrolytes capable of stabilizing both voltage cathode and anode. emergence localized high-concentration (LHCEs) shows great promise for ameliorating the above-mentioned interfacial issues. In this work, a difluoro(oxalate)borate (LiDFOB) based nonflammable dual-anion LHCE designed prepared. Dissolving in...
