Thermal runaway of lithium-ion batteries may be prevented by using

An in-depth understanding of material behaviours under complex electrochemical environment is critical for the development of advanced materials for the next-generation rechargeable ion batteries. The dynamic conditions inside a working battery had not been intensively explored until the advent of various in situ characterization techniques. Real-time transmission electron microscopy of electro...

Lithium solid electrolytes can potentially address two key limitations of the organic electrolytes used in today's lithium-ion batteries, namely, their flammability and limited electrochemical stability. However, achieving a Li(+) conductivity in the solid state comparable to existing liquid electrolytes (>1 mS cm(-1)) is particularly challenging. In this work, we reveal a fundamental relations...

Paper-based materials are emerging as a new category of advanced electrodes for flexible energy storage devices, including supercapacitors, Li-ion batteries, Li-S batteries, Li-oxygen batteries. This review summarizes recent advances in the synthesis of paper-based electrodes, including paper-supported electrodes and paper-like electrodes. Their structural features, electrochemical performances...

Lithium ion (Li-ion) batteries have been widely used in various kinds of applications, including consumer electronics, green energy systems and electrical vehicles. Since the charging method has a significant influence on the performance and lifetime of Li-ion batteries, an intelligent charging algorithm which can properly determine the charging current is essential. In this study, a fuzzy-logi...

Scanning ion conductance microscopy imaging of battery electrodes, using the geometry shown in the figure, is a tool for in situ nanoscale mapping of surface topography and local ion current. Images of silicon and tin electrodes show that the combination of topography and ion current provides insight into the local electrochemical phenomena that govern the operation of lithium ion batteries.

The Front Cover shows magnesium-doped MnO2 nanorods that are used as an electrode material capable of intercalating/de-intercalating aluminum ions. open tunnel structure the nanomaterial well presence dopant magnesium cations facilitates this process, opening up possibility using in aqueous Al-ion batteries or supercapatteries.
