Batteries and Supercapacitors

batteriesLithium-ion or otherwise, batteries keep lots of things going, and enable a mobile lifestyle: from mobile phones to intercontinental air travel. Batteries are complex devices whose overall performance and usefulness depend on many factors such as energy density, efficiency, durability, and sustainability. Research in this area is by nature interdisciplinary and involves chemists, physicists, materials scientists, and engineers.

NASICON-Structured Materials for Energy Storage

NASICON‐Structured Materials for Energy Storage

NASICON-structured materials exhibit great structural stability and fast ionic conductivity. More importantly, these materials can be used as cathodes, anodes, and solid electrolytes. In general, the interfacial resistance between a solid electrolyte and the electrodes in solid-state batteries is large. However, if all-NASICON solid-state batteries can be fabricated, the interfacial resistance may be decreased because it can form a solid-solution or composite between electrodes and electrolytes due to their similar structure.
