In the past few years, supercapacitors (SCs) have attracted great attention in both academic and industrial sectors due to their high energy storage efficiency, reliable stability, eco-friendly process. Flexible solid-state SCs as one of ongoing focuses for development wearable portable electronics become most promising devices smart power system density, fast electrochemical response, efficien...

In the past few decades, multifunctional optical crystals for all-solid-state Raman lasers have been widely studied by many scholars due to their compactness, convenience and excellent performance. this review, we briefly show two kinds of crystals: self-Raman (laser effects) self-frequency-doubled (frequency-doubling crystals. We firstly introduce properties laser crystals, including vanadate,...

All-solid-state sodium batteries (ASSBs) are regarded as the next generation of sustainable energy storage systems due to advantages abundant resources, and their exceptional high density. Nevertheless, there still grand challenges realize practical applications, such limited types solid-state electrolytes (SEs), low ionic conductivity SEs, charge-transfer impedance, interfacial issues, Na dend...
