The growing interest in wearable electronics has triggered an enormous demand for flexible/wearable power sources. Flexible batteries, including lithium-ion batteries, Sodium-ion batteries, and Zinc/Zinc-Air batteries have been developed greatly. Nanofiber nonwoven fabrics form highly porous networks with remarkable interconnectivity between their pores, making them play an important role in flexible batteries as separators, current collectors and electrodes, etc. It looks that nanofiber nonwoven fabrics are promising to apply in flexible batteries, thus it is time to summarize their fabrication technology, flexible characteristics, electrochemical performance, and application prospects. This review paper focused on the current application status, emerging developments, and challenges of nanofiber nonwoven fabrics produced by electrospinning on flexible batteries. It is hopeful that this job will provide important references for the flexible batteries industrialization.

“…Wei et al reported the higher specific surface area and low density (4.93 g/cc) of TiC compared to other TMC. 19 With regard to the TiC unique positive features, they can be used as electrocatalyst in fuel cells or electrolyzers. 20 The Li-O 2 battery has received attention as a candidate for the next-generation batteries due to its extremely high-energy density (11.680 Wh/kg) based on the reaction of Li 2 O 2 formation and decomposition.…”

Titanium carbide-based thin films have been produced by DC magnetron sputtering. It was demonstrated that the same technology with changing of the deposition parameters, such as deposition temperature or power of Ti target, resulted in the preparation of TiC/a:C thin films with various structures. The structure of thin films and volume fraction of amorphous and crystal phases were precisely tailored by the control of deposition parameters. These ceramic nanocomposite TiC/a:C thin films according to their various structures, hence, their different mechanical, tribological, or wetting parameters can be used in wide range of applications.

Skalierbare Synthese von Multi‐Metall‐Elektrokatalysatorpulvern und ‐elektroden und ihre Anwendung für die Sauerstoffentwicklung und Wasserspaltung

Multimetall-Elektrokatalysatoren bieten nahezu unbegrenzte katalytische Möglichkeiten, die sich aus synergistischen Elementwechselwirkungen ergeben. Wir schlagen eine Polymer/Metallsalz-Sprühtechnik vor, die leicht angepasst werden kann, um eine große Vielfalt von Multimetall-Katalysatormaterialien mit unterschiedlicher Zusammensetzung herzustellen. Um dies zu demonstrieren, wurden 11 Katalysatoren synthetisiert, charakterisiert und für die Sauerstoffentwicklungsreaktion (OER) untersucht. Weitere Untersuchungen des aktivsten OER-Katalysators, nämlich CoNiFeMoCr, ergaben eine polykristalline Struktur, und Operando-Raman-Messungen deuten darauf hin, dass mehrere aktive Zentren an der Reaktion beteiligt sind. Darüber hinaus wurden auf Ni-Schaum basierende CoNiFeMoCr-Elektroden entwickelt und für die Wasserspaltung in Durchflusselektrolysezellen mit Elektrolytspalten und in "zero-gap" Membran-Elektroden-Anordnungen (MEA) eingesetzt. Die alkalischen MEA-Elektrolyseure erreichten bis zu 3 A cm À 2 , und 24-Stunden-Messungen zeigten keinen Verlust der Stromdichte von 1 A cm À 2 .
