• electrolyte engineering, cell design, interlayers, or solid electrolyte interphases can be found elsewhere in excellent reviews [10][14][28]. Here, additionally, some patents are reviewed to examine the approaches that are followed to commercialize Na–S batteries. Finally, an outlook is provided on how far

Results show that these strategies have an undeniable positive influence on cycle stability and performance safety of sodium batteries [10]. Yet, there are currently also other strategies

A counterpart for the high-resolution physical properties (“how”) is needed to describe the local structure (“what”). For that purpose, one major drawback of AFM force

Besides typical 2D layered clays, fibrous (sepiolite, palygorskite) and tubular (halloysite, imogolite) clays are attracting growing interest in the development of a large variety of functional nanomaterials and nanocomposites for application in diverse

Examples are the direct assembly of carbon nanotubes and sepiolite under ultrasonic irradiation [19] and the generation of layered titanosilicates in the presence of sepiolite [20]. In this context, the use of organic–inorganic interphases has proved highly effective to

This factor can be a limitation when high crystallinity is required; in such cases, use of low reagent concentrations or surfactants is often required to keep the particles apart.
