Abstract. Besides a continuous increase of the worldwide use of electricity, the electric energy storage technology market is a growing sector. At the latest since the German energy transition ("Energiewende") was announced, technological solutions for the storage of renewable energy have been intensively studied. Storage technologies in various forms are commercially available. A widespread technology is the electrochemical cell. Here the cost per kWh, e. g. determined by energy density, production process and cycle life, is of main interest. Commonly, an electrochemical cell consists of an anode and a cathode that are separated by an ion permeable or ion conductive membranethe separator -as one of the main components. Many applications use polymeric separators whose pores are filled with liquid electrolyte, providing high power densities. However, problems arise from different failure mechanisms during cell operation, which can affect the integrity and functionality of these separators. In the case of excessive heating or mechanical damage, the polymeric separators become an incalculable security risk. Furthermore, the growth of metallic dendrites between the electrodes leads to unwanted short circuits. In order to minimize these risks, temperature stable and non-flammable ceramic particles can be added, forming so-called composite separators. Full ceramic separators, in turn, are currently commercially used only for high-temperature operation systems, due to their comparably low ion conductivity at room temperature. However, as security and lifetime demands increase, these materials turn into focus also for future room temperature applications. Hence, growing research effort is being spent on the improvement of the ion conductivity of these ceramic solid electrolyte materials, acting as separator and electrolyte at the same time. Starting with a short overview of available separator technologies and the separator market, this review focuses on ceramic-based separators. Two prominent examples, the lithium-ion and sodium-sulfur battery, are described to show the current stage of development. New routes are presented as promising technologies for safe and long-life electrochemical storage cells.

Sodium–sulfur (Na–S) battery technology has high potential for energy storage and load leveling in power systems, and it is one of the most developed types of high temperature battery. Owing to outstanding energy density, high efficiency of charge/discharge, low materials cost, and cycle life of up to 15 years, Na–S batteries are attractive for their use in relatively large‐scale energy storage system applications. However, there are several challenges to overcome for the safe operation of Na–S batteries, mostly related to the high operation temperatures. In this sense, the development of new solid electrolytes that possess high ionic conductivities at intermediate or room temperature is crucial. β‐Alumina and NASICON structure electrolytes are revised, and new alternatives, such as ceramic/polymer composites, are also gathered. There also exists novel focus on Na–S technology in order to increase the obtained capacity and cyclability consisting of using nanostructured carbon to host sulfur or to bind it to a polymer. In addition, hybrid technologies combining Na–S with ZEBRA or oxygen rocking‐chair batteries are currently arising as alternative storage devices. As Na–S technology was introduced in the mid‐1970s, a number of different patents have been developed. Trends observed in the new patents are twofold: on the one hand, they aim to integrate these batteries into the electrical grid in order to compensate the fluctuations of renewable energies; on the other hand, they show battery component improvements in order to obtain lower operating temperatures.

Sodium–sulfur (Na‐S) battery technology is one of the most developed types of high‐temperature battery, due to its considerable potential for energy storage and load leveling in power systems. These systems are eligible for use in large‐scale energy storage system applications due to their outstanding energy density, high efficiency of charge/discharge, low materials cost, and long life cycle of up to 15 years. However, several challenges must be overcome to ensure the safe operation of Na‐S batteries – mostly related to the reduction of the high operation temperatures. For this purpose, it is critical to develop new solid electrolytes with high ionic conductivity at room temperature. Taking this into account, ceramic/polymer composites are good candidates to achieve this goal. However, it is important to note an increase of capacity and cyclability is also desirable for Na‐S technology, and one of the strategies used to address this issue is the use of nanostructured carbon to host sulfur or to bind it to a polymer. Since the inception of Na‐S technology in the mid‐1970s, several patents have been developed. Analysis of these patents indicate that, on the one hand they aim to integrate these systems into the electrical grid to compensate the fluctuations of power demand and supply, especially of renewable energies, while on the other hand they show battery component improvements to achieve lower operating temperatures.
