An environmentally sustainable, biodegradable, zwitterion-functionalized sepiolite clay composite membrane suitable for electrochemical energy storage and conversion devices is disclosed. The membrane is synthesized by dispersing naturally abundant sepiolite clay in water, functionalizing the slurry with zwitterions such as betaine, alanine, arginine, proline, or valine, and vacuum drying at ambient temperature to yield a free-standing, flexible composite membrane. The zwitterionic compounds chemically attach to surface silanol sites of sepiolite fibers, partially disaggregating fiber bundles and creating controlled hierarchical porosity. Substantially free of polymeric binders, metals, and carbonaceous materials, these membranes exhibit improved ionic conductivity, thermal stability, and chemical resistance compared to traditional separators. They provide ionic conduction and electrical insulation as separators in lithium-ion batteries, sodium-ion batteries, supercapacitors, and fuel cells, thus addressing critical performance, sustainability, and safety requirements in energy storage technologies.

Abstract The invention relates to the coating of anion exchange membranes (AEM) with catalytically active substances. The CCM thus obtained are used in electrochemical cells, especially for alkaline water electrolysis. It was an object of the invention to specify a process for producing a CCM by direct 5 coating which maintains the necessary planarity of the AEM and ideally avoids the use of lost films and eschews CMR substances. Swelling shall also be minimized. The process shall also be performable with fluorine-free ionomers. The invention is based on the finding that the addition of certain organic substances has the result that the AEM swells only to a small extent, if at all (antiswelling agent). It has surprisingly been found that substances suitable as antiswelling agents 10 are identifiable by their solubility behaviour, more particularly by their Hansen parameters.

The invention relates to the coating of anion exchange membranes with catalytically active substances. The catalytically actively coated anion exchange membranes are used in electrochemical cells, especially for water electrolysis. The problem addressed by the invention is that of specifying a process for coating an anion exchange membrane which can be conducted at relatively low temperatures. This problem is solved by a swelling step. Aside from the swelling step and the processing temperature, the sequence of the process according to the invention resembles a decal process. However, the use of the partly liquid swelling agent means that the process according to the invention can be considered to be a wet process. The process enables the processing of anion-conducting polymers at moderate temperatures. The anion-conducting polymers may be present in the anion exchange membrane and/or in the composition that is applied to the anion exchange membrane. The advantage of the process according to the invention is that it can be conducted at comparatively low temperatures, namely below 100°C.

Abstract The invention relates to the coating of anion exchange membranes (AEM) with catalytically active substances. The CCM thus obtained are used in electrochemical cells, especially for alkaline water electrolysis. It was an object of the invention to specify a process for producing a CCM by direct 5 coating which maintains the necessary planarity of the AEM and ideally avoids the use of lost films and eschews CMR substances. Swelling shall also be minimized. The process shall also be performable with fluorine-free ionomers. The invention is based on the finding that the addition of certain organic substances has the result that the AEM swells only to a small extent, if at all (antiswelling agent). It has surprisingly been found that substances suitable as antiswelling agents 10 are identifiable by their solubility behaviour, more particularly by their Hansen parameters.
