Abstract: Proposed is a method of synthesizing a solid-state electrolyte of Li3HalO formula for use in a lithium-ion battery. The method consists of uniformly mixing at least LiOH and LiHal in a stoichiometric quantities, heating the prepared mixture to a melting temperature and causing a reaction of formula (2LiOH+LiHal=Li3HalO+H2O) between the at least LiOH and LiHal in a process free of forming a perovskite structure and at a temperature, at which H2O that forms at the aforementioned reaction is converted into a bound form, whereby a reaction product is obtained. According to another modification of the method, prior to the stage of melting the mixture, a reinforcement mesh is immersed into the mixture, whereby after mixture is solidified, a solid-state electrolyte reinforced with the mixture embedded into its material is obtained.

Abstract: Disclosed is a carbon-based fiber sheet and a lithium-sulfur battery including the same. The carbon-based fiber sheet for the lithium-sulfur battery is doped with a high concentration of nitrogen and thus plays a role of preventing diffusion by adsorbing lithium polysulfide eluted from a positive electrode during charging and discharging, thereby suppressing a shuttle reaction and thus improving capacity and lifecycle properties of the lithium-sulfur battery.

Abstract: A degassing unit to be connected fluid-tightly to a pressure compensation opening of an electronics housing has a base body with gas passage opening. A semipermeable membrane, fastened fluid-tightly to a membrane carrier, allows gaseous media to pass from an environment into the electronics housing and in reverse but prevents passage of liquid media and solids. In normal operation, the membrane covers the gas passage opening. An axial seal circumferentially extends about the gas passage opening. The membrane carrier is moveable relative to the base body and, in normal operation, is pressed by axial force seal-tightly against the axial seal. The membrane carrier, when a predetermined pressure difference between housing interior and environment is surpassed, lifts off the base body to release an emergency degassing opening surrounding the membrane. The axial seal is a lip seal and made of a material softer than a material of the membrane carrier.
