Proposed is a method of synthesizing a solid-state electrolyte of Li.sub.3HaIO formula for use in a lithium-ion battery. The method consists of uniformly mixing at least LiOH and LiHaI in a stoichiometric quantities, heating the prepared mixture to a melting temperature and causing a reaction of formula (2LiOH+LiHaI=Li.sub.3HaIO+H.sub.2O) between the at least LiOH and LiHaI in a process free of forming a perovskite structure and at a temperature, at which H.sub.2O 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.

The present invention provides a transparent electroconductive layer-equipped cover element having a pressure-sensitive adhesive sheet preliminarily laminated thereto, wherein the pressure-sensitive adhesive sheet comprises a pressure-sensitive adhesive layer in which a refractive index adjustment zone having a refractive index greater than that of a base pressure-sensitive adhesive material thereof is formed over a given range from a surface of the pressure-sensitive adhesive layer in a thickness direction thereof, whereby: in a lamination process of a customer which is a supply destination of the transparent electroconductive layer-equipped cover element, it becomes possible to eliminate a need to distinguish between obverse and reverse sides of the pressure-sensitive adhesive sheet itself; and, when the transparent electroconductive layer-equipped cover element is bonded to an optical element through the pressure-sensitive adhesive layer, it becomes possible to suppress internal reflection in a laminate formed of these optical elements.

A method of making a proppant-gel matrix comprising: a) hydrating a gelling agent to form a hydrated gelling agent; b) adding a basic compound to the hydrated gelling agent to form a basic hydrated gelling agent having a pH in the range of 11.5 to 14.0; c) mixing the basic hydrated gelling agent and a proppant to form a basic hydrated gelling system; and d) adding a crosslinking agent to the basic hydrated gelling system to form the proppant-gel matrix, is disclosed. The proppant-gel matrix can then be used as a fracturing fluid in a hydraulic fracturing process.

A system for the integral chlorine dioxide production with relatively independent sodium chlorate electrolytic production and chlorine dioxide production is provided. The system may feed electrolyte solution into a solid-liquid filter, filtering out the crystal and eliminating sodium chloride and sodium dichromate. The sodium chlorate crystal may be fed into a chlorine dioxide generator after dissolving, while sodium chloride and sodium dichromate solution separately return to electrolyzer for electrolysis process. Sodium chloride may be constantly formed as a by-product in the chlorine dioxide production unit, and solution containing the sodium chloride is withdrawn from the generator and, after filtration, washing and dissolution, recycled back to sodium chlorate production unit. This way, there is no need of sodium chloride make-up.
