wherein R.sup.1 is a C.sub.10-20 alkyl group, or a C.sub.1-5 alkyl group containing an amide group; R.sup.2 and R.sup.3 are each independently a C.sub.1-9 alkyl group; and X.sup. is a C.sub.1-5 anionic organic group containing a carboxylate ion or a sulfonate ion. A method for producing a wafer, wherein in the step of polishing a wafer, polishing is performed until a height difference between a central region and a peripheral region of the wafer becomes 100 nm or less.

The present invention relates to an adhesive composition, an adhesive film, a method of manufacturing the adhesive film and an organic electronic device (OED) that are used to encapsulate an organic electronic element. The adhesive composition can form an encapsulant layer having an excellent adhesive property, impact resistance, heat-protecting property and moisture blocking property, so that an OED that includes an element encapsulated with the adhesive composition can exhibit an excellent lifespan property and durability.

Provided is particulate of a cathode active material for a lithium battery, comprising one or a plurality of cathode active material particles being embraced or encapsulated by a thin layer of a high-elasticity polymer having a recoverable tensile strain no less than 5%, a lithium ion conductivity no less than 10.sup.6 S/cm at room temperature, and a thickness from 0.5 nm to 10 m, wherein the polymer contains an ultrahigh molecular weight (UHMW) polymer having a molecular weight from 0.510.sup.6 to 910.sup.6 grams/mole. The UHMW polymer is preferably selected from polyacrylonitrile, polyethylene oxide, polypropylene oxide, polyethylene glycol, polyvinyl alcohol, polyacrylamide, poly(methyl methacrylate), poly(methyl ether acrylate), a copolymer thereof, a sulfonated derivative thereof, a chemical derivative thereof, or a combination thereof.

A dispensable chemical composition comprising a blend of siloxane polymeric components, with a low viscosity component in an amount greater than a high viscosity component, and suitable to integrate a high amount of filler materials while maintaining rheological features of thixotropic index and viscosity values at low and high shear rates proper for a dispensing paste.

Setter plates are fabricated from Li-stuffed garnet materials having the same, or substantially similar, compositions as a garnet Li-stuffed solid electrolyte. The Li-stuffed garnet setter plates, set forth herein, reduce the evaporation of Li during a sintering treatment step and/or reduce the loss of Li caused by diffusion out of the sintering electrolyte. Li-stuffed garnet setter plates, set forth herein, maintain compositional control over the solid electrolyte during sintering when, upon heating, lithium is prone to diffuse out of the solid electrolyte.
