An embodiment of the present invention relates to an adhesive, a bonded body or a method for producing a press-bonded body. The adhesive includes a fluoroelastomer and is for bonding base materials in the presence of carbon dioxide in a liquid state, a gas-liquid mixture state, or a nearly liquid state. The bonded body is such that two or more base materials are bonded to each other with the adhesive. The method for producing a press-bonded body includes a step 1 in which two or more base materials are press-bonded in the presence of the adhesive including a fluoroelastomer and carbon dioxide in a liquid state, a gas-liquid mixture state, or a nearly liquid state.

Copolymers of one or more halogenated olefins and one or more halogenated co-monomers selected from the group consisting of halogenated alkenyl ethers, halogenated alkenyl esters, and halogenated (meth)acrylates are useful in various end-use applications wherein the presence of halogen (e.g., fluorine) in the copolymer imparts one or more desirable properties, as compared to analogous copolymers not containing halogen.

An ion-conducting material, a core-shell structure containing the ion-conducting material, an electrode prepared with the core-shell structure and a metal-ion battery employing the electrode are provided. The core-shell structure includes a core particle and an organic-inorganic composite layer formed on the surface of the core particle for encapsulating the core particle.
