In order to solve various problems such as a reduction in a paint resin with the progress of electrodeposition coating treatment and remelting of a coating film or the occurrence of pinholes caused by an increased concentration of an electrolyte as a result of the reduction, upsizing of a hollow electrode with a membrane for electrodeposition coating combined with a barrier membrane (e.g., an ion exchange membrane) and an increase in the number of components should be avoided. In order to realize this, a barrier membranesuch as an ion exchange membrane is attached to the exterior surface of an electrode main body, which is in a hollow state made of a conductive material and configured so as to allow a liquid to pass through freely between the inside and outside of the electrode serving as a support.

Hollow electrode with film for electrodeposition coating

A polymer electrolyte composition characterized by comprising: (1) a crosslinked material of a polyether binary copolymer which has a main chain comprising repeating units represented by the formula (i) and crosslinking units represented by the formula (ii) and which has a weight-average molecular weight of 10to 10, (2) an electrolyte solution comprising an aprotic organic solvent, (3) an additive, as an optical ingredient, which comprises an ether compound having an ethylene oxide unit, and (4) an electrolyte salt compound comprising a lithium salt compound. The composition is excellent in liquid retention and ionic conductivity, is usable in a wide temperature range, and has excellent electrochemical properties.

Crosslinked polymer electrolyte and use thereof

A polyether copolymer having a weight-average molecular weight of 10to 10, formed from 3 to 30% by mol of a repeating unit derived from propylene oxide, 96 to 69% by mol of a repeating unit derived from ethylene oxide, and 0.01 to 15% by mol of a crosslinkable repeating unit derived from a reactive oxirane compound, gives a provide a crosslinked solid polymer electrolyte which is superior in processability, moldability, mechanical strength, flexibility and heat resistance, and has markedly improved ionic conductivity.

Solid polymer electrolyte and use thereof

An electrolyte composition, which contains (1) a polymer having an ether linkage optionally having a crosslinkable functional group, (2) an additive containing an organic silicon compound having an ethylene oxide unit, and (3) an electrolyte salt compound, is excellent in mechanical properties and ionic conductivity.

Polyethylene oxide-based electrolyte containing silicon compound

A solid polymer electrolyte containing (I) a crosslinked material obtainable by crosslinking a composition containing (i) a polyether copolymer having a weight-average molecular weight within a range from 10 to 10 and having 5 to 95 mol % of repeating unit derived from a glycidyl compound, and 95 to 5 mol % of repeating unit derived from ethylene oxide, (ii) a crosslinking agent selected from organic peroxides and azo compounds, and (iii) a crosslinking aid which is an organic compound having a carbon-carbon double bond and an imide group, (II) an electrolyte salt compound, and (III) a plasticizer, is excellent in mechanical properties and ionic conductivity.
