Abstract: Provided is a cap plate assembly provided to cover a cell case of a secondary battery, the cap plate assembly including a top plate having at least a portion penetrated to form a first accommodation hole for connecting an inside and outside of the cell case, and a first electrode unit coupled to the first accommodation hole from above and below the top plate, wherein the first electrode unit includes a first terminal plate held and mounted on the top plate, a first airtight member provided to separate the first terminal plate from the top plate, a first electrode terminal inserted and coupled into the first through hole so as to electrically connect from the inside of the cell case to the first terminal plate, and a first sub-plate connected to a bottom of the first electrode terminal.

Abstract: Provided are a resin composition for coating an engine piston and a method of fabricating the same. The resin composition contains carbon nanotubes (CNTs) as a reinforcement and is capable of providing a coated layer on at least a part of the engine piston, and the method includes adjusting a parameter expressed as a product of a weight ratio of CNTs in the resin composition and an average aspect ratio of CNTs, to control a coefficient of friction of the coated layer and viscosity of the resin composition.
