Extinguishing composition, method for preparing the same, secondary battery and battery pack

An electronic device includes an earphone jack assembly disposed to align with an opening in the housing of the electronic device. The earphone jack assembly includes at least one structure including a first passage having a first cross-sectional area, a second passage having a second cross-sectional area smaller than the first cross-sectional area, a third passage, and a microphone disposed outside of the at least one structure and including a substrate having a hole connected to the third passage. The first passage extends from the opening in a first direction, and includes a first end connected to the opening and a second end opposite to the first end, the second passage extends from the second end of the first passage in the first direction, and the third passage extends from the second passage in a second direction different from the first direction.

Electronic device including electronic part and earphone jack assembly

Disclosed is a graphite/DSA assembled electrode for a redox flow battery, obtained by assembling a graphite electrode made of micro-sized graphite and a DSA electrode using rolling thus improving cell performance including electrode durability, corrosion resistance, power density, energy efficiency and cycle properties. A method of manufacturing the graphite/DSA assembled electrode is also provided, which includes preparing a mixture composed of a graphite active material, a conductive material and a binder into a slurry using an alcohol, evaporating the alcohol from the slurry thus preparing a paste, thinly spreading the paste into an electrode sheet, and rolling the electrode sheet along with a DSA electrode thus obtaining the assembled electrode. A redox flow battery including the electrode thus obtained is also provided, which has increased electrode durability and corrosion resistance and enhanced power properties, energy efficiency and cycle performance.
