Abstract: A gas-exhausting apparatus includes a gas-exhausting body and a gas-exhausting mechanism. The gas-exhausting mechanism includes a connecting assembly and a gas-ventilating member. The connecting assembly includes first and second connecting members. The first connecting member is provided with a first through hole for communicating with an inside of the battery cell. The second connecting member is provided with a second through hole for communicating with an outside of the battery cell. The first connecting member is configured to attach to a surface of the gas-ventilating member facing the inside of the battery cell. The second connecting member is configured to attach to a surface of the gas-ventilating member facing away from the inside of the battery cell. An orthographic projection of the first through hole on the gas-ventilating member and an orthographic projection of the second through hole on the gas-ventilating member are arranged to be staggered from each other.

Abstract: In a method of producing an anti-reflective surface, instead of etching subwavelength structures directly onto the substrate, a thin film layer of topcoat is deposited onto the surface of the substrate, and the anti-reflective surface is created by etching the structures into the topcoat. Because the thin film can be applied to substrates made of a large number of different materials, only common etching recipes need to be developed for a few thin film materials. The present method overcomes the shortcoming that existing methods of etching structures directly on a substrate would require a different etching recipe for each substrate made of a different material.
