摘要： Disclosed are a method of manufacturing a non-slip plate and a non-slip plate manufactured thereby. The method includes preparing a base metal plate for joint design, washing and surface treatment, preparing a non-slip material, adhering the non-slip material to the bonding surface of the base metal plate to form a protrusion, and brazing the base metal plate having the non-slip material adhered thereto in a brazing furnace. The non-slip plate is applied to vehicles to impart non-slip performance thereto, and can be semi-permanently used.

摘要： A complex membrane for an electrochemical device such as a lithium secondary battery, its manufacturing method, and an electrochemical device having the complex membrane are disclosed. The complex membrane includes a micro-porous polyolefin membrane, and a web-phase porous membrane united to at least one side of the micro-porous polyolefin membrane and composed of nano-fibers. Since the complex membrane is capable of absorbing an electrolyte uniformly, it greatly improves performance of a battery when being used for an electrochemical device. In addition, owing to excellent mechanical strength and good binding capacity to an electrode, it helps to increase a process rate for manufacturing the battery.
