摘要:
Provided is a microporous organic/ inorganic composite coated layer comprising a heat resistant resin and inorganic particles, formed on at least one side of microporous polyethylene. The microporous polyethylene composite film is characterized by sufficient permeability and heat resistance at the same time, of which the permeability (Gurley) of overall composite film including a coated layer is not more than 300 sec; shrinkage after 150° C. for 1 hour is 0-3% in both MD/TD directions; maximum shrinkage in TMA is not more than 3%, and TMA meldown temperature is 145-200° C. The microporous polyethylene composite film formed by means of the coated layer possesses stability at high temperature as well as excellent permeability, thereby ensuring reliability and efficiency of a battery at the same time. A separator which conforms to high power/high capacity can be provided thereby.

摘要:
Provided is a method of manufacturing a microporous polyolefin composite film with a thermally stable porous layer at high temperature, particularly, to a method of manufacturing a microporous polyolefin composite film with a thermally stable porous layer at high temperature, comprising preparing a polyolefin microporous film using a composition containing a polyolefin resin; coating a solution, in which a high heat-resistant resin is dissolved in a solvent, on one surface or both surfaces of the polyolefin microporous film; phase-separating the polyolefin microporous film coated with the solution by contacting with a nonsolvent after the coating; and drying the polyolefin microporous film so as to remove the solvent and nonsolvent remained after the phase-separating, and thus forming the thermally stable layer at high temperature.
摘要:
A plug or connector including a coded magnet and an electrical contact. As the plug approaches a corresponding port, the coded magnet interacts with a magnet within the port. The interaction between the plug coded magnet and the port coded magnet provides a force to connect and/or align the plug with the port. Once the plug is received within the port, if a process is completed, the coded magnets polarities are altered to eject the plug from the port.
