Claims
- 1. A manufacturing method for producing a separator for a lithium secondary battery including:
- contacting a separator matrix having a microporous membrane comprising a polyolefin selected from the group consisting of polyethylene, polypropylene, and combinations thereof with a surface active agent for a time sufficient to perform a lyophilic treatment,
- impregnating a mixed solution into said separator matrix, wherein said mixed solution is produced by adding a mixture comprising an oligomer and a monomer with said mixed solution being capable of being polymerized into an organic electrolyte by ultra violet irradiation, and
- developing said separator matrix on a glass board having a surface coated by at least one fluoroplastic material by irradiating ultraviolet ray through said glass board to polymerize said mixed solution to produce a separator matrix comprising an ionic conductive gel electrolyte.
- 2. A manufacturing method for producing a separator for a lithium secondary battery including:
- oxidizing a separator matrix having a microporous membrane comprising a polyolefin selected from the group consisting of polyethylene, polypropylene, and combinations thereof by plasma irradiation for a time sufficient to perform a lyophilic treatment,
- impregnating a mixed solution into said separator matrix, wherein said mixed solution is produced by adding a mixture comprising an oligomer and a monomer with said mixed solution being capable of being polymerized into an organic electrolyte by ultra violet irradiation, and
- developing said separator matrix on a glass board having a surface coated by at least one fluoroplastic material by irradiating ultraviolet ray through said glass board to polymerize said mixed solution to produce a separator matrix comprising an ionic conductive gel electrolyte.
- 3. A manufacturing method for producing a separator for a lithium secondary battery comprising the steps of:
- treating a microporous membrane comprising a polyolefin to produce a separator matrix having a surface which is lyophilic,
- impregnating said separator matrix with a solution comprising a resin capable of being polymerized by ultraviolet radiation and an organic electrolyte, and
- developing said impregnated separator matrix on a glass board having a surface coated with at least one fluoroplastic material by irradiating ultraviolet rays through said glass board to polymerize said solution to produce a separator matrix comprising an ionic conductive gel electrolyte.
- 4. A manufacturing method according to claim 3 wherein said polyolefin is selected from the group consisting of polyethylene, polypropylene, and combinations thereof.
- 5. A manufacturing method according to claim 3 wherein said treating step comprises contacting said microporous agent with a surface active agent.
- 6. A manufacturing method according to claim 3 wherein said treating step comprises oxidizing said microporous membrane by plasma irradiation.
