A cathode and an anode are oppositely arranged with a separator in between. The open circuit voltage in full charge is in the range from 4.25 ... 07/20/06 - 20060159999 - Method of automated prismatic electrochemical cells production and method of the cell assembly and construction The present invention pertains to electrochemical devices having a thin micro porous polytetrafluoroethylene separator bonded to their porous electrodes without special treatment of the separator and without additional adhesive layers. Structures of superior high energy density and power density are disclosed herein, as well as the methods of their assembly ... 07/06/06 - 20060147804 - Separator material and method of producing the same, and alkali secondary battery separator A separator material of the present invention is a sulfonated nonwoven that comprises a polyolefin ultra-fine short fiber having a fineness of less than 0.5 dtex and other polyolefin short fiber(s). The other polyolefin short fibers include a polyolefin thermal bonding short fiber. At least a portion of the polyolefin ... 04/06/06 - 20060073389 - Separator for battery and lithium ion battery using the same A battery separator of the invention is obtained by press forming a meltblown nonwoven fabric comprising 4-methyl-1-pentene polymer or a 4-methyl-1-pentene/α-olefin copolymer, the battery separator having an average fiber diameter of 0.8 to 5 μm, a basis weight of 9 to 30 g/m2, a porosity of 30 to 60%, and ... 11/24/05 - 20050260499 - Thermoplastic separator for alkaline electrochemical cells and processes for the production thereof An alkaline electrochemical cell containing a neat multiphase thermoplastic polymer separator is disclosed. The microstructure and composition of the polymer are selected to provide a film that can physically endure the rigors of a cell assembly process and also provide adequate ionic conductivity to support a high rate discharge. In ... 11/03/05 - 20050244717 - Battery separator with antistatic properties A battery separator comprising: a microporous polyolefin film having from 0.1% to 50% by weight of a block copolymer including a polyetheresteramide monomer. In this battery separator the polyolefin is selected from the group consisting of: polyethylene, polypropylene, polybutylene, polymethylpentene, mixtures thereof, and copolymers thereof. Preferably the polyolefin is polyethylene, ... 10/27/05 - 20050238962 - Separators for winding-type lithium secondary batteries having gel-type polymer electrolytes and manufacturing method for the same A porous separator for a winding-type lithium secondary battery having a gel-type polymer electrolyte includes a matrix made of polyvinyl chloride, or a matrix made of mixtures of polyvinylchloride and at least one polymer selected from the group consisting of polyvinylidenefluoride, a vinylidenefluoride/hexafluoropropylene copolymer, polymethacrylate, polyacrylonitrileand polyethyleneoxide. ... ### FreshPatents.com Support |
