The invention relates to a composite gel polymer Li-ion battery and its producing method. The Li-ion battery cell includes a three-layer composite layer of positive electrode current collector, positive electrode active material and gel polymer electrolyte obtained by a two-layer one-step coating process; a two-layer composite layer of negative electrode current collector and negative electrode active material obtained by a single-layer coating process or a negative electrode two-layer composite layer coated with a little polyurethane adhesive(s) on the surface. The gel polymer Li-ion battery cell is obtained by laminating the resultant two composite layers. Its producing method includes: A) coating directly the composite positive electrode current collector film which has a bottom layer of polyester and a surface layer of metal (aluminum, copper, silver or gold) foil with a positive electrode active material and a gel polymer electrolyte by a two-layer one-step coating process; B) coating the composite negative electrode current collector film which has a bottom layer of polyester and a surface layer of metal (aluminum, copper, silver or gold) foil with a Li battery negative electrode active material; C) laminating A and B layers, heating and curing, leading out electrode lugs, and thereby obtaining gel polymer Li-ion battery cells; D) vacuum-packing the battery cells, and thereby obtaining a gel polymer Li-ion battery. The gel polymer Li-ion battery cell has a small thickness and a compact structure, and is laminated closely and easy for preparation and industrial automatic production. And a plurality of groups of cells can be laminated and cut to a desirable geometrical shape, so as to obtain a Li battery pack in a desired shape. The Li battery prepared by the method has a uniform structure, a low internal resistance, a high uniformity, a good unity, and a high safety.

摘要:
A method and system to use a standard cell function library to automatically configure gate array cells in an integrated circuit layout is provided. A standard cell netlist at the transistor level is compiled to list the transistors required in implementing the desired functions. Based on the netlist, gate array cells are restructured so that they can be inserted in locations designed for standard cells. The restructured gate array cells, which are made up of single poly and double poly structures, are strategically placed in a layout. Using the function net connectivity patterns from the standard cell function library, the gate array cells are connected to implement desired logic functions.
