Abstract
The present invention relates to diaphragm adhesive glue for liquid soft packages and polymer lithium batteries, which is composed of acetone, polytetrafluoroethylene and epoxy resin, wherein the weight percentage content of each raw material component is 78 to 90% of acetone, 3 to 15% of polytetrafluoroethylene and 3 to 21% of epoxy resin. The present invention has the advantages of little consumption, low price, simple preparation process and convenient operation, the present invention can rapidly combine diaphragms, and outer layers have the characteristics of smooth diaphragm fixing point, no thickness difference, no chemical reaction with other chemical substances in batteries, etc. The present invention has the advantages of good adhesive effect and can be widely used in the liquid soft packages or the polymer lithium batteries.
Description
Technical field
The present invention relates to the bonded adhesives technology, specifically is a kind of diaphragm binding glue that is used to make flexible package lithium cell or poly-lithium battery.
Background technology
In recent years, the range of application of liquid flexible packing or poly-lithium battery is more and more wider, and market is also more and more stricter to its quality requirement.Traditional electric core winding generally adopts gummed paper fixation ends barrier film or pole piece, also has barrier film, pole piece end fixing etc.The employing gummed paper is fixed, because gummed paper itself has certain thickness, so cause the out-of-flatness of battery outward appearance, cell thickness is unequal, in addition, introduces gummed paper and causes easily that the internal resistance of cell is big, self discharge is big.If barrier film or pole piece end are unfixing, then can influence the tightness of electric core, when vacuumizing soldering and sealing, easily diaphragm paper or pole piece are siphoned away off normal, thereby influence battery outward appearance and battery performance.
Summary of the invention
For avoiding the prior art above shortcomings, the invention provides a kind of easy to use, the liquid flexible packing lithium battery that adhesive effect is good or the diaphragm binding glue of poly-lithium battery.
The present invention is used to make the diaphragm binding glue of flexible package lithium cell or poly-lithium battery and is made by acetone, polytetrafluoroethylene and epoxy resin, wherein the weight percent content of each material component is, acetone 78-90%, polytetrafluoroethylene 3-15%, epoxy resin 3-12%.
Diaphragm binding glue of the present invention has that consumption is few, cheap, manufacture craft simply reaches advantage easy to use, and can merge barrier film apace, make outer diaphragm bearing smooth, no thickness difference, and not with characteristics such as other chemical substance generation chemical reactions of inside battery, adhesive effect is good, can be widely used for liquid flexible packing or poly-lithium battery.
