Abstract
本发明涉及用于制造软包装锂电池或聚合物锂电池的隔膜粘接胶，该粘接胶由丙酮、聚四氟乙烯以及环氧树脂制成的，其中各原料组份的重量百分比含量为，丙酮78-90%，聚四氟乙烯3-15%，环氧树脂3-12%。本隔膜粘接胶具有用量少、价格低廉、制作工艺简单及使用方便优点，并且能快速地把隔膜融合，使外层隔膜固定处平整，无厚度差，且不与电池内部其他化学物质发生化学反应等特点，粘接效果好，能够广泛地用于液态软包装或聚合物锂电池。The present invention relates to the diaphragm adhesive glue that is used for manufacturing flexible packaging lithium battery or polymer lithium battery, and this adhesive glue is made of acetone, polytetrafluoroethylene and epoxy resin, wherein the weight percentage content of each raw material component is, Acetone 78-90%, polytetrafluoroethylene 3-15%, epoxy resin 3-12%. The diaphragm adhesive has the advantages of less consumption, low price, simple manufacturing process and convenient use, and can quickly fuse the diaphragm, so that the fixed part of the outer diaphragm is flat, there is no difference in thickness, and it does not interact with other chemical substances inside the battery. Chemical reaction and other characteristics, good bonding effect, can be widely used in liquid flexible packaging or 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.
