Description
Technical field
The present invention relates to lithium battery diaphragm combination machine equipment technical field, refer in particular to a kind of lithium battery diaphragm combination machine here.
Background technology
In the structure of lithium cell, barrier film is one of interior layer assembly of key, the performance of barrier film determines the interfacial structure, internal resistance etc. of battery, directly affects the characteristics such as the capacity of battery, circulation and safety performance, and the barrier film of excellent performance has important effect to the Combination property improving battery.Barrier film adopts plastic film to make, and can isolate battery plus-negative plate, to prevent short circuit; When battery is overheated, the electric current conduction in battery can also be intercepted by closed pore function.The description of the popular point of barrier film is exactly the plastic sheeting of one deck porous, it is a kind of high added value material that in lithium electric material, technology barriers are the highest, account for the 20%-30% of lithium cell cost, the major cause that barrier film holds at high price be some gordian techniquies making barrier films by Japan and the U.S. monopolize, the index of domestic barrier film particularly high-end barrier film does not also reach the level of external product.
Membrane technique difficult point is engineering branch art and the basis material of pore-creating.Wherein the engineering technology of pore-creating comprises barrier film pore-creating technique, production facilities and product stability.The basis material of barrier film comprises poly-third bright, polythene material and additive.Current barrier film production technology can be divided into two large classes according to dry method and wet method, and dry method can be subdivided into unilateral stretching technique and stretch processes again simultaneously.Dry method unilateral stretching technique is the method by producing hard elastic fibre, prepares high oriented polypropylene or the polyethylene foil of low-crystallinity, obtains the oriented film of high-crystallinity at high temperature annealing.This film first carries out stretching at low temperatures and forms microdefect, then makes defect pull open, form micropore under high temperature.This technique is very ripe in the U.S., Japan through the development of decades, and this technique needs that equipment is very complicated, equipment precision requirement is very high, and whole technique is quite complicated, controls difficulty high.The diaphragm micro-hole produced requires that size, distribution are all very even, and micropore conduction is good, can produce the barrier film of different-thickness, and PP, PE material can be adopted to produce.Because gordian technique rests in Japan and u s company, domestic manufacturer does not also grasp this technique, does not therefore also process the specialized equipment of this product.
Wet method is also known as phase separation method or thermally induced phase separation.Mix with polyolefin resin by high boiling hydrocarbon liquids or the low point material in amount, heat and dissolve solvate and melt is layered on thin slice, then lowering the temperature is separated, then with longitudinal direction or black soy sauce to time thin slice do orientation process.Finally with highly volatile solvent extraction liquid.Mutually through microporous membrane material can be prepared.Owing to have passed through biaxial tension, there is higher vertical and horizontal intensity with the barrier film that wet method bidirectional extending method is produced.Be mainly used in the PE barrier film of individual layer at present.This technique needs equipment, and also very complicated, whole technological process is quite complicated, and cost is high, energy consumption is large, but the diaphragm micro-hole size produced, distributes very evenly, and micropore conduction is good, easily produces thinner barrier film, and PE material can be adopted to produce.
At present, domestic employing barrier film processing technology is stretch processes, by adding the crystal formation improver with nucleation in polypropylene, utilize the difference of density between polypropylene different phase, in drawing process, there is crystal transfer form micropore, for the production of individual layer PP film, or common PP blow molding process is adopted to process.As a complete unit, the battery diaphragm of domestic production, pore size, distribution all comparatively uneven, and poor stability, in order to reach comparatively uniform micropore, usual way is that laminated diaphragm is carried out compound, can obtain thicker battery diaphragm, can arrive the basic demand of battery diaphragm technology, in can meeting, low side battery production needs.
Barrier film carries out compound, specialized equipment compounding machine need be adopted to unreel, roll-in, rolling.At present, lithium battery diaphragm combination machine on market, can not realize laminated diaphragm and carry out compound, and unreeling in process, its card unreels axis can only single clamping paper web or work durm, in use, what may need to change work durm or paper web unreels axis, can produce a lot of inconvenience during use; When roll-in and rolling, and in nipping process, barrier film is easy to wrinkling, gassing, processes barrier film planeness poor, can not meet the requirement of battery diaphragm.
