Description
Technical field
The utility model relates to a kind of battery diaphragm casting painting system, especially relates to a kind of full ceramic diaphragm casting painting system.
Background technology
In recent years, due to the finiteness of oil, colliery equal energy source, energy scarcity problem more and more obtains the attention of people, the product that new forms of energy public transport, motor-driven carrier etc. with lithium battery or lithium Fe battery have an environmental protection function in life by people are used; And present lithium battery or lithium Fe battery are when making, all battery positive and negative between be provided with one deck barrier film, this is to prevent lithium battery or lithium Fe battery to affect useful life of battery and the short circuit of battery the two poles of the earth due to self discharging and producing the problems such as battery explosion.The kind of barrier film is a lot, as weaved film, nowoven membrane (nonwoven fabrics), microporous polyolefin film, composite membrane, diaphragm paper, laminate etc., because microporous polyolefin film has excellent mechanical property, chemical stability and relatively inexpensive, the microporous polyolefin film such as polyethylene (PE) and polypropylene (PP) have been the main diaphragm material of lithium battery.In low capacity lithium battery or lithium Fe battery, adopt the polyalkene diaphragm of individual layer, bilayer and three layers, its fail safe is not all a problem.But, at Large Copacity, in particular for the electrokinetic cell of motor-driven carrier and electric bus, even adopt double-deck or three layers, even more multi-layered polyalkene diaphragm, still can not ensure its fail safe completely, this is because polyalkene diaphragm has the performance of thermal contraction, and high-capacity lithium battery can produce a large amount of heats when discharging, polyalkene diaphragm can be made like this to shrink and short circuit in battery, thus there is the hidden danger of the blast of lithium battery or lithium Fe battery.In addition, in order to improve the capacity of battery as much as possible in unit volume, be also the barrier film not allowing to adopt multilayer.In recent years, people improve original battery diaphragm abroad, invent a kind of ceramic diaphragm, it is the ceramic material layer being coated with one deck 1-2 μ in the side of the polyalkene diaphragm of 8-12 μ, using ceramic material layer as the skeleton of polyalkene diaphragm, prevent polyalkene diaphragm from shrinking when being heated and cause the positive and negative electrode direct short-circuit of battery, causing battery explosion.
But the ceramic diaphragm of above-mentioned improvement is mostly all coated ceramic size at the one or both sides of polyalkene diaphragm and made, the Main Function of ceramic size prevents microporous barrier from high temperature shrinking, and plays skeletal support effect.But, because ceramic material layer is 1-2 μ, and polyalkene diaphragm is 8-12 μ, wherein most of composition of microporous barrier or polyolefin, therefore, make battery diaphragm at a higher temperature in this way, microporous barrier still has shrinkage phenomenon, the particularly heat that produces when a large amount of electric discharge of high-capacity lithium battery, a large amount of heats still can make polyalkene diaphragm shrink in battery, make the positive and negative electrode direct short-circuit of battery in local, accelerate the electric discharge heat release of lithium battery or lithium Fe battery, thus the blast of lithium battery or lithium Fe battery may be made.
