黑色铝塑膜和聚合物锂电池Black aluminum plastic film and polymer lithium battery 技术领域Technical field
本发明涉及聚合物锂电池技术领域，具体涉及用于包覆聚合物锂电池的电解液的黑色铝塑膜及采用该黑色铝塑膜的聚合物锂电池。The present invention relates to the field of polymer lithium battery technology, and in particular to a black aluminum plastic film for coating an electrolyte of a polymer lithium battery and a polymer lithium battery using the black aluminum plastic film.
背景技术Background technique
锂电池根据所用电解质材料不同分为液态锂电池和聚合物锂电池两大类，液态锂电池的电解质材料采用液体电解液，聚合物锂电池的电解质材料采用胶态聚合物电解液。聚合物电池是新型电池，与液态锂电池相比具有能量密度高、小型化、超薄化、轻量化、以及高安全性等多种明显优势。Lithium batteries are classified into two types: liquid lithium batteries and polymer lithium batteries according to the electrolyte materials used. The electrolyte materials of liquid lithium batteries use liquid electrolytes, and the electrolyte materials of polymer lithium batteries use colloidal polymer electrolytes. Polymer batteries are new types of batteries, which have many advantages such as high energy density, miniaturization, ultra-thinness, light weight, and high safety compared with liquid lithium batteries.
国内聚合物锂电池多为软包电池，采用铝塑膜作为外壳对胶态聚合物电解液进行封装，这样设计的好处主要有以下两点：第一，使聚合物锂电池相对于液态锂电池更加超薄化和轻量化；第二，在安全方面，当聚合物锂电池的胶态聚合物电解液沸腾时，铝塑膜会自然鼓包或破裂，不会爆炸。Domestic polymer lithium batteries are mostly soft-packed batteries, which use aluminum plastic film as the outer casing to encapsulate the colloidal polymer electrolyte. The advantages of this design are mainly as follows: First, the polymer lithium battery is compared with the liquid lithium battery. More ultra-thin and lighter; Second, in terms of safety, when the colloidal polymer electrolyte of the polymer lithium battery boils, the aluminum plastic film will naturally bulge or rupture without exploding.
尽管铝塑膜赋予了聚合物锂电池诸多优良性能，但现有铝塑膜仍存在以下缺陷：Although the aluminum plastic film imparts many excellent properties to the polymer lithium battery, the existing aluminum plastic film still has the following defects:
第一，现有铝塑膜产品外观设计单一且文字的突显性受限制，现有铝塑膜主要由透明的流延聚丙烯薄膜、透明的聚酰胺纤维、透明的胶黏剂和铝箔组成，因而从外观上，铝塑膜显现出来的是铝箔本身的颜色，故印刷在铝塑膜表面的表征产品信息的文字颜色如为白色及其他浅色系时，其外观突显性较差，使得铝塑膜的外观设计不够丰富。First, the existing aluminum-plastic film products have a single design and the conspicuousness of the characters is limited. The existing aluminum-plastic film is mainly composed of a transparent cast polypropylene film, a transparent polyamide fiber, a transparent adhesive and an aluminum foil. Therefore, from the appearance, the aluminum plastic film shows the color of the aluminum foil itself, so when the character color of the product information printed on the surface of the aluminum plastic film is white and other light colors, the appearance of the aluminum foil is poor, so that the aluminum is poor. The design of the plastic film is not rich enough.
第二，现有铝塑膜的原材料初始爽滑性一般较好，但随铝塑加工工艺中工艺温度的需求，使得成品铝塑膜的爽滑性变差。爽滑性差导致铝塑膜冲型深度较低，生产过程中的良频率较低。进而导致铝塑膜在包覆电解液的容量较小，且受良品率过低影响使得制造成本加大。Secondly, the initial smoothness of the raw materials of the existing aluminum plastic film is generally good, but the smoothness of the finished aluminum plastic film deteriorates with the demand of the process temperature in the aluminum plastic processing process. The poor slipperiness results in a lower depth of the aluminum-plastic film and a lower frequency in the production process. Further, the aluminum plastic film has a small capacity for coating the electrolyte, and the manufacturing cost is increased due to the influence of the low yield.
第三，现有铝塑膜的耐化性或耐药品性差，由于铝塑膜用于包覆聚合物锂电池的电解液，耐化性或耐药品性差的缺陷直接导致采用该铝塑膜的聚合物锂电池的使用寿命大大降低。Thirdly, the existing aluminum plastic film has poor chemical resistance or chemical resistance. Since the aluminum plastic film is used for coating the electrolyte of the polymer lithium battery, the defects of chemical resistance or chemical resistance directly lead to the use of the aluminum plastic. The service life of the polymer lithium battery of the membrane is greatly reduced.
基于以上三个缺陷，铝塑膜作为封装聚合物锂电池的关键材料，急需解决上述问题。Based on the above three defects, aluminum plastic film is a key material for encapsulating polymer lithium batteries, and it is urgent to solve the above problems.
发明内容Summary of the invention
本发明实施例的目的在于针对现有技术的不足，提供一种具有较好的爽滑性、较好的耐化性、较好的文字突显性和文字颜色多变性的黑色铝塑膜。The purpose of the embodiments of the present invention is to provide a black aluminum plastic film with better smoothness, better chemical resistance, better text sharpness and text color variability in view of the deficiencies of the prior art.

In short, as long as the aluminum plastic film is provided with a black layer containing carbon black, the printed text has both sharpness and color variability, and the outer surface of the black aluminum plastic film has smooth characteristics, thereby improving the yield of the aluminum-plastic film. It can also enhance the chemical resistance of black aluminum plastic film, thus prolonging the service life of polymer lithium battery.

At least one of the agent layer, the aluminum foil layer and the polyamide fiber layer is a black layer, wherein: the black adhesive layer is a uniform mixture of the adhesive and the black nano-carbon black after high pressure, centrifugation and crushing. Black layer.
需要特别强调的是，黑色的胶黏剂层的贡献突出，除了上述提及的优良的爽滑性和耐化性外，其可贵之处在于，克服了现有技术中难以将纳米级炭黑均匀分散于胶黏剂层的困难，经发明人的多次实验和研究，通过将胶黏剂和纳米级炭黑的混合物依次经过高压、离心和破碎后才制成均一的黑色层。It is particularly emphasized that the contribution of the black adhesive layer is outstanding, and besides the excellent smoothness and chemical resistance mentioned above, it is valuable in that it is difficult to overcome the nano-scale carbon black in the prior art. The difficulty of uniformly dispersing in the adhesive layer has been made into a uniform black layer by subjecting the mixture of the adhesive and the nano-scale carbon black to high pressure, centrifugation and crushing in turn by the inventor's many experiments and studies.
此外，采用干法工艺，通过胶黏剂层，将流延聚丙烯薄膜层或聚酰胺纤维层与铝箔层粘接。这种粘接为铝箔层的单面或双面粘接。干法工艺使得黑色铝塑膜的冲深成型性能、防短路性能和裁切性能更优良。Further, a cast polypropylene film layer or a polyamide fiber layer is bonded to the aluminum foil layer by a dry process through an adhesive layer. This bonding is one-sided or double-sided bonding of the aluminum foil layer. The dry process makes the black aluminum plastic film more excellent in deep forming performance, short circuit prevention performance and cutting performance.
更进一步的，黑色铝塑膜在包括胶黏剂层的基础上，还包括胶黏树脂层，流延聚丙烯薄膜层和聚酰胺纤维层中的一层通过胶黏剂层与铝箔层粘接，流延聚丙烯薄膜层和聚酰胺纤维 层中的另一层通过胶黏树脂层与铝箔层粘接。Further, the black aluminum plastic film further comprises an adhesive resin layer on the basis of the adhesive layer, and one of the cast polypropylene film layer and the polyamide fiber layer is bonded to the aluminum foil layer through the adhesive layer. , cast polypropylene film layer and polyamide fiber The other layer in the layer is bonded to the aluminum foil layer by an adhesive resin layer.
