电池隔膜纸
摘要
随着电池在人们生活中应用的重要性增加，高质量的电池生产越来越受到重
视，电池隔膜纸是电池性能的重要影响因素之一，高质量电池隔膜纸的生产就显激励短句
得尤为重要。电池隔膜纸是以化学纤维为原料，通常采用湿法造纸的方法生产的
一种特种纸，或者说是一种湿法无纺布的生产工艺。与传统的造纸比较，湿法无
纺布的生产有许多其特殊的工艺。又因为电池隔膜纸的特殊的亲水性要求，采用
化学纤维抄造的无纺布，往往要对其进行亲水化的处理。本论文对电池隔膜纸的
形容风景的诗句生产加工工艺做了一定的研究。
在对电池隔膜纸的生产过程中，化学纤维的分散往往采用较低的浓度，在
水介质中加人适量的分散剂及相应的消泡剂等助剂。最好在水介质中先加入分
散剂和消泡剂再加人化学纤维，以促进纤维更好的分散效果，尽量减少分散好
的纤维的转移次数和存储时间，并保证浆料输送管道的光滑性减少挂浆。
化学纤维间不存在类似植物纤维的氢键等结合键，只有纤维相互交织在一
起，因而，在形成的纸页纤维间没有结合力，导致纸页强度极低，或者说根本
不存在强度。采用皮芯结构的低熔点纤维，在一定的热压条件下，皮层纤维熔
化，纤维间相互粘结，提高纸页的强度。
采用分裂纤维和低熔点纤维抄造纸页，纤维配比的改变对纸页的吸收及强
度性能有很大的影响。改变纸页的结构，采用三层抄造纸页的方法，纸页综合
性能的提高。采用面层为100%的低熔点纤维，芯层为40%低熔点纤维与60%分
裂纤维的配比抄成的纸页，其性能能够满足电池隔膜纸的要求，由于部分分裂
纤维的溶出，导致纸页的碱溶出率较高，只适合于质量较低的电池的生产。

Study on High Performance Battery Separator of MH-Ni Battery
Abstract
As the increasing usage of the battery in daily life, people pay more attention
on high capability battery. And so, the technology of battery producing has been
advanced. The battery parator is located between the positive plates and
negative plates so as to provide a paration between the electrodes of opposite
charge and an electrolyte rervoir. So the battery parator is one of the most
important factors that influence battery capability. Constituted chemical fibers,
the battery parator generally produced by wet一laid process. The production is

kind of special paper or wet一laid nonwoven. Compared with traditional paper
manufacturing process, wet一laid process production of chemical fibers has many
special manufacture methods. High required of hydrophilic character, the battery
parator made from chemical fibers need to be treated to hydrophili亡.The
production method of the battery parator was studied in this paper.
The consistence of the stock of chemical fibers should be less than that of the
plant fibers，and the dispersion and the deformer should be employed to the stock.
We found that it better to add the additives into the water before the addition of
the fibers.It should decrea the times of the transfer of the stock and ensure the
lubricity of the stock piping.
The hydrogen bonds，which exist in plant fibers paper, don't exist in the
paper that made by chemical fibers. There is only interweavement of chemical

fibers, so that, the tensile strength of the nonwoven fabric is very poor. The paper
adopt the hot-melt fibers(ES fibers) which is sheath一core structure, at a certain
pressure and temperature, the sheath of the fiber was melted and the fibers fud
together, so that, the tensile strength of the paper is advanced.
The paper is made by the dividable composite fibers(DCF) and ES fibers, the
proportioning of the two kinds of fibers effects the absorption and tensile strength
of the paper distinctly. We elevae the allround performance of the paper by
changing the structure of the paper, the experiment proved that the three一layers
structure paper is functional. The paper, the face一layers of which are made by ES
fibers and the core一layer is made by 40% ES fibers and 60% DCF, has a better
performance, and it fits for the production of the battery. But the alkali stripping
ratio of the paper is a little high.
It is better producing the high performance battery parator by 100% ES
fibers. Being hydrophobic, the ES fibers paper should be treated to hydrophilic.
The usual hydrophilic treating methods are strong oxidizer treatment, strong
acid一potassium dichromate treatment and plasma treatment. It is proved that the
three hydrophilic treating methods are all efficiency. Every method has its own
merit, and the one fitting the circumstances should be lected.
