Description
技术领域
本发明涉及一种具有至少一个锂掺杂(lithium-intercollating)电极和有机电解质的电化学电池的制造方法。
背景技术
在可充电4V电池形式的、有锂掺杂电极的电化学电池中，隔板担负着许多艰巨任务。当电池处于满荷状态时，电压通常为4.2V，通常由碳形成的负极的锂活度接近于一(unity)，即意味着，虽然活性材料是一种改良碳，但满荷状态的电池的还原电位几乎与金属锂的还原电位相当。在阳极侧，通常用锂过渡金属氧化物作活性材料。当电池满荷状态时，产生只有少数物质能经受得起的很高的氧化电位。而且，满荷状态电池的稳定性即使在升高温度的不利条件下，至少在短期内不会受到不利影响，在本文中温度必须高达90℃和时间至少为两个小时或以上。
因此，例如，由聚丙烯(PP)、聚乙烯(PE)或者由这些原料的两层或更多层构成的聚烯烃隔板常用在可充电锂电池中。由于单轴或者双轴拉伸，隔板需有容纳电解液的孔隙结构和例如倘若在电池内部偶然短路或者以任何其他的方式引起的温度升高，利用熔点在大约120℃的PE可熔化这些气孔，从而导致所谓的关闭效应。因为气孔封闭意味着隔板中电解液不再具有任何导电性，所以内阻急剧升高。
专利文件EP0951080B1公开了一种电池隔板，其具有第一和第三微孔层，和在它们之间有关闭能力的第二微孔薄膜，其中的多孔薄膜是用伸展法制造的。
然而，在实践中已经发现其效果不一定总是可靠。倘若出现非常短的和剧烈的升温，该关闭机理在某些环境下可能不起作用。例如特别是在用锋利的导电物体从外部捅入电池时，和倘若电池过量充电时，可能发生急剧的升温。关闭机理的负面效果与聚烯烃隔板在熔化期间收缩有关。突然的能量增加越大越强，收缩过程就越强，这不仅导致气孔关闭，还因不利方式的收缩使整个隔板崩溃以致于电池短路并且反应更加强烈，形成火焰。为使隔板里产生气孔而采用单轴或者双轴拉伸方法在这种情况下可能也会产生不利的影响，因为如同由于惯性使得弹簧在伸展方向收缩一样，隔板以收缩形式崩溃与其生产过程有关。尤其对于大容量锂电池，例如用作车辆动力供应系统或牵引用的42伏特电池，解决上述隔板问题是必需的。
专利文件EP1096591A1公开了一种凝胶状的隔膜，其粘合剂聚合物选自聚丙烯腈，聚甲基丙烯酸甲酯，聚氯乙烯，聚乙烯砜，聚乙二醇二丙烯酸脂，聚乙烯基吡咯烷酮，聚偏二氟乙烯或者它们与选自Al2O3，SiO2，TiO2，ZrO2的陶瓷材料的或者它们混合物的混合物。
专利文件EP1043795A2公开了一种复合电极，其由一种活性电极材料，一个电导率增强器，一种聚合物电解质和一种天然存在的矿物固体电解质组成。
专利文件US6,057,061公开了一种电池隔板，具有一层取向的微孔膜，其含有乙烯-乙烯醇和选自玻璃陶瓷，聚四氟乙烯(PTFE)或者具有类橡胶特性的缩合塑料颗粒的化学性质呈惰性的填料。
专利文件EP1011157A2公开了一种可充电锂电池隔板材料，采用聚偏二氟乙烯六氟丙烯作为粘合剂，隔板中分散有较高软化温度的颗粒。
专利文件DE19916109A1公开了一种适于在电化学电池中用作隔板的复合体，其具有含有至少一种固体的至少一层第一层，是施加到至少一层由常规的隔板材料组成的第二层上。
专利文件DE20010080U1公开了一种固体离子导体基的可充电电池，在正、负电极之间设有固体电解质，负极也由碳纳米结构组成。
发明内容
本发明的目的是以特定方法制造有防火特性的电化学电池，这种电池阻止由于电池在短期内的急剧升温导致的隔板收缩的危险和阻止电池爆炸燃烧，同时隔板又有较好的离子电导率。
本发明的目的通过开始述及的方法的权利要求1的区别技术特征实现。本方法的更详尽的步骤如从属权利要求所述。
由于晶格结构缺陷和特别是在晶粒表面上的表面缺陷的结果导致每种锂盐都有它固定的离子电导率。如果含有固体陶瓷锂盐的隔板被锂电解液浸渍，其锂盐是分散在聚合物粘合剂中的，那么单个的电导率σ累计如下：
σ总＝σ离子，固态+σ离子，表面+σ离子，液态
与只能通过充满电解液的孔获得总电导率的惰性聚烯烃隔板相比，优点在于隔板总的离子电导率增加。为了获得有尽可能低接触电阻的晶粒表面，优选使用d50分布值为1μm左右的晶粒。此值可用一般的研磨方法获得。每当可以对液体辅助电解质或者电极形成固-液相界面时，就可以用特别有效的方法使用固体离子导体。
而且，作为陶瓷填充物重要的特性，必须有一个对于还原和氧化反应有较宽电化学稳定性的范围，没有或有极低的潮解性，和材料成本低。在最初提到的条件下，只有少数化合物是稳定的，一方面锂活性接近于一(unity)和另一个方面锂有超过4V的氧化电位。稳定性范围使元素限于少量的优选主族元素，例如硼，铝，硅，磷，氮，氧和氟。这也说明高电子绝缘能力是必要条件，其产生的电子残余导电性至少小于10-10S/cm。过渡金属，或高价元素，与纯离子导电不同，可以通过同时吸附电子，导致电导率暴增两个或多个数量级。陶瓷锂离子导体例如Li5AlO4，Li4SiO4有0-5.5V宽的稳定性范围，不过制造昂贵且极易吸湿。因此，根据本发明，要用大量存在的天然和有可接受纯度的同时既不吸湿又不昂贵的化合物。盐的实例为，例如锂磷铝石，锂云母，透锂长石和，作为最常见的和最主要的锂矿物，锂辉石，LiAlSi2O6。LiAlSi2O6作为形成玻璃的物质也有其重要的优势，同样可以将其作为极好的关闭材料。当其温度到达形成玻璃的温度时，填充量达到至少60％(重量)和优选至少75％(重量)的大量的陶瓷材料液化。在这种情况下，不必担心像在聚烯烃隔板情况下发生的自发收缩。而且，陶瓷组分增加了安全性，因为倘若误用时，更多的惰性材料可以用来熄灭火焰。陶瓷隔板是主要优点，特别在使用一种过量充电添加剂时，因为它可以用极有利的方式进一步增强后者好的特性。
填充量与没有溶剂时称重全部组分时的状态有关。为了提供具有韧性的薄片和小于150℃的软化温度，优选用共聚物作为粘合剂。适当的材料是聚偏二氟乙烯六氟丙烯共聚物，PVDF-HFP，其HFP组份为5-8％。为了取得有利的孔隙结构，配方中可以加入增塑剂，然后在填充满前用有机电解液洗去。
过量充电添加剂的实例为3，5-二氟苯甲醚，1，3，5-三甲氧基苯，2-甲氧基乙醚，三甘醇二甲醚，四甘醇二甲醚，1，2，4-三氟苯，联苯，1，2，3，4-四氟苯，2，4，6-三甲氧基嘧啶，2，6-二甲氧-1，4-苯醌和2，4-二甲氧基苯腈。这些添加剂的作用机理明显基于优选环状构造的依赖于电压的崩溃，其中这些碎片聚合有机电解质或者引起阴极表面钝化。如果在锂离子电池中因为有许多电化学优点，含有LiCoO2-LiCoO2的电极而成为标准材料，和聚烯烃隔板过量充电，那么电池在大约4.8V或以上的电压下处于临界状态，也就是说它即将热失控和突然着火。过量充电添加剂在此电压范围分解，而分解产物在瞬间抑制住电池内部的电流。如果选定的添加剂的分解电压太低，则也将在标准的电池工作中产生消极影响。陶瓷隔板现在可以有效地使如上所述的4.8V的临界电压增加数个100mV，因此可以使用过量充电添加剂，其中分解电压越高越好。添加剂的一个实例是1，2，4-三氟苯，其分解电压大约为5.2V左右，这对于4.2V电池的标准最大充电电压大约有1V的缓冲区。
实施例：
在3升丙酮中将2887g的球状石墨与82g的导电的炭黑，371g的聚合物粘合剂(聚偏二氟乙烯六氟丙烯)和859g的邻苯二甲酸二丁酯充分混合，将上述混合产物铺展在聚酯基片上，使之干燥，来制造负极(阳极)的浆状物质。
在2.5升丙酮中将3150g的锂辉石，336g的聚合物粘合剂和336g的邻苯二甲酸二丁酯充分混合，将上述混合产物铺展在聚酯基片上，使之干燥，制造隔板的浆状物质。
在4.8升丙酮中将2819g的LiCoO2，198g的导电的炭黑，297g的聚合物粘合剂和495g的邻苯二甲酸二丁酯充分混合，将上述混合产物铺展在聚酯基片上，使之干燥，制造正极(阴极)浆状物质。
负极被模压成8.50×6.05cm2的片并在130℃，以30kg压力层压到带有输出导体接线片的铜输出电极两侧。在110℃和压力为10kg条件下，隔板以伸出的方式被层压在用这种方法制造的负极上。正极被模压成8.35×5.90cm2的片并在140℃和接触压力为20kg条件下，层压到带有输出导体接线片的铝伸展金属板上。在这种情况下为了增进电极粘附性，用粘附层(底层)预处理铝伸展金属板。在120℃和压力为10kg条件下，用这种方法获得的阴极被层压到隔板阳极组件的两侧上，切掉伸出的隔板边缘，仅剩下很小的伸出部分。此后，用溶剂冲洗双电池(bicell)的邻苯二甲酸二丁酯增塑剂，以便产生供电解质进入的充足的孔。用超声波将五个这样的双电池(bicell)焊接到输出导体接线片，负极侧面上是固态镍输出导体，正极侧面上是铝输出导体，用两侧经涂敷的热成型铝板包装这样制得的电池组件，并用大约7毫升的有机锂电解液进行活化。
用这种方法制造的满荷电池(4.2V)比按可比较的方式用聚烯烃隔板制造的电池在用锋利的导电物体捅入时反应更温和。当根据上述实施例制造的电池在12V和1C(大约1.5A)过量充电时，其反应仅仅冒烟和放出气体，而用聚烯烃隔板制造的可比较电池将完全燃烧放出大量的热和火焰。
附图说明
图1显示根据实施例1生产的电池的电容C作为循环数n的函数。在恒定电流值1C(1.5A)条件下电池充电至4.2V，电压保持3小时，然后电池在1C(1.5A)条件下放电到3.0V。用这种方法获得的曲线上的点表明用这种方法生产的电池有很高的可靠性。
