Abstract

本发明是一种采用直径0.05-0.5mm的铅（合金）纤维制成铅棉状，然后通过所需电池极板尺寸和形状的模具直接模压成各种电池的生极板，在经过10-40小时的适当化成和10周次以上充放电后，成为具有30wh/kg容量的电池极板。这就免除了铅酸蓄电池生产中铅板栅铸造、铅粉制造、铅膏配制、铅膏涂填、固化等一系列工序，避免了这些工序产生的污染，从而达到环保的效果。同时还具有低成本长寿命优点。

Description

一种环保型铅蓄电池及其制造工艺
技术领域
本发明涉及一种简单的具有环保效果的铅蓄电池及制造工艺。
技术背景
1859年G.Plante发明铅酸蓄电池时，是用两块铅板作正负极，在硫酸溶液中电解，电解电流方向不断变换，以在其表面得到更多活性物质，达到更大的电池容量，然而它无法实现实际应用。因为要生成1mm的活性物质，按此法需要一年时间。
后来，H.Tudor对它进行了改进，他把铅板制成有许多深槽的结构，使极板有效表面增加了6-10倍，提高了电池容量，从而该发明有了应用价值。至今通过许多改进的这种被称为“形成式”极板也称为Tudor式极板，还在某些特定场合得以应用。
真正使铅酸电池得以大规模应用的是在1881年C.Faure发明了涂膏式极板，其要点是用细铅（合金）粉与硫酸及其它添加物调和成膏体涂填在铅板表面。这样作为活性物质的铅粉大幅度提高了极板有效表面，从而达到大幅度提高电池容量的效果，这一发明使得铅酸蓄电池得以商品化，至今铅酸蓄电池成为在实用蓄电池中占据世界各国总产量和应用的第一位，其优势是绝对的，这种优势将保持相当长的时期。因为铅蓄电池具有原材价廉，资源丰富，生产工艺方便，市场成熟等优势。
百年来，为了与不断出现的新型蓄电池竞争，人们围绕着，提高能量密度，功率密度和充放寿命开展了大量研究，出现数以百计的发明，但人们忽略了铅酸蓄电池在现代环保理念上的突出问题。
目前，铅酸蓄电池在生产过程中污染严重的工序有铅板栅铸造，此工序产生铅烟尘，铅粉制造产生铅粉尘、生极板生产中的铅膏配制、铅膏涂填、及一系列干燥、固化等生产了含铅酸废水，它们都造成了环境污染。铅酸蓄电池生产和回收过程中造成的对环境污染正日趋严重。
发明内容
本发明采用直径为0.05-0.5mm的铅纤维制成铅棉状，在所需尺寸和形状的模具中直接压制成电池的正负极板，经化成工序、干燥后，在经10周次以上充放电后，达到额定容量的蓄电池。
所述用模具将铅纤维棉压制成的正负极板，是板状或管状。
本发明的优点在于，由于采用0.05-0.5mm的铅纤维制成铅棉状的正、负极板，这种极板的有效表面积大幅度提高，甚至于接近了涂膏式极板，其容量与膏极板相近，又由于用铅棉模压的极板没有板栅，因此不存在铅膏与板栅剥离、脱离的问题，因此，寿命长于膏极板，具有寿命长的优点。
由于本发明不用铸造铅板栅，不用制造铅粉，不用调制铅膏和涂填铅膏等一系列产生污染的工序，避免了生产过程污染，同时还节省了上述工序的投资，降低了生产成本。使铅酸蓄电池生产发生了革命性变革，铅酸蓄电池的生产和应用进入一个新时代。
