Abstract

本发明公开了一种铅碳蓄电池专用正极铅膏，它由下列按重量百分比计量的组分构成：铅粉85～88%、硫酸5.0～8.0%、水6.5～8.5%、碳纤维0.1～0.2%。本发明中的碳纤维是导电碳纤维，在正极铅膏中掺入导电碳纤维，既增加正极铅膏与板栅的附着力，又显著减少内阻，并且大大增加导电能力，另外，容量循环寿命也比现有技术的普通铅酸蓄电池循环次数至少提高3000次以上。

Description

铅碳蓄电池专用正极铅膏
技术领域
本发明属于蓄电池用铅膏，具体地讲，本发明涉及一种蓄电池用正极铅膏，特别是一种铅碳蓄电池专用正极铅膏。
背景技术
铅碳蓄电池是一种在铅酸蓄电池基础上发展起来的一种新型蓄电池，其主要性能均好过铅酸蓄电池，特别是大电流放电能力和充电接受能力。另外，铅碳蓄电池的内阻相对较小，由此可延长蓄电池的使用寿命。铅碳蓄电池获得上述性能提升的基础之一是内置正极铅膏组分的改善。铅膏是一种多元混合体，是电化学反应不可缺少的载体。市售铅碳蓄电池配置的正极铅膏，普遍在铅酸蓄电池的正极铅膏配方基础上改进配制而成。虽然大电流充放电能力有所提升，但仍然不能满足不间断电源瞬时大电流的配套要求。经分析研究，仍然存在正极铅膏中的正性物质利用率偏低问题，以及内阻值偏大，直接导致大电流充放电不畅，从而降低铅碳蓄电池的使用寿命。
发明内容
本发明主要针对现有技术的不足，提出一种组分合理、配置容易、内置正性物质利用率高，导电能力强的铅碳蓄电池专用正极铅膏。
本发明通过下述技术方案实现技术目标。
铅碳蓄电池专用正极铅膏，其改进之处在于：它由下列按重量百分比计量的组分构成，铅粉85～88%、硫酸5.0～8.0%、水6.5～8.5%、碳纤维0.1～0.2%。
作为进一步改进方案，所述硫酸的密度为1.35g/cm3。
作为进一步改进方案，所述水为去离子水。
作为进一步改进方案，所述碳纤维为导电碳纤维。
本发明与现有技术相比，具有以下积极效果：
1、组分少，配置容易；
2、正极铅膏中掺入导电碳纤维，既增加正极铅膏与板栅的附着力，又显著减少内阻，并且大大增加导电能力；
3、板栅上涂附富含导电碳纤维的正极铅膏，为大电流充放电创造了基础条件。
附图说明
图1是充电接受能力测试数据转换图表。
图2是铅碳蓄电池与普通铅酸蓄电池容量循环寿命90%～30%对比曲线。
具体实施方式
下面通过实施例来进一步说明本发明。
为了进一步验证本发明，现通过实施例来配制铅碳蓄电池专用正极铅膏，具体组分见下表：
取用上表中三项实施例制成的正极铅膏制造500Ah的铅碳蓄电池，然后按GB22473-2008《储能铅酸蓄电池》第7.5条，作充电接受能力测试，具体测试数据为三项实施例平均数据。
充电接受能力测试数据汇总表
从表中可知，应用本发明的产品充电接受能力比现有技术产品有显著性提高。现将上表中的数据转换成图表，可清楚地看到现有技术产品与本发明的差别，具体内容见附图1。
容量循环寿命是考核铅碳蓄电池质量的重要指标之一，应用本发明制成的产品和现有技术产品在同一测试条件下进行测试，具体测试结果见《容量循环寿命对比表》和附图2所示的铅碳蓄电池与普通铅酸蓄电池容量循环寿命90%～30%对比曲线。
容量循环寿命对比表
从上述试验结果可以说明，采用本发明制作的铅碳电池，能够将60%DOD循环次数提高至少3000次以上。
