在锂电池的复杂构造中，集流体堪称关键一环。它一般是指电池正负极用于附着活性物质的基体金属，其作用不容小觑。一方面，集流体要吸附承载活性物质，如同坚实的地基支撑着高楼大厦;另一方面，作为导体，它承担着汇聚并输出电流的重任，极大地提升电池的充放电效率，确保电能顺畅传输。

而在提升锂电池整体安全水平的征程中，锂电池集流体安全涂层里的勃姆石崭露头角。勃姆石，学名为γ-AlOOH(水合氧化铝)，又称软水铝石。在动力电池领域，勃姆石已在多个方面展现出改善安全性的重要作用。在涂覆隔膜方面，它能在较低涂层厚度的情况下，显著提升隔膜的热稳定性，增强隔膜的力学性能。这就好比给隔膜穿上了一层坚固的铠甲，降低了隔膜热收缩和穿刺的风险，进而提升锂电池的安全性，同时还能改善电池的倍率性能和循环性能。在极片边缘涂覆中，勃姆石能显著增加动力电池的绝缘性能，为电池安全再添一道保障。当应用于锂电池集流体安全涂层时，勃姆石同样发挥着积极作用，进一步提升安全性能，为锂电池的稳定运行保驾护航。

在勃姆石相关产品的研发与供应领域，安徽壹石通材料科技股份有限公司成绩斐然。公司于2006年1月成立，经过多年的砥砺前行，在2021年8月17日成功在上交所科创板上市。其主营产品涵盖新能源锂电池涂覆材料、电子通信功能填充材料、低烟无卤阻燃材料等三大类。在锂电用勃姆石方面，壹石通已连续三年锂电用勃姆石出货量和市场占有率位列全球第一，是宁德时代勃姆石产品的核心供应商。在电子通信功能填充材料方面，公司更是全球少数能够量产low-α射线球形氧化铝的企业，打破了高端芯片封装材料领域的国外垄断局面。

在充电宝领域，虽然壹石通作为上游功能性材料供应商，其产品与下游终端应用难以一一对应，但公司在锂电安全领域的持续投入与创新，犹如为整个锂电产业链安全升级注入了强大动力。随着新能源产业蓬勃发展，对锂电池安全性能的要求日益严苛，壹石通凭借“内外兼修”的策略及相关优质产品，有望在市场中占据更为有利的地位，为行业发展注入源源不断的新活力，推动锂电池安全性能迈向新的高度，助力整个新能源产业稳健前行。
