涂碳铝箔作为改性正极集流体，可降低集流体之间接触电阻，收集活性物质的微电流进而改善电池的倍率充放电性能、循环性能。涂碳 铝箔是通过在光箔表面涂覆一层均匀的导电性材料（如炭黑、石墨片和石墨烯）而制得，对比涂炭铝箔与光箔，涂碳铝箔表面形态更加 均匀。涂碳铝箔表面涂覆层作为桥梁可提升正极片的导电性、降低电池内阻；此外，可提高活性物质与集流体的粘附力，目前主要用于 磷酸铁锂电池。 涂碳铝箔是一种可延长电池组寿命的材料。涂碳铝箔（导电涂层）分水性（水剂体系）和油性（有机溶剂体系）两种类型，能提供静态 导电性能，收集活性物质的微电流，从而可以大幅度降低正 / 负极材料和集流之间的接触电阻，并能提高两者之间的附着能力，可减少 粘结剂的使用量。 导电涂碳铝箔行业目前现状分析 随着近些年锂电迅猛发展，锂电池用集流体发展也很快。正极铝箔由前几年的 16um 降低到 14um ，再到 12um ，现在已经不少电池生产 厂家已经量产使用 10um 的铝箔，甚至用到 8um 。而负极用铜箔，由于本身铜箔柔韧性较好，其厚度由之前 12um 降低到 10um ，再到 8um ，到目前有很大部分电池厂家量产用 6um ，以及部分厂家正在开发 ...
