2月28日，以"聚集新技术 探索新工艺"为主题的行业首届圆柱电池技术——2025起点锂电圆柱电池技术论坛暨圆柱电池20强排行榜发布会，在 深圳宝安登喜路国际酒店正式举办，现场超200+圆柱电芯及应用、300+电池材料设备配套企业齐聚盛会，携手共探新发展，共创新机遇。 大圆柱电池行业在中国蓬勃发展，逐渐从引领行业到引领全球的趋势发展。在此背景下，对结构件和原材料的要求越来越严格。 我们主要是做结构件的基材，是预镀镍材料，主要是做电池壳。 我先讲讲预镀镍工艺，从炼钢开始，然后是热轧、酸轧、退火、镀镍等。钢铁行业在中国、在世界是很成熟的技术，这里的参数有好几百项， 在这几百项当中，预镀镍产品只把控本工序指标，我们感觉很不够，所以参考行业的原则，就是"一贯制"，从炼钢炼铁开始就开始把控。最核 心的关键参数有32项，从炼钢的成分控制，到热轧的温度控制，以及退火和镀镍的核心参数。炼钢主要是夹杂物的控制，热轧主要是温度及性 能控制，酸轧主要是厚度均匀性控制，退火主要是综合性能及合金层控制，镀镍主要是镀层控制。 预镀镍的工艺，主要是脱脂清、电解、连续合金化化退火、连续立式镀镍、平整、分条和使用。电镀的清洗，20年前，它的清晰 ...
