在锂电材料这条看似传统的赛道上，德福科技却是一家"越老越新"的企业。 它诞生于1985年，是国内最早进入铜箔制造领域的企业之一；但在2017年，又以"新势 力"的姿态切入锂电铜箔赛道，在竞争激烈的市场中逆势崛起。 短短几年，从10微米到6微米再到高强度极薄铜箔，德福科技实现了跨越式突破，一举成长 为全球锂电铜箔产能和出货量最大的企业。 其背后，是对 材料本质的深刻理解和"化学家思维"的长期坚持 。德福科技总裁罗佳博士回 顾，这场转型的起点并非"盲目追薄"，而是基于对电芯设计趋势的前瞻判断。 真正的 竞 争，不是厚度之争，而是性能与体系之争。 正是这种深耕材料机理的执着，使德福科技在高强度、高延伸率、低能耗生产等领域建立了 领先优势；同时，通过柔性产线和全球化布局，构建出覆盖锂电与AI电子电路两大新兴产业 的协同体系。 在行业经历从高速扩张到结构性过剩的周期波动中，德福选择以务实应对，以长期主义稳健 前行。 高工锂电 我们德福科技其实在铜箔领域是一个老兵，我们 1985 年的时候就开始在这个行业去做，但 是某种意义上我们在锂电铜箔领域我们是一个后来者，我们是 16、17 年开始去转型往锂电 铜箔领域去发展，但其 ...
