会议预告 会议时间： 2025年7月8日-9日 会议地点： 中国 成都 邛崃 "在液态与固态之间，有一道制造鸿沟"，利元亨研究院院长杜义贤博士在2025高工固态电池技术 与应用峰会上如是说。 在全固态电池的产业化过程中，"界面问题"被公认为最大的工艺难点。杜义贤将其细分为两类： 其一是 同种材料之间的界面致密度不足 ，电极或电解质内部孔隙率高，导致离子传输受阻；其二 是 不同材料层之间的结合性差 ，如电极与电解质膜贴合不牢，容易在循环中剥离。 不仅有前段材料成膜和复合的界面问题。往后的 中段 ，叠片环节又引发新的结构风险。全固态电 池取消隔膜，材料在高压下易在边缘变形，导致短路。再到 后段 ，全固态电池化成分容的压力需 求激增，需施加10-30MPa压力，液态电池仅需0.1-1MPa。 第十八届高工锂电产业峰会 ——产业链格局重整 全场景应用共振 2025高工新能源新材料产业大会 —— 新材料·新动能·新生态 主办单位： 高工锂电、高工储能、高工产业研究院（GGII） 总冠名： 英联复合集流体 利元亨基于对全固态电池工艺的研究， 明确了四大关键工艺节点：高压致密化、电解质与电极片 的复合、极片封装与绝缘、高压 ...
