固态电池作为下一代储能技术，其产业化进程一直备受关注。然而，制备效率低下和界面接触不良两大难题，长期制约着固态电池的商业化发展。

全固态电池采用固态电解质替代了传统锂离子电池中的液态电解质，从根本上解决了电解液泄漏、燃烧等问题，具备更高的安全性和能量密度。

然而，固态电解质的引入也带来了新的技术挑战。美国密歇根大学迪尔伯恩分校的研究人员指出，在固态电池中，“固体与固体之间的接触”难以做到像液态电解质那样充分贴合。

液态电解质可以流动并填充电极材料的所有孔隙，而固态电解质与电极材料之间的固-固界面接触面积有限。

这不仅增加了界面阻抗，而且在循环过程中，由于体积变化和振动等因素，接触界面容易出现裂纹和孔隙，导致电池性能迅速衰减。

孙学良院士团队的专利核心在于将蜂鸟声共振技术应用于全固态电池制备的多个关键环节，包括：固态电解质的破碎、混合、包覆以及隔膜制备。

声共振混合技术代表了一种截然不同的能量输入方式，设备通过施加与系统固有频率匹配的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左右低频声波，使整个混合容器发生共振。容器内的介质（磨球与粉末）在最高达1cfcdc81e728d9da87ff679a2f3e71d9181a67b7542122cc2f1679091c5a880faf6fb5e6087eb1b2dceccbc87ea87ff679a2f3e71d9181a67b7542122cb5ce2fe28308fd9f2a7baf31679091c5a880faf6fb5e6087eb1b2dcf01679091c5a880faf6fb5e6087eb1b2dc7f89cc1a87ff679a2f3e71d9181a67b7542122c81679091c5a880faf6fb5e6087eb1b2dc2c08a87ff679a2f3e71d9181a67b7542122c95d51679091c5a880faf6fb5e6087eb1b2dc5ef1679091c5a880faf6fb5e6087eb1b2dc1679091c5a880faf6fb5e6087eb1b2dce7dff9f9871679091c5a880faf6fb5e6087eb1b2dca87ff679a2f3e71d9181a67b7542122cdacfcdc81e728d9da87ff679a2f3e71d9181a67b7542122cc2f1679091c5a880faf6fb5e6087eb1b2dceccbc87ea87ff679a2f3e71d9181a67b7542122cb5ce2fe28308fd9f2a7baf31679091c5a880faf6fb5e6087eb1b2dcf01679091c5a880faf6fb5e6087eb1b2dc7f89cc1a87ff679a2f3e71d9181a67b7542122c81679091c5a880faf6fb5e6087eb1b2dc2c08a87ff679a2f3e71d9181a67b7542122c95d51679091c5a880faf6fb5e6087eb1b2dc5ef1679091c5a880faf6fb5e6087eb1b2dc1679091c5a880faf6fb5e6087eb1b2dce7dff9f9871679091c5a880faf6fb5e6087eb1b2dca87ff679a2f3e71d9181a67b7542122cdag的加速度下，进行高速、随机且低幅度的运动。

在固态电解质制备过程中，团队首先通过声共振法分别破碎正极电解质（卤化物）和负极电解质（硫化物），获得多个等级粒度的电解质粉体。

与传统球磨工艺耗时数小时相比，声共振法仅需1cfcdc81e728d9da87ff679a2f3e71d9181a67b7542122cc2f1679091c5a880faf6fb5e6087eb1b2dceccbc87ea87ff679a2f3e71d9181a67b7542122cb5ce2fe28308fd9f2a7baf31679091c5a880faf6fb5e6087eb1b2dcf01679091c5a880faf6fb5e6087eb1b2dc7f89cc1a87ff679a2f3e71d9181a67b7542122c81679091c5a880faf6fb5e6087eb1b2dc2c08a87ff679a2f3e71d9181a67b7542122c95d51679091c5a880faf6fb5e6087eb1b2dc5ef1679091c5a880faf6fb5e6087eb1b2dc1679091c5a880faf6fb5e6087eb1b2dce7dff9f9871679091c5a880faf6fb5e6087eb1b2dca87ff679a2f3e71d9181a67b7542122cda-5cfcdc81e728d9da87ff679a2f3e71d9181a67b7542122cc2f1679091c5a880faf6fb5e6087eb1b2dceccbc87ea87ff679a2f3e71d9181a67b7542122cb5ce2fe28308fd9f2a7baf31679091c5a880faf6fb5e6087eb1b2dcf01679091c5a880faf6fb5e6087eb1b2dc7f89cc1a87ff679a2f3e71d9181a67b7542122c81679091c5a880faf6fb5e6087eb1b2dc2c08a87ff679a2f3e71d9181a67b7542122c95d51679091c5a880faf6fb5e6087eb1b2dc5ef1679091c5a880faf6fb5e6087eb1b2dc1679091c5a880faf6fb5e6087eb1b2dce7dff9f9871679091c5a880faf6fb5e6087eb1b2dca87ff679a2f3e71d9181a67b7542122cda分钟即可完成破碎过程，效率提升数倍。

更为重要的是，声共振法能够精确控制粉体粒度分布，通过颗粒级配设计将不同粒度的电解质粉体混合，获得高压实密度的固态电解质层。

声共振技术在电极包覆方面的应用尤为突出。通过调控声共振设备相关参数，团队实现了核壳结构的构筑。

这不仅降低了成本，而且减少了粘结剂对离子传导的阻碍，提高了隔膜的离子电导率。

随后，通过辊压成型制备卤化物/硫化物双层复合隔膜，有效解决了正负极与不同电解质材料的界面兼容性问题。

与现有技术相比，声共振法制备的全固态电池展现出显著性能优势。

这表明该专利技术已不再是实验室层面的探索，而是具备了产业化应用的前景。

然而，声共振技术在全固态电池产业化道路上仍面临诸多挑战，因为技术目前推广时间有限，所以在从实验室级别的毫升容器放大到百升级别的工业设备的序列中，仍需要大量客户给予机会去做更多的技术验证。

此外，针对不同材料体系的物化特性，我们也需要进一步建立完善的声共振工艺参数数据库，以稳定实现最佳处理效果。

可以预见，随着声共振技术的不断成熟和发展，它将在能源存储和转换领域发挥更为重要的作用。

随着声共振技术在材料制备领域的不断深入，全固态电池的产业化进程将大大加速。未来，我们有望看到更多采用声共振技术制备的高性能、低成本的固态电池应用于电动汽车、储能系统等关键领域。

孙学良院士团队的这项专利，或许将成为推动全固态电池从实验室走向产业化的重要转折点。
