高比能固态电池
以固态电解质替代液态电解液，协同先进固态体系、界面稳定与锂（合金）负极、力学—电化学耦合调控三线推进，面向更高能量密度与本征安全的下一代电池。
传统有机电解液电池在能量密度与安全性上日益受限。固态电池以固态电解质取代易燃、易挥发电解液，显著提升安全边界，并使锂金属负极（3860 mAh g⁻¹）具备可用性，从而拓展比能量上限。本研究方向长期聚焦高比能固态体系、固态电解质/电极界面稳定与力学—电化学耦合三大科学与工程难题：一是构建以转化反应为核心的先进固态体系（如固态锂-硫/锂-碘/锂-氧），提出“限域溶解”和“四电子转移”等策略以提升可逆性与功率密度；二是通过锂基合金负极（如 Li–Al、Li–Si）、人工界面层与电解质改性，实现低阻抗、长寿命与抗枝晶；三是面向厚电极与低堆压制造场景，利用原位光纤光栅力学传感、元素掺杂与弹性固态电解质协同设计，缓解应力累积与固/固接触失效，构建高导、稳界面、可制造的固态电芯。
方向一 革新性固态电池体系研发
以转化型正极为核心（固态锂-硫、锂-碘、锂-氧），相较传统嵌入/脱出正极（<250 mAh g⁻¹），在比容量与成本上更具潜力。我们提出“限域溶解”策略与“四电子转移”机理框架，配合离子/电子双通道与界面稳化设计，显著提升比能、倍率与循环可逆性。
