Research Content
The laboratory focuses on the core issues of key material design and interface regulation of high-capacity solid-state battery system, and focuses on the following research:
1) rational design and multi-scale structure regulation of solid-state electrolyte and electrode materials;
2) interface construction and device integration technology of high-energy-density solid-state batteries;
3) development of special solid-state power supply systems under extreme working conditions.
Based on the theories of condensed matter physics and solid state ionics, we will reveal the lattice dynamics of solid state electrolyte and the ion transport constitutive relationship, and elucidate the electrode/electrolyte interface space charge layer evolution and electrochemical-mechanical coupling mechanism. By integrating material genetic engineering, surface-interface characterization technology and multi-physics simulation, a multi-dimensional correlation model of material intrinsic properties, interface behavior and device performance will be established. Through the development of key technologies such as high-throughput solid-state electrolyte synthesis, high-capacity electrode material design, interfacial functional layer construction, and stress-matched encapsulation, we will develop safe, high specific energy >400 Wh/kg solid-state battery prototype devices, and high-temperature and shock-resistant special battery systems, so that we can provide high-security energy storage solutions for new energy equipment and special application scenarios.
