Advancing Solid-State Anode-Free Batteries with Lithium and Sodium Solid Electrolytes

Project description

The project aims to develop high-performance anode-free solid-state batteries using lithium and sodium-based solid electrolytes. By eliminating the conventional anode and leveraging solid-state technology, this research seeks to significantly enhance energy density, improve safety, and reduce the overall cost of next-generation batteries. Unlike traditional batteries with pre-deposited metal anodes, these systems rely on the deposition of lithium or sodium metal directly onto the current collector during operation. This approach minimizes excess reactive material, increasing safety and energy density. Solid-state electrolytes, known for their high ionic conductivity and dendrite suppression capabilities, are critical to the success of this technology. The key challenges that has to be addressed in this project includes improving interfacial resistance, uniform plating/stripping, developing stable electrolyte, and enhancing cycle life of the device.

Outcomes

Research Objectives:
1. Development of novel lithium and sodium solid electrolytes using NASICON, garnet and perovskite ceramic materials. Coated current collectors will be developed to mitigate dendrite formation.
2. Interface engineering will be done by introducing interlayers (e.g. polymer coatings, ionic liquids) to reduce resistance and improve compatibility.
3. Characterization of developed solid electrolytes and employment of advanced techniques to study interfacial behaviour of device.
4. Optimisation of electrolyte composition and current collector design to achieve uniform metal deposition.
