Designing advanced Zn-ion batteries towards practical applications

由于水基电解液和丰富的锌储量，水基锌离子电池(ZIB)比目前的锂离子电池更安全、更便宜。然而，目前最先进的ZIB技术由于其阴极容量低和锌阳极可逆性差，在实际应用中面临着巨大的挑战。本项目旨在设计具有新型机构和高度可逆的锌阳极的新型阴极。相应地，还将开发按需大尺寸ZIB和工业参数下的柔性器件。该项目的成功将使澳大利亚在大规模智能电网系统、家庭市场和可穿戴医疗设备中实施安全和低成本电池方面处于领先地位。

Aqueous Zn-ion batteries (ZIBs) are much safer and cheaper than current Li-ion batteries due to the water-based electrolyte and abundant Zn reserves. However, the state-of-the-art ZIB technique faces huge challenges for practical applications due to the low cathode capacity and poor Zn anode reversibility. This project aims to design novel cathodes with a new-type mechanism and highly reversible Zn anodes. Accordingly, on-demand large-size ZIBs and flexible devices under industrial parameters will also be developed. The success of this project will place Australia at the forefront of implementing safe and low-cost batteries in largescale smart grid systems, household markets, and wearable medical devices.
