Advanced zinc-ion batteries with high voltage and high energy density

锌离子电池不仅比目前的锂离子电池（LIB）便宜，而且由于中性水电解质，它更安全。然而，与更主流的锂离子电池相比，其电网规模的发展受到有限的输出电压和能量密度不足的困扰。本项目旨在通过制备原子级结构的锰基工程阴极和新型稳定的固态电解质来解决放电电压问题，并通过锌阳极界面纳米技术来提高器件的能量密度。该项目的成功将有利于澳大利亚进入新市场，并为澳大利亚丰富的锌和锰资源的长期可行性引入一种新的低成本和安全的储能技术。

Zinc-ion battery is not only cheaper than current lithium-ion battery (LIB), but it is safer due to a neutral aqueous electrolyte. However, its grid-scale development is plagued by limited output voltage and inadequate energy density compared with more mainstream LIB. This project aims to solve the discharge-voltage problem by fabricating atomic-level structure engineered manganese (Mn)-based cathode and a new stable solid-state electrolyte, and improve the device energy density by zinc (Zn) anode interface nanotechnology. The success of this project will benefit Australia’s access to new markets and introduce a new low-cost and safe energy storage technology for the long-term viability of Australia’s abundant Zn and Mn resources.
