Aqueous zinc ion batteries based on sodium vanadate electrode materials with long lifespan and high energy density

Abstract

With the excessive consumption of non-renewable energy sources and subsequent environmental pollution, research focuses have shifted to the development of emerging energy storage devices with desired performance. Aqueous zinc-ion batteries (AZIBs) are expected to become potential alternatives due to their high safety, low cost and environmental friendliness. In this work, we have prepared Na7V7.6O20·4H2O (NVO) nanobelts by a facile hydrothermal route. NVO/Zn batteries have been assembled with the as-obtained product as cathodes, which deliver a capacity of 309.4 mA h g−1 at 0.3 A g−1. They maintain excellent cycling stability after 10 000 cycles at 10 A g−1.
