Electrochromism refers to the phenomenon where materials undergo reversible changes in optical properties under an applied electric field.Electrochromic devices based on this technology have broad application prospects in fields such as smart windows and energy-saving displays,which can contribute to achieving China's"dual carbon"strategic goals(carbon peaking and carbon neutrality).Tungsten bronze nanomaterials are a highly promising electrochromic material due to their abundant raw materials,open framework structure,rich ion transport pathways,and diverse crystal structures.Electrochromic devices prepared from this material feature high contrast ratio,broad spectral modulation range,fast response time,and excellent cycling stability,demonstrating significant potential in smart windows and building energy conservation.This paper reviews the structural characteristics and preparation/synthesis processes of tungsten bronze nanomaterials,summarizes recent domestic and international research progress in the field of electrochromism using tungsten bronze nanomaterials,and provides an outlook on their future development directions and application prospects.
