Gel electrolyte based high-performance fiber battery

凝胶电解质基高性能纤维电池

Batteries have experienced rapid development due to their outstanding energy storage performance and widespread applications.This progress has driven advancements in electric vehicles,energy storage systems,and portable electronic devices,while also increasing demand for lightweight designs,high energy density,and environmental sustainability[1].However,traditional rigid batteries face significant challenges related to mechanical flexibility,safety,and environmental impact,making them unsuitable for the unique requirements of these emerging applications[2].Consequently,flexible fiber batteries have emerged,leveraging innovations in materials and structural design to offer energy solutions capable of bending,stretching,and adapting to various complex shapes.These batteries hold great potential in applications such as wearable devices[3],flexible electronics[4],smart textiles[5,6],and biomedical devices[7].Traditional lithium-ion batteries are widely used due to their high energy density and long cycle life.
