The research in high performance flexible lithium ion batteries (FLIBs) thrives with the increasing demand in novel flexible electronics such as wearable devices and implantable medical kits. FLIBs share the same working mechanism with traditional LIBs. Meanwhile, FLIBs need to exhibit flexibility and even bendable and stretchable features.
On the basis of these flexible components, batteries with different structures and shapes have been well designed to meet the various device configurations. Over the past few decades, there has been a significant surge in the popularity of flexible lithium-ion batteries (LIBs) owing to their high energy density and long cycle life.
Flexible batteries are emerging as crucial energy storage devices for the future of flexible applications. These batteries address the need for high energy density and safety requirements in various fields.
Reliable integration technologies are the determinant for the advancement of flexible batteries. Although the breakthroughs have been achieved in fundamental theory and key materials, there is still a need for further advancements in integration technologies.
The materials employed in the construction of flexible lithium-ion batteries (FLIBs) include carbon nanotubes, graphene, carbon fibres, and conductive polymers for electrodes, alongside solid polymer electrolytes (SPEs) and gel polymer electrolytes (GPEs) for the electrolytes.
The future of wearable technology just got a big boost thanks to a team of University of Houston researchers who designed, developed and delivered a successful prototype of a fully stretchable fabric-based lithium-ion battery.
