What are flexible energy storage devices?
Flexible energy storage devices are innovative systems designed to store energy in a versatile format, facilitating varied applications across
To achieve complete and independent wearable devices, it is vital to develop flexible energy storage devices. New-generation flexible electronic devices require flexible and reliable power sources with high energy density, long cycle life, excellent rate capability, and compatible electrolytes and separators.
However, the existing types of flexible energy storage devices encounter challenges in effectively integrating mechanical and electrochemical performances.
The electrolytes utilized in the flexible aqueous energy storage devices (SCs, ZIBs, and metal–air batteries) are hydrogel electrolytes that possess non-volatile and non-flammable properties. Consequently, there is no risk of fire or explosion resulting from electrolyte leakage or device short-circuiting.
As usual, the mechanical reliability of flexible energy storage devices includes electrical performance retention and deformation endurance. As a flexible electrode, it should possess favorable mechanical strength and large specific capacity. And the electrodes need to preserve efficient ionic and electronic conductivity during cycling.
A typical flexible self-charging system integrates at least two types of devices for energy harvesting and storage on a single substrate and involves three energy conversion steps. Various flexible energy-harvesting technologies can convert ambient energy into electricity.
However, most of these power sources use plastic substrates for their manufacture. Hence, this review is focused on research attempts to shift energy storage materials toward sustainable and flexible components.
