In this review, we focus on pioneering works of flexible aqueous energy storage devices for flexible electronics, covering the material designs for essential components of the energy devices such as active materials, current collectors, aqueous electrolyte, and separator membranes.
Flexible energy storage devices typically consist of an electrode, electrolyte, separator membrane, and packaging material. To develop this energy device, each component plays its original functions under various deformation states without any flaws.
However, the existing types of flexible energy storage devices encounter challenges in effectively integrating mechanical and electrochemical performances.
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.
Thus, the design of mechanically stable electrolytes and wide electrochemical windows are key factors to utilize flexible aqueous energy storage devices with high energy density .
However, it still has challenges such as the leakage of the liquid electrolyte and the narrow electrochemical window of water molecules (~1.23 V), which poses a formidable obstacle to achieving flexible energy devices for use in practical applications [79, 80].
