Recent progress and perspectives on advanced flexible Zn-based batteries with hydrogel electrolytes
which feature intriguing characteristics of being soft and wet
accompanied with high solubility of zinc salts
are especially advantageous for fabricating flexible Zn-based batteries. Furthermore
the abundant and tunable chemistries of hydrogels offer opportunities to bestow novel affiliated functionalities
such as super toughness
extreme temperature tolerance
stimuli-responsive properties
and self-healing capability
by engineering polymer chains and chemical structures to fabricate flexible batteries with unprecedentedly scintillating functions. Herein
the design principles of functional hydrogel electrolytes including polymer chemistry
synthesis methods
characterisation and versatility demonstration for flexible Zn-based batteries are comprehensively reviewed. Relevant challenges and perspectives are also analysed and discussed.
