“…The binders are usually polyvinylidene fluoride or poly(tetrafluoroethylene), among which the former is more commonly used. CCs are the most common current collectors for the flexible cathodes prepared with binders, 40,[54][55][56][57]61,[70][71][72][73] and some other flexible substrates are also reported, such as carbon papers, 65,66 stainless-steel films, 33 and graphene oxide (GO)-CNT hybrid films. 74 Ma et al prepared a binder-contained cathode with CC for flexible aqueous zinc-iodine batteries.…”

Flexible aqueous batteries have been thriving with the growing demand for wearable and portable electrical devices. In particular, flexible aqueous multivalent ion batteries (FAMIBs), the charge carriers of which include Zn 2+ , Al 3+ , Mg 2+ , and Ca 2+ , have great potential for development owing to their high safety, high elemental abundance in the Earth's crust, and a multielectron redox mechanism with a high theoretical specific capacity. Therefore, for a comprehensive understanding of this developing field, it is necessary to summarize the recent research progress of FAMIBs in a timely manner.Herein, the advancements of the state-of-the-art FAMIBs are reviewed, and the prospects toward this field are also proposed. This study focuses on the rational material and configuration design for FAMIBs in recent studies to achieve high battery performances under deformation conditions, which is elaborated on by classification of the anode, cathode, hydrogel electrolyte, and configurations of FAMIBs. Besides, the electrochemical performance of FAMIBs under flexible conditions is also reviewed from the perspective of their working voltage, specific capacity, and cycling stability. Finally, the approaches to improve the performance of FAMIBs are comprehensively evaluated, followed by the outlook on the challenges and opportunities in future development of FAMIBs.

“…With the rapid increase of energy demand and aggravation of environmental pollution, much attention has been paid to the development of new energy conversion and storage devices. Zn‐based electrochemical energy storage systems (ZEESSs) using neutral/mildly acidic electrolytes, such as zinc‐ion batteries and zinc‐ion hybrid supercapacitors, have recently aroused unusual research activities 1–3 . This is because the metallic Zn anode has unique advantages of intrinsic safety, low cost, abundant natural reserves, environmental benignity, high‐gravimetric capacity (820 mAh g −1 ), and low‐reduction potential (−0.76 V vs. standard hydrogen electrode) compared to other energy storage systems with organic electrolytes, such as lithium‐ion and sodium‐ion batteries 4–6 .…”

Zn metals have gained the immense attention of researchers for their wide employment as the anode of high-performance aqueous batteries. Nonetheless, the Zn anodes suffer from uncontrollable dendrite growth and parasitic side reactions, which substantially shorten the battery lifespan. This study proposes an interfacial assembly of a metal-polyphenol coordination coating on Zn anodes to regulate Zn 2+ deposition behavior. Bismush-coordinated polyphenolic ligands (i.e., tannic acid, TA) create a functional interface that could promote Zn's uniform nucleation and plating/striping kinetics. Moreover, the artificial coating acts as a physical barrier to inhibit surface corrosion. As a consequence, the TA-Bi-modified Zn anodes display a small voltage hysteresis of ~38 mV at 1 mA cm À2 over 2600 h and an ultra-long lifespan for 3100 h (~4.3 months) even at a high-current density of 10 mA cm À2 . When assembled with a vanadium-based cathode, the full Zn-ion batteries achieve improved electrochemical performance.

“…Preparing composite electrodes via surface modification or doping treatment of CNTs with various pseudocapacitance materials has been confirmed as an effective approach to obtain a capacitor with better overall performance. The pseudocapacitance materials such as metal oxides, [22][23][24][25][26] metal sulfides, [27][28][29][30] and conductive polymers, [31][32][33][34][35] have been used for compounding or doping with CNTs to significantly improve the electrochemical performance of the capacitors. Pseudocapacitors store energy through the reversible faradaic reaction of the electrodes.…”

The continuously reinforced carbon nanotube woven film (CNWF) prepared via the floating catalytic chemical vapor deposition (FCCVD) was modified by mixed acid and vinyltrimethoxysilane (VTMS) respectively to obtain carbon nanotube woven film (CNWF@VTMS) grafted with CH 2 CH group. A series of novel self-supporting composite electrode materials (CNWF@VTMS/PANI) for supercapacitors were then prepared by in-situ chemical oxidative polymerization of aniline in the presence of the CNWF@VTMS film substrate as a conductive network framework. The results showed that CNWF@VTMS/PANI 14 flexible electrode with grape-clustered structure exhibited the highest specific capacitance of 531.3 F/g and the highest energy density of 26.5 Wh/kg at the current density of 1 A/g. It could maintain 75.1% of the initial value at a high current density of 10 A/g. The excellent electrochemical cycle and the structural stability have been confirmed on the condition of the higher capacitance retention of 96.6% after 2000 times of galvanostatic charge/discharge, and the almost unchanged electrochemical performances after 300 times of bending and twisting. Meanwhile, the stronger interfacial bonding between CNWF and PANI endowed a higher tensile strength of 129.2 MPa.
