“…Polyaniline (PANI), probably the most studied conducting polymer, is a promising cathode material for aqueous zinc batteries, 1–7 mainly due to its good electrical conductivity, high electrochemical reactivity/reversibility, and low cost. 8–22 Depending on the oxidation degree, three forms of PANI have been recognized: reduction state (leucoemeraldine), half oxidation state (emeraldine), and oxidation state (pernigraniline) (Scheme 1). 23 The redox transitions of leucoemeraldine/emeraldine and emeraldine/pernigraniline result in the two typical redox couples of PANI during electrochemical applications.…”

“…The FTIR and XPS results both provide direct evidence that Cl − and Ga 3+ participated as counterions in the redox reactions during the charging and discharging processes of the GaInSn–PANI battery, as in the case of previously studied Zn–PANI batteries. [ 24 ] The cation–anion hybrid mechanism of PANI cathodes has been proposed in previously reported PANI‐based batteries with promising performances. [ 22 ] In addition, the PANI cathode in the GaIn–PANI battery exhibited the same working mechanism (see the XPS profiles in Figure S16, Supporting Information).…”

A shape-variable aqueous secondary battery operating at low temperature is developed using Ga 68 In 22 Sn 10 (wt%) as a liquid metal anode and a conductive polymer (polyaniline (PANI)) cathode. In the GaInSn alloy anode, Ga is the active component, while Sn and In increase the acid resistance and decrease the eutectic point to -19 °C. This enables the use of strongly acidic aqueous electrolytes (here, pH 0.9), thereby improving the activity and stability of the PANI cathode. Consequently, the battery exhibits excellent electrochemical performance and mechanical stability. The GaInSn-PANI battery operates via a hybrid mechanism of Ga 3+ stripping/plating and Cl − insertion/extraction and delivers a high reversible capacity of over 223.9 mAh g −1 and an 80.3% retention rate at 0.2 A g −1 after 500 cycles, as well as outstanding power and energy densities of 4300 mW g −1 and 98.7 mWh g −1 , respectively. Because of the liquid anode, the battery without packaging can be deformed with a small force of several millinewtons without any capacity loss. Moreover, at approximately −5 °C, the battery delivers a capacity of 67.8 mAh g −1 at 0.2 A g −1 with 100% elasticity. Thus, the battery is promising as a deformable energy device at low temperatures and in demanding environments.

“…The development of fiber-shaped flexible batteries has also been progressing with the increasing demand for wearable electric devices and smart clothing. Fiber-shaped batteries are fabricated by flexible fibrous electrodes, for which the current collectors could be CNT fibers, [127][128][129] and carbon fibers, 119,[130][131][132] graphite layer-coated cellulose yarns, 133 conductive polymer fibers, 130 and stainless steel. 134 Some metal wires 127,135,136 were also directly adopted as free-standing electrodes owing to their intrinsic flexibility and high conductivity.…”

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.
