“…Wang et al mixed 4 m ZnCl 2 with XG to prepare a low‐temperature hydrogel electrolyte that could work at temperatures down to −40°C. It was found that too high a concentration of the ZnCl 2 solution led to loss of viscosity and elasticity of the mixture, while the Young's Modulus and the tensile strength of the hydrogel electrolyte increased as the gum content increased 107 . Zhu et al elaborated the mechanism behind the effect of concentrated salt on both the freezing point and mechanical properties of hydrogel electrolytes 104 .…”

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.

In recent years, the growing demand for increasingly advanced wearable electronic gadgets has been commonly observed. Modern society is constantly expecting a noticeable development in terms of smart functions, long-term stability, and long-time outdoor operation of portable devices. Excellent flexibility, lightweight nature, and environmental friendliness are no less important aspects of the choice of mobile electronics. Naturally, electronic devices need efficient portable power sources (batteries and supercapacitors) that meet the above-mentioned requirements. 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. We would like to introduce recent scientific achievements in the application of noncellulosic polysaccharides for flexible electrochemical energy storage devices as constituents in composite materials for both batteries and supercapacitors. In this review, we will summarize the introduction of biopolymers for portable power sources as components to provide sustainable as well as flexible substrates, a scaffold of current collectors, electrode binders, gel electrolyte matrices, separators, or binding scaffolds for whole devices.

Batteries using a water-based electrolyte have the potential to be safer, more durable, less prone to thermal runaways, and less costly than current lithium batteries using an organic solvent. Among the possible aqueous battery options, ammonium-ion batteries (AIBs) are very appealing because the base materials are light, safe, inexpensive, and widely available. This review gives a concise and useful survey of recent progress on emerging AIBs, starting with a brief overview of AIBs, followed by cathode materials, anode materials, electrolytes, and various devices based on ammonium-ion storage. Aside from summarizing the most updated electrodes/electrolytes in AIBs, this review highlights fundamental mechanistic studies in AIBs and state-of-the art applications of ammonium-ion storage. The present work reviews various theoretical efforts and the spectrum studies that have been used to explore ionic transport kinetics, electrolyte structure, solvation behavior of ammonium ions, and the intercalation mechanism in the host structure. Furthermore, diverse applications of ammonium-ion storage apart from aqueous AIBs are discussed, including flexible AIBs, AIBs that can operate across a wide temperature range, ammonium-ion supercapacitors, and battery–supercapacitor hybrid devices. Finally, the review is concluded with perspectives of AIBs, challenges remaining in the field, and possible research directions to address these challenges to boost the performance of AIBs for real-world practical applications.
