“…Aqueous-based Li-ion batteries' excellent reliability and safety features made them appealing for aircraft and submarine uses, which also received attention from the EV engineers to develop them for commercial applications ( Ryu et al., 2020 ). The capacity, energy density, and cycle life of the aqueous Li-ion battery with Li 2 SO 4 electrolyte are found to be 100 Ah/kg, 30 Wh/kg, and 1,000 cycles, respectively ( Song et al., 2020 ; Gu et al., 2019 ). Unlike the low specific energy of the aqueous-based battery, the theoretical specific energy of the Li-ion air (Li-O 2 ) battery was up to two to three kWh/kg ( Black et al., 2012 ).…”

Summary Vehicle electrification has always been a hot topic and gradually become a major role in the automobile manufacturing industry over the last two decades. This paper presented comprehensive discussions and insightful evaluations of both conventional electric vehicle (EV) batteries (such as lead-acid, nickel-based, lithium-ion batteries, etc.) and the state-of-the-art battery technologies (such as all-solid-state, silicon-based, lithium-sulphur, metal-air batteries, etc.). Battery major component materials, operating characteristics, theoretical models, manufacturing processes, and end-of-life management were thoroughly reviewed. Different from other reviews focusing on theoretical studies, this review emphasized the key aspects of battery technologies, commercial applications, and lifecycle management. Useful battery managing technologies such as health prediction, charging and discharging, as well as thermal runaway prevention were thoroughly discussed. Two novel hexagon radar charts of all-round evaluations of most reigning and potential EV battery technologies were created to predict the development trend of the EV battery technologies. It showed that lithium-ion batteries (3.9 points) would be still the dominant product for the current commercial EV power battery market in a short term. However, some cutting-edge technologies such as an all-solid-state battery (3.55 points) and silicon-based battery (3.3 points) are highly likely to be the next-generation EV onboard batteries with both higher specific power and better safety performance.

have also greatly aroused the positive exploration of alternative LIB technologies in recent years. [44] In contrast to the flammable organic electrolyte in LIBs, the aqueous one exhibits lower cost, higher safety, and especially the superior ionic conductivity, which is generally two orders of magnitude higher than that of the organic system. [9,10] All those unparalleled advantages would make the aqueous battery technologies to be the promising candidates in the future. [11] Rechargeable aqueous zinc-ion batteries (AZIBs), which is mainly composed of zinc metal anode, zinc salt-based aqueous electrolyte, and Zn 2+ host cathode, hold the great promise for energy storage applications in very recent years. [12,13] Compared with nonaqueous alkali-ion batteries, the use of cheap and high ambient stable zinc metal anode and inexpensive aqueous electrolyte with superior ionic conductivity (Figure 1a) would make such type of battery to be one of the most promising commercial candidates in the future market. [14-17] To date, extensive studies have been reported for AZIBs, and relating publications have dramatically increased especially in these two years, as shown in Figure 1b. However, the insufficient energy density seems to become the bottleneck that hinder their practical applications at current status. [4,5,18] Such issue could be ascribed to the narrow operating voltage of aqueous electrolyte, insufficient electrochemical performance of cathode materials, and Zn anode. [13,19,20] Besides, the influence of other components such as separator and collector also should be considered to some extent. [20,21] Among them, the studies of widening operating voltage of electrolyte and the optimization of other components only received less attention, which still remain at the early stage. [22,23] On the contrary, more attentions were paid to the electrochemical performance tuning of electrode materials. [24-26] Besides, considering the fixed operating voltage of Zn metal anode, the modification of cathode materials seems to provide more possibilities to effectively improve the energy density of AZIBs, owing to their rich material systems. [20,26,27] Under these considerations, the rational design of advanced cathodes is expected to be a preferential task to develop. Up to now, many types of materials have been exploited as cathode candidates and applied for AZIBs, however, those Rechargeable aqueous zinc-ion batteries (AZIBs) have attracted extensive attention and are considered to be promising energy storage devices, owing to their low cost, eco-friendliness, and high security. However, insufficient energy density has become the bottleneck for practical applications, which is greatly influenced by their cathodes and makes the exploration of high-performance cathodes still a great challenge. This review underscores the recent advances in the rational design of advanced cathodes for AZIBs. The review starts with a brief summary and evaluation of cathode material systems, as well as the introduction of proposed storage mechani...

“…With the increasing demand for wearable and portable electric devices, such as wearable healthcare monitoring systems, smart clothes, and roll‐up displays, flexible batteries that power these devices are urgently needed and thus have been receiving increasing attention in recent years 1–3 . Among flexible batteries, flexible aqueous batteries are most widely studied due to their high safety, eco‐friendliness, and high ionic conductivity of aqueous electrolytes 4,5 . In particular, flexible aqueous multivalent ion batteries (FAMIBs), of which the charge carriers of FAMIBs mainly include Zn 2+ , Al 3+ , Mg 2+ , and Ca 2+ , have great potential for development because of the multi‐electron redox of the multivalent ions, which endows the FAMIBs with high theoretical energy density compared with alkali metal ion‐based batteries 6–8 .…”

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.
