the developing trend of modern electronic technologies, [6] and significant efforts have been devoted to transforming these energy storage systems to their light, flexible, small, and thin counterparts. [7] The flexible battery market is forecast to increase rapidly from $69.6 million in 2015 to $958.4 million in 2022. [8] Lithium-ion batteries (LIBs) historically and presently dominant the markets of rechargeablebattery for portable devices because of the lightness of lithium and high energy density of the battery systems. [9,10] Nonetheless, LIBs are marred by the high cost and the shortage of lithium resources. Moreover, the aprotic electrolytes used in LIBs are generally toxic and flammable. This fact causes great safety issues for LIBs, especially when they are used in wearable/implantable applications in close contact with human body. It is highly challenging to assemble flexible LIBs due to the requirement of a highly reliable protective packaging to avoid the electrolyte leakage and reconcile with the washing need of wearable devices in practical applications. [3] Moreover, due to the high barrier encapsulation, the volumetric performance would be severely restricted, especially when LIBs are miniaturized. In this context, it is highly desirable to prepare flexible "beyond Li-based" batteries with safe, low-cost, and eco-friendly aqueous electrolytes. [11] As alternatives for LIBs, multivalent ion battery technologies (Zn-ion battery, ZIB, Mg-ion battery, and Al-ion battery) are of high interest for electrochemical energy storage. In comparison with LIBs operating with single-electron transfer, multivalent ion batteries employ multielectron transfer during the charge/ discharge processes, thus delivering much higher volumetric energy densities. [12][13][14] Since the first utilization of Zn in batteries in 1799, [15] Zn metal has captured increasing attention as an ideal anode material. In earlier studies, Zn anodes were widely explored in many alkaline battery systems, such as alkaline zinc-MnO 2 batteries, [16] zinc-nickel batteries, [17][18][19][20] zinc-silver batteries, [21] and zinc-air batteries. [22][23][24] Zn metal is able to offering both high gravimetric and high volumetric capacities (820 and 5855 mAh cm −3 ). [25] Moreover, Zn has the merits of low cost, low-toxicity, abundance in earth crust (≈300 times higher than for lithium), environmental benignity, easily recyclable, and intrinsic safety. [14,26] These advantages directly drove the recent renaissance of Zn anode based batteries. [15] However, the use of corrosive alkaline electrolyte leads to the Zn-dendritic (sharp, needle-like metallic protrusions) growth [27,28] and soluble ZnO 2 2− formation on Zn anode, which poison the cathode and result in the rapid capacity To keep pace with the increasing pursuit of portable and wearable electronics, it is urgent to develop advanced flexible power supplies. In this context, Zn-ion batteries (ZIBs) have garnered increasing attention as favorable energy storage devices for flexible electronics, ...

“…Another limitation is that this morphing composite material is not yet operable in an ambient environment due to the inserted Li and presence of solvents, but this can be remedied by a suitable outer barrier such as layers of ultrathin glass (31).…”

Structures that are capable of changing shape can increase efficiency in many applications, but are often heavy and maintenance intensive. To reduce the mass and mechanical complexity solid-state morphing materials are desirable but are typically nonstructural and problematic to control. Here we present an electrically controlled solid-state morphing composite material that is lightweight and has a stiffness higher than aluminum. It is capable of producing large deformations and holding them with no additional power, albeit at low rates. The material is manufactured from commercial carbon fibers and a structural battery electrolyte, and uses lithium-ion insertion to produce shape changes at low voltages. A proof-of-concept material in a cantilever setup is used to show morphing, and analytical modeling shows good correlation with experimental observations. The concept presented shows considerable promise and paves the way for stiff, solid-state morphing materials.

“…By releasing the strain, SSBs can well adapt to the strain state in the process of mechanical deformation. And compared with the liquid electrolytes, the stability of the electrode–electrolyte interface can also be greatly improved . Hence, all‐solid‐state thin‐film batteries with ultrathin electrodes are emerging in recent years.…”

In order to meet the growing demands of electric vehicles and portable devices, the electrochemical performance of rechargeable batteries is required to be further optimized. Above all, it is of vital importance to understand the reaction mechanism of batteries under working states, which requires a direct observation of the complicated reaction process. Thus, in situ X‐ray diffraction (XRD) techniques have been employed in the charge and discharge process to realize real‐time monitoring and provide on‐site information of structural evolutions and phase transitions within electrode materials. In this review, a detailed summary of lab‐scale in situ X‐ray diffraction techniques is given and compared with in situ synchrotron XRD at the same time. First, four typical in situ reaction mechanisms are presented and their distinctive characteristics are introduced in detail. Second, the practical applications of in situ X‐ray diffraction in different battery systems are described with examples after extensive collections. In addition, the design of in situ cells and some noteworthy experimental details in actual testing are also mentioned. Finally, the further development direction of in situ X‐ray diffraction techniques is well prospected.
