Smart energy storage has revolutionized portable electronics and electrical vehicles. The current smart energy storage devices have penetrated into flexible electronic markets at an unprecedented rate. Flexible batteries are key power sources to enable vast flexible devices, which put forward additional requirements, such as bendable, twistable, stretchable, and ultrathin, to adapt mechanical deformation under the working conditions. This review summarizes the recent advances in construction and configuration of flexible batteries and discusses the general metrics to benchmark various flexible batteries with different materials and chemistries. Moreover, we present advanced prototype flexible batteries developed by some companies to afford general envision of the technological status. Lastly, the critical points are summarized in the development of flexible batteries and remaining challenges are also presented for the future design of flexible batteries in practical perspectives.

“…Several recent review papers are available which contain excellent discussions on the state of knowledge of sodium layered oxide cathodes and shed light on the development of these materials. [ 32–37 ] Among the different possible structures of the Na x MO 2 compounds, the most interesting from an electrochemical point of view are P2‐ and O3‐phases, which differ from each other by the different stacking sequence of the sodium ions and the transition metal layer ( Figure 5 ).…”

“…In fact, one of the main intrinsic drawbacks of sodium layered oxides is due to these phase transitions that cause large volume changes in the material (≈23%) and lead to poor capacity retention and cycling performance. [ 37 ] This structural instability is specially critical in Mn‐based sodium layered oxides, where the presence of Mn 3+ cations causes a distortion in the structure due to the Jahn Teller effect leading to degradation on cycling. By doping/substitution with different elements, it is possible to stabilize the structure limiting the amount of Mn 3+ ions.…”

“…[ 49–52 ] The O3‐type phases, due to the higher sodium content, provide higher capacities, such as the O3‐NaNi 0.5 Mn 0.5 O 2 phase that can deliver ≈105 and 125 mAh g −1 at rates of 24 and 4.8 mA g −1 , respectively, in the voltage range of 2.2–3.8 V. [ 53 ] The presence of other co‐dopant elements in the appropriate amounts such as Fe, Co, or Ti can improve long‐term cycling ability in addition to excellent specific energy density. [ 37 ] A clear proof of the positive synergistic effect of the introduction of co‐dopants is the Na a Ni (1‐ x ‐ y ‐ z ) Mn x Mg y Ti z O 2 material, selected by Faradion Limited as cathode in its prototype of commercial NIB. [ 54 ] Small amounts of doping can influence the structure evolution of the materials upon cycling, improving electrochemistry.…”

are proving to be an emergent technology with potentially very attractive properties. They are potentially low cost and environmentally friendly with reduced supply risk. However, the development of NIBs faces various challenges such as low gravimetric and volumetric energy densities and difficulty in achieving broader voltage windows. Although early studies in NIBs date back to the 1970s, just like Li-ion battery (LIB) research, the commercialization of the former systems in 1991 by the team formed by Sony and Asahi Kasei marked a milestone not only in the field of energy storage technology but also in the evolution of the modern society. This technological breakthrough had been possible thanks to several preceding contributions, particularly the works by M. S Whittingham, [1] J. Goodenough, [2,3] and A. Yoshino [4] on the discovery of Li-ion intercalation materials (Nobel Laureates in Chemistry 2019). This important historical event polarized material science research toward Li-ion technology and slowed down considerably the advances in the field of sodium. However, at the end of the 2000s, mainly driven by the concerns about future lithium supply and the uneven worldwide distribution of its reserves and resources, the research on Na-ion reemerged and so did the number of articles published (Figure 1). The intercalation chemistry of both metal ions is very alike, and thus, the materials tested for NIBs could be similar to those used in Li-ion systems. Both systems share the same working principle, and therefore, in terms of manufacturing, the industry producing LIBs can be easily tuned towards NIB fabrication, which is an important asset to invest in and support this technology. NIBs started to reach the market in the early 2010s, about two decades after their Li counterparts. Nevertheless, the progress has been relatively fast due to the straightforward LIB equipment and facility transfer just mentioned. In the search of high performance, low cost, abundance, low environmental impact, long-term cyclability and safety, layered metal oxides, polyanionic compounds and Prussian blue analogues (PBAs) are among the most studied families of Na-ion cathode materials. On the anode side, metallic sodium exhibits the same operation and safety problems as lithium, and therefore, it cannot be considered an option in conventional NIBs. Thus, in this scenario, most of the research has been dominated by the use of disordered carbons, mainly hard carbons (HCs). Other prospective anodes

“…The impressive progress in battery‐type electrode for NIBs has been made in the past 10 years, but there are still plenty of problems to be unsolved for NIMEESDs, for instance, the toxic components or precious transition metals in electrode materials, [ 130 ] the incompatibility between rigid electrode materials and flexible MEESDs, [ 131 ] and large volume expansion of anodes with conversion and alloying processes. [ 132 ] To address the aforementioned issues, it is effective to adjust the intrinsic electrode properties through valance adjustment, phase engineering, and surface modification to extract every bit of performance enhancement possible, [ 114,133 ] for instance, robust structure for periodic reversible sodiation/desodiation process and exceptional electrical conductivity for fast electrochemical response. This is substantiated by nanohoneycomb SnS arrays with ultrathin nanosheets and smaller lateral sizes that deliver superior performance metrics compared with nanoflake and nanowall SnS arrays.…”

With the onset of "intelligent" era marked by flexible and wearable microelectronics, the Internet of Things (IoT), implantable medical devices, smart sensors, and wireless charging, [1-4] conventional electrochemical energy storage devices (EESDs) being bulky and rigid cannot meet the demand of rising microelectronics due to poor integrability. [5-7] In addition, conventional EESDs also have severe problems stemming from intrinsic limitation on architecture, for instance, thick commercial separator (glass fiber) limiting the ion diffusion kinetics, and the safety issue of commercial batteries pertaining to the alkali metals (e.g., Li, Na). [8,9] Naturally, their electrochemical performance is subpar and cannot keep up with the development of shapeless and flexible integrated circuits. [10-13] These issues have intensified the pursuit of flexible, versatile, compatible, and on-chip microscale EESDs (MEESDs) as promising power source, which could be integrated with microrobots, wearable devices, or microelectronics with low power consumption (milliwatts to nanowatts). [14-17] Microsupercapacitors (MSCs) with high power density, fast chargedischarge rate and ultra-long life have exhibited easy integration, and good mechanical flexibility, [18,19] which store charge by fast ion adsorption/desorption or highly reversible redox reactions at the interface between the electrode and electrolyte. [20,21] MSCs can power various electronics from watts to microwatts power (Figure 1), but the energy density of MSCs is insufficient to support the high-energy consumption electronics, such as longrange communication, and cannot provide power supply for a long time (hours). [22,23] By contrast, microbatteries (MBs) with high energy density could be hopeful to satisfy the energy requirements of some mobile devices for long-term consumption from nanowatts to milliwatts, such as 32 KHz quartz oscillator in nanowatts, electronic watch in microwatts, and miniature
