“…Another inspiring example of flexible battery design is the spine‐like Li‐ion batteries (Figure 14A), in which a thick, rigid segment mimicking vertebra of animals stores/releases energy, while a thin and flexible interconnection serving as marrow withstand deformable strains (Figure 14B). 101 The “vertebra” electrode can be made thick and massively prepared by slurry coating technique, ensuring high active materials loading. The “marrow” interconnections enable a harsh dynamic mechanical load, endowing batteries with excellent flexibility.…”

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.

“…Based on animal spine structure, Yang et al demonstrated a scalable method to enable flexible lithium batteries with large capacity and good flexibility based on commercially available battery materials, as displayed in Figure 5A. 122 The cutting strips based on anode/separator/cathode/separator stack correspond to hard vertebra units in spine, while soft conductive parts connect hard stack parts together, just like the way of soft marrow. The energy density of batteries is just compromised by connecting parts, and is easy to achieve over 90% of original cells.…”

Lithium‐ion batteries have exerted great influence on our daily life as important power supply. However, lithium‐ion batteries suffer from critical challenges, including dendrite effect and insufficient ion kinetics, which lead to low efficiency and poor cycling. Bio‐inspired structures, directly learned from nature, have some special characteristics with good mechanical properties, including large surface area, numerous active sites, and ion channels. The large surface area can accommodate more ions, and active sites facilitate intermediate conversion. The well‐designed ion channels are beneficial to ion migration, and then greatly promote charge–discharge processes. Here, we summarize typical bio‐inspired structures for lithium‐ion batteries, discuss influence of these structures on battery performance. Based on the theoretical analysis and our experimental experience, we highlight the design requirement of bio‐inspired structures to enable battery devices with high power density and stable cycling life. Finally, perspectives on existing issues in the filed have been made for future directions.

“…Bioinspired, spine-like shape and expandable honeycomb structures can further enable the 3D-shaped EES devices towards being more flexible and stretchable. [30][31] The evolution in the flexibility and shape of the customizable EES devices marked a significant scientific endeavor in the first decade. The marriage of EES devices with bioconformable properties (biodegradable 32 , breathable 33 , washable 34 , aesthetic 35 and biocompatible [36][37] ) presents another significant milestone towards a higher degree of customizability.…”
