Innovation and Challenges in Materials Design for Flexible Rechargeable Batteries: from 1D to 3D


Due to the emergence of numerous flexible electronic devices, Design and fabrication of flexible power sources with high energy density have attracted great attention in the field. Among various energy storage technologies, flexible rechargeable batteries are the most promising, because of their unique features including high flexibility, high specific energy density, light weight properties, etc. To achieve this concept, the flexibility of each component is considered a key property in addition to required electrochemical capabilities. In this review, recent advances amongst different kinds of flexible rechargeable batteries are discussed, including lithium-ion batteries (LIBs), lithium-sulfur (Li-S) batteries, lithium-air (Li-air) batteries, zinc-air batteries (ZABs), and sodium-ion batteries (SIBs). Based on the macro-shapes and micro-structures, flexible batteries can be divided into three types: one-, two-, and three-dimensional. Further, sub-classification is performed within each type according to their material composition such as carbon-based, polymer-based, inorganic materials-based, hybrid materials-based etc. It is important to note that the design for flexibility is also influenced by the manufacturing process. Thus, this review focuses not only on the selection and preparation of component materials, but also on the complete battery assembly process. Since some experimental data for flexible batteries is still limited by today’s technology, a performance simulation has also been included to predict and describe the battery performance. Finally, key challenges and perspectives for the advanced flexible battery technologies are outlined to provide guidance for future research work.
