Flexible batteries have the potential to develop an ideal energy storage system for future electronics due to their advantages in safety, working temperature, high energy density, and packaging. The entire battery architecture must be transformed to design flexible batteries, including active materials, electrolyte, and separators.
The energy density of flexible batteries varies depending on the battery shape and size. For example, the volumetric energy densities of medical patch, watch belt, bendable phone, and roll-up display are in the level of 80, 400, 450, 550, and 700 Wh/L, respectively, as indicated in Figure 5A.
Compared to conventional rigid batteries configurations, the energy density of flexible batteries is significantly reduced due to the inclusion of a substantial amount of electrochemically inactive materials necessary for ensuring the flexibility of the batteries.
Compared with flexible batteries, stretchable batteries need to bear more serious deformations, including stretching and twisting, which require the electrodes for stretchable batteries to possess even better mechanical properties [11, 87].
Flexible batteries (FBs) are the superior choice of energy supply for portable electronics nowadays. Generally used lithium-ion batteries are not flexible due to the low flexibility of their battery components.
Flexible batteries are emerging as a powerful platform due to the rise of IoT, and wearable electronics, which cannot be powered by rigid Li-ion batteries. These flexible applications require the rational design of battery materials, structures, and configurations to adapt their shape-changing conditions.
