“…Such a porous polymeric network can be used to shape‐stabilize phase change materials (PCMs) for thermal energy storage applications. [ 14b ] The chemical cross‐linking of phenol via paraformaldehyde can lead to the formation of polymeric hydrogels with high porosity, a high degree of cross‐linking density, and tunable pore size distribution (Figure 3b). [ 85 ] Such a porous structure can be carbonized through a controlled pyrolysis process to fabricate carbon porous structures.…”

“…To reach high energy storage densities, [ 57,149 ] fast energy storage/release, [ 150 ] high flexibility, [ 151 ] improved electrical/thermal/ion conductivity, [ 14b,152 ] and fast self‐healing properties, [ 153 ] polymer hydrogels can be reinforced with different fillers/additives to fabricate composite polymer hydrogels. The incorporation of additives, such as nanomaterials, not only mostly improves the accessible surface area of polymer hydrogels but also provides a route to control the morphology of the hydrogels to improve the final properties of these porous materials.…”

“…[ 163 ] The PCM leakage through the phase transition is the main obstacle to the wide‐range application of PCM‐based energy storage systems. [ 14b ] Using polymer hydrogels, PCMs can be shape‐stabilized to solve this problem. [ 14b ] Moreover, the low energy storage/release rate of flexible PCMs due to the low thermal conductivity of PCMs can be solved by using conductive polymer hydrogels to improve the performance of wearable energy storage devices based on such technology.…”

The recent and fast‐growing trends related to the development of wearable technologies have raised the need for efficient and high‐performance energy storage devices having extra features such as flexibility and lightweight. Polymer hydrogels, as viscoelastic lightweight porous nanostructures with tunable surface and structural properties, can play a crucial role in the design of these future energy storage devices. Herein, recent developments and progress in the use of polymer hydrogels to design flexible and wearable energy storage devices are presented and discussed. The 3D structure of polymer hydrogels and porous nanostructures based on these hydrogels provides a platform to design flexible supercapacitors, batteries, and personal thermal management devices. Herein, different types of polymer hydrogels are presented, and their main fabrication techniques are reported. Moreover, the main structural properties affecting the energy storage performance of polymer hydrogels are discussed. In addition to recent progress in the design of polymer‐hydrogel‐based wearable devices, recent developments in polymer hydrogels for flexible applications (batteries, supercapacitors, and thermal energy storage systems) are reviewed in detail.
