“…This provides certain viability for solar energy storage applications of PPE. As an illustration, phase change materials used in flexible wearable devices must have high enthalpies and higher photothermal efficiencies so that they can thermally convert in sunlight for a limited duration and provide heat to the body or thermal therapies at the right temperature and for the right duration. − …”

In recognition of their excellent capacity for regulating thermal energy storage and release, phase change materials (PCMs) have been rediscovered and received growing significance in advanced solar energy storage and battery thermal management (BTM). Nevertheless, their insufficient thermal conductivity, poor shape stabilization, and high rigidity hinder their application in BTM systems. Herein, we reported a novel stable ordinary temperature flexible phase change material (FPCM) basis of paraffin wax (PW), polyolefin elastomer (POE), and expanded graphite (EG), which efficiently solves the aforementioned problem. And then, through flexibility, the FPCM was smartly mounted on the power batteries by overfilling, making the components compact and efficient. Thermal contact resistance (TCR) while operating the battery pack could be decreased by the flexible wrapping of the FPCM. Results show that the above BTM assembly effectively reduced the TCR to 0.28 °C/W. This FPCM-based reactive cooling BTM ensures that the temperature of the battery pack is kept under a safe temperature (55 °C) at all times. With the effect of EG, the prepared FPCM exhibits a substantial improvement in thermal conductivity, achieving 1.929 W/mK, as well as a prominent photothermal efficiency of conversion (91.2%). Notably, its ultraflexibility, high thermal conductivity, and excellent latent heat provide a convenient way for the thermal management packaging of complex and multimodel electronic devices.

“…81,82 Combining MOST molecules with fabrics can be an effective strategy to tune the thermal performance of wearable fabrics, 70,83 though these MOST/fabric composites often suffer limitations such as UV-dependent energy storage. Li and co-workers 84 developed a flexible wearable fabric consisting of azobenzene-containing dendrimers 39 (Fig. 15), polydopamine (PDA), and cotton fabric, that can efficiently store UV, green, and red light, thereby having a good match with the solar spectrum, whilst also enabling applications in low- or room-temperature solvent-free environments.…”

“…[4,5] STFs can capture, convert, and store solar irradiation energy and release the stored energy as heat on demand. [6][7][8][9] Currently, a major part of the attention is focused on the design and engineering of photoactive molecules that can undergo reversible photoinduced isomerization upon light irradiation as the process of "charge" and "discharge" of energy. [3,10] However, these molecular STFs still face challenges when it comes to practical applications.…”

Solar thermal fuels (STFs) have been particularly concerned as sustainable future energy due to their impressive ability to store solar energy in chemical bonds and controllably release thermal energy. However, currently studied STFs mainly focus on molecule‐based materials with high photochemical activity, toxicity, and compromised features, which greatly restricts their applications in practical scenarios of solar energy utilization. Herein, we present a novel erythritol‐based composite phase change material (PCM) as a new type of STFs with an outstanding capability to store solar energy as latent heat in its stable supercooling state and release thermal energy as needed. This composite PCM with stored thermal energy can be maintained stably at room temperature and subsequently release latent heat as high as 224.9 J/g during the crystallization process triggered by thermal stimuli. Remarkably, solar energy can be converted into latent heat stored in the composite PCM over months. Through mechanical stimulations, the released latent heat can increase the temperature of the composite up to 91 °C. This work presents a new concept of using spatiotemporal storage and release of latent heat in PCMs for solar energy utilization, making it a potential candidate as STFs for developing future clean energy techniques.
