Benefiting from the inherent properties of ultralight weight, ultrahigh porosity, ultrahigh specific surface area, adjustable thermal/electrical conductivities, and mechanical flexibility, aerogels are considered ideal supporting alternatives to efficiently encapsulate phase change materials (PCMs) and rationalize phase transformation behaviors. The marriage of versatile aerogels and PCMs is a milestone in pioneering advanced multifunctional composite PCMs. Emerging aerogel-based composite PCMs with high energy storage density are accepted as a cutting-edge thermal energy storage (TES) concept, enabling advanced functionality of PCMs. Considering the lack of a timely and comprehensive review on aerogel-based composite PCMs, herein, we systematically retrospect the state-of-the-art advances of versatile aerogels for high-performance and multifunctional composite PCMs, with particular emphasis on advanced multiple functions, such as acoustic-thermal and solar-thermal-electricity energy conversion strategies, mechanical flexibility, flame retardancy, shape memory, intelligent grippers, and thermal infrared stealth. Emphasis is also given to the versatile roles of different aerogels in composite PCMs and the relationships between their architectures and thermophysical properties. This review also showcases the discovery of an interdisciplinary research field combining aerogels and 3D printing technology, which will contribute to pioneering cutting-edge PCMs. This review aims to arouse wider research interests among interdisciplinary fields and provide insightful guidance for the rational design of advanced multifunctional aerogel-based composite PCMs, thus facilitating the significant breakthroughs in both fundamental research and commercial applications.

Mineral-based form-stable phase change materials for thermal energy storage: A review on encapsulation techniques, performance enhancements and practical applications

Three-Dimensional Interpenetrating Network Phase-Change Composites with High Photothermal Conversion and Rapid Heat Storage and Release

This review paper collects recent and relevant research articles on the topic of heat transfer enhancement in phase change materials heat storage systems, covering both passive techniques as well as active techniques. The heat transfer techniques analyzed and included in the review were critically examined and discussed (1) from the heat transfer enhancement point of view and (2) from the alteration of the heat storage capacity point of view. Heat transfer enhancement techniques system integration and optimization was addressed in the relevant context. The main passive techniques families included in this review were inserts, nanoparticles, heat pipes and packed-bed PCMs. A significant number of research articles was found on the topic of combining two or more techniques. Active techniques for heat transfer enhancement in PCMs are scarce in the literature. The active techniques discussed in this review are electric field, magnetic field and ultrasounds. Research gaps were discussed and future research directions were suggested, such as hybrid passive – active techniques.

LiCoO2 has suffered from poor stability under high voltage as a result of insufficient Co–O bonding that causes lattice oxygen release and lattice distortions. Herein, we fabricated a high-voltage LiCoO2 at 4.6 V by doping with Ni/Mn atoms, which are obtained from spent LiNi0.5Mn0.3Co0.2O2 cathode materials. The as-prepared high-voltage LiCoO2 with Ni/Mn substitutional dopants in the Co layer enhances Co–O bonding that suppresses oxygen release and harmful phase transformation during delithiation, thus stabilizing the layered structure and leading to a superior electrochemical performance at 4.6 V. The pouch cell of modified LiCoO2 exhibits a capacity retention of 85.1% over 100 cycles at 4.5 V (vs graphite). We found that our strategy is applicable for degraded LiCoO2, and the regenerated LiCoO2 using this strategy exhibits excellent capacity retention (84.1%, 100 cycles) at 4.6 V. Our strategy paves the way for the direct conversion of spent batteries into high-energy-density batteries.

Electrochemical performance of in situ LiFePO4 modified by N-doped graphene for Li-ion batteries

Functional modification (functional group modification, nanostructured material modification, acid/alkaline modification, hydrophilic/hydrophobic modification and external condition assisted modification) of porous encapsulation media plays an important role in promoting phase change behavior and improving heat storage characteristics of form-stable composite phase change materials (fs-CPCMs). This review focused on latest experimental advances in functional modification strategies and their influence on the performance of fs-CPCMs. The main factors affecting the phase change behavior of fs-CPCMs included functional group types of modifiers and pore structure characteristics of porous media. The heat storage characteristics were effectively improved by regulating surface properties and pore/structure features of encapsulation media, which was mainly attributed to the weakened interaction between encapsulation media and phase change materials (PCMs), increased encapsulation capacity and improved heat transfer. This work could provide basis and support for the regulation of phase change behavior of fs-CPCMs and the improvement of heat storage performance.

Effect of functional modification of porous medium on phase change behavior and heat storage characteristics of form-stable composite phase change materials: A critical review

The thermal conductivity enhancement fillers usually have significant effect on the crystallization behavior of composite phase change materials (CPCMs), thereby affecting heat release performance. In this work, the non-isothermal crystallization of polyethylene glycol (PEG)-Ag nanowires/expanded vermiculite CPCMs (PAE CPCMs) was studied in detail to clarify the effect of Ag nanowires on crystallization behavior of PAE CPCMs. The results indicated that the Ag nanowires inhibited crystal growth of PEG because PAE CPCMs showed longer half crystallization time, lower crystallization rate and higher value of F(T) than PEG during non-isothermal crystallization, which could quantitatively explain the degradation of heat release performance of PAE CPCMs caused by surfaces interaction of Ag nanowires-induced decline of crystallinity.
