Fabrication of Organic Shape-stabilized Phase Change Material and Its Energy Storage Applications

Abstract: Organic phase change materials (OPCMs) are advanced energy storage materials with ability to storage and release thermal energy at constant temperature. Efficient energy storage systems using shape-stabilized PCMs (SSPCMs) are promising to adjust the gap between energy supply and demand. The performances of SSPCMs are influenced by multiple factors which are necessary to be considered in the fabrication process. In this regard, we summarized the desired properties for OPCMs and SSPCMs, then we systematically d… Show more

“…With increasing environmental concerns and growing global energy demand, developing efficient energy conversion and storage devices is urgently needed. Growing attention has been turned to lithium–sulfur (Li–S) batteries that have superior theoretical capacity (1675 mAh g –1 ) and energy density (2654 wh kg –1 ) over Li-ion batteries. However, Li–S batteries encounter two roadblocks on the way to practical application: sulfur volume change and shuttle effect. Enhancing Li–S battery performance needs to simultaneously buffer sulfur volume fluctuation as well as suppress polysulfide dissolution during cycling. Carbon materials have been widely used due to their sustainability and abundance. Specifically, nanocarbon materials such as carbon nanotubes (CNTs), porous carbons, graphene and metal–organic frameworks (MOFs) have demonstrated encouraging success in jointly addressing challenges in the Li–S battery. Recently, CNTs have been explored as sulfur hosts because of their outstanding mechanical properties (with Young’s modulus of 1.05 ± 0.05 TPa and shear modulus of 0.45 TPa) and tubular microstructures, which were found effective in buffering sulfur volume fluctuation and in trapping polysulfides. Chemical vapor deposition (CVD) is today’s most widely used method to produce CNTs, which involves toxic chemicals, complex gases, and high carbon emissions, drastically increasing the overall production cost and environmental footprint.…”

“…In recent years, mobile thermal energy storage technology (TEST) based on PCMs has appeared on the market, which can adapt to the dynamic needs of customers by flexible distribution, and is considered as one of the most promising TESTs. According to their sources, PCMs can be divided into inorganic PCMs and organic PCMs. Among them, organic PCMs are widely used in waste heat recovery due to their advantages of high energy storage density, excellent thermochemical stability, low corrosion, environment-friendliness, and economy. However, most organic PCMs are typical “solid–liquid” PCMs, and they face problems such as leakage and slow charging/exothermic rate in practical applications . Due to the strong capillary adsorption, the porous materials (grapefruit peel, melamine foam, graphene, expanded graphite, etc.)…”
