“…Meanwhile, the phase change peaks at high temperatures became more enhancive, which manifested that the incremental SA in the SA ++ /SG 5 had mainly contributed to the phase change enthalpy occurring at the high temperatures. With increasing the content of SA, the crystallinities of SA in composites were enhanced to 86.25% and 88.44% for SA + /SG 5 and SA ++ /SG 5 , respectively.…”

Novel thermal energy storage materials were synthesized from graphene-decorated silica (SG) and stearic acid (SA) by vacuum impregnation method. Three kinds of SG (SG 1 , SG 5 , and SG 10 ) were prepared by decorating silica with different contents of graphene and were then used to stabilize SA to prepare SA/ SG 1 , SA/SG 5 , and SA/SG 10 composites. The structures and thermal energy storage performances of the SA/SG composites were investigated. It is of interest that the thermal energy storage behaviors of the SA/ SG composites were dramatically changed with different contents of graphene, presenting more than one endothermal or exothermal peak in the differential scanning calorimetry (DSC) curves while pure SA had only one. The SA in SA/SG 1 and SA/SG 5 showed higher crystallinity (F c , 84.44% and 84.39%) and greater effective energy storage per unit mass (E ef , $150 J g À1 ) than that of SA in SA/SG 10 . These thermal energy storage behaviors and properties were revealed to be related to the pore structures of the SG.The thermal stability of the SA/SG composites was analyzed by a thermogravimetric analyzer (TGA), and the SA/SG composites have good thermal stability. Addition of graphene was beneficial to the enhancement in thermal conductivity of the SA/SG composite, which could reach 0.90 W m, and 1.12 W m À1 K À1 for SA/SG 1 , SA/SG 5 , and SA/SG 10 , respectively; and were 246%, 304%, and 331% higher than pure SA, respectively. SA/SG 5 has potential for application in thermal energy storage, especially in thermal gradients due to it having both high E ef and thermal conductivity.

Although recently developed hybrid zinc (Zn) batteries integrate the benefits of both alkaline Zn and Zn-air batteries, the kinetics of the electrocatalytic oxygen reaction and mass transfer of the electrolyte, which are limited by the mismatched and disordered multiphase reaction's interfacial transfer channels, considerably inhibit the performance of hybrid Zn batteries. In this work, novel, continuously oriented three-phase interfacial channels at the cathode derived from the natural structure of pine wood are developed to address these challenges. A pine wood chip is carbonized and asymmetrically loaded with a hydrophilic active material to achieve the creation of a wood-derived cathode that integrates the active material, current collector, and continuously oriented three-phase reaction interfacial channels, which allows the reaction dynamics to be accelerated. Consequently, the assembled quasi-solid-state hybrid battery performs an extra charge-discharge process beyond that performed by a typical nickel (Ni)-Zn battery, resulting in a wide operating voltage range of 0.6-2.0 V and a superior specific capacity of 656.5 mAh g -1 , in addition to an excellent energy density (644.7 Wh kg -1 ) and good durability. The ≈370% capacity improvement relative to the Ni-Zn battery alone makes the hybrid battery one of the best-performing alkaline Zn batteries.
