Solid electrolytes (SEs) can potentially address the inherent safety problems of conventional organic liquid electrolytes. However, their low ionic conductivity and large interfacial resistance limit the practical applications of SEs. Here, a flexible solid electrolyte with a multilayer structure is fabricated by the UV curing of an interpenetrating network of poly(ether‐acrylate) (ipn‐PEA) in the Na3Zr2Si2PO12/poly(vinylidene fluoride‐hexafluoropropylene) porous skeleton (NZSP/PVDF‐HFP), exhibiting a high Na+ transference number of 0.63 and a suitable ionic conductivity of above 10−4 S cm−1 at 60 °C. In addition, due to the unique structure of the internal rigidity and external flexibility, the composite solid electrolyte can effectively mitigate interfacial ion transfer issues while guaranteeing a certain mechanical strength, and largely inhibiting the formation of dendrite and dead sodium. The solid sodium metal batteries using Na3V2(PO4)3 (NVP) as a cathode possess a discharge capacity of 85 mA h g−1 after 100 cycles at 0.5 C, and achieve above 90% of capacity retention rate during 100 cycles at 0.1 C for Na2/3Ni1/3Mn1/3Ti1/3O2 (NTMO) at 60 °C. The flexible solid electrolyte with multilayer structure shows a great advantage for managing the ionic conductivity and interface resistance problem, suggesting a promise as a practical sodium metal battery.

“…The purpose of thermal energy storage (TES) is to store heat under specific conditions and release it at a later stage when required . Sensible energy storage, latent energy storage, and chemical energy storage are all included in TES. The use of phase change materials (PCMs) is an effective latent energy storage technique because of the large storage capability, high thermal conductivity, and isothermal phase transition temperature PCMs have .…”

Summary A composite phase change material (PCM) of copper‐doped polyethylene glycol (PEG) 2000 impregnated urchin‐like porous titanium dioxide (TiO2) microspheres (PEG/TiO2) was successfully synthesised. The urchin‐like porous TiO2 structures contain hollow cavities that can provide a high PEG loading capacity of up to 80 wt%. Copper nanoparticles were uniformly dispersed on the outer and inner surfaces of the 0.8PEG/TiO2 as additives to enhance the thermal conductivity of the composite PCM. The latent heat of the Cu/PEG/TiO2 porous composite PCM reached 133.8 J/g, and the thermal conductivity was 0.58 W/(mK), which was 152.2% higher than that of TiO2 and 38.1% higher than 0.8PEG/TiO2. Moreover, the Cu/PEG/TiO2 porous composite PCM has excellent thermal stability and reliability.

“…So, it is wise to convert atmospheric CO 2 into small organic molecules by photoelectrochemical method, such as CO, HCOOH, CH 3 OH, C 2 H 4 and CH 3 CH 2 OH, etc., especially driven by solar or wind power sources . Such an attractive strategy can not only slow down the accumulation of CO 2 in the atmosphere, but also produce useful chemical materials, alleviating our dependence on conventional fossil energy sources . But high energy required, high overpotential, and low selectivity are still the main obstacles for the CO 2 reduction reaction (CO 2 RR) .…”

Photoelectrochemical reduction of CO2 to value‐added chemicals and fuels is an attractive strategy to store renewable energy and mitigate greenhouse gas emissions. In this study, based on the density functional theory (DFT) calculation, a two‐dimensional nanostructure MoS2 loaded on SnO2 nanoparticles (MS/SON) was prepared for photoassisted electrocatalytic reduction of CO2 to HCOOH through a two‐step process of facile hydrothermal and pyrolysis method. Through physical structure characterization and photoelectric performance test, the results indicated that the 5 % MS/SON exhibits exclusive HCOOH selectivity, the maximum FE is 43.8 %, the current density reached to 9 mA cm−2 at −1.4 V and the photocurrent value is 12.5 μA cm−2 under 0.5 V bias. The overpotential is as low as 245 mV. Besides, after the introduction of MoS2, there is a red shift in the adsorption band edge from 380 nm to 500 nm, indicating an enhancement of light response; the peak intensity of photoluminescence (PL) decreased, showing that the electron and hole are effectively separated; the values of electrochemical impedance spectroscopy (EIS) and Tafel plots (70 mV dec−1) were smaller than other ratios, demonstrating that the faster charge transfer rate; the proper introduction of MoS2 increased the specific surface area from 47.64 m2 g−1 to 55.99 m2 g−1, which was helpful to expand the number of active sites. It is demonstrated that MS/SON is an excellent CO2 reduction material.
