Thermal corrosion behavior of Yb4Hf3O12 ceramics exposed to calcium-ferrum-alumina-silicate (CFAS) at 1400 degrees C

Ling He et al.

Summary: In this study, the interaction between CFAS deposit and Yb4Hf3O12 ceramics was investigated, and it was found that Yb4Hf3O12 ceramics exhibit high resistance to infiltration of CFAS melt. Microstructure characterization showed that a continuous reaction layer composed mainly of Yb-Ca-Si apatite formed between Yb4Hf3O12 and CFAS, inhibiting further infiltration of CFAS. Before the formation of the reaction layer, CFAS melts underwent a crystallization process, leading to the precipitation of CaYbFeAlSi-garnet, which increased the viscosity and inhibited the fluidity of CFAS.

Click-chemistry and ionic cross-linking induced double cross-linking ionogel electrolyte for flexible lithium-ion batteries

Weina Deng et al.

Summary: Due to the use of toxic, flammable, and unstable organic liquid electrolytes, commercial lithium-ion batteries fail to provide sufficient protection for the safety and long-term life of portable devices. A double cross-linking ionogel electrolyte (DC-Ionogel) was successfully created by sealing EMIm(TFSI) in a double cross-linked network using a thiolate click reaction and ion interaction. The interlaced ion cross-linking network and covalent cross-linking network significantly increased the flexibility, stability, flame retardancy, and thermal dimensional stability of the ionogel electrolyte. DC-Ionogel also exhibited superior electrochemical performance with higher room ionic conductivity (1.79 x 10- 3S cm-1) and a broader electrochemical window (5 V), making it highly suitable for flexible energy-storage devices.
