“…We have often heard about phases in materials, which are inherently controlled by temperature or, more precisely, sintering temperature. The heating and cooling rates become vital in maintaining a particular phase for metallurgical applications while designing alloy; [ 55 ] the same applies to cathode materials in battery research. Furthermore, the sintering atmosphere (such as O 2 /Ar/Air/H 2 ) is another aspect that needs to be taken care of to maintain the valence state of TM.…”

Rechargeable sodium‐ion batteries (SIBs) are emerging as a viable alternative to lithium‐ion battery (LIB) technology, as their raw materials are economical, geographically abundant (unlike lithium), and less toxic. The matured LIB technology contributes significantly to digital civilization, from mobile electronic devices to zero electric‐vehicle emissions. However, with the increasing reliance on renewable energy sources and the anticipated integration of high‐energy‐density batteries into the grid, concerns have arisen regarding the sustainability of lithium due to its limited availability and consequent price escalations. In this context, SIBs have gained attention as a potential energy storage alternative, benefiting from the abundance of sodium and sharing electrochemical characteristics similar to LIBs. Furthermore, high‐entropy chemistry has emerged as a new paradigm, promising to enhance energy density and accelerate advancements in battery technology to meet the growing energy demands. This review uncovers the fundamentals, current progress, and the views on the future of SIB technologies, with a discussion focused on the design of novel materials. The crucial factors, such as morphology, crystal defects, and doping, that can tune electrochemistry, which should inspire young researchers in battery technology to identify and work on challenging research problems, are also reviewed.

In the present study, the uniaxial tensile flow stress behaviour and work hardening behaviour of AZ31B alloy has been investigated across a wide range of temperature (25 °C–250 °C) at quasi-static strain rates (10−1·s−1–10−3·s−1). The flow stress behaviour of the AZ31B sheet has been analysed at different temperatures, quasi-static strain rates and sheet orientations. It has been found that flow stress behaviour is highly influenced by the variation of temperatures, strain rates, and sheet orientations. The various important mechanical properties such as yield strength, ultimate tensile strength, percentage elongation, strain hardening exponent, and strain rate sensitivity have been determined. There has been a significant improvement in ductility (201.71%) of AZ31B alloy at 250 °C compared to 25 °C. The decrement in yield strength and ultimate strength has been found to be 47.52% and 53.66%, respectively. It has been observed that the AZ31B alloy is found to be more strain rate sensitive at elevated temperature (m = 0.11, at 250 °C) as compare to 25 °C. The various empirical hardening equations such as Hollomon, Ludwik, Ludwigson, Swift, and modified Voce have been formulated for a wide range of temperatures, strain rates, and sheet orientations. The K-M plots show three-stage of work-hardening behaviour for AZ31B alloy. Based on the performance comparison of different models, the Swift and Modified Voce efficiently predict the flow curve with correlation (more than 99%) at different temperature ranges. The fracture surface is analysed by FESEM. The quasi cleavage and river-like pattern are observed for the room temperature fractured specimen. The increase in temperature converts the mode of fracture from cleavage to ductile fracture.

Moisture, heat, and light instabilities of halide perovskites (HPs) represent a serious Achilles' heel that must be overcome, to enable future advancements in perovskite‐based optoelectronic devices such as solar cells and light‐emitting diodes. The instabilities are attributed to the unavoidable fragile ionic bonding between cationic and anionic parts of HPs during their formation. Surface passivation of HPs by various surface‐passivating materials has proven to be an attractive approach to stabilize perovskites against moisture, heat, and light, keeping intact their structural integrity and ionic bonding. Herein, the experimental and theoretical background for degradation mechanisms of HPs is reviewed along with various surface passivating materials to stabilize HPs. Finally, the existing challenges associated with thin‐film and device fabrication and an outlook for improving the stability of perovskites in optoelectronics are presented
