The development of flexible supercapacitors(FScs) capable of operating at high temperatures is crucial for expanding the application areas and operating conditions of supercapacitors. Gel polymer electrolytes and electrode materials stand as two key components that significantly impact the efficacy of hightemperature-tolerant FScs(HT-FScs). They should not only exhibit high electrochemical performance and excellent flexibility, but also withstand intense thermal stress. considerable efforts have been devoted to enhancing their thermal stability while maintaining high electrochemical and mechanical performance. In this review, the fundamentals of HT-FScs are outlined. A comprehensive overview of state-of-the-art progress and achievements in HT-FScs, with a focus on thermally stable gel polymer electrolytes and electrode materials is provided. Finally, challenges and future perspectives regarding HT-FScs are discussed, alongside strategies for elevating operational temperatures and *** review offers both theoretical foundations and practical guidelines for designing and manufacturing HT-FScs, further promoting their widespread adoption across diverse fields.

A low gate voltage operated multi-emitter-dot gated lateral bipolar junction transistor （BjT） ion sensor is proposed. The proposed device is composed of an arrayed gated lateral BjT, which is driven in the metal-oxidesemiconductor field-effect transistor （MOSFET）-BjT hybrid operation mode. Further, it has multiple emitter dots linked to each other in parallel to improve ionic sensitivity. Using hydrogen ionic solutions as reference solutions, we conduct experiments in which we compare the sensitivity and threshold voltage of the multi-emitter-dot gated lateral BjT with that of the single-emitter-dot gated lateral BjT. The multi-emitter-dot gated lateral BjT not only shows increased sensitivity but, more importantly, the proposed device can be operated under very low gate voltage, whereas the conventional ion-sensitive field-effect transistors cannot. This special characteristic is significant for low power devices and for function devices in which the provision of a gate voltage is difficult.

Transition metal-based nanomaterials have emerged as promising electrocatalysts for oxygen evolution reaction（OER）. considerable research efforts have shown that self-reconstruction occurs on these nanomaterials under operating conditions of OER process. However, most of them undergo incomplete reconstruction with limited thickness of reconstruction layer, leading to low component utilization and arduous exploration of real catalytic mechanism. Herein, we identify the dynamic behaviors in complete reconstruction of co-based complexes during OER. The hollow phytic acid（PA） cross-linked coFe-based complex nanoboxes with porous nanowalls are designed because of their good electrolyte penetration and mass transport ability, in favor of the fast and complete reconstruction. A series of experiment characterizations demonstrate that the reconstruction process includes the fast substitution of PA by OH-to form co（Fe）(OH)xand subsequent potential-driven oxidation to co（Fe）OOH. The obtained coFeOOH delivers a low overpotential of 290 mV at a current density of 10 mA cm-2and a long-term *** experiment results together with theory calculations reveal that the Fe incorporation can result in the electron rearrangement of reconstructed coFeOOH and optimization of their electronic structure,accounting for the enhanced OER activity. The work provides new insights into complete reconstruction of metal-based complexes during OER and offers guidelines for rational design of high-performance electrocatalysts.
