Double perovskites (DPs) are one of the most promising candidates for developing white light-emitting diodes (WLEDs) owing to their intrinsic broadband emission from self-trapped excitons (STEs). Translation three-dimensional (3D) DPs one-dimensional (1D) analogues, which could break octahedral tolerance factor limit, is so far remaining unexplored.

Low-dimensional lead (Pb)-free perovskite derivatives have recently been regarded as promising candidates for various optoelectronic applications because of their merits easy preparation, nontoxicity, and broadband self-trapped exciton emission. However, similar to those Pb-based metal halide perovskites, most these materials undergo an irreversible structural damage upon exposure aqueous medium, which imposes restrictions on cyclic utilization in both academic industrial fields. Herein, we...

Predicting lithium-ion batteries’ state of charge (SOC) is essential to electric vehicle battery management systems. Traditional models mainly include equivalent circuit (ECMs) and electrochemical (EMs). ECMs are based on integer-order component modeling, which cannot characterize the internal reaction mechanism battery, resulting in lower SOC prediction accuracy. In contrast, due their complex structure, EMs limited application. This study takes lithium batteries as research object proposes...
