Incorporating selenium into high-surface-area carbon with hierarchical pores, derived from red kidney bean peels via simple carbonization/activation, yields a superior Li–Se battery cathode material. This method produces framework 568 m2 g−1 surface area, significant pore volume, and improves the composite's electronic conductivity stability by mitigating volume changes reducing lithium polyselenide dissolution. The Se@ACRKB composite, containing 45 wt% selenium, shows high discharge...
Selenium (Se)-based cathode materials have garnered considerable interest for lithium-ion batteries due to their numerous advantages, including low cost, high volumetric capacity (3268 mAh cm−3), density (4.82 g ability be cycled voltage (4.2 V) without failure, and environmental friendliness. However, they electrical conductivity, coulombic efficiency, polyselenide solubility in electrolytes (shuttle effect). These factors an adverse effect on the electrochemical performance of Li-Se...
TiO2 nanoparticles (NPs) with a diameter of 100 nm were synthesized by simple hydrothermal route at 220â and then processed for possible alternate cathode catalyst material in the lithium-oxygen batteries. It was found that when utilized as cathodes, substantial improvements discharge capacity, cycle ability, rate capability low overpotential observed. This can be attributed to its high catalytic activity large surface area. Keywords: Lithium-oxygen battery, TiO2, Catalyst, Hydrothermal...
Carbon–selenium composite positive electrode (CSs@Se) is engineered in this project using a melt diffusion approach with glucose as precursor, and it demonstrates good electrochemical performance for lithium–selenium batteries. X-ray diffraction (XRD) scanning electron microscopy (SEM) EDS analysis are used to characterize the newly designed CSs@Se electrode. To complete evaluation, characterization such charge–discharge (rate cycle stability), cyclic voltammetry (CV), impedance spectroscopy...

With the increasing demand for advanced energy storage systems, lithium-selenium (Li-Se) batteries have emerged as a promising alternative to lithium-sulfur (Li-S) batteries, offering high density, cost-effectiveness, and environmental friendliness. However, practical implementation of Li-Se encounters several challenges, including low active material utilization, poor electrical conductivity, rapid capacity degradation, lithium polyselenide (LiPSe) shuttle effect. In this study, we address...
