Rational Regulation of Electron-Deficient Cobalt Centers via p-π Conjugation for High-Performance Li-S Batteries

【Research Background】 Lithium-sulfur (Li-S) batteries are considered one of the most promising new secondary battery systems due to their high theoretical energy density, low cost, and environmental friendliness. However, their practical application is limited by challenges such as the shuttling effect caused by soluble polysulfides (LiPSs) and the kinetic hysteresis of the sulfur reduction reaction … Read more

Systematic Summary of Spin Effects in Dual-Atom Electrocatalysts by the Team of Guan Jingqi at Jilin University

Overview Developing high-efficiency atomic-level catalysts for energy conversion and storage technologies is crucial for addressing energy shortages. The spin states of dual-atom catalysts (DAC) are closely related to their catalytic activity. Adjusting the spin state of the active center in DAC can directly alter the occupancy of the d orbitals, thereby affecting the bonding strength … Read more
