Summary: In response to the demand for LIBs, a solvent-free manufacturing technology is demonstrated to avoid toxic organic solvents and improve electrode structures. The dry-printed (DP) electrodes have lower tortuosity, allowing for better rate performance and higher capacity retention compared to slurry cast (SL) electrodes. The coating layer on active materials in DP cells prevents side reactions and prolongs cycle life. This roll-to-roll manufacturing process has immense potential for scalable and efficient battery production.

Summary: Compared with traditional lithium-ion batteries and Li-other group VIA elements batteries, Li-Te batteries have high specific volumetric capacity and superior electrical conductivity, making them important for portable electronics and electric vehicles. However, their Achilles’ heel is the huge volume change and dissolution of polytellurides during cycling. In this research, a cathode material based on Te-filled CNTs was synthesized, which showed improved reaction kinetics and electrochemical reversibility. The use of nanoscale cavities in the CNTs stabilized the polytellurides and enhanced the utilization and cycling stability of the cathodes in Li-Te batteries.

Summary: In this study, the researchers constructed a metal-organic framework, UIO-66-NH2, containing Lewis base sites, and comprehensively investigated the pivotal mechanism of Lewis base sites in promoting the electrocatalytic reaction processes of lithium-oxygen batteries (LOBs). The density functional theory (DFT) calculations showed that the Lewis base sites acted as electron donors and enhanced the activation of O-2/Li2O2 during the discharged-charged process, leading to accelerated reaction kinetics of LOBs. Moreover, in situ Fourier transform infrared spectra and DFT calculations demonstrated that the Lewis base sites converted the Li2O2 growth mechanism from surface-adsorption growth to solvation-mediated growth by capturing Li+, thus weakening the adsorption energy of UIO-66-NH2 towards LiO2. The LOB based on UIO-66-NH2 showed high discharge specific capacity, low discharged-charged overpotential, and long cycling life.
