Summary: Composite catalysts Pd/B,N-CDs@CNT were designed by immobilizing Pd nanoparticles on a hybrid support composed of B,N-doped carbon dots (B,N-CDs) and multi-wall carbon nanotubes (CNT). The Pd nanoparticles showed clean surface, low crystallinity, and surface distortion. The catalyst exhibited significantly enhanced oxygen reduction reaction (ORR) activity, about 5-6 times higher than commercial Pt/C, mainly attributed to the unique microstructure of Pd nanoparticles. The composite B,N-CDs and doped B,N heteroatoms further improved the ORR performance through more absorption sites, facilitating electron transfer, promoting adsorption of oxygenated species, and weakening the interaction between Pd and C.

Summary: LiNixCoyMn1-x-yO2 (NCM) is a critical cathode material for lithium-ion batteries in electric vehicles. The aging of cathode/electrolyte interfaces leads to capacity degradation and long-term cycle instability. A novel neural network model called ACGNet is developed to predict electrochemical stability windows of crystals, allowing for high-throughput screening of coating materials. LiPO3 is identified as a promising coating material with high oxidation voltage and low cost, which significantly improves the cycle stability of NCM batteries. This study demonstrates the accuracy and potential of machine learning in battery materials.
