Summary: The addition of acrylonitrile (AN) in carbonate-based electrolytes has been reported as an effective method to achieve uniform and dense lithium (Li) deposition and improve the coulombic efficiency of Li metal anodes. The electrochemical, spectroscopic, and theoretical studies show that AN is cathodically electropolymerized on the Li surface, forming a polyacrylonitrile artificial solid electrolyte interface that allows for uniform nucleation and growth of Li deposition with reduced side reactions. The effectiveness of AN additive is demonstrated in Li pouch cells with excellent cycle stability under realistic charge-discharge conditions.

Summary: Lithium-ion batteries (LIBs) are widely used in modern electronics and electric vehicles due to their high energy and power densities, cycle-life, and safety. This study presents a simple method to improve the high-voltage charge capability of LIBs by applying an artificial cathode-electrolyte interface (Li+-ACEI) on the state-of-the-art cathode, LiCoO2 (LCO). The application of Li+-ACEI using a superionic ceramic Li+ ion conductor, lithium aluminum germanium phosphate (LAGP), results in reduced charge-transfer resistance, higher discharge capacity, higher Coulombic efficiency, and higher rate capability of the LCO cathodes.

Summary: The study focused on designing Pt-based nanoparticle catalysts with ordered arrays for enhanced oxygen reduction reaction (ORR) activity. The PtCo@Pt core-shell NP arrays showed higher ORR activity and durability compared to conventional Pt/C catalysts, achieving higher current density and peak power density in single-cell performance tests. Density functional theory calculations indicated that PtCo@Pt NPs had superior ORR activity due to a lower d-band center and weaker oxygen binding energy than Pt and PtCo.
