Summary: Graphite nanosheets coated by LiF/SnO2 composites are designed to achieve a lithium ion anode material with excellent performance. LiF nanoparticles play a significant role in improving the electrochemical performance by inhibiting electrolyte decomposition and providing excess Li sources during cycling, resulting in an outstanding capacity and long cycling performance. First-principles calculations demonstrate that F-doped SnO2 has a lower free energy compared to SnO2, leading to a robust composite architecture and high cycling stability.

Summary: A novel clay/cross-linked network polymer-based artificial SEI layer (NCL) is developed to prevent the formation of lithium dendrites, leading to enhanced cyclability and excellent mechanical performance in lithium metal batteries. The NCL-protected LM symmetrical cells exhibit stable cycling performance for over 1000 hours, while the NCL-Li vertical bar Cu half-cells demonstrate dendrite-free and reversible Li deposition with a high Coulombic efficiency of 99% for 170 cycles. The LiFePO4 full-cell and LiNi0.8Co0.1Mn0.1O2-coupled pouch-cells also achieve outstanding capacity retention over multiple cycles and show reliable performance under different damage conditions, highlighting the potential of NCL for practical application in high-performance LMBs.

Summary: Many aging mechanisms in Li-ion batteries occur at the electrodes, including lithium deposition at the graphite electrode during fast charging. This study proposes a non-invasive and easy-to-implement method to separate the potential of the graphite electrode from the battery voltage, using a model and battery characterization. The method has been applied to a LiFePO4/graphite battery, estimating the contributions of SEI, charge transfer, and diffusion of the graphite electrode in the battery voltage.
