Summary: The addition of KPF6 in the electrolyte can promote the formation of a robust SEI layer, effectively inhibiting the growth of Li dendrites. The KPF6 additive can form a thin and durable SEI layer rich in LiF, which blocks the electron leakage pathways. Additionally, KPF6 additive can reside at defect sites, hindering the incoming of Li+ and restricting the growth of Li dendrites. Optimizing the electrode/electrolyte interphase by controlling the concentration of additives has implications for fast charging.

Summary: To address the issue of lithium (Li) plating on graphite anodes during fast charging, Li plating regulation and morphology control are proposed. A Li plating-reversible graphite anode is achieved through a localized high-concentration electrolyte (LHCE), resulting in high reversibility and stability. The stable LiF-rich solid electrolyte interphase (SEI) enables a higher average Coulombic efficiency (99.9%) and reversibility of Li plating (99.95%). A self-made LiNi0.5Mn0.3Co0.2O2 | graphite pouch cell exhibits a competitive capacity retention of 84.4% even at high current (7.2 A) after 150 cycles, demonstrating the potential for high-performance fast-charging batteries.

The introduction of VC and azodiisobutyronitrile results in the formation of abundant poly(VC) in the solid electrolyte interphase, which improves the thermal stability of SEI. This electrolyte not only prevents direct contact between electrodes, but also reduces exothermic reactions between electrodes and electrolytes, thus increasing the thermal safety of the batteries.

Summary: The solid-electrolyte interphase (SEI) in lithium (Li) metal batteries is often heterogeneous and mechanically unstable. In this study, a bilayer SEI with improved homogeneity and mechanical stability is designed using trioxane-modulated electrolytes. The coin cell with the tailored bilayer SEI achieves 430 cycles, while the cell with an anion-derived SEI undergoes only 200 cycles. The development of a homogeneous and mechanically stable SEI expands the cyclability of high-energy-density lithium metal batteries.

Summary: Rational electrolyte design is proposed by regulating the solvation structure in localized high-concentration electrolytes (LHCE) through weakening the solvating power of solvents. The use of 1,3-dimethoxypropane (DMP) solvent leads to the formation of nanometric aggregates (AGG-n) where an anion coordinates to more than two Li-ions in LHCE. The Li metal batteries with DMP-based LHCE demonstrate significantly improved cycle life and high energy density compared to advanced ether-based LHCE under demanding conditions.
