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.

Summary: This study investigates the synergistic effect of functional alloying structure and Li+ solvation mediated interfacial kinetic on lithium metal protection. By constructing a Li alloy matrix with a bi-functional silver-Li3N blended interface, fast Li+ conductivity and high Li affinity can be achieved, leading to decreased nucleation and mass transfer-controlled overpotentials. Additionally, the inward diffusion depth of Li adatoms inside Ag sites can be limited by the Li+ solvation structure, thus elongating the Li protection ability of the Ag-Li3N interface.

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: Polymeric conducting binders have significant research value as they can serve as both binders and conducting agents, increasing the proportion of active materials in batteries and the volumetric energy density. This study explores the potential of a composite of PEDOT:PSS and polyethylene glycol (PEG) as a high-performing binder for silicon anodes. The addition of PEG polymer enhances the conductivity of PEDOT:PSS and improves the mechanical properties of the silicon anode, resulting in extended cycle endurance. The use of operando optical microscopy allows for direct observation of the binder's operation. Consequently, the bifunctional PEDOT:PSS/PEG binder shows promise for high-performance lithium-ion battery binders.

Summary: Metal fluorides as conversion-reaction cathodes have advantages such as low cost, environmentally friendly, and high energy density. In this study, a hydroxyl-rich copper fluoride (Cu2(OH)3F) was proposed as a conversion cathode, coupled with an electrolyte additive engineering, to address the poor reversibility issue. The presence of OH in Cu2(OH)3F enables effective suppression of Cu+ dissolution, resulting in better reaction reversibility and kinetics.
