Summary: This study addresses the major challenges in solid-state Li metal batteries (SSLMBs) by using a functional gradient Li anode (FGLA), which reduces the interface resistance and suppresses Li dendrite growth. The FGLA not only dramatically reduces the resistance at the interface, but also increases the critical current density, showing excellent cycling performances with different cathode materials.

Summary: A key challenge in lithium-ion batteries is the instability of electrolytes against anode materials, with the solid-electrolyte interphase (SEI) providing stability at the cost of capacity consumption. Artificial SEIs offer more flexibility to tune properties such as chemical composition and impedance, but must ensure sufficient transport properties for Li-ions and stability.

Summary: This study explores the ion desolvation processes with and without solid electrolyte interphases (SEIs) using quantum chemistry calculations. It is found that the accelerated ion desolvation in new-concept electrolytes is mainly attributed to SEIs rather than the regulated solvation structure. Based on this understanding, an SEI-aided ion desolvation model is proposed, bridging the SEI and battery kinetics at the atomic scale and redefining the functions of SEIs, which are expected to guide the electrolyte design in batteries.

Summary: Structural reorganization of sparingly solvating electrolytes (SSEs) using aromatic anti-solvents is crucial for taming the quasi-solid-state sulfur reaction and improving reaction kinetics. The use of aromatic anti-solvents disrupts the electrolyte structure, accelerates sulfur consumption and re-formation, and promotes the formation of a robust solid electrolyte interphase (SEI) on lithium metal.

Summary: Increasing the cut-off voltage of cathodes improves the energy density of Li||LiCoO2 batteries, but also leads to rapid battery degradation due to oxidation and deterioration. However, by using bis-(benzenesulfonyl)imide (BBSI) as an additive, a uniform and highly Li+ conductive cathode electrolyte interphase (CEI) is constructed, which stabilizes the batteries at 4.6 cut-off voltage and exhibits superior cycling and high-rate performance. The CEI, consisting of LiF and conductive Li+ moieties, improves Li+ migration, alleviates cathode degradation, and reduces other secondary degradation factors. Li||LiCoO2 batteries with 1% BBSI-containing electrolyte sustain 81.30% of initial capacity after 300 cycles at 0.5C, and 88.27% of initial capacity even after 500 cycles at 2C/3C.

Summary: Li2OHCl is a promising solid-state electrolyte for all-solid-state Li-ion batteries. Strain engineering, achieved through isovalent doping, can improve Li+ conductivity and stabilize the highly conductive cubic phase at room temperature. By introducing tensile strain, Li2OHCl0.921I0.079 achieves a significantly higher ionic conductivity and demonstrates enhanced battery performance compared to Li2OHCl.

Summary: This study investigates the effect of strain on Li+ transport and finds that tensile strain can decrease the migration energy barrier. Tensile strain not only enhances conductivity but also stabilizes the highly conductive cubic phase at room temperature. An optimized composition (Li2OHCl0.921I0.079) achieves an ionic conductivity of 0.50 mS cm-1 at 373 K, five times larger than that of Li2OHCl. Furthermore, introducing tensile strain improves the Li+ conductivity and simultaneously stabilizes the cubic phase at low temperatures, resulting in significantly enhanced battery performance.

Summary: As the aircraft industry becomes more focused on sustainable aviation, there is increasing interest in hybrid-electric propulsion systems with batteries that have higher energy density to reduce fuel consumption. Next-generation chemistries like oxide-based all-solid-state Li-battery (ASSB) technologies could benefit future aircrafts. However, it is time- and resource-intensive to experimentally produce and evaluate a wide range of design parameters for maximizing the energy density of ASSB. Physics-based modeling offers a more efficient way to identify optimal designs for battery cells with high energy density.

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.
