Summary: Solid-state lithium metal batteries (SSLMBs) have potential for high safety and energy density, but the growth of lithium dendrite in solid electrolytes limits their practical applications. This study develops a simple heat treatment method to revive and recycle garnet oxide electrolytes with Li dendrite penetration. The recovered garnet electrolyte shows higher relative density, enhanced ionic conductivity, and improved critical current density compared to the pristine one. Thermal healing is attributed to the reaction products between dendritic Li metal and air, contributing to further densification of garnet electrolytes during heat treatment.

Summary: The solid electrolyte interphase (SEI) plays a critical role in determining the interfacial stability of lithium metal anode. Research compared a diluted electrolyte and a super-concentrated electrolyte, finding that the latter results in a more compact SEI structure due to reduced solubility and outstanding formation kinetics. This work provides new insights into the superior performance of super-concentrated electrolyte in lithium metal batteries.

Summary: In this study, the mechanism of lithium dendrite penetration in solid-state electrolyte (SE) and its suppression strategies were investigated using a new phase field (PF) model. The results showed that the high stress-intensity factor caused by high hydrostatic pressure in lithium was not inhibited by the high stiffness of SE. The increase in Young's module of SE even made the stress-intensity factor more significant. Considering the mechano-electrochemical coupling (MEC) effects, the increase in SE's Young's module had a competing effect on dendrite penetration, causing a nonmonotonic change in dendrite length. The evaluation of dendrite suppression by toughening SE revealed a critical fracture surface energy density of SE and the effectiveness of engineering compressive traction in inhibiting dendrite penetration.

Summary: Investigating the growth of lithium dendrites is crucial for the commercialization of lithium metal batteries. This study employs phase field modeling to analyze the effects of anisotropy strength, applied voltage, nucleation spacing, and stripping on lithium dendrite growth. Results show that the growth of lithium dendrites is slower and results in shorter and narrower shapes under pulse-voltage charging mode compared to constant-voltage charging mode. These findings offer valuable insights for restraining the undesired growth of lithium dendrites.

Summary: The composite separator PP-CPE is created by coating the PP separator with the composite polymer electrolyte (CPE) made from LLZTO and PVDF-HFP. The PP-CPE separator features rapid Li+ channels at the interfaces of PVDF-HFP, LLZTO, and PVDF-HFP/LLZTO to compensate for the inequalities in Li+ flux movement. The modification strategy improves coulombic efficiency and cycle stability by reducing the growth of lithium dendrites.

Summary: The addition of Li3InCl6 in nonaqueous electrolytes can form a ternary composite solid electrolyte interphase (SEI) that effectively suppresses lithium dendrite growth in lithium metal batteries, maintaining stable long-term cycling performance. This approach leads to dendrite-free metal anodes, as demonstrated in symmetric Li|Li batteries and full batteries with a LiFePO4 cathode, achieving a stable capacity retention of 95% after 500 cycles. Furthermore, the Li vertical bar S battery with Li3InCl6-added LiTFSI in 1,3-dioxolane/1,2-dimethoxyethane electrolyte shows significant improvement in capacity retention at 0.5 C.

Summary: This study investigated the adsorption behavior of thiadiazole derivatives on pure Cu and Ag surfaces using first-principles calculations. The results showed that the average adsorption energy of 2,5-dimercapto-1,3,4-thiadiazole (DMTD) was significantly lower than that of 1,3,4-thiadiazole (TD) on both Cu and Ag surfaces. This difference was attributed to the removal of H atoms from DMTD in the calculations and the presence of additional sulfur atoms in the DMTD structure as anchoring sites.

Summary: A physical model was developed to understand the conductive filament (CF) formation and growth behavior in metal-oxide-based resistive random-access memories (RRAM). The study found that active electrodes with lower oxygen vacancy formation energy and oxides with small Lorenz number can enable CF formation at lower electroforming voltage and create a CF with more homogeneous morphology. This work advances our understanding of CF formation and growth during the electroforming process and can guide the selection of oxide and electrode materials for more stable and functional RRAM.

Summary: A highly stable Zn metal anode is designed by reconstructing its surface with a self-assembled nanoporous polyelectrolytic interlayer. This layer acts as a physical barrier reducing the contact between Zn metal and water molecules, suppressing hydrogen evolution and Zn corrosion. The unique nanostructures and chemical compositions of the interlayer ensure fast Zn plating/stripping kinetics and homogeneous growth of Zn deposits, resulting in significantly prolonged cycle life and low voltage hysteresis.
