Summary: Poor ion and high electron transport at grain boundaries (GBs) of ceramic electrolytes cause lithium filament infiltration and short-circuiting in all-solid-state lithium metal batteries (ASLMBs). By reducing Li2CO3 to highly electron-conductive LiCx, lithium penetration of Li7La3Zr2O12 (LLZO) is observed. The ion and electron conductivity of LLZO GBs are simultaneously regulated using sintered Li3AlF6. LiAlO2 (LAO) infusion and F-doping at LLZO GBs significantly reduce Li2CO3 content, improve total ionic conductivity, and suppress lithium penetration. This work reveals the chemistry of Li2CO3 at LLZO GBs, presents a novel lithium penetration mechanism, and offers an innovative method for regulating ion and electron transport in garnet electrodes for advanced ASLMBs.

Summary: Understanding sulfur conversion chemistry is crucial for the development of sulfur-based high-energy-density batteries. The relationship between the electronic structure of the catalyst and its activity remains unclear. In this study, we establish a direct correlation between the p electron gain of S in p-block metal sulfides and the apparent activation energies (E-a) for the SRR, specifically the Li2Sn to Li2S conversion. The highest p charge is observed in bismuth sulfide, resulting in the lowest E-a and a high SRR rate.

Summary: The assembly of 3D structured materials from 2D units allows for the construction of thick and dense electrodes, which are highly desirable for practical energy-storage devices. The use of MXene, a 2D transitional metal carbide, shows promise in this field due to its solution-based assembly capabilities and high density. However, the lack of porous ion-transport paths poses a significant challenge in achieving high areal capacitance electrodes. In this study, a gelation-densification process initiated by hydroiodide acids (HI) is proposed, where the protons break the electrostatic balance of MXene nanosheets to trigger gelation, while HI serves as a spacer to prevent restacking of nanosheets during capillary shrinkage. The controlled evaporation of reductive HI results in a shrinking yet porous network for ion transport, leading to monoliths with a high density of 2.74 g cm(-3) and an unprecedented areal capacitance of 18.6 F cm(-2).

Summary: The poor reversibility of high-energy-density Li-S batteries is mainly caused by the polysulfide shuttling and electrode structure destruction. This study highlights the significance of Coulombic efficiency (CE) in evaluating Li-S batteries and proposes a remedy for low efficiencies by in situ coating Li2S cathode with polymerizable electrolyte additives. The coating catalytically decreases the initial overpotential of Li2S and inhibits the shuttling of lithium polysulfides, leading to improved CE and reduced sulfur loss during cycling.
