Article Abstract
Employing lithium-rich layered oxide (LLO) as the cathode of all-solid-state batteries (ASSBs) is highly desired for realizing high energy density. However, the poor kinetics of LLO, caused by its low electronic conductivity and significant oxygen-redox-induced structural degradation, has impeded its application in ASSBs. Here, the charge transfer kinetics of LLO is enhanced by constructing high-efficiency electron transport networks within solid-state electrodes, which considerably minimizes electron transfer resistance. In addition, an infusion-plus-coating strategy is introduced to stabilize the lattice oxygen of LLO, successfully suppressing the interfacial oxidation of solid electrolyte (Li InCl ) and structural degradation of LLO. As a result, LLO-based ASSBs exhibit a high discharge capacity of 230.7 mAh g at 0.1 C and ultra-long cycle stability over 400 cycles. This work provides an in-depth understanding of the kinetics of LLO in solid-state electrodes, and affords a practically feasible strategy to obtain high-energy-density ASSBs.

Cell-to-cell spread is a major mechanism used by the bacterial pathogen to disseminate within its host. In this mechanism, bacteria are directly transferred from the cytosol of an infected donor cell to a recipient cell via formation of an intercellular protrusion. The intercellular protrusion resolves into a vacuole that is disrupted by to reach the cytosol of the recipient cell, where it divides and starts new cell-to-cell spread cycles.

Lithium-rich layered oxide (LLO) cathodes are expected to overcome the energy density limitations, but their applicability is hindered by low initial Coulombic efficiency (ICE) and unstable electrode-electrolyte interphases with sluggish kinetics. Here an elaborate electrophilic electrolyte is proposed that effectively stabilizes the surface lattice oxygen of the LLO cathode, facilitates the formation of dense and fast-ion-transport electrode-electrolyte interphases, and prevents Li-dendrites on the anode. The nucleophilic reaction mechanism driven by the electrolyte enables LLO to exhibit a reversible capacity of 310 mAh g with a record ICE of 100%, as well as impressive 3C fast-charging stability, remarkably superior to that in the basic electrolyte.

Listeriolysin O (LLO) is a potent membrane-damaging pore-forming toxin (PFT) secreted by the bacterial pathogen . LLO belongs to the family of cholesterol-dependent cytolysins (CDCs), which specifically target cholesterol-containing cell membranes to form oligomeric pores and induce membrane damage. CDCs, including LLO, harbor designated pore-forming motifs.

Elemental doping is widely used to improve the performance of cathode materials in lithium-ion batteries. However, macroscopic/statistical investigation on how doping sites are distributed in the material lattice, despite being a key prerequisite for understanding and manipulating the doping effect, has not been effectively established. Herein, to solve this predicament, a universal strategy is proposed to quantitatively identify the locations of Al and Mg dopants in lithium-rich layered oxides (LLOs).

Biomolecular interaction acts a pivotal part in understanding the mechanisms underlying the development of Alzheimer's disease (AD). Herein, we built a biosensing platform to explore the interaction between gelsolin (GSN) and different β-amyloid protein 1-42 (Aβ) species, including Aβ monomer (m-Aβ), Aβ oligomers with both low and high levels of aggregation (LLo-Aβ and HLo-Aβ) via dual polarization interferometry (DPI). Real-time molecular interaction process and kinetic analysis showed that m-Aβ had the strongest affinity and specificity with GSN compared with LLo-Aβ and HLo-Aβ.
