Tailoring the interfacial interaction in SiC-based anode materials is crucial to accomplishment of higher energy capacities and longer cycle lives for lithium-ion storage. In this paper, atomic-scale tunable achieved by epitaxial growth high-quality N doped graphene (NG) on SiC (NG@SiC). This well-designed NG@SiC heterojunction demonstrates an intrinsic electric field with intensive interaction, making it ideal prototype thoroughly understand configurations electron/ion bridges mechanisms...
In the quest for high-capacity battery electrodes, addressing capacity loss attributed to isolated active materials remains a challenge. We developed an approach substantially recover in silicon electrodes and used voltage pulse reconnect lithium-silicon (Li
High-performance, practical all-solid-state batteries (ASSBs) require solid-state electrolytes (SSEs) with fast Li-ion conduction, wide electrochemical stability window, low cost, and mass density. Recent density functional theory (DFT) simulations have suggested that lithium thioborates are a particularly promising class of materials for high-performance SSEs in Li batteries, but these not been studied extensively experimentally due to synthesis difficulty. Particularly, their properties...
The solid electrolyte interphase (SEI) plays a key role in the aging of lithium-ion batteries. engineering advanced negative electrode materials to increase battery lifetime relies on accurate models SEI growth, but quantitative measurement growth rates remains challenging due their nanoscale heterogeneity and environmental sensitivity. In this work, using operando electrochemical atomic force microscopy, we track copper carbonate electrolyte. From measurements thickness irreversible...
Abstract Typical models of polycrystalline ionic materials treat the grain boundary properties as single valued, without consideration full range values that define macroscopically measured average. Here a unique experimental platform suitable for local multimodal characterization individual boundaries in bicrystal fibers is reported. A variation three orders magnitude conductivity ceria observed, across six bicrystals by both alternating current impedance spectroscopy and direct (D.C.)...
Sn is a promising metal anode for aqueous batteries due to its dendrite-free plating, large hydrogen evolution overpotential, and high theoretical capacity with up four-electron redox per atom. However, practically achieving the remains challenging, only limited cell energy densities demonstrated thus far. We validate kinetically asymmetric [Sn(OH)6]2-/Sn pathway involving direct plating stepwise 2+2 electron stripping through [Sn(OH)3]- intermediate, which decreases Coulombic efficiency...
In this paper, 1D In2Te3 nanowires were synthesizes through a simple solvothermal approach. The morphology was first studied by scanning electron microscopy (SEM) and Transmission (TEM). From the results, have diameter from 100 to 200 nm length of dozens microns. X-ray Diffraction (XRD), photoelectron spectroscopy (XPS) Raman spectrum used study composition, crystal structures, optical property. Based on typical nanowire sample, experiment factors changed synthsize other samples in order...
Contact loss and current constriction pose significant challenges at the Li metal interface of solid-state batteries. For garnet-structured Li7La3Zr2O12 (LLZO), these effects are amplified by Li+/H+ exchange surface contamination reactions, which lead to conductivity losses poor wetting. In this study, we utilize a variety treatment processes across 37 cells selectively induce proton reactions in LLZO. The resulting bulk chemistry is systematically characterized correlated changes...
Lithium metal electroplating and short-circuiting limit fast charging in solid-state batteries, yet the mechanisms methods to regulate lithium intrusions are not well-understood. In this work, we discover that nanoscale heterogeneous Ag+ doping dramatically affects intrusion Li6.6La3Zr1.6Ta0.4O12 (LLZO), a brittle solid electrolyte. We generate by thermally annealing 3-nm-thick metallic film. The Ag undergoes Ag-Li ion exchange, completely disappears, diffuses into LLZO bulk grain boundaries...

A four-ball tester was used to evaluate the tribological performances of bismuth naphthenate (BiNap), sulfurized isobutene (VSB), and their combinations. The results show that antiwear properties BiNap VSB are not very visible, but they possess good extreme pressure (EP) properties, particularly sulfur containing additives. Synergistic EP with various sulfur-containing additives were investigated. indicate exhibits synergism surface analytical tools, such as X-ray photoelectron spectrometer...
