Solid-state electrolytes (SSEs) are receiving great interest because their high mechanical strength and transference number could potentially suppress Li dendrites electrochemical stability allows the use of high-voltage cathodes, which enhances energy density safety batteries. However, much lower critical current easier dendrite propagation in SSEs than nonaqueous liquid hindered possible applications. Herein, we successfully suppressed growth by situ forming an LiF-rich solid electrolyte...
Abstract In carbonate electrolytes, the organic–inorganic solid electrolyte interphase (SEI) formed on Li‐metal anode surface is strongly bonded to Li and experiences same volume change as Li, thus it undergoes continuous cracking/reformation during plating/stripping cycles. Here, an inorganic‐rich SEI designed a reduce its bonding energy with metal by dissolving 4 m concentrated LiNO 3 in dimethyl sulfoxide (DMSO) additive for fluoroethylene‐carbonate (FEC)‐based electrolyte. Due aggregate...
Graphene hydrogel/nickel foam composite electrodes for high-rate electrochemical capacitors are produced by reduction of an aqueous dispersion graphene oxide in a nickel (upper half figure). The micropores the hydrogel exposed to electrolyte so that ions can enter and form double-layers. framework shortens distances charge transfer. Therefore, capacitor exhibits highrate performance (see plots). Detailed facts importance specialist readers published as ”Supporting Information”. Such...
An improved hydrothermal process is developed to fabricate macroporous graphene monoliths (MGMs) using a soft template of organic droplets. The MGMs are constructed from closed-cell distorted spherical pores. This unique microstructure makes that have low weight densities, good electrical conductivities, and excellent elasticity with rapid recovery rates. As service our authors readers, this journal provides supporting information supplied by the authors. Such materials peer reviewed may be...
Abstract All‐solid‐state Li metal batteries have attracted extensive attention due to their high safety and energy density. However, dendrite growth in solid‐state electrolytes (SSEs) still hinders application. Current efforts mainly aim reduce the interfacial resistance, neglecting intrinsic dendrite‐suppression capability of SSEs. Herein, mechanism for formation dendrites is investigated, Li‐dendrite‐free SSE criteria are reported. To achieve a capability, SSEs should be thermodynamically...
Electrochemical capacitors (ECs) have been widely applied in electronics, electric vehicles, aircrafts, energy storage devices, uninterrupted or emergency power supplies, and so on. An ideal EC should high and/or powder density, good rate capability, long cycling life. Recently, graphene, graphene derivatives, their composites explored as the electrode materials of ECs to satisfy these requirements. In this Perspective, we review recent development synthesizing for discuss strategies...

Molecular dynamics simulations show that...
Engineering a stable solid electrolyte interphase (SEI) is critical for suppression of lithium dendrites. However, the formation desired SEI by formulating composition very difficult due to complex electrochemical reduction reactions. Here, instead trial-and-error composition, we design Li-11 wt % Sr alloy anode form SrF2-rich in fluorinated electrolytes. Density functional theory (DFT) calculation and experimental characterization demonstrate that has large interfacial energy with Li metal...

A water-in-salt electrolyte (WiSE) offers an electrochemical stability window much wider than typical aqueous electrolytes but still falls short in accommodating high-energy anode materials, mainly because of the enrichment water molecules primary solvation sheath Li+. Herein, we report a new strategy which non-Li cosalt was introduced to alter Li+-solvation structure. The presence asymmetric ammonium salt (Me3EtN·TFSI) increases solubility LiTFSI by two times, pushes salt/water molar ratio...
Metallic lithium is the most competitive anode material for next-generation (Li)-ion batteries. However, one of its major issues Li dendrite growth and detachment, which not only causes safety issues, but also continuously consumes electrolyte Li, leading to low coulombic efficiency (CE) short cycle life metal Herein, metallic suppressed by forming a fluoride (LiF)-enriched solid interphase (SEI) through lithiation surface-fluorinated mesocarbon microbeads (MCMB-F) anodes.

Li-rich layered-oxide cathodes have the highest theoretical energy density among all intercalated cathodes, which attracted intense interests for high-energy Li-ion batteries. However, O3-structured suffer from a low initial Coulombic efficiency (CE), severe voltage fade, and poor cycling stability because of continuous oxygen release, structural rearrangements due to irreversible transition-metal migration, serious side reactions between delithiated cathode electrolyte. Herein, we report...
