High-voltage lithium-ion batteries (LIBs) enabled by high-voltage electrolytes can effectively boost energy density and power density, which are critical requirements to achieve long travel distances, fast-charging, reliable safety performance for electric vehicles. However, operating these beyond the typical conditions of LIBs (4.3 V vs Li/Li+ ) leads severe electrolyte decomposition, while interfacial side reactions remain elusive. These issues have become a bottleneck developing...
Electrolytes play a critical role in controlling metal-ion battery performance. However, the molecular behavior of electrolyte components and their effects on electrodes are not fully understood. Herein, we present new insight most commonly used ethylene carbonate (EC) cosolvent both with bulk at electrolyte-electrode interface. We have discovered phenomenon that contributes to stabilizing electrolyte, besides well-known roles dissociating metal salt forming solid interphase (SEI). As...
Abstract Electrolyte design has become ever more important to enhance the performance of lithium‐ion batteries (LIBs). However, flammability issue and high reactivity conventional electrolytes remain a major problem, especially when LIBs are operated at voltage extreme temperatures. Herein, we novel non‐flammable fluorinated ester electrolyte that enables cycling stability in wide‐temperature variations (e.g., −50 °C–60 °C) superior power capability (fast charge rates up 5.0 C) for...
Abstract High‐voltage lithium metal batteries are the most promising energy storage technology due to their excellent density (>400 Wh kg −1 ). However, oxidation decomposition of conventional carbonate‐based electrolytes at high‐potential cathode, detrimental reaction between anode and electrolyte, particularly uncontrolled dendrite growth, always lead a severe capacity decay and/or flammable safety issues, hindering practical applications. Herein, solvation structure engineering...
Lithium–sulfur (Li–S) batteries have attracted great attention in the past two decades, because of their high theoretical energy density 2600 Wh kg–1 and cost-effective sulfur cathode. However, it is still far from commercialization, unlike that lithium-ion batteries. Although numerous research has been presented on cathode, lithium metal anode, separator modification, intercalated layer within cell configuration, electrolyte design, problematic issues polysulfide shuttling effect cannot be...
Potassium-ion batteries (KIBs) are attractive alternatives to lithium-ion (LIBs) because of their lower cost and global potassium sustainability. However, designing compatible electrolytes with graphite anode remains challenging. This is the electrolyte decomposition and/or exfoliation (due K+–solvent co-insertion) always exist, which much harder overcome compared case LIBs higher activities K+. Herein, we report a general principle design anode, where K+ can be reversibly (de)intercalated....
Engineering the solid electrolyte interphase (SEI) that forms on electrode is crucial for achieving high performance in metal-ion batteries.

Herein, a new strategy switching to tune properties presented, by which unique and thinner can be pre-formed graphite first an ether-based electrolyte, then as-designed demonstrate extremely high-rate capabilities carbonate-based enabling design...
Exploring new routes to lock the dynamic C=N bonds in imine-linked covalent organic frameworks (COFs) is highly desired for enhancing their stability and functionality. Herein, a novel bridge locking strategy via rhodium-catalyzed [4+2] annulation developed construct nonsubstituted quinoline-linked COFs (NQ-COFs). The notable feature of this includes high conversion efficiency, oxidant-free, generality synthesis variety NQ-COFs with chemical stability. Particularly, after post-synthetic...
Abstract Benzoxazole‐linked covalent organic frameworks (BO−COFs), despite their exceptional chemical stability, are still in infancy. This is primarily because the current prevalent methods require use of special ortho ‐hydroxyl‐substituted aromatic amines as monomers. Herein, we report an innovative strategy to access BO−COFs directly from imine‐linked COFs (Im−COFs) without pre‐embedded OH groups, using a two‐step sequential oxidation/cyclization process. The process included oxidation...
We developed a multilevel lithography process to fabricate graphene p-n-p junctions with contactless, suspended top gates. This fabrication procedure minimizes damage or doping the single atomic layer, which is only exposed conventional resists and developers. The does not require special equipment for depositing gate dielectrics releasing sacrificial layers, compatible annealing procedures that improve device mobility. Using this technique, we devices local gates, where creation of high...
