Nitrogen-doped carbon nanofiber webs (CNFWs) with high surface areas are successfully prepared by carbonization-activation of polypyrrole KOH. The as-obtained CNFWs exhibit a superhigh reversible capacity 943 mAh g−1 at current density 2 A even after 600 cycles, which is ascribed to the novel porous nanostructure and high-level nitrogen doping.
For lithium–sulfur batteries, commercial application is hindered by the insulating nature of sulfur and dissolution reaction intermediates polysulfides. Here, we present an ordered meso-microporous core–shell carbon (MMCS) as a container, which combines advantages both mesoporous microporous carbon. With large pore volume highly porous structure, "core" promises sufficient loading high utilization active material, while "shell" containing smaller acts physical barrier stabilizes cycle...

Abstract not Available.
All-solid-state batteries are promising candidates for the next-generation safer batteries. However, a number of obstacles have limited practical application all-solid-state Li (ASSLBs), such as moderate ionic conductivity at room temperature. Here, unlike most previous approaches, superior performances ASSLBs achieved by greatly reducing thickness solid-state electrolyte (SSE), where is no longer limiting factor. The ultrathin SSE (7.5 µm) developed integrating low-cost polyethylene...
Sulfurized polyacrylonitrile is suggested to contain Sn (n ≤ 4) and shows good electrochemical performance in carbonate electrolytes for lithium sulfur batteries. However inferior results ether suggest that high solubility of Li2Sn trumps the limited redox conversion, leading dissolution shuttling. Here, we introduce a small amount selenium sulfurized accelerate delivering excellent both electrolytes, including reversible capacity (1300 mA h g-1 at 0.2 A g-1), 84% active material utilization...
A simple and cost-effective morphogenetic route has been developed for the fabrication of a hierarchically nanostructured "cellulose" MoO2 monolith in large qualities, whereby cotton texture acts as both template stabilizer.

Our single-component lithium-storage devices also...
Abstract Uncontrolled growth of Zn dendrites is the main reason for short‐circuit failure aqueous Zn‐ion batteries. Using electrolyte additives to manipulate crystal one most convenient strategies mitigate dendrite issue. However, would be unstable during cycling due structural reconstruction deposition layer. Herein, it proposed use 1‐butyl‐3‐methylimidazolium cation (BMIm + ion) as an additive, which could steadily induce preferential (002) plane and inhibit formation dendrites....

Abstract Solid–solid reactions are very effective for solving the main challenges of lithium–sulfur (Li–S) batteries, such as shuttle effect polysulfides and high dependence electrolyte consumption. However, low sulfur content sluggish redox kinetics cathodes dramatically limit practical energy density Li–S batteries. Here a rationally designed hierarchical cathode to simultaneously solve above‐mentioned is reported. With nanoscale core, selenium‐doped sulfurized polyacrylonitrile (PAN/S 7...

Abstract The sluggish conversion kinetics and shuttling behavior of lithium polysulfides (LiPSs) seriously deteriorate the practical application lithium–sulfur (Li–S) batteries. Herein, Ni single atoms on hollow carbon nanosheet‐assembled flowers (Ni‐NC) are synthesized via a facile pyrolysis‐adsorption process to address these challenges. as‐designed Ni‐NC with enhanced mesoporosity accessible surface area can expose more catalytic sites facilitate electron/ion transfer. These advantages...
Abstract The growth of lithium dendrites hinders the commercial applications lithium‐metal batteries. Electrolytes play a crucial role in influencing electrode/electrolyte interfacial chemistry. Traditional electrolytes adopt strongly solvating solvents to dissolve Li salts, creating an organic‐rich solid electrolyte interface (SEI). + conductivity and mechanical strength SEI are poor, so derived cannot effectively suppress dendrites. weakly (WSE) system can realize inorganic‐rich SEI,...
Sodium-ion batteries are competitive candidates for large-scale energy storage due to the abundant sodium resource. However, electrode interface in conventional electrolyte is unstable, deteriorating cycle life of cells. Introducing functional additives can generate stable interfaces.
