Thermochemical Core–Shell Architecturing of Si‐SWCNT Composites for High‐Performance Li‐Ion Battery Anodes

Advanced Science, EarlyView.
A thermochemically engineered core–shell Si architecture is developed through the controlled evolution of a SWCNT‐coated Mg2Si precursor. The process simultaneously generates a nanoporous Si shell for strain accommodation and Li+ transport, a chemically anchored SiC interfacial layer for robust mechanical and electrical coupling, and a Mg‐containing Si

Polypyrrole-encapsulated amorphous Bi2S3 hollow sphere for long life sodium ion batteries and lithium-sulfur batteries

, 2019
Sodium ion batteries (SIBs) and lithium–sulfur (Li–S) batteries are considered as the most promising next-generation energy storage devices to displace the widely used lithium ion batteries due to their inherent advantages. Here, polypyrrole-encapsulated

Chelation‐Driven Dual‐Interface Regulation for Long‐Life Aqueous Zn–I2 Batteries

Advanced Science, EarlyView.
Zn2+–TPEN coordination generates TPEN‐derived coordination species (TCC) that contribute to the regulation of both electrode interfaces. At the Zn anode, it creates an interfacial environment with reduced water accessibility that suppresses HER and corrosion while promoting uniform deposition; at the I2 cathode, it captures polyiodide to inhibit ...

Sodium and Sodium-Ion Batteries: 50 Years of Research

, 2018
This paper gives an overview of the research carried out on sodium batteries in the last 50 years. The discovery of the very high Na+ ion conductivity in β-Al2O3 opened the way to high-energy batteries (sodium/sulfur and sodium/NiCl2) for load leveling ...

Potential‐Controlled Ammonium‐Assisted Reversible Electrodeposition of Polyoxometalates for Hybrid Redox Flow Batteries

Advanced Science, EarlyView.
Potential‐controlled NH4+‐assisted reversible electrodeposition of molecular metal oxide clusters enables dynamic solution‐to‐solid electron storage. Leveraging this deposition/dissolution reaction chemistry, polyoxometalate‐based hybrid flow batteries are demonstrated as a new platform for deposition‐based electrochemical energy storage.

Synthetic Shewanella‐Bacillus Microbial Consortia for Enhanced Metal Oxide Leaching From Spent Lithium‐Ion Batteries Using Brewing Wastewater as Leaching Agent

Advanced Science, EarlyView.
A recycling approach of spent lithium‐ion batteries is developed using brewing wastewater as the leaching agent and an engineering microbial consortium as the biocatalyst. Shewanella oneidensis reduces spent LiNixCoyMn1‐x‐yO2 cathodes via extracellular electron transfer, while Bacillus subtilis removes residual ethanol to eliminate inhibition.

Active Oscillations of Elastic Membranes Arising from the Coupling with a Catalytic Reaction

Advanced Science, EarlyView.
Coupling an elastic membrane to a catalytic reaction produces active oscillations that self‐sustain for hours: the membrane cyclically inflates and deflates as the reaction spontaneously activates and deactivates, without external power. Energy release is directly embodied in the oscillation dynamics, opening elasto‐chemical strategies for the physical

In Situ Generation of Gel Foam via Heat‐Accelerated Calcium Ion Release From Nano‐CaCO3 for Lithium‐Ion Battery Fire Suppression and Prevention

Advanced Science, EarlyView.
We present a heat‐accelerated in situ crosslinking strategy to create an alginate gel foam for lithium‐ion battery fire suppression. At ambient temperature, the formulation maintains low viscosity for easy foam generation. After exposure to fire, δ‐gluconolactone hydrolysis accelerates, enabling rapid Ca2+ release from CaCO3 and rapid ionic ...

Tailoring Electronic Structure of NbB2 Nanorods Through Selenium Incorporation for Synergistically Enhanced Hydrogen Evolution and Triboelectric Energy Harvesting

Advanced Science, EarlyView.
Selenium incorporation modulates the electronic structure of niobium diboride (Se‐NbB2) nanorods, enhancing the active site density and resulting in superior hydrogen evolution performance for sustainable energy applications. ABSTRACT The sluggish hydrogen evolution reaction (HER) kinetics of non‐noble‐metal catalysts remain a major challenge for ...
