Lithium–Sulfur Battery Electrolytes [PDF]
The electrolyte is at the very heart of any battery concept physically, but more and more also mentally amongst battery researchers and developers. This is largely due to the growing insight that many problems related to overall efficiency, life-length ...

Top‐down organic pillaring expands the interlayer spacing of bulk‐sized MoS2 particles while preserving the bulk morphology. Operando X‐ray diffraction and electrochemical dilatometry show that MoS2‐bulk undergoes solvent co‐intercalation in diglyme electrolyte, causing large structural expansion, while pillared, expanded MoS2 suppresses solvent uptake

CuFeS2 is found to induce the formation of intermediate phases, highlighting a strong Cu–Fe synergistic effect during conversion reactions in lithium all‐solid‐state batteries (Li‐SSBs). The integrated reaction pathway effectively suppresses phase separation and accelerates reaction kinetics, leading to enhanced electrochemical reversibility and ...

Electrochemical etching provides an eco‐friendly alternative to hazardous HF methods for MXene production. This approach facilitates the selective isolation of the A‐layer from MAX phases with tunable surface terminations. Controlling voltage, electrolytes, temperature, and duration enables the optimal structural integrity. Nevertheless, existing scale

Wood Cellulosic Membrane With Abundant Nanochannels for Stabilizing Aqueous Zn‐Ion Batteries
A wood‐derived cellulosic membrane separator is developed to suppress dendrite growth in aqueous zinc‐ion batteries. Its aligned nanochannels and hydroxyl‐rich surfaces enable uniform Zn2+ flux, water immobilization, and interfacial stabilization. Zn||Zn cells achieve 1920 h of cycling, Zn||Cu cells maintain 99.5% Coulombic efficiency over 1000 cycles,

Photoassisted Lithium–Sulfur Batteries: Insights from Regulation Mechanisms to Design Strategies
Lithium–sulfur (Li–S) batteries have garnered significant attention owing to high theoretical energy density (2600 Wh kg–1). Their commercialization is otherwise impeded by sluggish redox kinetics and shuttle effect stemming from the generation of ...

All‐solution‐processed, low‐cost extended short‐wavelength infrared photodetectors are realized by coupling colloidal HgTe quantum dots to plasmonic In2O3:Sn,F nanocrystals. Localized surface plasmon resonances boost and spectrally tailor light absorption between 1500 and 3000 nm, enabling responsivities above 40 A W−1.

This study addresses silicon anode degradation using an engineered nSi/Gr/C dual‐carbon matrix. By restricting SEI infiltration, the architecture redirects silicon agglomeration into a beneficial structural self‐adaptive activation. During cycling, silicon nanoparticles self‐organize into a resilient nanoporous sponge. This dynamic network accommodates
