Tuning the Solvation Structure of a Weakly Solvating Cyclic Ether Electrolyte for Wide‐Temperature Cycling of Lithium‐Sulfurized Polyacrylonitrile Batteries

A weakly solvating single-solvent electrolyte composed of tetrahydropyran stabilizes the lithium-metal anode and sulfurized polyacrylonitrile cathode effectively without the necessity of a fluorinated diluent. It enables stable cycling of Li-SPAN batteries at wide temperature ranges of 0–50 °C. Abstract Sulfurized polyacrylonitrile (SPAN)...

Comprehensive Understanding of Steric‐Hindrance Effect on the Trade‐Off Between Zinc Ions Transfer and Reduction Kinetics to Enable Highly Reversible and Stable Zn Anodes

4-Aminomethyl cyclohexanecarboxylic acid (AMCA) addition with steric hindrance effect is reported to achieve the balance between sluggish mass transfer and rapid electrochemical reduction kinetics via the pull-push interplay for zinc ions. Abstract The electrode interface concentration polarization attributed to the contradiction between...

Homogeneous Complexation Strategy to Manage Bromine for High‐Capacity Zinc–Bromine Flow Battery

Homogeneous complexation is achieved by enhancing the hydrophilicity of the complexation products through the strategy of “polyhydroxy modification” to realize high-capacity (57.2 Ah L−1) and high-stability (100.0% per cycle) zinc–bromine flow battery. Abstract Zinc–bromine flow batteries (ZBFBs) have received widespread attention as a transformative...

Stable LCO Cathodes Charged at 4.6 V for High Energy Secondary Li‐ion Batteries by One‐Pot Dual Metal Fluorides Coating

A cycling performance comparison of LiCoO2 cathodes demonstrates the superior stability and high capacity retention of dual fluoride-coated samples, followed by single fluoride-coated and fluorinated electrolyte-treated samples. The uncoated LiCoO2 with conventional electrolyte shows the lowest performance. The dual coating effectively enhances structural...

Improving Cycling Stability of Ni‐Rich Cathode for Lithium‐Metal Batteries via Interphases Tunning

High-voltage Li-metal batteries often suffer from severe capacity fading due to the degradation of the cathode at high voltages and parasitic reactions between the electrolyte solution and both electrodes. The combination of a morphology-engineered Ni-rich cathode and the formation of a high-quality surface film ensures long-term stability by minimizing...

Interrogating the Role of Stack Pressure in Transport‐Reaction Interaction in the Solid‐State Battery Cathode

This work explores the impact of stack pressure on the electrochemical-transport interaction and performance of solid-state battery (SSB) cathodes. The complex interplay between stack pressure and microstructure-dependent mechanisms critically governs the interfacial resistances, lithiation heterogeneities, and current constriction effects. Optimizing...
