Synthesis and Electrochemical Properties of TiO₂-Ti₃C₂ Quantum Dots with a Layered Structure as Efficient Sulfur Hosts for High-Performance Lithium-Sulfur Batteries

Joo-Hyun Kim, B.S. Reddy, Youna Choi, Ho-Jun Na et autres

Purpose: An ideal sulfur-supporting material for lithium-sulfur (Li-S) batteries would exhibit both minimal volume expansion and high electrical conductivity because these properties are essential for improving cycling stability, and enable implementation in large-scale applications. BR/Methods: In this work, we developed TiO₂ quantum …

Development and Evaluation of Sn Foil Anode for Sodium‐Ion Batteries

Changhyeon Kim, Hui-Hun Kim, Milan K. Sadan, Minyeong Jeon et autres

Abstract Metal foil electrodes are simple to prepare and have a high active material loading, making them well suited for the fabrication of inexpensive high‐energy‐density batteries. Herein, Sn metal foil is used as a binder‐ and conductive additive‐free anode for sodium‐ion batteries, …
