Improved Cycle Stability of LiSn Alloy Anode for Different Electrolyte Systems in Lithium Battery

Abstract

Lithium metal anode still confronts a series of problems at the way to commercialization though it has advantages in high energy density. The formation of Li dendrite is the major limitation need to be conquered. Here, a facile and simple LiSn alloy anode prepared by a direct metallurgy method is fabricated and evaluated in both liquid electrolyte and solid electrolyte. Structural analysis and electrochemical measurements reveal the promoted ionic transference of interface and enhanced cycling stability in different electrolyte systems, without dendrite formation. Furthermore, the application of this simple and sustainable LiSn alloy can be extended to more alloy anode and might unlock the next-generation anode in the future.

Synergized Interface Engineering and Alloying Strategy for In Situ Construction of a Three-Dimensional Lithiophilic Carbon Skeleton: Motivating High-Performance Lithium Metal Batteries

“…Finally, the expansive volume change of Li metal during the charging/ discharging processes may lead to electrode pulverization, resulting in a significant decrease in coulombic efficiency and cycling performance. 2 To address these challenges, researchers have devoted substantial efforts to explore new electrolytes, 3 develop solidstate electrolytes, 4 and implement interface modifications. 5 Among these strategies, constructing a three-dimensional (3D) porous collector has proven an effective strategy.…”
