Progresses and Prospects of Asymmetrically Coordinated Single Atom Catalysts for Lithium−Sulfur Batteries

Energy & environment materials, Journal Year: 2024, Volume and Issue: 7(4)

Published: Feb. 11, 2024

Lithium–sulfur batteries (LSBs) are widely regarded as promising next‐generation due to their high theoretical specific capacity and low material cost. However, the practical applications of LSBs limited by shuttle effect lithium polysulfides (LiPSs), electronic insulation charge discharge products, slow LiPSs conversion reaction kinetics. Accordingly, introduction catalysts into is one effective strategy solve issues sluggished LiPS conversion. Because nearly 100% atom utilization electrocatalytic activity, single‐atom (SACs) have been used mediators for LSBs' reactions. Excitingly, SACs with asymmetric coordination structures exhibited intriguing superior catalytic activities when compared traditional M–N 4 active sites. In this review, we systematically describe recent advancements in installation asymmetrically coordinated structure reactions LSBs, including nitrogen SACs, heteroatom support bimetallic SACs. Particularly noteworthy discussion mechanism spanning Finally, a perspective on future developments LSB provided.

Lithium-Ion Conductor Li₂ZrO₃-Coated Primary Particles To Optimize the Performance of Li-Rich Mn-Based Cathode Materials

ACS Applied Materials & Interfaces, Journal Year: 2023, Volume and Issue: 15(30), P. 36394 - 36403

Published: July 21, 2023

A lithium-rich manganese-based cathode material (LRMC) is currently considered as one of the most promising next-generation materials for lithium-ion batteries, which has received much attention, but LRMC still faces some key scientific issues to break through, such poor rate capacity, rapid voltage, capacity decay, and low first coulomb efficiency. In this work, homogeneous Li2ZrO3 (LZO) was successfully coated on surface Li1.2Mn0.54Ni0.13Co0.13O2 (LRO) by molten salt-assisted sintering technology. good chemical electrochemical stability, can effectively inhibit side reaction between electrode electrolytes reduce dissolution transition metal ions. Thus, as-prepared LRO@LZO composites are expected improve cycling performance. It be found that discharge specific LRO 271 mAh g–1 at 0.1 C, retention 93.7% after 100 cycles 1 C. addition, an excellent conductor, prone increasing transfer improving LRO. Therefore, study provides a new solution structure stability performance LRMCs.
