Mastering Surface Sulfidation of MnP‐MnO₂ Heterostructure to Facilitate Efficient Polysulfide Conversion in Li─S Batteries

Advanced Science, Journal Year: 2024, Volume and Issue: 11(32)

Published: June 24, 2024

Abstract The development of lithium–sulfur (Li─S) batteries has been hampered by the shuttling effect lithium polysulfides (LiPSs). An effective method to address this issue is use an electrocatalyst accelerate catalytic conversion LiPSs. In study, heterogeneous MnP‐MnO 2 nanoparticles are uniformly synthesized and embedded in porous carbon (MnP‐MnO /C) as core catalysts improve reaction kinetics situ characterization density functional theory (DFT) calculations confirm that heterostructure undergo surface sulfidation during charge/discharge process, forming MnS phase. Surface catalyst significantly accelerated SRR Li S activation, effectively inhibiting LiPSs effect. Consequently, /C@S cathode achieves outstanding rate performance (10 C, 500 mAh g −1 ) ultrahigh cycling stability (0.017% decay per cycle for 2000 cycles at 5 C). A pouch cell with delivers a high energy 429 Wh kg . This study may provide new approach investigating electrocatalysts, which valuable advancing high‐energy‐density Li−S batteries.

Optimizing Electron Modulation Induced by the Interfacial Coupling in Cu₃P‐Cu₂O Heterostructures to Enhance Polysulfide Conversion

Advanced Functional Materials, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 11, 2025

Abstract Electrocatalysts can inhibit the shuttling of lithium polysulfides (LiPSs) in Li–S batteries by enabling catalytic conversion LiPSs. In this research, heterogeneous Cu 3 P‐Cu 2 O nanoparticles anchored on porous carbon network (Cu O/PC) are investigated to stimulate reaction kinetics LiPSs conversion. At heterojunction interface, high electron density measured functional theory energizes transfer, anchoring The strong interfacial coupling effect generated heterostructure endows active sites with promoted adsorption capability. improved sulfur reduction and Li S activation suppress shuttling. Remarkably, cells equipped O/PC@S cathode marked capacity 1254.3 mAh g −1 at 0.2C ultrahigh cycling stability (0.021% decay rate per cycle after 1200 cycles 4C). Considering practical applications, cathode‐based pouch cell exhibited an initial specific 1069.5 a energy 378.8 Wh kg . This work established pathway for regulating through copper‐based catalysts, exhorting design highly efficient catalysts batteries.

Recent Progress and Prospects on Sodium-Ion Battery and All-Solid-State Sodium Battery: A Promising Choice of Future Batteries for Energy Storage

Energy & Fuels, Journal Year: 2024, Volume and Issue: 38(11), P. 9280 - 9319

Published: May 13, 2024

At present, in response to the call of green and renewable energy industry, electrical storage systems have been vigorously developed supported. Electrochemical are mostly comprised batteries, which outstanding advantages such as high density conversion efficiency. Among them, secondary batteries like lithium sodium lead-acid received wide attention recent years. Lithium-ion (LIBs) existed for a long time. However, due limited resources worldwide, uneven distribution, worrying safety issues, development LIBs has gradually hindered. Meanwhile, sodium-ion (SIBs), whose working principle is similar that LIBs, emphasized by researchers abundant low cost. Moreover, all-solid-state (ASSBs), higher density, simpler structure, stability safety, also under rapid development. Thus, SIBs ASSBs both expected play important roles applications. This Review focuses mainly on detailed introduction constituent materials ASSBs, analyzing cathode anode solid-state electrolytes (SSEs) past five The direction each SSE suitable listed remarked, nonactive separators collectors briefly mentioned. Finally, reasonable assessment prospects different preparation methods put forward.
