Strategies to Suppress Polysulfide Dissolution and Its Effects on Lithium–Sulfur Batteries

Batteries, Journal Year: 2025, Volume and Issue: 11(4), P. 139 - 139

Published: April 3, 2025

Lithium–sulfur batteries (LSBs), with a high energy density (2600 Wh kg−1) and theoretical specific capacity (1672 mA h g−1), are considered the most promising next-generation rechargeable storage devices. However, polysulfide dissolution shuttle effect cause severe fading rapid loss of active material; hence, these must be addressed first. This review provides an overview various strategies employed to immobilise polysulfides via trapping physical chemical adsorption using porous cathode designs, heterostructures, functionalised separators, polymer binders. The working mechanism each strategy is reviewed discussed, highlighting their advantages disadvantages, they analysed through comparisons battery performance limitations in terms practical applications. Finally, future prospects for design synthesis LSBs limit discussed.

Inorganics, Journal Year: 2024, Volume and Issue: 12(12), P. 302 - 302

Published: Nov. 25, 2024

Potassium-ion batteries (PIBs) are regarded as a potential substitute for LIBs owing to the benefits of potassium’s abundance, low cost, and high safety. Nonetheless, practical implementation potassium-ion still encounters numerous challenges, with selection design anode materials standing out key factor impeding their progress. Hard carbon, characterized by its amorphous structure, specific surface area, well-developed pore facilitates insertion/extraction potassium ions, demonstrating excellent rate performance cycling stability. This review synthesizes recent advancements in hard carbon utilized PIB anodes, particular focus on storage mechanism, electrochemical properties, modification strategies carbon. Ultimately, we present summary current challenges future development directions materials, objective providing reference optimization PIBs.
