[PMID: 38763902 DOI: 10.1002/cssc.202400538] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/12/2024] [Revised: 05/14/2024] [Accepted: 05/19/2024] [Indexed: 05/21/2024]
Abstract
Lithium-sulfur batteries (LSBs) have recently gained extensive attention due to their high energy density, low cost, and environmental friendliness. However, serious shuttle effect and uncontrolled growth of lithium dendrites restrict them from further commercial applications. As "the third electrode", functional separators are of equal significance as both anodes and cathodes in LSBs. The challenges mentioned above are effectively addressed with rational design and optimization in separators, thereby enhancing their reversible capacities and cycle stability. The review discusses the status/operation mechanism of functional separators, then primarily focuses on recent research progress in versatile separators with purposeful modifications for LSBs, and summarizes the methods and characteristics of separator modification, including heterojunction engineering, single atoms, quantum dots, and defect engineering. From the perspective of the anodes, distinct methods to inhibit the growth of lithium dendrites by modifying the separator are discussed. Modifying the separators with flame retardant materials or choosing a solid electrolyte is expected to improve the safety of LSBs. Besides, in-situ techniques and theoretical simulation calculations are proposed to advance LSBs. Finally, future challenges and prospects of separator modifications for next-generation LSBs are highlighted. We believe that the review will be enormously essential to the practical development of advanced LSBs.

Abstract
Lithium-sulfur batteries (LSBs) are superior next-generation batteries compared to commercial lithium-ion batteries (LiBs) because of their gravimetric energy densities, which provide longer battery life in a lighter package. However, the biggest hurdle for commercializing LSBs is their poor long-term cycling performance, which stems from polysulfide shuttling. To address this issue, we propose a novel approach: the use of glutamine, an amino acid, as an electrolyte additive to increase the cycling stability. Due to its molecular structure containing amines, the formation of Li dendrites was obstructed by homogenizing the Li-ion flux to shield the exceedingly active Li surfaces with glutamine, thereby reducing the overvoltage during Li plating and stripping. Additionally, the redox reactions of lithium polysulfides were enhanced, which helped to alleviate the shuttling of lithium polysulfides. Therefore, the addition of glutamine improved the stability and reduced the cell degradation rate by approximately 0.066% during high C-rate long-term cycling tests.

Abstract
The ingenious design of high-performance tin-based lithium-ion batteries (LIBs) is challenging due to their poor conductivity and drastic volume change during continuous lithiation/delithiation cycles. Herein, we present a strategy to confine heterostructured SnSe2-SnO2 nanoparticles into macroscopic nitrogen-doped carbon microbelts (SnSe2-SnO2@NC) as anode materials for LIBs. The composites exhibit an excellent specific capacity of 436.3 mA h g-1 even at 20 A g-1 and an ultrastable specific capacity of 632.7 mA h g-1 after 2800 cycles at 5 A g-1. Density Functional Theory (DFT) calculations reveal that metallic SnSe2-SnO2 heterostructures endow the lithium atoms at the interface with high adsorption energy, which promotes the anchoring of Li atoms, and enhances the electrical conductivity of the anode materials. This demonstrates the superior Li+ storage performance of the SnSe2-SnO2@NC microbelts as anode materials.
