Practical application of lithium-sulfur batteries remains challenging, including issues with both cathode and anode. Recently in Matter, researchers report a novel solution for sulfur cathode and lithium anode, introducing tortuosity into a graphene-oxide host, resulting in significant performance improvement. The use of lithium-sulfur (Li-S) battery as one of the most promising energy storage systems has attracted great interests because of its high theoretical capacity, high abundance, and low cost.1Fan L. Li M. Li X. Xiao W. Chen Z. Lu J. Interlayer Material Selection for Lithium-Sulfur Batteries.Joule. 2019; 3: 361-386Abstract Full Text Full Text PDF Scopus (299) Google Scholar As shown in Figure 1A, a common configuration of Li-S battery is composed of a Li anode, electrolyte, separator, and sulfur cathode. Three major scientific problems in Li-S batteries lead to their poor electrochemical performance:2Pang Q. Liang X. Kwok C.Y. Nazar L.F.

Lithium-sulfur batteries: progress and prospects.Adv. Mater. 2015; 27: 1980-2006Crossref PubMed Scopus (1141) Google Scholar (1) during redox reaction process, the active S and Li2S discharge products are electron- and ion-insulated, along with huge structure variation; (2) the serious shuttle effect of dissolved polysulfide intermediates leads to sulfur loss, low Coulombic efficiency, and side reaction with Li; and (3) the unstable solid-electrolyte interface (SEI) on anode surface causes serious Li loss and dendrite formation especially at high rates. To solve these issues, researchers have developed various efficient strategies to improve electrochemical performances, including the design of sulfur host materials for higher sulfur utilization and preventing shuttling of polysulfides (e.g., functional carbon, metal-organic frameworks, and nanostructured inorganic metal oxides/sulfides), the modification of separators (the modified materials are similar with the above-mentioned host materials), the design of new electrolytes with additives to form stable SEI or low polysulfide solubility, and the protection of Li anode (e.g., artificial SEI).4Pang Q.

Liu X. Zhu K. Wu S. Zhou H. Metal–Organic Framework-based Separator for Lithium–Sulfur Batteries.Nat. Energy. 2016; 1: 16094Crossref Scopus (882) Google Scholar However, these inactive anchor materials lower the cell-level energy density. In the past decade, although great progress in Li-S battery has been made in terms of the electrodes and electrolytes, great challenges still exist in achieving practical applications.7Chen X. Hou T. Persson K.A. Zhang Q. Combining Theory and Experiment in Lithium-Sulfur Batteries: Current Progress and Future Perspectives.Mater. Today. 2019; 22: 142-158Crossref Scopus (238) Google Scholar To follow the principles of commercial Li-ion batteries and realize practical Li-S battery, the electrochemical performances should be evaluated and analyzed under realistic conditions as follows: high cathode loading, low negative to positive electrode capacity ratio, and low electrolyte weight to capacity ratio.8Niu C. Pan H. Xu W. Xiao J. Zhang J.-G. Luo L. et al.Self-Smoothing Anode for Achieving High-Energy Lithium Metal Batteries under Realistic Conditions.Nat. Nanotechnol. 2019; 14: 594-601Crossref PubMed Scopus (348) Google Scholar Considering these important parameters in Li-S battery is of great significance for both fundamental studies and practical applications. In this issue of Matter, Chen et al. report a freestanding one-for-all electrode design by simultaneously engineering the tortuosity and sulfur-affinity of a reduced graphene-oxide (rGO) host for high-performance Li-S batteries (Figure 1B).9Chen H. Zhou G. Boyle D. Wan J. Wang H. Lin D. Mackanic D. Zhang Z. Kim S.C. Lee H.R. et al.Electrode Design with Integration of High Tortuosity and Sulfur-Philicity for High Performance Lithium-Sulfur Battery.Matter. 2020; 2 (this issue): 1605-1620Abstract Full Text Full Text PDF Scopus (61) Google Scholar For the S cathode, this smart architecture not only mitigates the diffusion/dissolution sulfur loss due to the strong bonding from rich oxygen functional groups, but also confines the soluble polysulfide through prolonged diffusion pathways caused by high tortuosity (Figure 1C). For the Li metal anode, this architecture coupling with molten Li can efficiently suppress the formation of Li dendrites. Additionally, the resulting electrodes without binders and carbon additives exhibit fast electronic/ionic diffusion. It is noteworthy that the high-tortuosity and high-affinity architecture was successfully synthesized by milliseconds treating of a freestanding and densely stacked graphene-oxide film at high temperature, demonstrating its facile and efficient synthesis strategy. The heat-triggered ultrafast self-expansion and reduction reaction generates gases and internal pressure between rGO layers, thus resulting in the formation of high-tortuosity rGO with nanogaps. Due to the high sulfur philicity and strong capillary force in nanogaps, sulfur, and lithium can rapidly and uniformly infiltrate into the architecture. To confirm the influences of high tortuosity and high sulfur philicity on Li-S battery performance, another two low-tortuosity and/or low-sulfur-philicity electrodes were designed for comparison. As a proof-of-concept application, the high-tortuosity and high-sulfur-philicity cathode ([email protected]) exhibits higher specific capacity, lower overpotential, superior rate performance, and better cycling stability than other two electrodes. Additionally, through visualizing using a transparent H-cell, the high-tortuosity and high-sulfur-philicity cathode displayed negligible color change in the electrolyte due to very limited polysulfide dissolution/diffusion, indicating the importance of the electrode architecture. Furthermore, to add benefits on its practical applications for Li-S batteries, the cathode was evaluated under high active material loading and at lean electrolyte. At low electrolyte amount of 5∼7 μL mgsulfur−1, this cathode can achieve high areal capacities of 13.7, 15, and 21 mAh cm−2 at high sulfur loadings of 12, 15, and 20 mg cm−2, respectively, with high Coulombic efficiency of over 98%. After cycling, uniformly distributed sulfur species and well-maintained sandwich-like morphology across the electrode demonstrate its successful suppression of polysulfides dissolution/diffusion and sulfur loss. It is well known that the lithium-dendrite-induced short-circuit problem is also a major bottleneck toward safe, long-life Li-S batteries, especially at ultrahigh sulfur loadings. By using the same rGO host, the resulting molten Li-containing composite anode ([email protected]) can efficiently accommodate the “infinite” volume change and decrease the areal current density. Combining the merits on both cathode and anode, the assembled full cell achieved a high energy density of 395 Wh kg−1 at a high cathode mass loading of 22 mg cm−2, low electrolyte amount of 3.5 μL mgsulfur−1, and less Li amount of 13 mg cm−2. It was concluded that a high-tortuosity and high-philicity principle in one-for-all electrodes plays a crucial role and provides a guideline for future efforts in rationally designing electrodes for high-performance Li-S batteries. This work not only solves the major problems of polysulfide diffusion/loss and Li dendrites in Li-S batteries but also presents a state-of-the-art prototype for practical Li-S batteries. Nevertheless, in spite of the breakthrough reported herein on Li-S battery electrodes, future effort is required to achieve high-performance Li-S batteries with lower cost and higher energy density and to replace commercial Li-ion batteries.10Chung S.-H. Manthiram A. Designing Lithium-Sulfur Cells with Practically Necessary Parameters.Joule. 2018; 2: 710-724Abstract Full Text Full Text PDF Scopus (125) Google Scholar The cost of Li-S battery mainly comes from raw materials, electrode fabrication processes, battery assembly process, and electrolytes, all of which deserve considerations. On the other hand, next-generation Li-S battery is promising to reach higher energy density over 500 Wh kg−1 at pouch cell level and meet increasing energy demands. Therefore, although the path toward practical Li-S batteries is tortuous, the vision is not. Electrode Design with Integration of High Tortuosity and Sulfur-Philicity for High-Performance Lithium-Sulfur BatteryChen et al.MatterMay 8, 2020In BriefThe Li-S battery is limited by diffusion loss of soluble polysulfide active materials in cathode and dendrite growth in anode. Here, we demonstrate an integrated concept of high electrode tortuosity and sulfur-philicity for thick sulfur cathode, extending the diffusion loss pathway of polysulfide and bonding with sulfur-based materials to localize the soluble polysulfide within the electrode. Utilizing this integrated design, ultrahigh cathode capacities and cycling stability are achieved. The same graphene host suppresses dendrite growth in Li anode, enabling 278% prolonged cycle life.
