Abstract

We report that electrochemical performances of lithium-sulfur batteries have received much progress in recent years. However, their practical deployment encounters challenges with respect to optimizing the cell-fabrication parameters (e.g., amounts of the active material and electrolyte). We present here an “ant-nest-like” cathode substrate with unique architecture to synchronously attain high electrochemical performance and necessary cell-fabrication parameters. The cells with a high sulfur loading (11.5 mg cm^-2), a high sulfur content (75 wt.%), and a low electrolyte/sulfur ratio (9 μL mg^-1) display a high areal capacity and energy density of, respectively, 7 mA h cm^-2 and 14 mW h cm^-2 with a capacity retention of 70% after 150 cycles. Moreover, the cells exhibit a low self-discharge behavior with a low self-discharge constant of 0.0013 per day and a long rest period of one month. Lastly, these dynamic and static electrochemical stabilities are attributed to the ant-nest-like structure and low surface area of the cathode substrate that allows, respectively, the accommodation and encapsulation of a high amount of active material and reduces the consumption of electrolyte.

A core–shell cathode substrate for developing high-loading, high-performance lithium–sulfur batteries

Journal Article Yu, Ran ; Chung, Sheng-Heng ; Chen, Chun-Hua ; ... - Journal of Materials Chemistry. A

Lithium–sulfur batteries with a high theoretical energy density would be a promising next-generation energy-storage system if their cell-fabrication parameters (e.g., sulfur loading/content and the electrolyte/sulfur ratio) are improved to a practically necessary level. In this article, we report the design of a three-dimensional core–shell carbon substrate, integrating a porous internal core with a conductive external carbon nanofiber shell. Such a carbon substrate encapsulates a high amount of sulfur as the active material core to form a high-loading core–shell cathode, attaining an ultra-high sulfur loading and content of, respectively, 23 mg cm^-2 and 75 wt%. With distinguishable internal and external regions,more »« less

TiS₂–Polysulfide Hybrid Cathode with High Sulfur Loading and Low Electrolyte Consumption for Lithium–Sulfur Batteries

Journal Article Chung, Sheng -Heng ; Luo, Liu ; Manthiram, Arumugam - ACS Energy Letters

Sulfur cathodes have a high theoretical capacity of 1675 mAh g^–1, making the lithium–sulfur batteries a promising technology for future energy-storage devices. However, their commercial viability is faced with challenges arising from intrinsic electrochemical instabilities and inappropriate cell fabrication parameters. We report here the feasibility of employing TiS₂ as a conductive polysulfide adsorbent, which allows the use of a high amount of electrochemically active polysulfides in building a TiS₂–polysulfide hybrid cathode. The hybrid cathode exhibits long cycle stability at a C/5 rate over 200 cycles with a high areal capacity and energy density of, respectively, 10 mAh cm^–2 and 20more »« less

A Facile, Low-Cost Hot-Pressing Process for Fabricating Lithium-Sulfur Cells with Stable Dynamic and Static Electrochemistry

Journal Article Chung, Sheng -Heng ; Lai, Ke -Yu ; Manthiram, Arumugam - Advanced Materials

Abstract Lithium–sulfur batteries are among the most promising low‐cost, high‐energy‐density storage devices. However, the inability to host a sufficient amount of sulfur in the cathode while maintaining good electrochemical stability under a lean electrolyte condition has limited the progress. The main cause of these challenges is the sensitivity of the sulfur cathode to the cell‐design parameters (i.e., the amount of sulfur and electrolyte) and the experimental testing conditions (i.e., cycling rates and analysis duration). Here, a hot‐pressing method is presented that effectively encapsulates a high amount of sulfur in the cathode within only 5 s, resulting in high sulfur loadingmore »« less

Designing Lithium–Sulfur Batteries with High-Loading Cathodes at a Lean Electrolyte Condition

Journal Article Chung, Sheng -Heng ; Manthiram, Arumugam - ACS Applied Materials and Interfaces

Developing lithium–sulfur cells with a high-loading cathode at a lean-electrolyte condition is the key to bringing the lithium–sulfur technology into the energy-storage market. However, it has proven to be extremely challenging to develop a cell that simultaneously satisfies the abovementioned metrics while also displaying high electrochemical efficiency and stability. Here, we present a concept of constructing a conductive cathode substrate with a low surface area and optimized nanoporosity (i.e., limited micropores in the porous matrix) that enables achieving a high sulfur loading of 13 mg cm^–2 and a high sulfur content of 75 wt % with an extremely low electrolyte/sulfurmore »« less

Molybdenum Boride as an Efficient Catalyst for Polysulfide Redox to Enable High‐Energy‐Density Lithium–Sulfur Batteries

Journal Article He, Jiarui ; Bhargav, Amruth ; Manthiram, Arumugam - Advanced Materials

Abstract Lithium–sulfur (Li–S) batteries, despite having high theoretical specific energy, possess many practical challenges, including lithium polysulfide (LiPS) shuttling. To address the issues, here, hydrophilic molybdenum boride (MoB) nanoparticles are presented as an efficient catalytic additive for sulfur cathodes. The high conductivity and rich catalytically active sites of MoB nanoparticles allow for a fast kinetics of LiPS redox in high‐sulfur‐loading electrodes (6.1 mg cm ⁻² ). Besides, the hydrophilic properties and good wettability toward electrolyte of MoB can facilitate electrolyte penetration and LiPS redox, guaranteeing a high utilization of sulfur under a lean‐electrolyte condition. Therefore, the cells with MoB achievemore »« less
