Special Issue Information

Dear Colleagues,

Elemental sulfur, with its high theoretical capacity (1675 mAh g−1) and low cost, is among the most promising cathode materials for next-generation battery technologies for use in electric vehicles and stationary energy storage. However, the issue of polysulfide dissolution significantly limits both the energy density and cycle life of metal-sulfur batteries (e.g., Li–S and Na–S batteries). Novel strategies are urgently needed to tackle this challenge. Additionally, the use of all-solid-state metal–sulfur batteries, which eliminate polysulfide dissolution, has recently gained attention as a promising solution. Despite this, the degradation mechanisms—particularly the mechanochemical evolution within the cell—remain poorly understood.

In this Special Issue, we are looking for contributions that

  • Develop conductive hosts to mediate polysulfide dissolution and migration;
  • Synthesize polymeric sulfur active materials with restricted polysulfide dissolution;
  • Promote conversion reaction kinetics using electrocatalysts or electrolyte additives;
  • Fabricate metal–sulfur cells with high mass loading and a low electrolyte-to-sulfur ratio;
  • Develop new liquid/semi-solid/solid-state electrolytes to restrict or fundamentally prevent polysulfide dissolution;
  • Understand the mechanical or chemical evolution of all-solid-state metal–sulfur batteries;
  • Study degradation mechanisms by simulating the evolution of cells or cell components.

Topics of interest include, but are not limited to, the following:

  • Advanced conductive hosts;
  • Structured electrodes;
  • Electrocatalysis of sulfur conversion reactions;
  • Liquid/semi-solid/solid-state electrolyte engineering;
  • Mechanochemical evolutions;
  • Degradation mechanisms.

This paper examines the problem of modeling lithium–sulfur (Li-S) battery discharge dynamics. The importance of this problem stems from the attractive specific energy levels achievable by Li-S batteries, which can be particularly appealing for applications such as aviation electrification. Previous research presents different Li-S battery models, including “zero-dimensional” models that neglect diffusion while using the laws of electrochemistry to represent reduction–oxidation (redox) rates. Zero-dimensional models typically succeed in capturing key features of Li-S battery discharge, including the high plateau, low plateau, and dip point visible in the discharge curves of certain Li-S battery chemistries. However, these models’ use of one state variable to represent the mass of each active species tends to furnish high-order models, with many state variables. This increases the computational complexity of model-based estimation and optimal control. The main contribution of this paper is to develop low-order state-space model of Li-S battery discharge. Specifically, the paper starts with a seventh-order zero-dimensional model of Li-S discharge dynamics, analyzes its discharge behavior, constructs phenomenological second- and third-order models capable of replicating this behavior, and parameterizes these models. The proposed models succeed in capturing battery discharge behavior accurately over a wide range of discharge rates. To the best of our knowledge, these are two of the simplest published models capable of doing so. Full article

Room-temperature sodium–sulfur (RT Na–S) batteries offer a superior, high-energy-density solution for rechargeable batteries using earth-abundant materials.

Room-temperature sodium–sulfur (RT Na–S) batteries offer a superior, high-energy-density solution for rechargeable batteries using earth-abundant materials. However, conventional RT Na–S batteries typically use sulfur as the cathode, which suffers from severe volume expansion and requires pairing with a sodium metal anode, raising significant safety concerns. Utilizing Na2S as the cathode material addresses these issues, yet challenges such as Na2S’s low conductivity as well as the shuttle effect of polysulfide still hinder RT Na–S battery development. Herein, we present a simple and cost-effective method to fabricate a Na2S–Na6CoS4/Co@C cathode, wherein Na2S nanoparticles are embedded in a conductive carbon matrix and coupled with dual catalysts, Na6CoS4 and Co, generated via the in situ carbothermal reduction of Na2SO4 and CoSO4. This approach creates a three-dimensional porous composite cathode structure that facilitates electrolyte infiltration and forms a continuous conductive network for efficient electron transport. The in situ formed Na6CoS4/Co electrocatalysts, tightly integrated with Na2S, exhibit strong catalytic activity and robust physicochemical stabilization, thereby accelerating redox kinetics and mitigating the polysulfide shuttle effect. As a result, the Na2S–Na6CoS4/Co@C cathode achieves superior capacity retention, demonstrating a discharge capacity of 346 mAh g−1 after 100 cycles. This work highlights an effective strategy for enhancing Na2S cathodes with embedded catalysts, leading to enhanced reaction kinetics and superior cycling stability. Full article

Lithium–sulfur batteries (LSBs) are widely studied as an alternative to lithium-ion batteries, this emphasis being due to their high theoretical energy density and low cost, and to the high natural abundance of sulfur. Lithium polysulfide shuttling and lithium dendrite growth have limited their commercialization. Porous polyvinylidene fluoride (PVDF) separators have shown improved performance (relative to hydrocarbon separators) in lithium-ion batteries due to faster lithium-ion migration and higher Li+ transference number. A thin polar PVDF membrane has now been fabricated via phase inversion (an immersion-precipitation method) yielding a β (polar) phase concentration of 72%. Preparation from commercial PVDF used dimethylformamide (DMF) solvent at the optimized crystallizing temperature of 70 °C, and pores in the membrane were generated by exchange of DMF with deionized water as non-solvent. The polar PVDF film produced has the advantages of being ultrathin (15 µm), lightweight (1.15 mg cm−2), of high porosity (75%) and high wettability (84%), and it shows enhanced thermal stability relative to polypropylene (PP). The porous, polar PVDF membrane was combined with a commercially available PP membrane to give a hybrid, two-layer, separator combination for LSBs. A synergy was created in the two-layer separator, providing high sulfur utilization and curbing polysulfide shuttling. The electrochemical performance with the hybrid separator (PP–β-PVDF) was evaluated in LSB cells and showed good cyclability and rate capability: those LSB cells showed a stable capacity of 750 mA h g−1 after 100 cycles at 0.1 C, much higher than that for otherwise-identical cells using a commercial PP-only separator (480 mA h g−1).

Lithium–sulfur batteries (LSBs) are considered candidates for next-generation energy storage systems due to their high theoretical energy density and low cost. However, their practical applications are constrained by the shuttle effect, lithium dendrites, low conductivity, and volume expansion of sulfur. Metal–organic frameworks (MOFs) have emerged as promising materials for addressing these challenges, owing to their exceptional adsorption and catalysis capabilities, coupled with a readily adjustable form-factor design. This review provides a broader perspective by comprehensively examining the applications of MOFs in LSBs, covering their roles in cathodes, separators, and electrolytes from multiple dimensions, including their reaction mechanisms, the development potential of MOFs as cathode materials, and the positive impacts on LSBs’ performance achieved through the preparation of MOFs and modifications of intermediate, separator, and electrolyte. Finally, we provide perspectives on future development directions in this field. Full article
