“…For instance, only in the first plateau, a very high self-discharge rate is observed because of the shuttle effect [4,6]. In the second voltage plateau, Li 2 S is precipitated [5]. Only Li 2 S is precipitated as a solid product in LiS cells, as published in [7].…”

“…These DOD levels are all located in the lower plateau with respect to voltage limits of this investigation. Different lithium polysulfides Li 2 S n 1 ≤ n ≤ 8 exist in the second plateau [5]. The highest recovered capacity is expected at the highest DOD level because of the increasing concentration of precipitated Li 2 S during the discharge process in the second plateau.…”

Lithium sulfur batteries have a promisingly high theoretical specific energy density of about 2600 Wh/kg and an expected practical specific energy density of about 500-600 Wh/kg. Therefore, it is a highly promising future energy storage technology for electric vehicles. Beside these advantages, this technology shows a low cell capacity at high discharge currents. Due to the capacity recovery effect, up to 20% of the total cell capacity becomes available again with some rest time. This study shows a newly-developed capacity recovery model for lithium sulfur batteries. Due to the long rest periods of electric vehicles, this effect has an important influence on the usable cell capacity and depth of discharge in lithium sulfur batteries.

The modular assembly of microstructures from simple nanoparticles offers a powerful strategy for creating materials with new functionalities. Such microstructures have unique physicochemical properties originating from confinement effects. Here, the modular assembly of scattered ketjen black nanoparticles into an oval-like microstructure via double "Fischer esterification," which is a form of surface engineering used to fine-tune the materials surface characteristics, is presented. After carbonization, the oval-like carbon microstructure shows promise as a candidate sulfur host for the fabrication of thick sulfur electrodes. Indeed, a specific discharge capacity of 8.417 mAh cm at 0.1 C with a high sulfur loading of 8.9 mg cm is obtained. The large-scale production of advanced lithium-sulfur battery pouch cells with an energy density of 460.08 Wh kg @18.6 Ah is also reported. This work provides a radically different approach for tuning the performance of a variety of surfaces for energy storage materials and biological applications by reconfiguring nanoparticles into desired structures.

Rechargeable lithium–sulfur batteries (LSBs) are recognized as a promising candidate for next‐generation energy storage devices because of their high theoretical specific capacity and energy density. However, the insulating of sulfur, Li2S2/Li2S, and the shuttling effect of high order lithium polysulfides (LiPSs) hinder its practical applications. Herein, a heterostructure is explored to enhance the conversion reaction kinetics and adsorption ability of LiPSs. By rationally designing a conductive carbon framework and polar metal sites, both experimental and theoretical results show strong adsorption abilities for dissolved LiPSs and promote the conversion reaction rate. A CoSe2/Co3O4@NC‐CNT/S cathode shows an excellent rate performance (≈1457 mAh g−1 at 0.1 C and still retains ≈688 mAh g−1 at a high rate of 5 C). When performing charge–discharge in long‐term stability at 2 C, the CoSe2/Co3O4@NC‐CNT/S cathode delivers a high initial specific capacity of ≈780 mAh g−1 and retains ≈602 mAh g−1 after 500 cycles with an excellent Coulombic efficiency of ≈95.4%. Remarkably, the battery can entirely operate even at a very high sulfur loading of ≈10.1 mg cm−2 and lean electrolyte condition. This work emphasizes a new strategy to rationally design heterostructures that can encourage the industrial application of LSBs.
