“…When loaded with 39 wt % sulfur, S/HPC composites delivered an initial discharge capacity of 1774 mA h g -1 (the excess capacity is attributed to the porous carbon) and remained at 690 mA h g -1 after 50 cycles. M. Klose et al [27] utilized the metal-organic framework (MOF) Basolite F300 as the precursor for porous carbons with hierarchical porosity as a conducting carbon scaffold in Li-S batteries, yielding capacity of up to 550 mA h g -1 after 40 cycles.…”

In order to utilize silicon as alternative anode for unfavorable lithium metal in lithium -sulfur (Li-S) batteries, a profound understanding of the interfacial characteristics in ether-based electrolytes is required. Herein, the solid electrolyte interface (SEI) of a nanostructured silicon/carbon anode after long-term cycling in an ether-based electrolyte for Li-S batteries is investigated. The role of LiNO 3 and 1,3-dioxolane (DOL) in dimethoxy ethane (DME) solutions as typically used electrolyte components on the electrochemical performance and interfacial characteristics on silicon are evaluated. Because of the high surface area of our nanostructured electrode owing to the silicon particle size of around 5 nm and the porous carbon scaffold, the interfacial characteristics dominate the overall electrochemical reversibility opening a detailed analysis. We show that the use of DME/DOL solutions under ambient temperature causes higher degradation of electrolyte components compared to carbonate-based electrolytes used for Li-ion batteries (LIB). This behavior of DME/DOL mixtures is associated with different SEI component formation and it is demonstrated that LiNO 3 addition can significantly stabilize the cycle performance of nanostructured silicon/carbon anodes. A careful postmortem analysis and a discussion in context to carbonate-based electrolyte solutions helps to understand the degradation mechanism of silicon-based anodes in rechargeable lithium-based batteries. Silicon is a highly attractive anode material for rechargeable Liion batteries (LIB) and post LIB systems owing to its high capacity and comparable discharge potential to lithium metal. Considerable progress has been achieved in recent years to tackle the peculiarities of silicon during de-/lithiation.1-2 The enormous volume expansion which causes fracture of individual particles and a low reversibility could be addressed by hierarchically designed nano-sized and amorphous silicon structures.3-6 However, it was shown that among other parameters the electrochemical performance of particularly nanostructured silicon significantly depends on the chosen electrolyte. [7][8][9] This observation is mainly caused by the characteristics of the interfacial layer strongly related to the surface area of the electrode material which is especially high on nanostructures. The interfacial layer, commonly known as solid-electrolyte-interface (SEI), is a surface film typically formed in the initial cycles by decomposition of electrolyte components. Because of the large volume expansion of silicon during lithiation, the SEI likely cracks and is regenerated causing continuous electrolyte consumption and high degradation. In order to reduce degradation and apply silicon as high-performance anode in rechargeable Li-based batteries, a profound knowledge of the interfacial characteristics is necessary. The SEI on silicon is typically studied in carbonate-based electrolytes since silicon is majorly considered as alternative anode for graphite in LIB. [10][11][12][13] Howeve...

Porous carbon is one of the most promising alternatives to traditional graphite materials in lithium-ion batteries. This is not only attributed to its advantages of good safety, stability and electrical conductivity, which are held by all the carbon-based electrodes, but also especially ascribed to its relatively high capacity and excellent cycle stability. Here we report the design and synthesis of a highly porous pure carbon material with multifractal structures. This material is prepared by the vacuum carbonization of a zinc-based metal-organic framework, which demonstrates an ultrahigh lithium storage capacity of 2458 mAh g−1 and a favorable high-rate performance. The associations between the structural features and the lithium storage mechanism are also revealed by small-angle X-ray scattering (SAXS), especially the closed pore effects on lithium-ion storage.
