Silicon nanowires (Si NWs) have great promise as an anode material for lithium-ion batteries (LIBs) due to their very high specific capacity. Achieving adequate mass loadings for binder–free Si NWs have been restricted by low surface area, mechanically unstable and poorly conductive current collectors (CC), as well as complicated and expensive fabr...

Potassium-ion batteries (PIBs) have attracted increasing interest as promising alternatives to lithium-ion batteries (LIBs) for application in large-scale electrical energy storage systems (EESSs) owing to a wide earth-abundance, potential price advantages, and low standard redox potential of potassium. Developmental materials for use in PIBs that...

Lithium–sulfur batteries (LSBs) have been regarded as the supreme feasible future generation energy storage system for high‐energy applications due to the exceptional‐specific energy density of 2600 Wh kg−1 and theoretical‐specific capacity of 1675 mAh g−1. Nevertheless, some key challenges which are linked with polysulfide shuttling and sluggish k...

Biomass has been utilized as an energy source for thousands of years typically in the form of wood and charcoal. Technological advances create new methodologies to extract energy and chemicals from biomass. The biomass-derived nanostructured porous carbons (BDNPCs) are the most promising sulfur hosts and interlayers in rechargeable lithium-sulfur (...

Silicon nanowires (Si NWs) have been identified as an excellent candidate material for the replacement of graphite in anodes, allowing for a significant boost in the capacity of lithium‐ion batteries (LIBs). Herein, high‐density Si NWs are grown on a novel 3D interconnected network of binary‐phase Cu‐silicide nanofoam (3D Cux Siy NF) substrate. The...

The potential toxicity and irreversibility of radionuclide Cs place severe pressure on the natural environment, which has become one of the most forefront pollution problems in nuclear energy utilization. To solve this problem, novel self-assembled membranes consisting of two-dimensional (2D) metal-organic frameworks (MOFs) and graphene oxide (GO)...

Coralline-like N-doped hierarchically porous carbon (CNHPC) was prepared via a hydrothermal carbonization process using a sea pollutant enteromorpha as the starting material. The addition of a small amount of glucose during carbonization improved the yield of carbon and the inherent N contents especially for pyrrolic N and pyridinic N atoms. After...

Rechargeable aluminum batteries (RABs) are amongst the most promising of the post-lithium energy storage systems (ESS) with substantially higher specific volumetric capacity (8046 mAh cm−3), higher safety and lower cost. The development of such efficient and low cost ESS is of the essence in order to meet future energy storage demands of modern soc...

World is going to face a serious problem of energy scarcity after 100 years. The present world energy reservoirs will expire in near future. So, it is the need of hour to develop methods and technologies to get remedy of this forth coming energy crisis. The emphasis of these technologies should be on converting waste to energy. The wastes are no do...

I am interested to get standard sulfur cathodes like commercial cathode for LIBs. Is there any supplier where I can get it with different sulfur loading.
Please let me know.
TIA.
Question
When we coated the separator with different kind of materials to block the poly-sulfides, then after cycling we got enough poly-sulfides deposited on the separator. Will the solid deposit onto the separator blocks the pores and slow down the lithium diffusion?
