Foldable and High Sulfur Loading 3D Carbon Electrode for High-performance Li-S Battery Application
Sulfur is a promising cathode material with a high theoretical capacity of 1672 mAh g-1, however, the practical energy density of Li-S battery is far away from such promising due to its low active material utilization and low sulfur loading. Moreover, the challenges of the low electrical conductivity of sulfur and the high solubility of polysulfide intermediates still hinder its practical appli...

متن کاملCopper-Stabilized Sulfur-Microporous Carbon Cathodes for Li–S Batteries
wileyonlinelibrary.com interact with two Li atoms per S atom, the S cathode can provide reversible high capacity of 1675 mAh g -1 at average potentials of 2.0 V, [ 1–3 ] which is 10× higher energy density than that of classical commercial LiCoO 2 cathode. Since the capacity of current LiCoO 2 -graphite Li-ion battery is controlled by LiCoO 2 cathode, replacement of expensive LiCoO 2 with cheap ...
متن کاملExploring 3D microstructural evolution in Li-Sulfur battery electrodes using in-situ X-ray tomography
Lithium sulfur (Li-S) batteries offer higher theoretical specific capacity, lower cost and enhanced safety compared to current Li-ion battery technology. However, the multiple reactions and phase changes in the sulfur conversion cathode result in highly complex phenomena that significantly impact cycling life. For the first time to the authors' knowledge, a multi-scale 3D in-situ tomography app...
