The Role of Metal Disulfide Interlayer in Li–S Batteries
The Journal of Physical Chemistry C, 2017Recently many observations related to the catalytic effects of layered metal disulfide versus polysulfide electrochemistry were documented. In this work, we investigated the reactivity of layered WS2 in a Li-S battery and observed a chemical reaction involving the removal of W ions by polysulfides. The presence of metallic tungsten nanoparticles in the

Negatives for secondary Li-batteries: Li-alloys or metallic Li?
1987Metallic lithium anodes as well as Li-alloy anodes are currently used in commercial rechargeable organic electrolyte batteries. The disadvantage of Li-alloys is of course low energy density and power density compared to metallic lithium; for some applications this disadvantage may be overbalanced by better cycling and storage behaviour of the alloys.
