An Exploratory Study of MoS2 as Anode Material for Potassium Batteries

Potassium-based batteries represent one of the emerging classes post-lithium electrochemical energy storage systems in international scene, due to both abundance raw materials and achievable cell potentials not far from those lithium batteries. In this context, it is important define electrodes electrolytes that give reproducible performance can be used by different research groups as an internal standard when developing new materials. We propose molybdenum disulfide (MoS2) a valid anode choice, being commercial easily processable material, 2D layered structure which promising for large potassium ions reversible storage. It has been proven work hundreds cycles, keeping constant specific capacity around 100 mAh g?1 while also preserving its interphase morphology.
