dc.description.abstract“Li-ion battery is the most commonly used storage technology today, which specific capacity is insufficient to supply long-term energy needs such as extended-drive range electric vehicles. To go beyond the capabilities of lithium-ion batteries is a huge challenge, where Li-S batteries have a very promising opportunity. However, there are several problems in rechargeable Li-S batteries that do not allow their practical application so far. Including the intrinsically non conducting nature of sulfur and the structural and morphological changes undergone during the charge-discharge process resulting in unstable chemical and electrical contact. Despite the enormous progress made to improve the electrochemical performance of Lithium cathodes though confined sulfur into carbonaceous matrix, still remains the chal lenge of finding a more appropriate carbon source from a huge variety of precursors still unexplored, which is abundant and inexpensive, with suitable morphology for use in the cathode of Li-S batteries. In this work is reported the electrochemical evaluation of C/S composite materials derived from peanut hulls and corncobs. At a velocity of C/15 the initial capacities are around 800mAhg−1 and after 100 cycles is conserved 73% of the capacity with an average fade per cycle of 0.29% in the case of peanut hull carbón”.es_MX
