Rechargeable lithium batteries have become of primary importance due to their technological applications in portable electronic devices, and appear as the most promising alternative for transport based on sustainable electricity. Currently, the market of rechargeable batteries is primarily based on Li-ion batteries, whose production is continually increasing. However, to extend their applicability to other fields, their energy and power density must be improved. In this sense, the understanding of the processes by which Li-ion intercalation takes place in graphite, the preferred material for anode in Li-ion batteries, is a fundamental topic to improve the capabilities of this type of batteries. Graphite is the material most commonly used as anode, due to its high load capacity and low cost.
