Li-Ion batteries (LIB) have been exhaustively studied because of their potentialities for greentransportation and renewable energy storage due to their high power, high energy density, and long cyclelife. Most commercialized LIB employ graphite as the principal material for the anode, however, thismaterial has a low theoretical capacity. Consequently, a wide range of materials has been considered toreplace or modify it to increase the capacity of the anodes. On the other hand, it was shown that the useof carbonaceous highly ordered two-dimensional porous material CMK-3 as anodes in LIB leads to asignificant increase in the conduction of lithium-ion and electrons. In this work, we present a newmaterial based on CMK-3, functionalized by NiFe2O4 spinel, using different impregnation methods. Theemployment of this particular spinel is grounded on his promising features, e.g. it has a high theoreticalcapacity, and both Ni and Fe are low-cost abundant elements (which is important for the possibleapplicability to the industry).
