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 cycle life [1, 2]. Most commercialized LIB employ graphite as the principal material for the anode, however, this material has a low theoretical capacity. Consequently, a wide range of materials has been considered to replace or modify it to increase the capacity of the anodes [3]. On the other hand, it was shown that the use of carbonaceous highly ordered two-dimensional porous material CMK-3 as anodes in LIB leads to a significant increase in the conduction of lithium-ion and electrons [4]. In this work, we present a new material based on CMK-3, functionalized by NiFe2O4 spinel, using different impregnation methods. The employment of this particular spinel is grounded on his promising features, e.g. it has a high theoretical capacity, and both Ni and Fe are low-cost abundant elements (which is important for the possible applicability to the industry)
