A pure carbon-based material with applications in electrochemical processes was synthesized using sepiolite clay as a template and propylene as the organic precursor. Carbon fibers (1–1.5 µm long) were obtained whose orientation and shape resemble that of the original clay. The results indicated that there is a correlation of the reversible specific capacity obtained and the surface properties of the template sepiolite. The electrochemical performance for anode Li cells is related to the surface chemical properties rather than the BET surface area.
