A method of preparing an anode material using sepiolite clay having channel-like interstices in its lattice structure. Carbonaceous material is deposited in the channel-like interstices of the sepiolite clay and then the sepiolite clay is removed leaving the carbonaceous material. The carbonaceous material is formed into an anode. The anode is combined with suitable cathode and electrolyte materials to form a battery of the lithium-ion type.
