A method is described to make a metal-containing non-amorphous hard-carbon composite material that is synthesized from furan-ring containing compounds. The metals described in the process include lithium and transition metals, including transition metal oxides like lithium titanates. The non-amorphous hard-carbon component of the metal-containing non-amorphous hard-carbon composite material is characterized by a d.sub.002 peak—in the X-ray diffraction patterns—that corresponds to an interlayer spacing of >3.6 Å, along with a prominent D-band peak in the Raman spectra. These metal-containing hard-carbon composites are used for constructing electrodes for Li-ion batteries and Li-ion capacitors.

Improved formulations of an interface material are described. These formulations may, in at least some cases, match and/or accommodate dimensional changes in the part and/or support structure throughout thermal processing (e.g., debind and sintering, or sintering only). Furthermore, these formulations may also maintain the property of resisting bonding between the interface and the part and/or support structure while also maintaining a physical separation between the part and support structure. In some cases, an improved interface material may accommodate strain associated with the shrinkage of a part (and optionally support structure) during sintering while also minimally impacting the ability of the part (and optionally support structure) to shrink or otherwise change in dimension. In some cases, the interface material may include one or more fugitive phases that are removed during thermal processing (e.g., through pyrolysis of the fugitive phase(s)).
