Abstract
High-resolution electron microscopy and lithium-7 nuclear magnetic res onance measurements were carried out for a disordered carbon material, prepared by heat treatment of polyphenylene, in which lithium was sto red electrochemically. The nuclear magnetic resonance spectrum suggest s the existence of Li-2 covalent molecules in the carbon material. Thi s extra covalent site of lithium storage promises extraordinarily high energy density for secondary batteries.
