Comparison Between the Electrochemical Behavior of Disordered Carbons and Graphite Electrodes in Connection with Their Structure

“…Carbonaceous materials for Li-ion batteries, which are currently available from different commercial and laboratory sources, belong to two major classes: graphitic and nongraphitic ͑disordered͒ carbons. 1 While Li-ion intercalation into graphitic carbons has been extensively studied during the last 20 years 2 ͑since this phenomenon was first observed in the mid-1970s 3 ͒, much less information has been obtained on the nature of Li-ion insertion into disordered carbons. These carbons may find attractive applications as anodes for Li-ion batteries for two reasons: First, typical synthetic routes for their fabrication consist of pyroloysis of organic polymers or hydrocarbon precursors at temperatures below 1500°C.…”
