摘要：

We investigated sp(2) carbon microrods resulting from the reaction of lithium with hexachlorobenzene. The material exhibits high surface area (200-340 m(2)/g, depending on heat treatment) and a reversible lithium storage capacity in excess of 500 mA h/g. The discharge/ charge behavior of the material resembles that of high specific capacity non-graphitic carbon. Without distinguishable plateaus, the reversible intercalation of lithium occurs at a broad potential window below 1 V vs. Li/Li+. A possible mechanism for the rod formation, based on SEM results, is briefly considered. (C) 2006 Elsevier Ltd. All rights reserved.
