RECENT TRENDS IN CARBON NEGATIVE ELECTRODE MATERIALS

The use of graphite-type materials as the negative electrodes for rech argeable lithium batteries is increasing. For graphite-type materials, we proposed the intercalation mechanism taking into account the influ ence of crystallite size and stacking of the graphitic layers. We foun d graphite-type materials with a reversible capacity of 430 mAh g(-1) over a theoretical limit capacity of 372 mAh g(-1). This higher capaci ty is due to cavities existing in carbon that are capable of storing l ithium ions. (C) 1997 Elsevier Science S.A.
