The Effect of Boron Substitution in Carbon on the Intercalation of Lithium in Li x ( B z C 1 − z ) 6

摘要: Boron-substituted carbons, B[sub z]C[sub 1[minus]z], have been produced by chemical vapor deposition from benzene and boron trichloride precursors at 900 C. The voltage reversible capacity of Li/Li[sub x](B[sub 1[minus]z])[sub 6] cells were measured for the range concentrations 0 showed greater capacities than Li/coke cells, z > 0.10 exceeded that graphite. For example, 0.17]C[sub 0.83] specific was 437 mAh/g. This behavior is understood treating as an electron acceptor in carbon lattice. These materials appear to be promising candidates anode sin lithium ion rechargeable batteries.
