Carbonaceous mesophase in form of mesocarbon microbeads has been recognized as a promising precursor material for anodes in rechargeable lithium-ion batteries. Recently, a method of synthesis of boron substituted mesophase via liquid phase co-pyrolysis of pitch and suitable boron compound has been reported. It has been anticipated that due to enhanced electron acceptor properties the boronated carbons can represent improved electrochemical performance. The present work is a first part of a wider study intended to assess the lithium insertion/deinsertion behaviour of different kinds of boron substituted mesophasic materials.
