“…For these uses, electrode materials showing higher capacities in LIBs will be needed. The present authors think the B/C materials are one of the candidates of the anode of LIBs because of their large reversible capacities more than 400 mAh/g [17][18][19]. Among the previous publications, Way and Dahn first reported the evaluation of B/C material having the composition of B0.17C0.83, which was prepared through the CVD method using boron trichloride and benzene as starting materials, and found that the material showed the reversible capacity of 437 mAh/g as the anode of LIBs [17].…”

Boron/carbon materials (B/C materials) having graphite-like layered structure were prepared and characterized as the anodes of lithium (Li) ion batteries (LIBs). Li was electrochemically intercalated and de-intercalated into and out of the host B/C materials, respectively. The material with a composition of BC7.9 showed the highest reversible capacity about 580 mAh/g among the materials prepared in this study. Ex-situ XRD study indicated that the intercalation of Li into the layers of B/C materials occurred during the discharge process to form finally first stage compound. 7 Li and 11 B-NMR observations suggested that the intercalated Li had an interaction with the boron in B/C materials. This interaction could make larger capacities of B/C materials as the anodes of LIBs.
