Outline of Final Research Achievements |
We have investigated the possibility of superconductivity in LixBC and also the potentiality ofLiBC as a negative electrode in Li secondary battery. We have observed the drastic resistivity drop and diamagnetism at about 15 K in LixBC with x=0.8. The magnetic field dependence of the resistivity drop was quite similar to superconductivity. The magnetic field dependence was also similar to the type II superconductor. However, the sample dependence remained. We have prepared Si composited LiBC electrode by the mechanical milling method. The Si30% LiBC showed good cycle characteristics, and high capacity maintenance rate and Coulomb efficiency were obtained. In this case, the sample dependence also remained. The strain induced deterioration was observed in ourelectrodes, similar to other composited electrodes.
