Research Abstract

We have worked on the functional advancement of complex hydrides as solid electrolyte and development of new electrode materials for lithium-ion batteries. It was found that the ion substitution for Li+ and [BH4]. complex anion is effective to improve the ionic conductivity of LiBH4. As a result, we succeeded in synthesizing new complex hydrides such as Li_3N_2IH_4 and Na_2BNH_6 with fast ionic conductivities. We also confirmed the lithium deintercalation of Li_xBC, a potential candidate for high-capacity electrode materials, from x=1 to x approximate to 0. 5.
