A research group led by Lecturer Motoaki Matsuo and Professor Shin-ichi Orimo at Institute for Materials Research, Tohoku University has achieved the synthesis of the new complex hydride Na2(BH4)(NH2) with both sodium fast- ionic conductivity and high electrochemical stability. The result suggests that the complex hydride could be a potential candidate for solid electrolyte of the all-solid-state sodium-ion secondary batteries. The result was published in Applied Physics Letters (100, 203904, 2012).
