Definitions

- Magnesium has a large electric capacity per unit volume because the ions are multivalent ions. Magnesium has a higher melting point than lithium and is safe, and also has the advantage that the distribution of resources on the earth is small, the amount of resources is abundant, and it is inexpensive. Therefore, a magnesium ion battery using metallic magnesium as a negative electrode has attracted attention as a next-generation battery that replaces a lithium ion battery.

尚、図中の横軸は、参照極の電位を基準とした作用極の電位を表し、縦軸(mA/cm2)は各電位において観測された電流値を作用極の表面積で割った電流密度を表す。また、図1における実線は、調液直後の10サイクル目の結果を、図1における破線は、調液から1ヵ月経過後の10サイクル目の結果を表す。図2及び4~15における実線は、(調液直後の)10サイクル目の結果を表す。図3における実線は、(調液直後の)1サイクル目の結果を、図3における破線は、(調液直後の)10サイクル目の結果を、図3における点線は、(調液直後の)30サイクル目の結果をそれぞれ表す。
まず、J. Electrochem. Soc., 2014, 161, A593 に記載の方法に準じて、Mo6S8電極を作成した。次いで、作成したMo6S8電極を作用極に、Mgロッド(直径1.6mm;ニラコ社製)を対極及び参照極に使用し、ビーカーに実施例1で調製した電解液1を2ml加えて、3極式ビーカーセルを作成した。
室温下、カットオフ電位0.8V~1.9V(vs. Mg参照極)、0.1Cのレートで定電流充放電試験を行い、得られた充放電曲線を図16に示す。
尚、図中の横軸(mAh/g)は、各電位における放電容量を表し、縦軸は、参照極の電位を基準とした作用極の電位を表す。また、図16における実線は、1サイクル目の結果を、図16における点線は、5サイクル目の結果を表す。
