ELECTRODE LAMINATE AND ALL-SOLID LITHIUM BATTERY
PROBLEM TO BE SOLVED: To provide a method by which an electrode laminate of an electrode layer and a separator layer can be obtained without causing a side reaction of an electrode active material and a solid electrolyte during sintering even if the laminate of the electrode layer containing lithium-titanium composite salt as an electrode active material, and the separator layer is sintered at 600°C or higher.SOLUTION: An electrode laminate is arranged by laminating an electrode layer containing an electrode active material, and a separator layer containing a solid electrolyte in this order. In the electrode laminate, the electrode active material is composite oxide of lithium and titanium; and the solid electrolyte contains lithium phosphate and/or lithium niobate. The electrode layer may be an electrode composite layer containing an electrode active material and a solid electrolyte consisting of perovskite type oxide containing lithium.SELECTED DRAWING: Figure 1
【課題】電極活物質としてリチウムとチタンの複合塩を含む電極層と、セパレータ層との積層体を６００℃以上で焼結しても、電極活物質と固体電解質が焼結中に副反応せずに、電極層とセパレータ層の電極積層体を得る方法を提供する。【解決手段】電極活物質を含む電極層と、固体電解質を含むセパレータ層とがこの順に積層してなる電極積層体であって、前記電極活物質が、リチウムとチタンの複合酸化物であり、前記固体電解質が、リチウムリン酸塩及び／又はリチウムニオブ酸塩を含むことを特徴とする電極積層体を用いる。また、電極層が、電極活物質と、リチウムを含むペロブスカイト型酸化物である固体電解質を含む電極複合体層であってもよい。【選択図】図１
