Abstract
Official abstract text for this publication.
There is provided a secondary battery including: a positive electrode containing manganese dioxide and/or manganese hydroxide, a conductive aid, and a hydroxide-ion-conductive inorganic solid electrolyte; a negative electrode containing zinc and/or zinc hydroxide, a conductive aid, and a hydroxide-ion-conductive inorganic solid electrolyte; and a separator containing a hydroxide-ion-conductive inorganic solid electrolyte, the separator separating the positive electrode from the negative electrode.
First claim
Opening claim text (preview).
What is claimed is: 1 . A secondary battery comprising: a positive electrode containing manganese dioxide and/or manganese hydroxide, a conductive aid, and a hydroxide-ion-conductive inorganic solid electrolyte; a negative electrode containing zinc and/or zinc hydroxide, a conductive aid, and a hydroxide-ion-conductive inorganic solid electrolyte; and a separator containing a hydroxide-ion-conductive inorganic solid electrolyte, the separator separating the positive electrode from the negative electrode, wherein the secondary battery does not contain an alkaline electrolytic solution. 2 . The secondary battery according to claim 1 , wherein the hydroxide-ion-conductive inorganic solid electrolyte contained in the positive electrode, the negative electrode, and the separator comprise layered double hydroxide (LDH). 3 . The secondary battery according to claim 1 , wherein the conductive aid contained in the positive electrode and the negative electrode comprises a carbon material. 4 . The secondary battery according to claim 1 , wherein the positive electrode, the negative electrode, and the separator contain moisture. 5 . The secondary battery according to claim 1 , wherein the hydroxide-ion-conductive inorganic solid electrolyte contained in the positive electrode forms a network in the positive electrode, and the hydroxide-ion-conductive inorganic solid electrolyte contained in the negative electrode forms a network in the negative electrode. 6 . The secondary battery according to claim 1 , wherein the conductive aid contained in the positive electrode forms a network in the positive electrode, and the conductive aid contained in the negative electrode forms a network in the negative electrode. 7 . The secondary battery according to claim 2 , wherein the hydroxide-ion-conductive inorganic solid electrolyte contained in the positive electrode, the negative electrode, and the separator has a structure in which particles of the LDH are bonded to each other. 8 . The secondary battery according to claim 1 , wherein the hydroxide-ion-conductive inorganic solid electrolyte contained in the positive electrode and the negative electrode has higher electron conductivity than that of the hydroxide-ion-conductive inorganic solid electrolyte contained in the separator.
