Abstract
Official abstract text for this publication.
A calcium-based secondary cell including, as a positive-electrode active material, a molybdenum oxide-based material containing molybdenum in an oxidation state of 4 or more and 6 or less.
First claim
Opening claim text (preview).
The invention claimed is: 1. A calcium-based secondary cell comprising: a negative electrode that includes a negative-electrode active material, said negative-electrode active material being capable of accepting and releasing calcium ions, a positive electrode that includes a positive-electrode active material, said positive-electrode active material being capable of accepting and releasing calcium ions, an electrolyte arranged between the negative electrode and the positive electrode, wherein the positive-electrode active material is a molybdenum oxide-based material containing molybdenum oxide-based material selected from the group consisting of alpha-MoO 3 , beta-MoO 3 , CaMoO 3 , Mo 17 O 47 , Mo 18 O 52 , Mo 9 O 11 , and Mo 9 O 24 . 2. The cell according to claim 1 , wherein the negative electrode material is a calcium metal anode. 3. The cell according to claim 1 , wherein the negative electrode material is a Ca—Si or Ca—Sn alloy. 4. The cell according to claim 1 , wherein the electrolyte contains Ca(BF 4 ) 2, calcium triflate or Ca(PF 6 ) 2 . 5. The cell according to claim 1 , wherein the electrolyte contains a mixture of ethylene carbonate (EC) and propylene carbonate (PC). 6. The cell according to claim 1 , wherein the cell further comprises a temperature control element. 7. A non-aqueous calcium-based secondary battery comprising a calcium-based secondary cell according to claim 1 . 8. A vehicle, an electronic device or a stationary power generating device comprising a non-aqueous calcium-based secondary battery according to claim 7 .
