Title:
MANUFACTURE OF ELECTROLYTE PLATE FOR FUSED CARBONATE FUEL CELL AND ELECTROLYTE PLATE FOR FUSED CARBONATE FUEL CELL
Document Type and Number:
Japanese Patent JP2799842
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To reduce a loss quantity of electrolyte, and maintain battery initial performance over a long period of time by using an anodic oxidation type lithium aluminate particle and alimina fiber as a reinforcing material in an electrolyte plate.
SOLUTION: An aluminium oxide having a porous structure is manufactured by electrochemically oxidizing metallic Al 1 in a sulfuric acid aqueous solution 2. Al remaining without being anodically oxidized is selectively dissolved by using a basic aqueous solution 3 such as HaOH. The aluminium oxide formed by anodic oxidation is tutned into lithium by using lithium salt 4 such as Li2CO3, and is formed as anodic oxidation type lithium aluminate, and this is cracked into a submicron particle. Next, an electrolyte plate sheet is manufactured by using an organic compound 5 as a binding agent and a plasticizer, an anodic oxidation type lithium particle obtained in a process so far and a lithium aluminate particle 6 except it and an additive 7 of either one of base board strength improving alumina fiber and lithium aluminate fiber.
