Title:

CONNECTION STRUCTURE BETWEEN CELLS, AND CONNECTION METHOD

Document Type and Number:

Japanese Patent JP3838872

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To provide a connection structure between cells and connection method enabled to surely secure a good welding quality at all time by easily and surely performing a projection welding, and enabled to joint adjacent two single cells in a good connection state without apprehension of leakage.
SOLUTION: A plurality of welding protrusions 29, 30 for a projection welding are formed on both surfaces of a connector 27 respectively. An electrode plate 22 of a sealing body 20 of one cell Ba1 out of adjacent two cells, is jointed to one surface of the connector 27 by projection welding through the welding protrusion 29 for projection welding, and a cell case 19 of the other cell Ba2 is jointed to the other surface of the connector 27 by projection welding through the welding protrusion 30 for projection welding, thus, a plurality of cells Ba1-Ba6 are serially connected.
