Document Type and Number:
Japanese Patent JP2598891
Kind Code:
B2
Abstract:
PURPOSE:To suppress capacity drop at a negative electrode by brining a negative electrode, equipped with hydrogen occluding alloy, into contact with the inner face of an armored cell can either directly or through heat conductive material of grease. CONSTITUTION:A negative electrode 2, situated at the outer face of an electrode body and equipped with hydrogen occluding alloy, is brought into contact with the inner face of an armored cell can 4 either directly or through conductive material of grease. Then heat generating at the negative electrode during charge is conducted from the negative electrode, which is situated at the outer face of the electrode body, to the metal armored cell can 4, and the heat is quickly released from the surface of the can 4, being the negative electrode cooled. Contact of the negative electrode 2 and the can 4 through heat conductive material of grease increases cooling effect since heat generating at the negative electrode becomes particularly easy to conduct to the can 4. Therefore capacity deterioration at the negative electrode can be suppressed.
