PURPOSE:To prevent degadation of a hydrogen storage electrode due to repeated charging and discharging by using a hydrogen storage alloy formed in a thin film on a secondary battery. CONSTITUTION:A hydrogen storage alloy formed in a thin film is used as a negative electrode 1 of a secondary battery. A positive electrode 2 is made of nickel oxide, and is housed in upper and lower vessels 4, 5 made of stainless steel or brass, while a separator 3 made of polystylene is interposed between the negative electrode 1 and the positive electrode 2. The vessels 4, 5 are connected via an insulator 6 such as resin. Nickel oxyhydroxide or silver oxide as well as the nickel oxide may also be used as the metal material of the positive electrode. The secondary battery with the negative electrode 1 consisting of the hydrogen storage battery with the thin film can thus maintain the life of the battery long enough for charging and discharging over a number of cycles. |
