Definitions
- the present invention relates to a nickel-metal hydride rechargeable battery, and more particularly to a nickel-metal hydride rechargeable battery intended for prolonged life.
- an object of the present invention is to provide a nickel-metal hydride rechargeable battery with prolonged life by limiting a working range of hydrogen-absorption capacity of hydrogen-absorption alloys.
- a nickel-metal hydride rechargeable battery according to the present invention including a positive electrode having nickel hydroxide and a negative electrode having a hydrogen-absorption alloy, is designed to be charged and discharged in the range of 20-60% of hydrogen-absorption capacity of the alloy.
- a positive electrode having nickel hydroxide and a negative electrode having a hydrogen-absorption alloy is designed to be charged and discharged in the range of 20-60% of hydrogen-absorption capacity of the alloy.
- the nickel-metal hydride rechargeable battery of the invention employs hydrogen-absorption alloys of 10-25 ⁇ m in average particle diameter.
- increased total surface area of the alloy enables the nickel-metal hydride rechargeable battery to be capable of heavy loading operation.
- alkaline electrolyte per negative electrode capacity is usually around 1.5 g/Ah, it is increased to 1.5-3 g/Ah in the invention. This is because there is a margin to gas absorption capacity resulted from operations with no full use of hydrogen-absorption capacity. Thus, a life shortening caused by decrease in alkaline electrolyte is suppressed.
- Both increased output power and prolonged life are also attained by arranging a facing area, per negative electrode capacity, between opposing electrodes to be 45-65 cm 2 /Ah.
- FIG. 1 is a graph showing results in the life tests on nickel-metal hydride rechargeable batteries of an embodiment of the present invention and a conventional example; and,.
- FIG. 2 is a partially broken perspective view of a nickel-metal hydride rechargeable battery.
- a nickel-metal hydride rechargeable battery 1 includes positive electrode plates having nickel hydroxide as its active material, and negative electrode plates having hydrogen-absorption alloy.
- An electrode plate group 3 is formed by alternately stacking of the negative electrode plates and the positive-electrode plates covered with pouch-shaped separators made of non-woven polypropylene fabric. The electrode plate group 3 is placed, together with an electrolyte, in a battery case 2 made of synthetic resin. An opening of the case 2 is closed with a lid 5 having a safety vent 4 .
- Leads 6 are extended from an upper edge of each positive electrode plate on one side of the electrode plate group 3 , and are connected to a positive electrode terminal 7 by resistance welding. In the same way, leads 6 are extended from an upper edge of each negative electrode plate on the other side of the electrode plate group 3 , and are connected to a negative electrode terminal 8 by resistance welding.
- the positive and negative electrode terminals 7 and 8 are attached to the lid 5 .
- the positive electrode plate with a capacity of 1 Ah and a reaction area per one side of 39.3 cm 2 was formed by filling a foamed nickel with a positive electrode material mainly comprising nickel hydroxide except an unfilled margin with a width of 5 mm and attaching a nickel lead to the unfilled margin.
- the negative electrode plate, with a capacity of 1.25 Ah and a reaction area per one side of 39.3 cm 2 was formed by coating a punched metal with a negative electrode material mainly comprising hydrogen-absorption alloy of 20 ⁇ m in average particle diameter except an uncoated margin with a width of 5 mm and attaching a nickel lead to the uncoated margin.
- the nickel-metal hydride rechargeable battery 1 was finally assembled by filling up the battery case 2 with 20 g of an electrolyte mainly comprising potassium hydroxide, and then by sealing the case 2 with the lid 5 .
- an initial charge was performed at a current of 1 A for 5 hours, and then from the 2nd cycle the experiment was performed under condition of discharge at 1 A for 4 hours and charge at 1 A for 4 hours and 4 minutes.
- the absorbed hydrogen was used for the charge-discharge operations in the range of approximately 20-60% of the hydrogen-absorption capacity of the negative electrode alloy.
- the charge-discharge cycles were performed under the condition with a charge at 1 A for 7 hours and discharge at 1 A until discharge voltage became 1 V.
- the absorbed hydrogen was used for the charge-discharge operations in the range of approximately 10-80% of the hydrogen-absorption capacity of the negative electrode alloy.
- FIG. 1 shows changes in capacity ratio for each battery. Under a conventional working condition, the capacity ratio declined to 65% after 150 cycles. While in the embodiment of the invention, enough capacity was maintained even after 6000 cycles, and life characteristics were proved to have been remarkably improved. Even taking different values of discharge capacity per cycle, approximately 7 Ah in the conventional example and approximately 4 Ah in the example of the invention, into considerations, the total discharge capacity is proved to be larger in the present invention.
- the nickel-metal hydride rechargeable battery of the invention cracks and corrosions in the hydrogen-absorption alloy of the negative electrode, which determines the life of the rechargeable battery, is prevented by limiting the charge and discharge operations to be performed in the range of 20-60% of the hydrogen-absorption capacity of the hydrogen-absorption alloy; whereby the total quantity of electricity available for charge-discharge increases and the life characteristics as the rechargeable battery are improved so as to assure the battery provided with high reliability for a long time.
