Abstract
A method for manufacturing a nickel-metal hydride battery includes: a first step of preparing a first nickel-metal hydride battery having a positive electrode including nickel hydroxide (Ni(OH)2); and a second step of manufacturing the second nickel-metal hydride battery by performing 600% overcharging to the prepared first nickel-metal hydride battery. The 600% overcharging is a process for supplying the first nickel-metal hydride battery with an amount of electric power of 600% of the rated capacity of the first nickel-metal hydride battery.
Claims5
A method for manufacturing a nickel-metal hydride battery, the method comprising:
- preparing a first nickel-metal hydride battery having a positive electrode including nickel hydroxide;
- and
- manufacturing a second nickel-metal hydride battery by charging the first nickel-metal hydride battery to change, into nickel oxide, at least part of the nickel hydroxide in the positive electrode of the first nickel-metal hydride battery, wherein
- nickel in the nickel oxide has a valence of more than 3.
A method for manufacturing a nickel-metal hydride battery, the method comprising:
- preparing a first nickel-metal hydride battery having a positive electrode including nickel hydroxide;
- and
- manufacturing a second nickel-metal hydride battery by supplying the first nickel-metal hydride battery with an amount of electric power of more than or equal to 600% of a rated capacity of the first nickel-metal hydride battery.
A nickel-metal hydride battery comprising a positive electrode, wherein the positive electrode includes nickel hydroxide and nickel oxide, and nickel in the nickel oxide has a valence of more than 3.
