| As electronic products have come to feature more sophisticated functions, more co***ct sizes and lighter weights, the sources of power that operate these products have been required to deliver increasingly higher levels of energy. To meet this requirement, nickel-metal hydride batteries have been developed and manu-factured with nickel hydroxide for the positive electrode and hydrogen-absorbing alloys capable of absorbing and releasing hydrogen at high-density levels for the negative electrode. Co***red to Ni-Cd batteries, Ni-MH batteries have about twice the energy density and a similar operating voltage. |
