Abstract
This invention provides an actively controlled battery with a programmed-timing actuation capability. The battery comprises a first electrochemical assembly, at least a second electrochemical cell assembly electronically connected in parallel with the first assembly, and control means in control relation to the first assembly and the second assembly, wherein at least one of the assemblies comprises a metal-air cell comprising a cathode being isolated from outside air through a controllable air vent and at least one of the assemblies comprising an electrochemical cell comprising an anode active material being initially isolated from an electrolyte fluid through a control valve, with both the air vent and control valve being regulated by the control means in a programmed-timing fashion. The battery has an exceptionally long operating life and is particularly useful for powering microelectronic or communication devices such as mobile phones, laptop computers, and palm computers.
