Field of the Invention This invention relates to batteries and, more particularly, to an environmentally safe and operable battery. 2. Description of the Related Art Batteries are essential components of almost all electronic devices. For example, many computers include a number of batteries and even televisions and telephones include a battery. Many computer systems require more than one battery. A computer system that uses batteries for all of its needs may have, e.g., a portable computer, a desktop computer and a telephone that all require individual batteries. A number of general properties are common to most batteries. Batteries have a positive and negative terminal, which are referred to as the positive and negative terminals. Positive and negative terminals are also referred to as the positive and negative plates. One plate is always the positive terminal and the other plate is always the negative terminal. Each battery also has an internal positive and negative electrochemical cell of some type. The positive and negative terminals are connected to the positive and negative electrochemical cells, respectively. The positive and negative electrochemical cells are separated by an electrolyte. A separator (e.g., a membrane or a fibrous separator) is disposed between the positive and negative cells and serves to insulate the positive and negative cells from each other. Batteries may include a portion of an insulating housing material, which insulates the positive and negative terminals from each other and may also insulate the positive and negative cells from each other. An example of a conventional battery is described in U.S. Pat. No. 6,030,812, which is incorporated herein by reference. The '812 patent discloses a battery that includes an electrolyte, a positive electrode, a negative electrode and an insulating separator. The positive electrode, negative electrode and insulating separator are disposed between a positive terminal and a negative terminal. A sealing cover is disposed over the positive and negative terminals. One problem that conventional batteries have is that the amount of amperage that can be provided is limited. In general, a conventional battery can provide a maximum of only about one amp of amperage at a time. An example of a conventional battery that can be used in a typical electronic device is a nickel cadmium battery. A nickel cadmium battery includes a positive terminal, a negative terminal and an electrochemical cell that includes cadmium and nickel as the positive and negative terminals, respectively. The electrochemical cell is disposed between the positive and negative terminals. The amount of amperage that can be provided by a nickel cadmium battery is limited because the negative terminal is formed from cadmium and the positive terminal is formed from nickel. The combination of cadmium and nickel is not capable of providing a large amount of amperage. Consequently, nickel cadmium batteries are not commonly used in other than a few specialized applications, for example, for automobiles. One reason that conventional batteries, such as nickel cadmium batteries, cannot provide a large amount of amperage is that a large amount of amperage requires a large amount of oxygen gas. For example, oxygen gas is created when an electrochemical cell is overcharged. The creation of oxygen gas is important because oxygen gas is capable of lifting moisture from the electrolyte. Unfortunately, when oxygen gas is capable of lifting moisture from the electrolyte, the moisture creates a hydration layer on the negative terminal. Because the hydration layer is soluble in the electrolyte, the electrochemical cell cannot provide amperage when the hydration layer is formed on the negative terminal.
