We claim: 1. A monoblock battery, comprising: a battery case comprising: a first container having at least one partition dividing the interior of said first container into a plurality of cell compartments, and a second container having at least one partition dividing the interior of said second container into a plurality of cell compartments, said first container joined to and co-operating with said second container to form at least one coolant channel disposed between said first container and said second container so that a portion of the coolant channel is enclosed within the battery when said first container is joined to said second container, said coolant channel cooperating with an inlet and an outlet, said inlet integrally connected to an exterior portion of said first container, said outlet integrally connected to an exterior portion of said second container, and said coolant channel, inlet and outlet are further configured so coolant exiting the coolant channel is not routed through an interior portion of the second container to pass through the outlet; and a plurality of electrochemical cells disposed within said battery case. 2. The battery of claim 1, wherein said coolant channel includes a rib of said first container abutting a surface of said second container. 3. The battery of claim 1, wherein said coolant channel is fluid-tight. 4. The battery of claim 1, wherein said coolant channel comprises a tortuous path. 5. The battery of claim 1, wherein said inlet or said outlet is positioned at a sidewall of said first or second container. 6. The battery of claim 1, wherein said battery case comprises a plastic. 7. The battery of claim 1, wherein said plurality of electrochemical cells are nickel-metal hydride electrochemical cells. 8. The battery of claim 1, wherein said coolant channel is configured to transfer heat to said electrochemical cells. 9. The battery of claim 1, further comprises an outer coolant channel integrally formed on an outer wall of said battery case. 10. The battery ease of claim 1, wherein said battery case includes both gaseous cooling and liquid cooling. 11. The battery of claim 1, further comprising a plurality of ribs positioned at an exterior portion of said battery case. 12. The battery of claim 1, wherein said electrochemical cells include an alkaline electrolyte. 13. The battery of claim 1, wherein said first container is welded to said second container. 14. The battery of claim 1, wherein said first container is joined to said second container utilizing an adhesive. 15. The battery of claim 1, wherein said electrochemical cells comprise nickel-metal hydride. 16. The battery of claim 1, further comprising a pressure relief vent. 17. The battery of claim 1, further comprising a gas-permeable hydrophobic membrane covering an opening of at least one of said cell compartments of the first or second container.
