Multiple-output stack for small-volume thermal batteries

The invention provides a multiple-output stack for small-volume thermal batteries. An end heating plate, a negative voltage group drainage strip, a public pole drainage strip, a positive voltage group drainage strip I and a positive voltage group drainage strip II are sequentially arranged between two end plates; n single batteries, n+1 heating plates I and n current collection plates are arranged between the negative voltage group drainage strip and the public pole drainage strip, and one current collection plate and one single battery are arranged between the every two adjacent heating plates in a stacking way in the same order; m single batteries, m heating plates II and m-1 current collection plates are arranged between the public pole drainage strip and the positive voltage group drainage strip I, and one heating plate II and one current collection plate are arranged between the every two adjacent single batteries in a stacking way in the same order; l single batteries, l heating plates I and l-1 current collection plates are arranged between the positive voltage group drainage strip I and the positive voltage group drainage strip II, and one heating plate I and one current collection plate are arranged between the every two adjacent single batteries in a stacking way in the same order. The multiple-output stack for the small-volume thermal batteries can realize multiple voltage outputs under the condition of a small volume.
