Temperature control mechanism for battery cell

A battery cell comprising:

• an anode having a single current collector and a plurality of active areas, wherein the plurality of anode active areas form first stacks;
• a cathode having a single current collector and a plurality of active areas, wherein the plurality of cathode active areas form second stacks;
• a solid-state electrolyte layer separating the anode and the cathode;
• a pouch laminate disposed over the anode and the cathode;
• and
• a temperature control mechanism centrally located within the pouch laminate, wherein the temperature control mechanism:
• is disposed between the first and second stacks such that the temperature control mechanism is centrally located within battery cell;
• is formed from a flexible material that flexes upon the application of a fluidic pressure;
• includes passageways through which a heat transfer fluid travels;
• and
• is configured such that when the heat transfer fluid travels through the passageways, the temperature control mechanism is configured to expand and apply pressure on the battery cell.
