Abstract
A thermal runaway mitigation system cools fluid electrode material in a thermal battery to prevent a thermal runaway in the thermal battery. In response to a thermal runaway trigger, the thermal runway prevention system cools at least one of the fluid positive electrode material and the fluid negative electrode material. In some situations, the fluid material electrode material is sufficiently cooled to place the electrode material in a solid state.
Claims52
An apparatus comprising:
- a fluid electrode material comprising fluid negative electrode material and fluid positive electrode material;
- a reaction chamber comprising a fluid negative electrode formed from at least a portion of the fluid negative electrode material, a fluid positive electrode formed from at least a portion of the fluid positive electrode material, and a solid electrolyte between the fluid negative electrode and the fluid positive electrode;
- a heating system configured to maintain the fluid negative electrode and the fluid positive electrode in a fluid state;
- and
- a thermal runaway mitigation system configured to, in response to a thermal runaway trigger, cool at least a portion of the fluid electrode material to a temperature below the melting point of the at least the portion of the fluid electrode material to place the at least the portion of fluid electrode material in a solid state.
