| Abstract | Reusable electrochemical cells that can remain hermetically sealed to 400°C using commercially available and easy-to-machine components are described. Unlike most other cell designs, cell sealing and electrode electrical isolation are decoupled, allowing for consistent, low cost testing ( ∼ $2 in parts per cell rebuild) in a wide range of environments. Additional functionality (e.g. windows, valving, sensors) can be incorporated without compromising cell performance. Examples using these improved Conflat cells for extended room temperature testing and investigations of electrode phase transitions and accelerated electrolyte breakdown at elevated temperatures are provided. |
