Abstract
A thermal release layer for electrode materials in a battery cell is provided. The battery cell can include a terminal and an electrode, in contact with the terminal. The battery cell can include a first material that conducts electricity to establish electrical continuity with the terminal. The battery call can include a second material that, in response to a temperature of the electrode reaching or exceeding a temperature threshold, expands to reduce the electrical continuity with the terminal.
