The researchers plan to incorporate the TPV cell into a grid-scale thermal battery. The system would absorb excess energy from renewable sources such as the sun and store that energy in heavily insulated banks of hot graphite. ... With the new TPV cell, the team has now successfully demonstrated the main parts of the system in separate, …
When the battery generates excess heat, the PCM absorbs the heat and undergoes a phase change, storing the heat energy [36, 43]. As the temperature of the battery cells decreases, the PCM solidifies and releases the stored heat, keeping the battery warm and maintaining the temperature within a safe range.
