The model predicts how much thermal energy we need in order to remove the moisture and NMP from the electrodes. It is accompanied with the increasing temperature of other materials and some heat lost to environmental. The thermal energy consumption of the drying process calculation could be divided into two parts. (1) The energy for increasing the temperature of all component materials. (2) The energy for evaporating the moisture and NMP away from the feedstock. Through the thermal properties and some basic physical formulas, we obtain theoretical results for both parts respectively. And then, we take the empirical energy efficiency of the vacuum dryer into account to get more realistic data.
