As today's society is gradually shifting towards renewable transport methods such as electric vehicles, battery production is forecasted to grow signi cantly. This thesis seeks to evaluate the energy consumption of the lithium-ion battery manufacturing process and address ways to improve the energy e ciency of the current manufacturing process. This also includes assessing the potential of emerging technologies within the eld. The most energy demanding steps in a conventional manufacturing process are the electrode drying process and the dry room. These areas are the main focal points for this study. The evaporation energy and drying time of the electrode drying process is simulated for different drying techniques and tested based on different initial conditions using a mathematical model. The process simulation of the required energy for air ow heating and cooling is modeled using Aspen HYSYS. Further, the dry room is modeled using Aspen Plus based on different ambient conditions. Additionally, the potential for using maximum energy recovery (MER) networks based on the pinch approach is investigated. An estimate is made towards the equivalent production of the setups tested for and further, the ratio between energy consumption and production capacity is evaluated. The conventional convective drying process is modeled to have a load of around 2591 kW, this corresponds to an energy to produced cell capacity ratio of 32.7 Wh/Wh, and serves as the basis for comparison for the remaining designs. Radiation drying is by comparison slightly higher with a ratio of 34.4 Wh/Wh. The MER-network designs range from 18-20 Wh/Wh, implying that this design approach is highly viable compared to conventional setups. These MER-networks can also be further improved by integrating heat pumps around the pinch of the system. The dry room energy requirements are also modeled with a resulting load of 399 kW. This correlates to a total energy to produced capacity ratio of close to 5 Wh/Wh, depending on input conditions. Alternative production methods such as semi-solid electrode structures are able to bypass the need for electrode drying and thus the majority of the energy consumption. These methods also hold potential, and the combined energy requirement is estimated to be around 10-20 Wh/Wh. Laser drying is also discussed as a promising alternative due to the high
degree of control of the drying rate throughout the process
