“…In industrial companies, heat energy represents 40 to 60% of the overall energy consumption and is mainly used for drying processes [14]. Examples range from drying food to prolonging the shelf life over drying straw, wood or paper to drying electronic components such as semiconductors or LIB cells.…”

As the world’s automotive battery cell production capacity expands, so too does the demand for sustainable production. Much of the industry’s efforts are aimed at reducing the high energy consumption in battery cell production. A key driver is electrode drying, which is currently performed in long ovens using large volumes of hot air. Several drying technologies from other industries could reduce energy consumption and greenhouse gas emissions if successfully applied to battery cell production. High process and quality requirements must be met when adapting these technologies for battery cell production. Evaluating the technologies against these requirements is difficult due to the technological novelty of this industry and the associated lack of data. Furthermore, the significant differences in drying technologies render a comparison even more challenging. One objective of this study was to evaluate drying technologies and identify those that could be best adapted to lithium-ion battery cell production. Near-infrared and laser drying were found to be the best in terms of energy efficiency, cost savings and other parameters. Another aim was to analyse, in more detail, the technological challenges and the advantages and disadvantages of the top-ranked drying technologies. Finally, the saving potential for greenhouse gas emissions of near-infrared and laser drying was calculated for a global production scenario of LIB cells in 2030. The saving potential in this scenario would amount to 2.63 million metric tonnes (Mt) CO2eq per year if near-infrared drying was applied in all global LIB cell production facilities within the mentioned scenario and 1.47 million Mt CO2eq per year for laser drying.

“…In the dehydration technique, three principles of moisture removal are used: membrane, evaporation and cryoconcentration. Membrane technologies are becoming more common in the problems of desalination and wastewater treatment [9]. Membrane technologies are not widely used for the concentration of juices and extracts.…”

A comparative analysis of traditional methods for the food solutions concentration is given. The main problem of classical evaporators is identified, which is associated with the impossibility of obtaining high concentrations of the finished product due to a sharp increase in its viscosity and temperature through the formation of a boundary layer. A scientific and technical hypothesis has been formulated, representing a possible solution to this problem by providing a volume supply of energy directly to the moisture of the product. Thermophysical scheme of evaporation processes by traditional and innovative methods is considered. Their fundamental differences are highlighted and the relevance of the development of an innovative evaporation method is substantiated. The scheme of the innovative evaporator is presented, which allows to obtain the finished product in the solid phase with a final concentration of up to 90 °brix. By the example of apple juice, experiments were conducted to study the effect of pressure of the electromagnetic field on the steam output of the apparatus. Dependencies that indicate a constant evaporation rate throughout the entire process, up to a concentration of 80-85 °brix, were built. The product temperature did not exceed 35-40 °C, which may indicate its high nutritional value. The above data confirm the formulated hypothesis about the possibility of transition in the process of evaporation from the boundary conditions of the 3rd type to the boundary conditions of the 2nd type by the using microwave energy. On the basis of the obtained results, a model in the criterial form was obtained, which makes it possible to accurately calculate the performance of a microwave vacuum evaporator in certain ranges of the number of energetic action and the obtained dimensionless complex.
