Study of an Industrial Electrode Dryer of a Lithium-Ion Battery Manufacturing Plant: Dynamic Modelling

Abstract

A dynamic model for lithium-ion battery (LIB) electrode
manufacturing and drying is developed in this paper. The
model is intended for analysis of different drying technologies, energy requirement calculations, and optimization and control of the drying process. The model shows
that the infrared drying is faster than the convective drying when the heat source temperature is the same. The energy required to evaporate the solvent can be reduced by
gradually changing the hot air temperature. Drying is the
most energy-intensive process in cell manufacturing, and
the cell manufacturing process is the biggest contributor
to greenhouse gas emissions in the LIB industry. Therefore, the presented model is useful for accurate estimation
of the environmental impact as well as for identifying the
appropriate measures to reduce energy requirements in the
rapidly growing LIB industry.
