The Cutting Edge in Lithium-Ion Batteries: Electrolyte Movement
Figure 1 shows a representation of this electrolyte movement. Figure 1. Model cross-section of cylindrical cell. The anode (red) expands during charging, squeezing electrolyte out of the top and bottom of the jelly roll and into the hollow core. Light blue arrows represent electrolyte (gray) movement.
Simulation of the Electrolytic Copper Refining Process
Input parameters are chemical composition of anodes and electrolyte. The control is built on the basis of the residual function system. It calculates control actions, namely current I and circulation rate of electrolyte V. The designed model enables to predict values of output indicators of the process and to correct its course.
