The first stage, electrode manufacturing, is crucial in determining the performance of the battery.
Batteries produce electric energy though the chemical reaction occurring inside the cell. The key to carry out that reaction is the motion of electrons. Electrons are negatively charged particles that generate electricity while moving. This flow is possible with the use of two different metals acting as conductors.
Electrode manufacturing is the first step in the lithium battery manufacturing process. It involves mixing electrode materials, coating the slurry onto current collectors, drying the coated foils, calendaring the electrodes, and further drying and cutting the electrodes. What is cell assembly in the lithium battery manufacturing process?
The metals inside a battery are interconnected by a substance capable of conducting electrons, called the electrolyte. Electric vehicles use batteries built of interconnected cells. The power systems used are different from one another mainly by their useful life, chemical composition, and weight.
