The battery manufacturing process is a complex sequence of steps transforming raw materials into functional, reliable energy storage units. This guide covers the entire process, from material selection to the final product’s assembly and testing.
As detailed below, the 3 main phases are (i) electrode manufacturing, (ii) cell assembly and (iii) training, aging and test that validates the right performance of the assembled battery cells. 1. ELECTRODE MANUFACTURING
The manufacturing process of lithium-ion batteries consists largely of 4 big steps of electrode manufacturing, cell assembly, formation and pack production, in that order. Each step employs highly advanced technologies. Here is an image that shows how batteries are produced at a glance. STEP 1.
So, to find out what’s behind the energy storage revolution, let’s walk through each step. The lithium-ion battery manufacturing process is a journey from raw materials to the power sources that energize our daily lives.
The lithium-ion battery manufacturing process is a journey from raw materials to the power sources that energize our daily lives. It begins with the careful preparation of electrodes, constructing the cathode from a lithium compound and the anode from graphite.
Battery module and pack assembly Individual cells are then grouped into modules and assembled into battery packs. This step involves: Module Assembly: Cells are connected in series or parallel configurations to achieve the desired voltage and capacity.
Lithium battery formation is the first battery charging process after the lithium battery is filled with liquid. This process can activate the active materials in the battery and activate the lithium battery. At the same time, a side reaction …
