Customer ServiceThe 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.
Developments in different battery chemistries and cell formats play a vital role in the final performance of the batteries found in the market. However, battery manufacturing process steps and their product quality are also important parameters affecting the final products’ operational lifetime and durability.
Production steps in lithium-ion battery cell manufacturing summarizing electrode manufacturing, cell assembly and cell finishing (formation) based on prismatic cell format. Electrode manufacturing starts with the reception of the materials in a dry room (environment with controlled humidity, temperature, and pressure).
6.1 Formation The formation process involves the battery’s initial charging and discharging cycles. This step helps form the solid electrolyte interphase (SEI) layer, which is crucial for battery stability and longevity. During formation, carefully monitor the battery’s electrochemical properties to meet the required specifications.
It begins with the careful preparation of electrodes, constructing the cathode from a lithium compound and the anode from graphite. These components are meticulously coated onto metal foils to set the stage for the battery’s future performance. Next is the assembly of the battery cell.
In addition, the production of a battery consists of many individual steps, and it is necessary to achieve high quality in every production step and to produce little scrap. In a long process chain with, for example, 25 process steps and a yield of 99.5% each, the cumulative yield is just 88% .
