The voltage of each cell in the 18650 lithium battery pack has two conventional voltages: 3.7V for conventional lithium-ion batteries and 3.2V for lithium iron phosphate batteries; 5. The cells used in the assembly of 18650 lithium battery packs must be of the same type and properties, and new and old cells cannot be mixed together.
The manufacture of the lithium-ion battery cell comprises the three main process steps of electrode manufacturing, cell assembly and cell finishing. The electrode manufacturing and cell finishing process steps are largely independent of the cell type, while cell assembly distinguishes between pouch and cylindrical cells as well as prismatic cells.
Conventional processing of a lithium-ion battery cell consists of three steps: (1) electrode manufacturing, (2) cell assembly, and (3) cell finishing (formation) [8, 10]. Although there are different cell formats, such as prismatic, cylindrical and pouch cells, manufacturing of these cells is similar but differs in the cell assembly step.
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).
Manufacturing of Lithium-Ion Battery Cells LIBs are electrochemical cells that convert chemical energy into electrical energy (and vice versa). They consist of negative and positive electrodes (anode and cathode, respectively), both of which are surrounded by the electrolyte and separated by a permeable polyolefin membrane (separator).
In summary, the quality of the production of a lithium-ion battery cell is ensured by monitoring numerous parameters along the process chain. In series production, the approach is to measure only as many parameters as necessary to ensure the required product quality. The systematic application of quality management methods enables this approach.
Correct cell assembly is crucial for safety, quality, and reliability of the battery, and an essential step in achieving complete efficiency of the battery. Here is a more detailed look at the battery cell assembly process: Cathodes: Lithium cobalt oxide, lithium manganese oxide, lithium nickel cobalt aluminum oxide, or lithium iron phosphate.
