Prismatic Battery Assembly Line / Lithium Ion Battery Tech Consultancy
How To Set Up A Prismatic Battery Assembly Line, Lithium Ion Battery Tech Consultancy
1. Description :
The industrial production of lithium-ion batteries usually involves 50+ individual processes. These processes can be split into three stages: electrode manufacturing, cell fabrication, formation and integration.In order to achieve stringent safety and performance requirements, a high level of precision, uniformity, stability, and automation have become necessary in the battery manufacturing process.
If you consider setting up a lithium ion battery plant, then need tech and consulting and advisory services. We provide latest technology developments that will reduce the material and manufacturing costs of lithium-ion battery cells and further enhance their performance characteristics.
2. Applications : We provide the tech consult and support on how to produce lithium ion batteries and improve the process.
3. Specifications :
| Clean room class | Dry room (dew point) | Temperature | Annotations | |
| Mixing | ISO 8 | / | 22 ± 2 °C | The electrode manufacturing takes place under clean room conditions, since foreign particles in the coating cannot be removed in the later process by cleaning methods (e.g. suction). |
| Coating | ISO 7 | semi-dry (5°C to -5°C) | ||
| Drying | ||||
| Calendering | ISO 7 - ISO 8 | |||
| Slitting | ||||
| Vacuum drying | (0°C to -30°C) | |||
| Separation | min. ISO 7 | Dry (-25°C to -35°C) | 22 ± 2 °C | The cell assembly must be carried out under dry conditions, as water inside the cell leads to strong quality losses (service life) and to a safety risk (formation of hydrofluoric acid). |
| Stacking / Winding | Dry (-40°C to -50°C) | |||
| Packaging | ||||
| EL filling | Extra dry (-50°C to -70°C) | |||
| Formation | / | / | 22 ± 3 °C | Cell finishing takes place in a normal environment. Since the cell is already sealed and degassing takes place in a vacuum chamber, there are fewer requirements for the particle environment and humidity |
| Degassing | ||||
| HT aging | 30 °C to 50 °C | |||
| NT aging | 22 ± 3 °C | |||
| EOL testing |
