1. Lithium battery material thermal kiln supporting dust removal
The powder leveling, vibration, screening, blanking and unloading stations on the lithium battery material sintering kiln production line will generate dust, and dust overflow will cause material loss and pollute the environment And it will damage some precision equipment, which requires a dust collector with excellent performance to collect, filter and recycle the dust
2. Battery material mixing operation dust removal
Vacuum planetary mixer mixes the positive and negative electrode solid battery materials evenly, then adds solvent and stirs them into a slurry. Dust escapes during the feeding, mixing, and stirring operations of the production line, which requires The industrial dust collector collects and filters the escaping dust, and the indoor discharge meets the standard.
3. Pole sheet slitting, sheet making, die cutting, battery winding or stacking equipment supporting dust removal
- Automatic slitting machine Continuously slitting wide pole pieces into a number of narrow pieces of required width, the cutting dust needs to be treated
- Automatic tab welding machine, laser tab forming machineWelding tabs, sticking protective tape, wrapping tabs, or using laser cutting to form tabs, etc. for the slit pole pieces and pole pieces, etc., for the subsequent winding process, welding and cutting fumes need to be treated
- Die-cutting is the gap coating or continuous coating ( One-side tab) die-cutting for the subsequent lamination process; Rewinding die-cutting is to roll continuously coated pole pieces (both tabs) The tabs are formed by metal molds, and then rolled up for subsequent slitting and winding processes. The dust and leftovers generated before and during die-cutting need to be collected and treated.
- Cylindrical winding machine, square winding machine Wind the pole piece made by the film making process or winding die-cutting machine into the battery core of lithium-ion battery, which will adhere to the surface during winding dust control.
- Full-auto lamination machine is a single pole made in the die-cutting process The cells are stacked into lithium batteries, and the dust on the surface is treated during the stacking process.
4. Dust control for laser welding, cleaning and marking operations of cell packaging
When welding, cleaning and marking lithium battery packaging shells, smoke and dust will be generated, which needs to be dealt with in time, and the smoke contains There are sparks, and flame-retardant design and treatment are required.
The outer packaging of lithium batteries is mostly made of aluminum alloy. When marking and engraving dust, it is necessary to consider anti-static and anti-spark.
