New Energy and Lithium Battery Filtration
Lithium battery production is judged on yield, and yield is decided by what reaches the electrode. Impurities carried in a process fluid end up in the coating, and a defect in the coated web is scrap rather than rework. Filtration is how the process fluid is kept to specification, batch after batch. Pullner supplies the elements that do that, to cell plants, cathode and anode material producers, coating line builders and battery equipment OEMs, usually as a second source into a line that is already running.
Typical Operating Conditions
Battery process fluids are unlike the water and process streams most filtration is built for. Three
conditions decide everything about the element.
Viscosity is high. Cathode and anode slurry carries binder and solvent, which means an element that
passes water comfortably may not pass slurry at all, or will build differential pressure fast enough
to starve the coating head.
Solids loading is high. Active material and conductive additive are meant to pass through; the
agglomerates and stray metal are not. The element has to separate those two, which is a harder job
than simple particle removal.
Chemistry is aggressive. Solvent systems rule out media on compatibility before micron rating is
even considered, which is why polypropylene is the standard choice here.
Filtration appears at several points in the line: cathode and anode slurry preparation, coating,
calendaring, slitting, and drying and baking. The duty changes at each, and so does the element.
Selection Parameters
Slurry duty is set by the formulation, not by the process step. Two plants running the same chemistry at different solids loading need different elements, so we specify against your numbers. Send these and we will come back with a format, a housing and a changeout interval.
| What we match against | Why it decides the element |
|---|---|
| Slurry viscosity | Sets whether the element passes the fluid, and at what differential pressure |
| Solids content | Decides solids-holding capacity, and therefore the changeout interval |
| Target particle size | Fixes the media grade and whether nominal or absolute is required |
| Fluid and binder chemistry | Confirms media compatibility before anything else is considered |
| Temperature | Polypropylene runs to 80 degrees C; above that the media changes |
| Flow rate | Sets the element count and the housing size |
| Allowable differential pressure | Sets the changeout point and the element construction |
| Maintenance cycle | An element changed twice as often is rarely the cheaper one |
Why Choose Pullner Filters For Your Water Treatment Systems
Más que un simple proveedor: somos su socio técnico en soluciones de filtración
Second-Source and Replacement Fit Check
Send the part number you run now and we will check dimensions, interface, media, temperature and pressure against your duty before quoting. If it does not fit we will say so. We do not claim a match to another manufacturer’s element until it has been validated on your process. That is your test to run, not our claim to make.
Engineering Support, Not a Catalog
In-house PMI pore analysis, SEM and ICP-MS. Filtration testing and custom design are free, and you can have up to two samples before committing to an order. What we will ask for in return is the operating data, because we cannot specify against a description.
Manufacturing Scale and Lead Time
30+ production lines and 4,000+ elements a day from a 15,200 m² facility in Shanghai. Factory lead time is 7 to 15 working days depending on series, and that is before freight. Technical support runs from our Miami office in US hours.

Pedimos filtros de grado electrónico para una pequeña tirada y las piezas que recibimos se ajustaban bien a las especificaciones. La comunicación fue sencilla y el plazo de entrega razonable. En general, el proceso fue lo suficientemente fluido para nuestras necesidades.
Preguntas frecuentes
The multi-layer cartridge comes in 10, 20, 30 and 40 inch lengths, which covers standard housings. For a skid or a test loop the PRI and PRS capsules are self-contained at 77 mm and 250 mm outside diameter and need no housing at all. Send the housing model or the part number you run now and we will confirm the interface, end cap and seal before quoting.
Yes. Filtration testing and custom design are free, and you can have up to two samples before committing to an order. For a new formulation we would rather run a trial on your fluid than work from a description, so send the slurry viscosity, solids content and target particle size with the request and we will match elements to it.
Solids content decides it rather than the process step. Slurry loads an element quickly, so the useful measure is differential pressure rather than hours in service. The multi-layer cartridge is rated to 0.3 MPa, and the working approach is to size the filtration area so the changeout lands on a planned stop rather than mid-run. Send your solids content and allowable pressure drop and we will give you an interval.
