Why Use The BLU-LDC-04 Wedge Wire Filter?

As we all know, lithium-ion secondary batteries have the characteristics of high energy density, high specific power, good cycle performance, no memory effect, and no pollution.

However, since it uses an organic electrolyte, and the ionic conductivity of the organic electrolyte is about 2 orders of magnitude lower than that of the aqueous solution, in order to ensure good charge-discharge performance under high magnification, the thickness of the electrode sheet is made thin. – Within the sub-millimeter range.

During the coating process, the average particle size of the positive and negative active materials was around 10 μm and 15 μm, respectively.

Therefore, it is required that the active material particles in the slurry do not agglomerate, otherwise, the thickness of the pole piece will fluctuate significantly, reducing the qualified rate of lithium-ion battery products.

At the same time, the agglomerated particles will cause obvious damage to the coating head of the coating machine.

However, in the actual operation process, with the continuous delivery of the slurry, the space left in the electrode slurry storage tank is constantly increasing, so that the degree of volatilization of the solvent increases.

However, there will be more or less residual material on the wall of the storage barrel. After the solvent evaporates, the active material particles will agglomerate, so it is very important to prevent the agglomerated particles from entering the coating head of the coating machine.
In the manufacture or production of lithium-ion batteries, slurries are typically filtered.

However, particle agglomeration still occurs during the coating process after filtration.

Later, a vertical filter was added to the slurry conveying pipe. However, in the actual operation, it was found that the filter was easily blocked and had to be replaced frequently, which not only wasted electrode slurry but also seriously reduced production efficiency.

In order to overcome the above-mentioned shortcomings of the wedge wire filter screen during the transportation of the lithium-ion battery electrode slurry, BLUSLOT provides an anti-blocking filter during transportation of the lithium-ion battery electrode slurry.
