Rotary Shaft Seals for Lithium-Ion Battery Slurry Mixing

Rotary shaft seals play a critical role in lithium-ion battery production. In industrial mixers, any amount of slurry that leaks past the radial shaft can be costly and dangerous. Our uniquely suited rotary shaft seals eliminate the risk of leaks, resulting in reduced maintenance, elimination of shaft wear, reduced downtime, and the lowest total cost of operation.

To create vehicles with with increasingly longer range, innovations in the cathode powder industry are moving toward solid-state powder-composite batteries with much thicker electrode structures and much higher capacity as a result.

Lithium-ion battery producers know the importance of operational efficiency, especially when it comes to cathode and anode slurry mixing. That’s why they choose CinchSeal rotary shaft seals to keep product where it should be.

Issues Solved

Premature Bearing Failure

  • Self-adjusting design prevents contamination build-up in bearing housing
  • Self-lubricating seal enables dry-running operation, decreasing wear and tear

Battery Powder Leakage

  • Air barrier created by purging prevents product from entering the seal
  • Rotating faces push outward against stationary faces for a tighter seal
  • Cooling of rotating seal faces reduces friction-generated heat, prolonging useful life of the seal

Shaft Damage

  • Eliminate damage from friction with an elastomer that spins with the shaft
  • Tolerates shaft misalignment up to ¼ inch (common in bulk-handling equipment) without losing its seal

Environment Contamination

Stop product leakage and environmental contamination with:

  • Larger shaft/seal interface surface
  • FDA-approved silicon elastomer and PTFE rotor cups

Preparing for Increased Powder Demand

With cathode powder demand expected to surge, one often overlooked concern for manufacturers is mixer leakage due to seal issues. Mixer malfunctions pose risks to personnel and the environment, and can incur substantial time and financial losses. Proactive evaluation and enhancement of mixer seals are imperative. Installing CinchSeal rotary shaft seals ensures sustained efficiency in mixer and blender operation.

Why CinchSeal Rotary Shaft Seals?

In chemical plants, mixer and blender failures happen for several
reasons, but the main causes include:

  • Premature bearing failure
  • Irreversible damage to shafts
  • Expensive battery powder leakage
  • Toxic environment contamination

Less Maintenance, Fewer Replacements

CinchSeal rotary shaft seals last longer. They need less maintenance, which means time and cost savings. And they don’t have to be replaced as often. When it is necessary, only internal parts – elastomer and rotor cups – need to be replaced. Changing them out is also a simple process.

This simplicity is especially evident in CinchSeal split rotary shaft seals made for harsh environments, like those found in chemical plants. Split seals offer a number of advantages:

  • Stainless steel that stands up to harsh working conditions
  • Split rotary shaft seals that make conversion and installation easy
  • Easy disassembly to make batch and frequent cleanings a breeze
