Lithium-ion batteries: Quality control in the coating of anodes and cathodes

Why is this important?

High-performance product battery

Batteries are inconspicuous companions in everyday life, but are now indispensable. Batteries are high-tech products that are subject to high demands. This starts with the coating of the anodes and cathodes. The electrodes ensure that the ‘battery principle’ works at all. Only a high-quality, flawless electrode coating ensures that the battery functions properly. Quality control is therefore essential.

Closed-loop control of the coating

Measuring devices in dry and wet coating enable detailed process analyses through same-spot measurement. Dynamic adjustment correction using depth self-learning creates a data basis that can be used for both manual and automatic control (closed-loop control).

 

Reasons for the importance of quality control

Battery performance

  • Homogeneous coating: Uniform charge distribution for maximum efficiency.
  • Defect prevention: Early detection of cracks and uneven layers.

Battery safety

  • Short-circuit prevention: Avoidance of overheating and explosions.
  • Electrode stability: Mechanical stability for increased safety.

Battery life

  • Degradation reduction: Extended service life thanks to high-quality coating.
  • Capacity retention: Long-term performance without loss of capacity.

Quality control maximises efficiency, safety and battery life. A must for top products!
The Mahlo/Reechi quality control systems have been specially designed for electrode production and take your coating to a new level!
