Mixing
During mixing, the active materials, lead additives, solvents and binders are combined to form an electrode paste called a slurry. Mixing and dispersing are carried out in a stainless steel tank with a stirring tool.
Condition monitoring of the air supply
Ensuring air quality in the clean room
Particle impurities in clean room environments can lead to quality defects. Failure of the air supply fan can lead to impurities in the form of dust and other extraneous particles. ifm solutions for vibration monitoring can provide indications of critical device failures weeks in advance. This contributes to ensuring quality in the electrode lubrication process and improving system availability.
Ensuring system availability
Quality assurance
Solution
Condition-based maintenance based on actual needs is possible thanks to continuous diagnostics. This cuts costs compared to time-based maintenance intervals. Early detection by means of vibration diagnostics and channel speed monitoring on rolling bearings detects motor damage promptly before it progresses. This makes it possible to prevent unplanned downtimes.

Condition monitoring of the mixer
Preventing a machine failure
A machine failure can lead to loss of production material for the battery slurry. Rotating components like bearings may fail for various reasons including overload and friction, etc. By using ifm vibration solutions for your mixing systems, you can increase system availability, maintain process throughput and minimise material loss.

Temperature monitoring of the slurry
Maintaining the correct temperature of the slurry in the mixing process
In addition to rotational speed, temperature is another important parameter in the mixing process. This significantly affects viscosity, which is the crucial parameter for the quality of the slurry and the coated carrier foil in the following process step. Temperature sensors can drift over the course of time. If this is not detected, it can lead to improper processing temperatures and resulting quality problems.

Quality assurance
Solutions
IO-Link temperature sensors from ifm transfer the measured values entirely in digital format. Transformation processes that can lead to inaccuracies are eliminated. The TCC temperature sensor also performs self-checks to ensure its measuring accuracy. If the sensor detects a drift, it indicates this immediately, thereby ensuring process quality between the calibration intervals.

Valve monitoring
Ensuring error-free functionality of valves
In process technology where liquids, air or gases are used, valves are needed for dosing and control. Seals inside quarter-turn valves become damaged over time. Accumulations of material can prevent a valve from closing and opening properly. The result is reduced process efficiency and reliable operation is adversely affected.

Enhancing performance
Solution
MVQ quarter-turn valve sensors detect even the slightest blockages as well as wear on the valve seal, which in turn allows for condition-based planned maintenance. Costly unplanned downtimes are prevented.

Level monitoring of ingredients
Enabling the supply of raw materials without interruptions
A suitable quantity of raw materials and components relevant to production must always be kept in reserve to ensure a smooth production process without interruptions. On the other hand, overfilled tanks can lead to loss of products, which also results in financial losses. Monitoring of levels and limit states reliably prevents storage tanks from becoming empty or overfilled.

Quality assurance
Solution
LMT sensors use capacitive high-frequency technology to reliably detect full tank conditions and to prevent tanks from being overfilled and wasting products. The sensor is also insensitive to build-up and has a high protection rating of IP 68 / IP 69K. With level sensors type LR, the level in tanks can be exactly and continuously monitored by means of a directed microwave.

Level monitoring of solvents
Improving reliability with level monitoring
Maintaining the tank fill level is critically important in production operation to ensure that the process runs smoothly and there are no rejects due to lack of material.

Solution
ifm's hydrostatic level sensors are mounted starting from the bottom of the tank to ensure an exact continuous level of the working material and prevent dry conditions. The sturdy stainless steel design of the PI product family with flush design is suitable for aggressive media.
