Overview
In modern battery manufacturing, precision and consistency are paramount. Moisture and thickness variations can dramatically affect conductivity, performance, and safety. MoistTech’s IR-3000 Series Near-Infrared (NIR) Sensor delivers real-time, non-contact, and highly accurate measurements of both moisture and thickness in battery paste and separator films, enabling manufacturers to achieve superior control and efficiency.
PROCESS SIGNIFICANCE
Battery separator films are thin, micro-porous layers that serve as insulators between the anode and cathode—critical to both performance and safety. Consistent film thickness and porosity are essential for:
-
Stable electrochemical performance
-
Reduced risk of short circuits
-
Optimized ion flow and energy density
-
Improved cell longevity and efficiency
Battery pastes also demand precise moisture control, as improper drying can lead to cracking, poor adhesion, or inconsistent electrode performance. By integrating continuous NIR measurement, manufacturers can instantly detect out-of-spec conditions and correct them before defects occur.

Understand the Process
The 3000 Series provides continuous, reliable readings and is a one-time calibration, maintenance free, drift free optical design allowing for immediate process adjustments based on real-time measurements.
RECOMMENDED MEASUREMENT LOCATIONS
The MoistTech IR-3000 represents the industry’s most robust and maintenance-free solution for battery paste and film monitoring. Designed to operate in extreme manufacturing environments, it features:
-
Simultaneous moisture and thickness measurement
-
Continuous, drift-free operation for long-term stability
-
One-time calibration — no routine recalibration required
-
Real-time data output to plant control systems for instant adjustments
-
Digital filtering and averaging for highly stable readings
The IR-3000 sensors can be mounted above belts, conveyors, or film lines to continuously scan material flow. Common installation points include:
-
Post-Coating / Pre-Dryer Stage – Monitoring wet paste thickness and solvent moisture
-
Post-Dryer / Pre-Rolling – Ensuring uniform drying and binder distribution
-
Final Film / Separator Roll Stage – Verifying thickness and residual moisture before slitting or lamination
Measurement data is displayed on an external interface or integrated PC, allowing for automated or manual process control.
