Key process determining Battery performance, Safety, and Life

JR Energy Solution ensures high-quality electrode production and supply with
a group of highly experienced professionals and the ‘state-of-the-art’ facilities.

01

Mixing Process

The mixing process involves blending anode and cathode active materials, conductive additives, and binders with solvents to create a slurry
02

Coating Process

The coating process involves applying the anode and cathode slurry onto foil to a specified thickness on both sides, followed by drying.
03

Pressing Process

The pressing process involves applying a steady pressure to the coated foil to reduce thickness and increase density.
04

Slitting Process

The slitting process involves cutting the coated foil into a specific width.

Maximization of Efficiency
MES SYSTEM

We build the smart factory system enabling checking and tracking of production data through the MES connected with each production process in real time for maximizing production efficiency and operating the advanced quality management system through the certification of IATF 16949 and ISO 14001.

Production
Process Dashboard

Schematizing the real-time data tracking and analysis by computerizing all processes
Data
Visualization

Sophisticated visualization for the intuitional interpretation and fast analysis of data
Monitoring
of Abnormal Detection

Providing the tool for warning the deviation of the upper and lower management limit levels set for production equipment

QC inspection part

From purchasing raw materials to product development, manufacturing process and product shipment, JRES does Quality Inspection in all process. When the a defective product is detected, relevant department is notified to establish the cause and determine corrective actions. Through the Quality Control Activities, JRES maintains consistent quality with no deviations and standardized specifications.

3D measuring
instrument

An optical measurement device that uses a built-in high-resolution industrial camera to project the measurement object and measure the burr dimensions of electrodes from the transmitted image.

Measurement Process :

In-Process Inspection

Measurement Range :

1 µm and above

Application Range :

Measuring Burr after slitting
Gas
Chromatography

For the measurement of residual NMP within electrodes, the residual NMP is gasified through heating and then passed through a column line to measure the concentration of the detected components.

Measurement Process :

In-Process Inspection / Outgoing Inspection

Measurement Range :

1 Ω ~ 10 MΩ

Application Range :

Measuring residual NMP in electrodes after coating
Tensile Strength &
Cohesion Meter

After importing and inspecting the raw materials Al/Cu required for electrode manufacturing, and going through all the electrode production processes, we sample the produced electrodes to measure tensile strength and adhesion.

Measurement Process :

In-Process Inspection / Outgoing Inspection

Measurement Range :

Tensile Strength : 1000 N (100 kgf)
Adhesion Strength : 10 N (1 kgf)

Application Range :

Foil Import Inspection / Adhesion Strength After Pressing
Karl
Fischer

During the electrode manufacturing process, after coating and drying, residual moisture within the electrode is measured using a temperature and time-based method, with results in PPM units determined by the Karl Fischer titration method.

Measurement Process :

In-Process Inspection / Outgoing Inspection

Measurement Range :

1 ppm ~ 5%

Application Range :

Measuring Active Material and Electrode Moisture
