Product Features

Product Parameters

Production data acquisition

Collecting data and status information during the current running process. This can include information such as job status, production metrics like quantity, volume, weight, quality data, and so on.
System integration technology

The process of comprehensively integrating various components, subsystems, and sub-systems from different sources, using scientific methods and technology, to create an organic, efficient, unified, and optimized system in accordance with the requirements for best performance.
Tracing

The activity of providing organizational records of resource and product usage, using tracking information to trace backward or forward from any point.
Overhang precision

The range of variation in the difference between the envelope lines on the same side of the positive and negative electrode sheets within the core pack is referred to as "EU" (Envelope Uniformity).
Alignment precision between separator and electrodes

The alignment degree between the separator and the positive or negative electrode within the core pack is referred to as "FU" (Alignment Uniformity).
Jellyroll alignment metric

The relative position difference within the core pack between electrode sheets and electrode sheets, as well as between electrode sheets and the separator, where they overlap.
Rolls alignment metric

The relative position error in the overlap of material rolls (positive electrode sheets, negative electrode sheets, separators, tapes).
Auricular alignment metric

The relative position error in the overlap of multiple tab or tab-like features within the core pack.
Overhang

The part of the negative electrode sheet that extends beyond the positive electrode sheet in either the length or width direction.
Viscosity

A characteristic of slurry material flow that reflects the strength of interactions between liquid molecules during motion. Strong interactions (high viscosity) result in less flow.Note: The viscosity typically referred to is shear viscosity.
Burr

Sharp metal impurities present at the edges of electrode sheets can potentially puncture the separator, leading to a short circuit inside the battery.
Particle size

The size of particles in a slurry is referred to as particle size or particle granularity.
Solid content

The solid content of a slurry is essentially the non-volatile content of the slurry. The testing procedure involves heating at a specific temperature to determine the time, and then measuring the remaining substance's weight in relation to the initial substance's weight. There are two testing methods: infrared and oven-drying.
Surface density

After the electrode has undergone the coating process, the weight of the electrode material applied per unit area is referred to as areal mass loading.
Compacted density

After the electrode has undergone the calendaring process, the weight of the electrode material applied per unit volume is referred to as volumetric mass loading.
Dry coating thickness tolerance

The uniformity tolerance of the thickness of the coated material on a web after drying is categorized based on the coating process into single-side dry thickness tolerance and double-side dry thickness tolerance, depending on whether it is a single-sided or double-sided coating.
Yield rate

When the raw materials are qualified, the percentage of output products that meet the requirements after testing, in relation to the theoretical total number of products that can be produced from the input materials.
Line yield

The percentage of the number of produced cells in relation to the number of input cells.
Test pass yield

The percentage of the number of qualified tested cells in relation to the total number of produced cells.Note: Qualified tested cell count refers to cells that, after formation, meet the battery parameter requirements for capacity, voltage, internal resistance, and self-discharge.
Pair pass yield

The percentage of paired cells in relation to the total number of qualified cells.Note: Paired cell count refers to cells that meet the requirements for grouping and pairing, indicating the number of cells falling within the specified range for pairing, mainly concerning capacity, internal resistance, and self-discharge. This primarily assesses the consistency of cells and can be expressed using the sigma values for capacity, internal resistance, and self-discharge.
First pass yield of cell

The percentage of qualified cells that have successfully passed all tests from the first process to the last process in the cell production process, in relation to the total number of input cells.
Yield of cell

The percentage of cells that meet the requirements for grouping and pairing in relation to the initial input of cells in the production of cells.
Material utilization

The translation of the provided text is: "Material utilization rate refers to the proportion of the quantity (price) of materials included in qualified products to the total consumption of materials (raw materials), i.e., the percentage of materials that have been effectively utilized out of the actual consumption."
Process material utilization

In each step of the battery manufacturing process, the proportion of the quantity of materials included in the qualified products to the total consumption of raw materials for that step is the material utilization rate. It represents the percentage of materials that have been effectively utilized in that step out of the actual consumption of materials.
