What is electrode overlap and why does it matter? In lithium-ion cell manufacturing, electrode overlap refers to the region where the active areas of the anode and cathode are aligned across the separator as shown in Figure 1. Maintaining adequate overlap, whereby the anode active area overlaps the cathode, is critical to achieving uniform current … Read more
When comparing slitting methods it is important to consider: Goebel Type This is a cutting method in which the upper knife is fixed in the cutting position in advance, and the entire shaft is moved sideways by a specified amount of air pressure to bring it into contact with the lower knife. The thickness of … Read more
Learn how professional lithium battery manufacturers ensure pack Learn how professional lithium battery manufacturers ensure pack reliability through pre-assembly cell testing, voltage and internal resistance matching, and accurate sorting. Discover why these steps are essential for safe, long-lasting battery packs. Cylindrical Battery Cell Testing and Matching: The Essential Process Behind Reliable Lithium Battery Packs Author: … Read more
In order to reduce costs in the cell manufacturing process the electrodes are coated in widths far greater than any battery cell would use. Hence, after coating, drying and calendering it is necessary to cut the electrodes length wise into a usable width. It is really important that the resultant edges are cut cleanly, without … Read more
Burrs and wavy edges on cell electrodes can have serious consequences up to and including an internal short-circuit and thermal runaway. Hence it is important to understand the slitting process and under what conditions burrs and waviness occurs. Slitter Cutting Control Parameters There are basically three slitter cutting control parameters for the shear cut method, … Read more
There are basically three slitter cutting control parameters for the shear cut method, which uses the same principle as scissors. These three factors can be controlled manually or automatically. Maysun Corporation was established based on a Paper-making company in 1967. So we see from perspective of Paper-making manufacturers and have developed technology which they require … Read more
Author: Glimpse Poor battery quality can lead to major safety and reliability issues in the field in applications including consumer electronics[1, 2], electric vehicles [3, 4], aviation [5], and more. However, detecting latent cell defects—which are responsible for these battery quality issues—during production is notoriously challenging. In this post, we evaluate the primary techniques used in … Read more
Author: Glimpse Battery defects are a major scourge on the industry. In fact, battery defects have been deemed responsible for major billion-dollar electric vehicle recalls.1 Furthermore, dozens of battery safety incidents have been attributed to poor-quality and/or counterfeit batteries, which often have poor performance, reliability, and safety.2–6 In short, battery defects directly threaten both the … Read more
