In the battery manufacturing process, aging testing is a critical step to ensure product quality and safety. However, when customers learn about battery production, a common question often arises: What is the difference between cell aging and PACK aging? Are both really necessary? In fact, cell aging and PACK aging focus on different aspects. They…
In the manufacturing process of lithium batteries, aging testing is an indispensable and critical step before shipment. It is not simply a matter of “repeated charging and discharging,” but rather a comprehensive verification of battery performance stability, safety, and reliability by simulating real-world operating conditions. A lithium battery that has not undergone sufficient aging testing…
In the battery industry, the mixing process may look simple. But once you actually step into the slurry-preparation workshop, you’ll realize that very few people truly understand how mixing should be done. Many operators have worked for years, even more than a decade, yet their procedures remain unchanged, following old habits. They never stop to…
In lithium-ion battery R&D and manufacturing, people tend to focus their attention on the design parameters themselves—such as areal density, thickness, baking time, and so on.However, any process intended for mass production must include one crucial factor that is often overlooked: tolerance. Tolerance may seem insignificant, but it is the most important criterion for determining…
How long can the cycle life of a lithium-ion battery actually reach? Is it 300 cycles, 500 cycles, or over a thousand cycles? This is a fundamental question that every professional in battery R&D, quality, manufacturing, and sales must face. The cycle performance of a battery depends not only on the materials themselves, but also…
When a lithium-ion battery has insufficient electrolyte, it’s just like a person getting sick—minor issues may seem harmless, but severe ones can directly threaten its “life.” So what exactly happens to cell performance when electrolyte is lacking? What’s the difference between a slight shortage and a severe shortage? In this article, the editor from Iray…
In the battery industry, “low voltage” is an issue that every engineer and salesperson has to face. Customers often complain: “These batteries dropped in voltage after sitting for a while — is there something wrong with your cells?” In fact, in most cases, the root cause of low voltage is excessive self-discharge of the battery….
When people hear “Six Sigma,” the first reaction is often: “Isn’t that Motorola’s famous quality management method?” That’s right — Six Sigma was originally created to improve product quality and reduce defects. But later, people found that it could do far more: lower costs, increase efficiency, analyze supplier performance — it has spread into every…
Capacity is one of the most critical performance indicators of lithium-ion batteries. Whether during sample validation or mass production, low capacity is one of the most troublesome problems. However, the causes of low capacity are often not singular—it usually results from a combination of factors involving design, material selection, process, operation, and testing.This article introduces…
In the field of battery R&D, the process is filled with the art of opposition and balance. Just as yin and yang coexist and depend on each other in nature, numerous parameters within a battery system often stand in opposition and mutual constraint. Energy and safety, capacity and lifespan, efficiency and yield — these conflicting…
