Battery Technology

Lithium-ion batteries have found their way into almost every corner of our daily lives: smartphones, tablets, Bluetooth earphones, drones, power tools, new energy vehicles, and energy storage systems. At the same time, news reports about lithium battery fires and explosions appear from time to time, raising a common concern: Are lithium-ion batteries really safe?Where do…

Lithium-ion batteries are almost everywhere—from smartphones and tablets to electric vehicles and energy storage systems, they make our lives more convenient. But do you know how this tiny battery works inside? In fact, its principle is both interesting and scientific. A lithium-ion battery mainly consists of a positive electrode, a negative electrode, an electrolyte, and…

In the fields of energy storage and new energy vehicles, you often hear the names “Lithium Iron Phosphate (LiFePO4)” and “Ternary Lithium (NCM/NCA).” Although both are lithium-ion batteries, their application scenarios and performance characteristics are quite different. Today, we’ll provide a systematic overview to help you easily understand the advantages and suitable use cases of…

In the battery industry, “C-rate” is almost an unavoidable technical term. Whether you are reading a battery datasheet, discussing a product solution, or evaluating an energy storage or power project, you will frequently hear expressions such as 0.5C, 1C, or 3C. In reality, however, many people use this term every day without fully understanding what…

When it comes to battery capacity, we almost always encounter two units:one is mAh, commonly seen in consumer electronics like smartphones,and the other is kWh, or even MWh, frequently mentioned in energy storage systems and electric vehicles. They both describe batteries, so why do consumer electronics use mAh, while energy storage systems almost exclusively talk…

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…

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…
