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…
In lithium-ion batteries, although the electrolyte does not directly store energy, it profoundly influences energy density, rate capability, cycle life, and safety. It can be regarded as the “circulatory system” connecting the cathode and anode. The performance of the electrolyte directly determines whether a battery can operate stably, efficiently, and over the long term. I….
In lithium-ion batteries, the role of the anode material is often underestimated. Many people focus more on how high the energy density of the cathode is, but in reality, the cycle life, safety, rate capability, and even the initial coulombic efficiency of a battery are all closely related to the anode material. A wide variety…
Cathode materials are one of the key factors determining battery performance. Whether a battery has high energy density, good safety, or long cycle life is, to a large extent, directly related to the choice of cathode material. At present, mainstream lithium-ion battery cathode materials can generally be divided into several major categories: layered oxides, spinel-structured…
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…
I. Proposal of the Lithium-Ion Battery Concept and Early Exploration In modern battery technology, the lithium-ion battery is widely regarded as a truly revolutionary invention. The choice of lithium as the core element of this battery system is primarily attributed to its unique physical and chemical properties. Lithium is the lightest metal found in nature…
If one were to look through the periodic table for a metal that is “naturally suited” for batteries, lithium would almost certainly rank first. It is the lightest metal element found in nature and possesses an extremely low standard electrode potential (–3.045 V vs. SHE). The combination of these two properties gives lithium an exceptionally…
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…
