We often hear about high-rate batteries, so what exactly are high-rate batteries? Generally speaking, a battery that can support multiple times of its own standard discharge current is called a rate battery. The discharge rate is usually represented by the letter “C”, which is the ratio of the lithium battery’s discharge current to the battery’s nominal capacity. 1C is 1 C-rating, 2C is 2C-rating, and a battery that reaches 10C and above is called a high-rate battery. Taking the PLB IFR26650 2500mAh high-rate battery cell as an example, 1C means that the 2500mAh battery cell is discharged with a current of 2500mA and can be discharged for 1 hour. 2C means that the 2500mAh battery cell is discharged with a current of 2500mA×2=5000mAh and can be discharged for 0.5 hours. Because the battery core supports a maximum current discharge of 50C, the 50C discharge current of the battery is: 2500mA×50=125000mA,…

The 26650 Lithium Iron Phosphate (LiFePO4) battery, also known as IFR26650, is a model specification for cylindrical lithium batteries. The numbers in the model hold specific meanings: “26” represents the battery’s diameter of 26mm, “65” represents its height of 65mm, and “0” denotes its cylindrical shape. The 26650 LiFePO4 battery is primarily used in applications such as UPS batteries, AGV/AMR batteries, medical equipment, lead-acid replacement batteries, communication devices, and energy storage. Structure and Working Principle of 26650 LiFePO4 Battery The 26650 LiFePO4 battery consists of positive electrode material, negative electrode material, electrolyte, separator, and casing. The positive electrode material utilizes LiFePO4, which offers high safety and long cycle life. The negative electrode material employs graphite, which can intercalate and release lithium ions. The electrolyte serves as the medium between the positive and negative electrodes, facilitating the transportation of lithium ions through an organic solvent and salt mixture. The separator, made…

Emergency light batteries, as the name suggests, are batteries that provide power for emergency lighting devices. There are many types of emergency light batteries on the market, including lead-acid batteries, nickel-cadmium batteries, nickel-metal hydride batteries, lithium batteries, etc. Among these batteries, which one is the best? When choosing products such as emergency light batteries, in addition to the quality and safety of the product, you should also consider the life cycle cost of the product, including subsequent  maintenance costs, to avoid frequent replacement in the future that consumes more manpower, material resources, and financial resources . Next, let’s talk about the characteristics of these emergency light batteries. Lead-acid batteries are mainly used in central battery systems . This is also one of the earliest emergency lighting systems. It has certain advantages for installation sites with complex terrain, because all its accessories are connected to one power supply, and subsequent maintenance…

Lithium battery pack aging test is an indispensable procedure in the production process of lithium batteries. It is to better evaluate battery life and performance attenuation, so as to ensure the stability and reliability of factory batteries. What is battery aging test ? The battery aging test is a test that simulates the actual use of the battery, performs charge and discharge cycles on the battery, and records the performance of the battery. This kind of test is generally divided into normal temperature aging and high temperature aging. As the name implies, the battery is placed under normal temperature and high temperature conditions for charge and discharge cycle testing. In the battery aging test, the general test indicators involve the internal resistance, voltage and capacity of the battery, and these data are of great significance for the evaluation of the battery. The purpose of the aging test The purpose of…

Uninterruptible power supplies (UPS) use three primary types of batteries: Nickel-Cadmium, Lead-Acid, and Lithium-Ion, each with its own set of advantages and disadvantages. Let’s start with key characteristics of each battery technology. Nickel-Cadmium (Ni-Cd) batteries: Ni-Cd batteries have a long lifespan（about 20 years design life） and can withstand high temperatures without significant performance degradation, making them a good choice for applications that require high reliability and durability in extreme climate conditions. They also have inherent resistance to overcharging. This means they are less prone to damage caused by overcharging, reducing the risk of performance issues. However, Ni-Cd batteries are relatively expensive. What’s more, the disposal and recycling processes at the end of their service life are extremely costly and have environmental impacts due to the toxicity of nickel and cadmium. Lead-Acid batteries: Lead-Acid batteries have two different types: Valve Regulated Lead Acid（VRLA）and Flooded Lead Acid ( FLA）。 The electrolyte inside VRLA…

If you are struggling to choose which type of battery to use for applications such as UPS/AGV/AMR/lead-acid replacement/solar lights/off-grid solar/startup power, I will recommend the safest option: lithium iron phosphate (LiFePO4) batteries. Why are LiFePO4 batteries safer? Let’s discuss LiFePO4 batteries together. What is a lithium iron phosphate battery? Lithium iron phosphate batteries, also known as LFP batteries, are  lithium-ion batteries with a positive electrode material of lithium iron phosphate and a negative electrode material of carbon. The nominal voltage of a single LiFePO4 cell is 3.2V, and they can be assembled into battery packs with different voltages and currents through various series and parallel configurations. What are the characteristics of lithium iron phosphate batteries? Why are LiFePO4 batteries safer? The safety of LiFePO4 batteries is primarily due to the strong P-O bonds in the LiFePO4 crystal structure, which requires temperatures as high as 600°C to decompose. Compared to other…
