Why does lithium battery pack need aging test?

图片
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 aging test can be mainly explained from two aspects: enterprise and

Three types of UPS batteries, how much do you know？

图片
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 Re

Why are LiFePO4 batteries safer?

图片
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? High Charge/Discharge Efficiency: LiFePO4 batteries have a charge/discharge efficiency of over 90%. High Safety: LiFePO4 batteries are structurally more stable compared to other lithium batt

26650 battery vs 18650 battery, which is better？

图片
  26650 battery and 18650 battery 26650 and 18650 cells are a kind of cylindrical lithium batteries, both are mostly used in ternary lithium, lithium iron phosphate power batteries and have a place in the market. Most of 26650 battery are rechargeable LiFePO4 batteries. While most of 18650 battery are rechargeable ternary lithium batteries. Perhaps you can guess from the “name”，26550 cell is 65 mm in length and 26 mm in diameter. As you can tell from below picture, 18650 cell and 26650 cell have same length of 65mm, but the diameter is shorter, just 18 mm. 26650 battery  vs 18650 battery Performance It is well known that the cell is the foundation of the battery and the performance of the cell is related to the performance of the battery pack. ​Cell performance is determined by many aspects, the most fundamental and most important of which is safety. Safety Compared to ternary lithium-ion batteries, lithium iron phosphate batteries have higher safety because they use lithium iron phosp

What is OEM battery and ODM battery?

图片
In the battery industry, you may often hear about OEM battery and ODM battery, but the meaning and difference between the two may not be understood. Therefore, i will introduce the difference between OEM battery and ODM battery. What is OEM battery? OEM stands for Original Equipment Manufacturer. OEM battery refers to the manufacturer in accordance with the original design to produce processing batteries. At present, this way（phenomenon）is very common, many big brand manufacturers have their own OEM manufacturers, authorizing OEM manufacturers to manufacture and put their own brand label on product to sell it through selling brand value. That not only can reduce the production cost, but also improve the brand added value. What is ODM battery? The ODM stands for Original Design Manufacturer. ODM battery refers to the manufacturer’s design and production of batteries according to the specifications of the original factory. For example, a battery company wants to market a new battery pack
