Introduce the difference between power lithium ion battery, capacity lithium ion battery and consumer lithium ion battery

The difference between power lithium ion battery, capacity lithium ion battery and consumption lithium ion battery. There are many kinds of lithium-ion batteries, such as power lithium-ion batteries, capacity lithium-ion batteries and consumer lithium-ion batteries. Power lithium-ion batteries and capacity lithium-ion batteries are different in the use of materials and production processes, and the difference in discharge characteristics means that the application fields of the two are very different. When choosing a lithium-ion battery pack, the two should be clearly distinguished to avoid adverse effects on the load. The difference between power lithium-ion battery and capacity lithium-ion battery Li-ion battery pack refers to the power supply for power tools, and now refers to the lithium-ion battery pack that supplies power for electric cars, electric trains, etc. Power and energy lithium-ion battery packs are accompanied by the emergence of plug-in hybrid vehicles. It needs the battery to store a large amount of energy, can support a series of pure electric drives, and has good power characteristics, and enters the hybrid mode when the battery is low. Power lithium-ion battery. JPG1. Different voltages In the battery industry, when the voltage increases, the corresponding output voltage will also increase, so that the power lithium-ion battery pack can meet some high-power equipment; the direct use of parallel connection is to increase the current of the entire battery, Its capacity is affected by the output current. Therefore, the direct use of parallel connection is to increase the capacity of lithium-ion batteries. The capacity of the battery connected in this way is usually relatively large, which is the so-called capacitive lithium-ion battery. 2. Use different products. Some large-scale equipment requires high voltage values. Because low-power battery packs cannot operate, we have to choose power lithium-ion batteries. For example, the electric bicycle we often use, its voltage value is often 48V, related to some of our lives, 48V is not small. So you must use lithium-ion batteries to keep the bike running. The capacitive lithium-ion battery requires endurance and high capacity just like mountain running to maintain long-term low-power discharge. Usually used for low-current discharge, but large-capacity products, such as mobile power supplies, outdoor flashlights, etc. 3. Different internal resistance The internal resistance of the power lithium-ion battery is smaller than that of the capacity lithium-ion battery. Take 18650 as an example, a good three-discharge manufacturer usually has a PDC, and the internal resistance is about 40. A 5-rate discharge generally does not have a PDC internal resistance of about 20. 4. Different discharge characteristics Li-ion battery packs are characterized by current discharge Large, the discharge rate is generally above the market C, which can achieve instantaneous high current; capacitive lithium-ion batteries have the characteristics of small discharge current, large capacity, and long-term stable power supply. How to distinguish between power lithium ion battery pack and capacity lithium ion battery? That is, composite material power lithium ion battery pack is mainly composed of positive and negative electrode materials, and its size is smaller than that of capacitive lithium ion batteries. The energy density is not large, and the diaphragm material and electrolyte have good conductivity and good conductivity. Second, the current large and small power lithium-ion battery packs have more lug materials in the positive and negative electrodes than capacitor lithium-ion batteries (reducing the internal resistance of the lugs to meet larger currents). 3. Discharge multiplier power lithium ion battery pack supports high current discharge, up to 30C current, while 18650 ordinary lithium ion battery only supports 1C discharge. Lithium-ion battery consumption introduction As consumer electronics products enter the stock market, the rise of consumer-grade lithium-ion batteries may slow down. In general, as the global consumer electronics market becomes saturated, the share of demand for lithium-ion batteries will decline. The report predicts that by 2020, the demand for lithium-ion batteries for consumer electronics will drop to 30.5%. Other emerging markets, especially electric vehicles and energy storage, will see their share of demand rebound sharply. As the rising rate of consumer electronic products slows, consumer lithium-ion batteries may usher in a reshuffle. Some products with poor quality and low safety factor have been eliminated. Companies with technological accumulation and capabilities and scale advantages will have new opportunities. Consumer-grade lithium-ion batteries do not need long-term reliability, and generally do not use them alone, so they do not require high consistency.
