What is the difference between a power-type lithium battery and a capacity-type lithium battery?

The upgrading of the lithium battery industry has driven the technological development of various industries. More and more fields have begun to use lithium batteries as energy sources to power equipment. In these equipment, because of the different application fields, the types of lithium batteries are also divided into power lithium Batteries and capacity lithium batteries, can these two types of lithium batteries be mixed? In addition to the name, what are the main differences between the two lithium batteries? What are the characteristics of power-type lithium batteries and capacity-type lithium batteries? Generally, power-type lithium batteries provide power for the equipment on board. Common application equipment in daily life, such as vehicles, electric vehicles, electric bicycles/motorcycles, golf carts, etc., daily consumer products such as electric tools, and some handheld household appliances. The lithium batteries on these devices are all power batteries. , Power lithium batteries usually need to provide power and energy output for higher-power equipment. Same rationality, smart wearable equipment, UPS backup power supply, 3C digital products. Energy storage power supplies and mobile phone products usually carry batteries that are capacity-type lithium batteries. Such lithium batteries usually do not have high discharge performance, but they can usually provide current within a certain range to maintain operation of the device. The common lithium battery existing in power lithium battery and capacity lithium battery is a battery made of lithium metal or lithium alloy as the negative electrode material and using non-aqueous electrolyte solution. The earliest lithium-ion batteries came from the great inventor Thomas Edison. Due to the very active chemical properties of metal lithium, the environmental requirements for processing, storage and use are very high. So lithium batteries have not been used for a long time. The nominal voltage of lithium battery is generally higher than 3.0 volts, which is more suitable for integrated circuit power supply. Manganese dioxide batteries are widely used in computers, calculators, cameras, watches, etc. What types of batteries are there? Batteries can be divided into lead-acid batteries, primary alkaline batteries, nickel-cadmium batteries, nickel-hydrogen batteries, lithium-ion batteries, etc. The discharge current output of the battery can be divided into power battery and battery. The basic definition of power battery is different. The battery, the battery can have a maximum discharge current of 3 c and power battery usually refers to the ratio of 5 c discharge current and high power battery. 20 c or more discharge current. Generally speaking, lithium batteries are common in power batteries, and there are different types of power batteries. There are lead-acid batteries, nickel-metal hydride batteries, lithium-ion batteries and so on. From the perspective of research and development, what is the difference between power lithium batteries and capacity lithium batteries? 1) Power lithium batteries are designed in accordance with the standards of high-power equipment, whether in the selection of batteries or the development of BMS. Need to select batteries with high-performance discharge characteristics. The wiring harness and BMS have relatively high withstand voltage and overcurrent specifications. All the design ideas are first to meet the basic criteria that can play the maximum performance of the adapted device. 2) The capacity type lithium battery is usually the device does not need high power consumption to operate, stable and continuous small current provides power to the device, and obtains as long as possible Standby time. This is a characteristic of lithium batteries with general capacity. 3) High-end consumer batteries use the most advanced technologies and materials, while power batteries require more advanced process control, consistency control and quality management.
