Lithium battery industry upgrade, led to the development of technology in various industries, more and more areas began to use lithium batteries as energy to power equipment, in these devices, because of the different applications, lithium battery types are also divided into power lithium batteries and capacity lithium batteries, whether these two types of lithium batteries can be mixed? In addition to the name of the two types of lithium batteries, what are the main differences in other aspects?
What are the characteristics of power lithium battery and capacity lithium battery respectively?
In general power lithium battery is to provide power energy for the equipment carried. Common applications in daily life such as transportation, electric cars, electric bicycles / motorcycles, golf carts, etc., daily consumer products such as power tools, some handheld household appliances, these devices are equipped with lithium batteries are power cells, power lithium batteries usually need to provide power energy output to larger power devices. The same reason, smart wearable devices, UPS backup power, 3C digital products. Energy storage power, cell phone products usually carry the battery belongs to the capacity lithium battery, this type of lithium battery usually does not have a very high discharge performance, but can usually provide current to maintain the operation of the device within a certain range.
Commonalities between power and capacity lithium batteries
Lithium battery is a kind of battery made of lithium metal or lithium alloy as the anode material, using a non-aqueous electrolyte solution. The earliest lithium-ion batteries came from the great inventor Thomas Edison.
Because lithium metal has very active chemical properties, the processing, preservation and use of the environment is very demanding. So lithium batteries have not been used for a long time.
The nominal voltage of lithium batteries is generally higher than 3.0 volts, which is more suitable for powering integrated circuits. Manganese dioxide batteries, widely used in computers, calculators, cameras, watches, etc.
What kinds 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 size of the discharge current output of the battery can be divided into power battery and battery, the basic definition of power battery is different, battery, battery can be the maximum 3 c discharge current and power battery is usually referred to 5 c discharge current and high power battery than in 20 c or more discharge current.
Generally speaking power batteries are common in lithium batteries, there are also different types of power batteries. There are lead-acid batteries, nickel-hydrogen batteries, lithium-ion batteries, etc.
From the perspective of research and development, what is the difference between power lithium battery and capacity lithium battery?
(1) power lithium batteries, whether in the selection of cells, or the development of BMS, are designed in accordance with the standards of high-power devices, first of all, the cells need to be selected with high-performance discharge characteristics of the cells. Wiring harness, BMS voltage overcurrent specifications are relatively high. All the design ideas are first to meet the maximum performance of the adapted equipment as the basic standard
(2) capacity lithium battery is usually equipment does not require high power operation, stable and continuous small current to provide power to the device, as long as possible to obtain a longer standby time. This is the characteristics of the general capacity lithium battery has.
3) High-end consumer batteries use the most advanced technology and materials, while power batteries require more advanced process control, consistency control and quality management.
