Which is better for dynamic batteries and lithium iron phosphate batteries?
Sanyo material lithium battery may replace the lithium iron phosphate battery and become automotive power The mainstream trend of battery development. In actual use, lithium iron phosphate batteries have the advantages of high temperature resistance, strong safety and stability, cheap price, and better circulation performance. Compared with ternary lithium batteries, lithium iron phosphate batteries are more advantageous in terms of stability. However, the car market is large and the application scenarios are diverse. More commercial vehicles and trucks will use lithium iron phosphate batteries, and passenger cars and cars will be biased towards ternary lithium batteries.
Lithium iron phosphate batteries are the most important part of new energy industries such as electric vehicles, electric bicycles, and energy storage, which play a key role in further promoting and enhancing the technical level of enterprises. However, in recent years The rapid development of lithium battery technology has brought a certain impact to the industry of the lithium battery. Sanyo lithium batteries may replace lithium iron phosphate batteries and become the mainstream trend of automotive power batteries.
Lithium iron phosphate battery:
refers to lithium ion batteries using lithium iron phosphate as a positive electrode material. The characteristics of this type of battery are not valuable metal elements (such as cobalt, etc.). Because the cost of lithium iron phosphate batteries does not contain valuable metal materials, the cost of lithium iron phosphate can be compressed very low. In actual use, lithium iron phosphate batteries have the advantages of high temperature resistance, strong safety and stability, cheap price, and better circulation performance.
Sanyo lithium battery:
refers to the use of lithium nickel cobalt manganate as a positive electrode material, graphite as a lithium battery for negative electrode materials. Unlike lithium iron phosphate, the three -dollar lithium battery voltage platform is very high, which means that at the same volume or weight, the comparison energy and power of the ternary lithium battery is larger. In addition, the ternary lithium battery also has great advantages in terms of high -rate charging and low temperature resistance.
Is it better to choose a lithium iron phosphate battery in power batteries or a ternary lithium battery?
At present, domestic power batteries are mainly divided into two factions. According to different positive materials, they are divided into lithium iron phosphates. And Sanyuan Materials School. Xiaobian thinks that in the future, the power battery will still choose lithium iron phosphate batteries.
① In terms of technical routes, more and more extended range electric vehicles began to use lithium iron phosphate batteries, which can not only improve the safety of the vehicle, but also reduce the cost of the entire vehicle manufacturing, help the extension electric vehicle Expand the share in the new energy vehicle market. For example, the battery capacity of 25AH and a voltage of 48V, the minimum market quotation of lithium iron phosphate batteries and ternary lithium batteries is generally 1020 yuan and 1210 yuan.
② In terms of energy storage market, thanks to some power battery companies to start layout energy storage business, the market demand of lithium iron phosphate has begun to expand. According to the international market research institution GTMResearch's energy storage report shows that the decline in lithium battery prices declined slowly in 2018, but the application of China's power grid -side energy storage project has continued to increase the amount of lithium iron phosphate batteries.
③ On the other hand, with the continuous improvement of technology, the energy density of some lithium iron phosphate batteries has reached the level of the ternary NCM523 (the mainstream NCM523 battery energy density is 160-200Wh/kg), which is basically basically basically). Get the highest request for subsidies. Compared with ternary lithium batteries, lithium iron phosphate batteries are more advantageous in terms of stability.
④ The last is a significant decline in subsidies. The reason why lithium iron phosphate has low risk in terms of supply and price of raw materials is that it is not necessary to use valuable metals such as cobalt. Reduce cost pressure to a certain extent.
The ternary lithium battery is more suitable for household electric vehicles:
① Different from large electric buses, the space is always the first. Lithium iron phosphate batteries with low energy density will occupy the uncomfortable car space, and due to the heavier quality, the battery life of discharge during use will also be greatly affected. Relatively speaking, the ternary lithium battery with higher energy density also saves room for household cars while solving the problem of weight.
② In addition to battery life, charging is also an important link of electric vehicles in actual use, while the ternary lithium battery has a very large advantage in charging efficiency than the lithium iron phosphate battery. At present, the more common charging methods on the market are constant streaming and constant voltage charging. Generally, constant current charging is used at the beginning of the charging. At this time, the current is large and the charging efficiency is relatively high. After the voltage reaches a certain value, the reduction of the current to constant voltage charging, which can make the battery fill more.
③ enough safe materials and craftsmanship, the most harmful part of traditional internal combustion engine cars is fuel containing huge energy, liquid fuels such as gasoline and low -explosive liquid fuels. Essence For new energy vehicles, the dynamic ternary lithium battery, after a comprehensive battery management system (BMS) monitoring, each battery can be controlled the most accurate control to prevent accidents.
Lithium iron phosphate batteries are the best battery that recognizes the best safety performance; second, the battery capacity is large and the energy ratio is higher; due to the small internal resistance of the battery, the battery can also directly reduce the heating of the battery. Lithium iron phosphate batteries and ternary material batteries are the two major paths of power lithium batteries used in new energy vehicles. The former is used in most domestic new energy vehicles, while the latter is used in Tesla and other models.
Comprehensive: factors such as the safety, life, battery's own performance of lithium iron phosphate battery, and the characteristics of the three yuan lithium batteries in high energy ratio, in the future Competition will continue and become more and more hot.
Lithium iron phosphate battery and andComparison of ternary lithium batteries:
⒈ Energy density comparison
Lithium iron phosphate battery monomer, energy density is 120Wh/kg, after group group 80Wh/kg The energy density is 180Wh/kg, and the energy density is 110Wh/kg after the group. From the perspective of data, in terms of energy density, ternary lithium batteries are better than lithium iron phosphate batteries.
性 Safety
Tri- lithium battery liquid electrolyte, flammable and explosive, easily triggers \u0026 ldquo; heat out of control \u0026 rdquo; It is easy to pierce the diaphragm, causing short circuits of batteries, causing hidden safety hazards. The lithium iron phosphate battery has the advantages of high temperature resistance, strong safety and stability, and better circulation performance in actual use.
In terms of cost
Because lithium iron phosphate batteries do not contain valuable metal materials, the cost of raw materials can be compressed very low. The ternary lithium battery uses lithium nickel cobalt manganate as the positive electrode material, and graphite is used as a lithium battery for the negative electrode material, so the cost will be much more expensive than the lithium iron phosphate battery.
领 Application field
According to data from the Ministry of Database of the Tram Exchange Database, the battery of new energy passenger cars is mainly lithium iron phosphate batteries, and passenger cars using lithium manganate batteries also account for relatively high Due to its advantages, the metalized lithium battery has become the first choice for passenger cars.
Power battery selection of lithium iron phosphate batteries is better or ternary lithium battery. Xiaobian is introduced here first. No matter what, the technology does not distinguish between good or bad. Battery products. However, the car market is large and the application scenarios are diverse. More commercial vehicles and trucks will use lithium iron phosphate batteries, and passenger cars and cars will be biased towards ternary lithium batteries.
