Which has a longer real life, lithium ternary or lithium iron phosphate? Lithium iron phosphate battery pack and ternary lithium battery which has a longer life? Lithium-ion batteries are divided into two types of ternary lithium batteries and lithium iron phosphate batteries, lithium iron phosphate pack cycle 5000 times remaining capacity 84%, ternary lithium batteries cycle 3900 times remaining capacity 66%, cycle life for comparison, lithium iron phosphate pack advantage is more obvious. Today we will talk about the lithium iron phosphate and ternary lithium batteries who have a longer real life.
Lithium iron phosphate battery: refers to the lithium-ion battery with lithium iron phosphate as the cathode material. This type of battery is characterized by the absence of precious metal elements (such as cobalt, etc.). Due to the absence of precious metal materials, lithium iron phosphate battery pack raw material costs can be compressed to very low. In actual use, lithium iron phosphate batteries have the advantages of high temperature resistance, high safety stability, cheap, and better cycle performance.
Ternary lithium battery: refers to the use of lithium nickel cobalt manganate as the cathode material, graphite as the negative electrode material of lithium batteries. Different from lithium iron phosphate, ternary lithium battery voltage platform is very high, which means that in the same volume or weight, ternary lithium battery specific energy, specific power is greater. In addition, in terms of large multiplier charging, and low temperature resistance, ternary lithium batteries also have great advantages.
As a rechargeable lithium battery, ternary lithium battery output voltage stability, high output voltage, stable performance, high capacity, long service life, wide operating temperature range, good safety and environmental protection, so the future of lithium battery development on the road has a lot of upside, but still need to continue to research in order to improve their own defects.
Trithium and lithium iron phosphate battery real life which is long?
If the remaining capacity / initial capacity = 80% as the end of the test point, the current lithium iron phosphate laboratory 1C cycle life of more than 3500 times, part of the 5000 times, while the ternary lithium battery laboratory 1C cycle life of about 2500 times. In the cycle is really life at this point, lithium iron phosphate packs compared to ternary lithium batteries, the real life is much longer. In the same number of cycles, the residual capacity of lithium iron phosphate battery is also much more than the ternary lithium battery.
Ternary lithium battery cycle 3900 times the remaining capacity of 66%, lithium iron phosphate battery cycle 5000 times the remaining capacity of 84%, cycle life than ternary material lithium battery, lithium iron phosphate battery advantage is obvious.
Theoretically speaking, the life of ternary lithium batteries is 2000 charge and discharge cycles, we count as a day a charge, can also last more than 5 years. However, the actual use and theory is still a difference, if 1000 charge and discharge cycles, in essence, ternary lithium batteries have decayed by 50%, that is, fully charged can only run half of the original mileage.
Ternary lithium battery and lithium iron phosphate battery which has a long life?
Lithium iron phosphate battery quality is better, the first year of decay can be controlled within 5%, the second year can be within 15%. Ternary lithium battery type, the first year of decline in 7-10%, the second year in 20-25%. Of course, the specific and the use of load, the frequency of use has a relationship, here is only a general statement.
Lithium iron phosphate packs than lead-acid batteries and ternary lithium batteries have a long cycle life. Lead-acid batteries in the "long life" is only about 300 times; ternary lithium batteries theoretically up to 2000 times, the actual application to about 1000 times the capacity will decay to 60%; and lithium iron phosphate battery real life that 2000 times, at this time there is 95% of the capacity, the concept of cycle life more than 3000 times more.
A variety of factors, the use of lithium iron phosphate pack characteristics can be broadly expressed as follows: relatively large size, low temperature performance is not good, can maintain a relatively flat decay rate during the life of the general with about 8 years is possible; but if used in the south. Lithium iron phosphate battery life is a little longer than 8 years.
The difference between lithium iron phosphate and ternary lithium batteries.
① Energy density comparison
Lithium iron phosphate monomer, energy density of 120Wh/kg, lithium iron phosphate group 80Wh/kg; ternary lithium battery monomer, energy density of 180Wh/kg, group energy density of 110Wh/kg. from the data, in terms of energy density, ternary lithium battery is better than lithium iron phosphate.
②Safety comparison
Ternary lithium battery liquid electrolyte flammable and explosive, in the long-term use of the process is easy to trigger the "thermal runaway", the growth of lithium dendrites in the charging and discharging process is easy to puncture the diaphragm, causing the battery short circuit, causing safety risks. The lithium iron phosphate battery pack in actual use has the advantages of high temperature resistance, strong safety stability, and better cycle performance.
③ Cost
As lithium iron phosphate batteries do not contain precious metal materials, so the cost of raw materials can be compressed very low. Ternary lithium batteries are lithium nickel cobalt manganate as the cathode material, graphite as the negative material of lithium batteries, so the cost will be much more expensive than lithium iron phosphate batteries.
④Application areas
According to the data of the Trolley Data Intelligence Department, the battery of new energy buses is mainly lithium iron phosphate batteries, the use of lithium manganate battery buses also account for a relatively high, and ternary lithium battery because of its advantages to become the first choice for commercialization of passenger cars.
Through the above article on ternary lithium batteries and lithium iron phosphate real life which is longer article introduction, I hope it will help home. The current lithium battery market, mainly lithium iron phosphate and ternary lithium batteries. Lithium iron phosphate battery pack with its own numerous advantages to win the trust and recognition of the majority of users.
