Pacific Automotive Network's ternary lithium battery has a longer cycle cycle. The ternary material has advantages in charging rate, discharge rate and discharge performance at different temperatures, while the lithium iron phosphate material has better cycle performance, 1C cycle. More than 80% of the initial capacity can still be maintained after 5000 times.
Lithium iron phosphate batteries for electric vehicles are the best. Ternary lithium batteries have the possibility of spontaneous combustion and explosion.
The number of charge and discharge cycles of lead-acid batteries is about 350, the number of charge and discharge cycles of ternary lithium batteries is about 800, and the number of cycles charging and discharging of lithium iron phosphate batteries is about 2000. The storage temperature of lithium iron phosphate battery is -10 to 35°C and the discharge working temperature of lithium iron phosphate battery is -20 to 65°C.
Before buying a lithium battery, first check whether the battery cells it uses are grade A. Second, look for a lithium battery. lithium battery produced by a major manufacturer, mature production technology, guaranteed after-sales service, and the market reference price of lithium batteries is 1,250 yuan/KW.H.
Lithium iron phosphate battery: Lithium iron phosphate battery refers to a lithium-ion battery using lithium iron phosphate as the positive electrode material. The particularity of this type of battery is that it does not contain precious metal elements (such as cobalt, etc.). Since they do not contain precious metals, the raw material cost of lithium iron phosphate batteries can be reduced very little. In actual use, batterieslithium iron phosphate have the advantages of high temperature resistance, high safety and stability, low price and better cycle performance.

Will the number of charging times affect the life of the battery?
If you use an electric car every day, do you know the approximate lifespan of an electric vehicle's lithium battery? Is it true that lithium-ion batteries can only be charged and discharged 500 times? I believe most consumers have heard that the lifespan of a lithium battery is "500 times" and 500 times charging and discharging. After this number of times, the battery will “end its life” in order to extend its lifespan. battery, every time. Charging the battery only when it is completely exhausted will prolongDoes it actually last longer? the answer is negative. The lifespan of a lithium battery is "500 times", which does not refer to the number of charges, but to one cycle of charging and discharging. A charge cycle means that all of the battery's energy is used from full to empty, then charged from empty to full. This is not the same as a single charge. For example, a lithium battery only uses half its power the first day and then charges slowly. If it is still the same the next day, i.e. if you charge it half and charge it twice in total, this can only be counted as one charging cycle and not two. Therefore, multiple charges may often be required to complete a cycle. Each time a charge cycle is completed, the battery capacity decreases a little. However, this reduction in power is very small. High quality batteries keepnt 80% of their original capacity after being charged several times. Many lithium-ion powered products are still in use after two or three years. Of course, lithium batteries still need to be replaced once their lifespan is reached. The so-called 500 times refers to the manufacturer's actual discharge at a constant discharge depth. It has been found that it can be recharged about 625 times, reaching 500 charge cycles. Due to various influences in real life, including the depth of discharge during charging is not constant, "500 charging cycles" can only be used as a reference for battery life.Influential, because the lifespan of lithium batteries is generally 300 to 500 charge cycles.
One of the advantages of lithium batteries is that they can be charged at any time and at a convenient time. You do not need to use the energy beforee recharge it.
A charge cycle means that all the energy in the battery is used from full to empty, then charged from empty to full. It's not the same thing as. charging once.
To put it simply, a 600 mAh lithium battery was charged from 0 mAh to 400 mAh for the first time. It used N milliamps, then recharged it to 150 mAh. finally charge 100 milliamps. When the last charge reaches 50 milliamps, one charge cycle of this battery has arrived
(400+150+50=600) The lifespan of a lithium battery is generally 300-500 cycles dump.
Assuming that the power provided by a complete discharge is 1Q, if the power reduction after each charge cycle is not taken into account, the lithium battery can provide a total of or the complete with 300Q-500Q of electricity
From this we know that if you charge 1/2 each time, you can charge it 600-1000 times; if you chacharge 1/3 each time, you can charge 900-1500 times
And so on. If you charge randomly, the number of times is variable
In short, no matter how you charge, the total amount of electricity added is 300Q to 500Q, which is constant< /p>
So it can also be understood this way: the lifespan of a lithium battery is related to the total charge capacity of the battery and has nothing to do with the number of charges .
The impact of deep discharge and deep charge and surface discharge and surface charge on the life of lithium batteries is not great.< /p>
When using a cell phone, you sometimes wait until the battery runs out before recharging it. In fact, this is a mistake. Current cell phone batteries are not suitable for excessive discharge. Excessive discharge poses serious risks to batteriess lithium, it may cause permanent battery loss, and in the most severe case, this may not be the case. can be turned on normally, so when you use it, you should charge it immediately when you see the battery alarm.
When you charge your cell phone, try not to charge it if you use a cellphone. and play while charging, it is easy to wear out the battery and shorten its lifespan. In addition, during the charging process, radiation will be generated, which is not good for your health.
