After the market scale of new energy vehicles continues to expand, more and more manufacturers have entered this track. At the same time, many new energy vehicle manufacturers have also begun to independently develop power batteries, after all, power batteries can be called the "heart" of new energy vehicles, and it is precisely for this reason that there have been many sayings about the choice of batteries.
At present, the mainstream batteries include ternary lithium batteries, lithium iron batteries, etc., which can be said to have their own advantages, so the number of supporters between them is not a few. Some people believe that ternary lithium batteries have excellent pit cooling ability, which can maintain a high energy density under the extreme situation of low temperature, and can effectively prevent the energy density and service life of the battery from being reduced due to low temperature environment.
Some people also believe that lithium iron batteries have a better service life and excellent safety, and can effectively reduce the number of times users replace batteries under the high cost of power battery replacement. At the same time, due to the characteristics of new energy vehicles themselves, the possibility of spontaneous combustion and explosion will be higher in the event of an impact or other conditions, so the safety of the battery is also very important.
In fact, from this comparison, it can be seen that these two batteries have their own advantages, and there is no way to use a simple evaluation to explain who is better to choose these two batteries, but should choose according to their own needs and preferences.
The biggest feature of ternary lithium battery is high energy density, which means that under the same volume and density of the battery, ternary lithium battery has a better mileage. Due to some characteristics of new energy vehicles, the volume of power batteries is actually impossible to expand all the time.
In addition to the battery life, the ternary lithium battery performs better in cold conditions, and has excellent performance, even in cold conditions or even in low temperature conditions for a long time, it still has a high battery life and good discharge efficiency. In fact, this also means that ternary lithium batteries are more suitable for consumers in some low-temperature areas.
Nowadays, the cruising range and cold resistance can be said to be one of the important standards of new energy vehicles, perhaps high cruising range can not become a high-end new energy vehicle, but high-end new energy vehicles basically need to have the advantage of high cruising range. It is precisely for this reason that most of today's high-end cars are using ternary lithium batteries.
The advantages of ternary lithium batteries are obvious, but the disadvantages are actually obvious, that is, the price of ternary lithium batteries is higher, and at the same time, they are slightly inferior in thermal stability. Today's power batteries may actually lead to spontaneous combustion in the face of high temperatures, especially in the case of impact, which is why the safety of ternary lithium batteries is not as good as that of lithium iron batteries.
If the advantage of ternary lithium battery is excellent performance, then the advantage of lithium iron battery is that it is more stable, which means that the service life of the battery will be longer and the number of cycles will be more. After all, the cost of the power battery accounts for about half of the cost of the new energy vehicle, and the service life of the new energy vehicle will be higher than the power battery, which means that it is difficult to avoid the situation with the battery.
Judging from the feedback of some users, the earliest iron lithium battery new energy vehicles have been used for about 9 years, but if they can be well maintained, they still have a range of 400 kilometers, and the battery attenuation is below 10%, and ternary lithium batteries are obviously unable to do this.
However, the service life of lithium iron batteries also needs good maintenance to maintain, basically half a month or a month needs to be fully charged for battery calibration, which is also troublesome after all.
Lithium iron batteries basically have more than 2,000 cycles, but ternary lithium batteries can only have about 1,000 cycles. In fact, there is a big gap.
From the perspective of market share, ternary lithium batteries still have a high market share, but the market share of lithium iron batteries has begun to rise gradually.
As for how to choose, in fact, it is still the point mentioned above, according to the needs of individual use, after all, everyone's car situation is not the same, and the degree of attention to different performance parameters is not the same. If it is really difficult to choose, you can also list your personal needs as standards and specific proportions, score the two batteries according to different specific proportions, and choose the battery that is more suitable for you.
