In the current short-distance transportation market, electric vehicles have become the first choice for mass travel. For many people, electric vehicles are a "consumable". Lead-acid batteries need to be replaced after two or three years, and many people say that the cost of using electric vehicles is getting higher and higher.
Especially in winter, the battery life is greatly attenuated, and some users who usually do not pay attention to maintenance will basically have to replace the battery in a year. Today, I will share with you the durability ranking of the battery, the battery life is as long as 10 years, and the cold weather is not afraid of traveling, which can be described as the "strong enemy" of lead-acid batteries, let's see how you choose!
Fourth place: lead-acid battery
In terms of battery durability, lead-acid batteries are ranked last. But even so, it can still occupy the mainstream of the market, relying on mature technology, stable performance and low cost. The number of cycles of ordinary lead-acid batteries is about 300-500 times. The more often it is charged, the faster it needs to be replaced, and some car owners basically need to replace a new set of batteries in about 2 years.
Third place: graphene battery
When the concept of graphene was first introduced two years ago, many car owners did not think so. However, judging from the actual riding data, graphene batteries are indeed more durable than ordinary lead-acid batteries. To put it simply, the graphene battery is the "upgraded version" of the lead-acid battery, which can reach 600-800 times from the perspective of the number of cycle charging and discharging, and it is no problem to use it for about three years normally.
Of course, the extension of service life means that the cost increases, which is 300-500 yuan more expensive than lead-acid batteries. From the point of view of cost performance, many people would rather choose lead-acid batteries.
Second place: lithium battery
At present, many brands of high-end models have begun to carry lithium batteries. From the advantage point of view, the ternary lithium battery is small in size, high in energy density, and has better charging and discharging performance, and the number of cycle charging and discharging should reach about 1500 times. Even if the performance is degraded in the later stage, this time can be as long as 5 years. Even in cold weather, performance is not affected too much.
Although lithium batteries have many advantages, they also have great disadvantages, that is, weak safety performance. There have been many cases of fire and explosion of electric vehicles before, all of which are caused by lithium batteries, although it is caused by incorrect charging methods, but many car owners dare not use lithium batteries because of this.
1st place: sodium battery
Sodium batteries may be a new concept for many people, but with the update and iteration of technology in the electric vehicle industry, the performance of batteries in all aspects must also keep up with the demand. At present, Xinri and Tailing sodium battery electric vehicles have been sold, and the battery performance is still excellent in ultra-low temperature environments.
It is reported that the cycle life of sodium batteries can reach 2000-3000 times, and the power can be charged to 80% in 10 minutes, and the service life is as long as 10 years. And sodium, as one of the rich metal elements, is lower than lithium, and some people familiar with the matter revealed that the cost of sodium batteries may only be half of lithium batteries.
In this regard, many people said that they hope that sodium battery electric vehicles will be mass-produced as soon as possible, and then as more brands pour into this market, perhaps sodium batteries will become the new market mainstream.
