Which of the graphene battery and lead-acid battery is good to mention electric car batteries, everyone is familiar with these three batteries, lead-acid batteries, lithium ion batteries, and graphene batteries in recent years. So, do you think that when the new national standard is officially executed, which battery will the electric car choose? Let's take a look at each battery characteristics. The lead-acid battery is important from a tube-type positive electrode plate, an anode plate, an electrolyte, a partition, a battery tank, a battery cover, a pole column, a liquid cover, and the like.

Its electrode is composed of a oxide of lead and lead, and the electrolyte is an aqueous solution of sulfuric acid. The important advantage is that the voltage is stable, the price is cheap, the disadvantage is lower than the energy, the service life is relatively short, and often maintenance. It is undeniable that the lead-acid battery is dominated in the current market.

In general, the lithium-ion battery is important to include four components of the positive, negative electrode, diaphragm, and electrolyte. Positive electrode material is generally some lithium layered compounds, currently common commercial positive electrode materials are important to lithium cobaltate (LiCoO2), lithium manganate (liFePO4), and ternary materials (LIMNXCO1-X- Yniyo2), etc. Compared with the lead-acid battery, the lithium-ion battery is relatively light, easy to carry, more energy density, and there are many longer life, but the price is more expensive and poor stability.

The so-called graphene battery can be understood as a new energy battery developed by a black metal battery that we usually say, which uses lithium ions to quickly and large through the characteristics of moving a large number of moving motions, and developed a new energy battery. As a new type of nanomaterial that is the most stronger, most hard, conductive conductive performance. At the same time, the weight of the graphene polymerization material is only 50% of the traditional battery, and the cost will be 77% lower than the lithium ion battery.

From the performance, the full graphene lithium ion battery is charged once, and it will not exceed 10 minutes. (The general industry is directly collectively collectively referred to as a graphene battery, not full graphene, which is the best, but why didn't the ovethylene battery? Become the lead? The application of graphene on the battery is important and silicon is bonded to the battery negative instead of the original graphite, which can improve the overall capacity and charging speed of the battery, but the performance improvement effect is limited. On the other hand, although many companies have launched a blackboard, most of them are in this area, and their prices are relatively high, so this is one of the reasons why they do not have significant applications.

In addition, graphene contamination is more severe, and the olene processing is used to use a large amount of sulfuric acid, and it is very troublesome. Simply, first, price; second, technology; third, handling trouble. We look at the introduction of the new national standard, which has a clear provision for electric bicycle speed, weight, etc.

, which means that large lead-acid batteries will gradually lose the market, and small lead-acid batteries will usher in a short period of time. However, with the advancement of environmental rectification, the lead-acid battery will also transition to a lithium-ion battery, and the lithium current will usher in a wave of explosive period. Another person will say, the graphene battery? Although the graphene battery has a lot of lead-acid batteries and lithium-ion batteries, it wants to be dominated, and its technology must be achieved.

Therefore, I personally prefer the application of small lead-acid batteries and lithium-ion batteries in future new national standard electric vehicles. Compared with the lead-acid battery, the average voltage of the lithium ion battery is higher, its energy density is high, in other words, the same size battery, the lithium ion battery capacity is more. In addition, the lithium-ion battery is relatively light, easy to carry, and a lot of life is relatively long.

In addition, the high and low temperature adaptability of the lithium-ion battery is stronger, and the factors affecting temperature are smaller, and green and environmentally friendly. Of course, there are three disadvantages of the lithium-ion battery. The safety stability is relatively poor, and if the operation is improper, it is easy to explode the risk of explosion.

In addition, the lithium-ion battery cannot be high current discharge and the processing requirements are high, and the cost is higher. Compared with the lithium-ion battery, the price of lead-acid batteries is relatively inexpensive, and the public is easier to accept. In addition, the high magnification discharge performance of the lead-acid battery is better.

The most important thing is that lead-acid battery recovery is higher than lithium ion batteries. However, lead-acid batteries also have their own disadvantages, such as heavy metals to cause environmental pollution; lead-acid battery energy density is lower than the lithium-ion battery; and its life is not as good as lithium-ion battery. Although the lithium tram has a lot of advantages, in fact, lead-acid electric vehicles are mainly, its important factors are the imperfect technology, although some lead-acid giants and electric car giants began to develop lithium eugenics, but as a In the field of newly involved, many companies are currently in full exploration and exploration, and the initial product often cannot reach maturity.
