The core problem of new energy vehicles-batteries!
It is very important to know the battery of electric vehicle, which will affect the mileage and speed of the vehicle. At present, the most commonly used battery is ternary lithium battery, so lithium mine has become very important, but after big data analysis and calculation, lithium mine on land is actually very limited. If new energy vehicles can be popularized all over the world, then lithium ore is absolutely not enough, so scientists have turned their attention to the ocean.
Joule, a scientific journal, published a latest scientific research paper, pointing out the feasible scheme and application prospect of extracting lithium from seawater. First of all, there are at least180 billion tons of lithium in the ocean. If all of them can be extracted, there will be no problem for human new energy batteries even if they are used for 1000 years, but we have to face a problem, that is, the ocean is too big, and it is one thing to extract lithium from seawater.
Cost is the biggest constraint!
At present, the main method to extract lithium from the ocean is to evaporate seawater. Obviously, this method is time-consuming and expensive. The concentration of lithium in seawater is only 0.17 mg l-1,which is obviously not practical, so developing a new extraction method is the solution. The Stanford team knew chemically that there was still a lot of sodium in seawater, and the chemical composition of lithium and sodium was high.
Researchers can greatly increase the extraction efficiency of lithium ions by using chemical batteries with titanium dioxide film. However, this method has not got rid of a problem, that is, it is still very expensive, and it is still far from extracting lithium from lithium ore, but it has made great progress and needs our scientists to continue to study hard.
New energy vehicles have broad application prospects!
With the popularity of Tesla in the world, electric vehicles are gradually accepted by people. Especially in developed countries, relevant plans have been made to completely eliminate fuel vehicles in the next few decades. At the same time, China, as the largest market in the world, is vigorously promoting the electric vehicle market, which will be a trillion-dollar market that no country or company will miss. Moreover, new energy vehicles represent the integration of Internet technology and traditional vehicles, intelligent driving, driverless driving, and a lot of Internet thinking.
Let new energy vehicles have a lot of imagination, and new energy vehicles have other advantages. For example, they don't make noise and accelerate very fast. At the same time, the biggest advantage is that they can protect the environment. You know, the greenhouse effect of the earth is very serious. If human beings can completely abandon fuel vehicles, the environment of the earth will be greatly improved, thus realizing the sustainable development of human beings and making our living environment more and more beautiful.
