The battery car is also polluted
First, the battery is polluted. The electrolyte for lithium batteries is organic, which decomposes lithium hydroxide after volatilization. In severe cases, it can damage people's vision. Lithium batteries also contain a certain amount of cobalt. An electrolyte containing a large amount of lead ions in a waste lead storage battery will pollute the soil if it is discharged at will.
According to the survey, the average service life of each electric vehicle battery is 18 months, that is, one year and a half will eliminate a group of electric vehicle batteries, which are hard-to-decompose and heavily polluted waste products. In China, the industrial chain of lead-acid batteries has been relatively complete, but the lead recovery rate is not high, coupled with the lack of supervision, the recycling of lead-acid batteries is also a big problem.
Second, energy consumption. Electric vehicles, as the name implies, replace the fossil energy of traditional motorcycles or automobiles with electricity. It seems to have indeed reduced oil consumption and reduced carbon dioxide emissions, but everyone has overlooked a problem, that is, the proportion of existing wind, water and coal power in China. China's electricity is still dominated by coal power. Coal mining can also cause pollution.
At the same time, our utilization of energy is less than 100%.
In order to promote sales, some battery car merchants have added a lot of special effects to the battery car. What is 100% environmentally friendly Barabara? It is said that there is no ground in the sky, just like when humans change battery cars to solve all energy and environmental problems. Your physics teacher has been crying on the podium! Keke~
At the beginning of 2016, a Japanese expert explained from the perspective of CO2 emission reduction through a 50-page PPT. According to the current power generation method, it is almost meaningless to develop an electric vehicle. Of course, it's just the current one.
China is vigorously developing new energy power generation. Why do you know it? It is for the future that battery cars and new energy vehicles are more environmentally friendly than traditional energy vehicles.
The battery car is indeed an improvement
History teachers have always stressed that history and society are progressive. The basic direction and trend of social and historical development is advancing or rising, but its development is not smooth sailing, but a spiraling or wave-like process. The root cause of this twist and repeatability is that the old social forces and the reactionary classes are reluctant to withdraw from the stage of history. In one sentence: we can't degenerate from a person with a linguistic mind to an ancient one, nor do we evolve from a monkey to a human now.
So some things that appear in our lives have their inevitability. Why are there battery cars, expensive cars, expensive maintenance, expensive gasoline, many people who have just entered the society can not afford to buy a car or can not afford to use a car, at the same time, the traffic situation is, blocking and blocking! And the bicycle is slower, farther Local, manpower can't keep up. It is precisely because the masses have this demand that the battery car between the car and the bicycle is born!
We will not stop discovering and manufacturing because of the destruction of pollution, and we will certainly reduce damage and solve pollution problems in this process.
Pure electric vehicles are a progressive tool! Not only represent progress, but also reduce pollution emissions. It does not require the use of fossil energy itself to reduce the environmental demands and damage; and it is zero-emission, quiet and reduces pollution.
If we divide manufacturing and consumption into four major links, first, power supply; second, manufacturing; third, product application; fourth, recycling.
In the four major links, the manufacture and consumption of pure electric vehicles can be improved. In the power supply, manufacturing and recycling, efficiency can be improved, but emissions can not be avoided. Only product application can avoid emissions.
Here, can we think that for the energy-saving and environmental protection of the manufacturing industry, the product application link is the only place where the economic benefits and social benefits can be achieved at the same time. This reminds us that when manufacturing power tools, we should consider using non-fossil energy to provide kinetic energy.
In summary, pollution emissions are ubiquitous and full of industrial production and social life. Pure electric vehicles show obvious environmental advantages. In the application of the product, it has zero emissions, no tail gas pollution, and even no waste pollutants such as coolant and oil.
In order to reduce the pollution of battery vehicles, this requires the joint efforts of our entire society, the development of new energy sources, the reduction of emissions in the production chain, and the final recycling of discarded batteries. Energy saving and environmental protection is not just a slogan, it is closely related to our future. We are not only beneficiaries, but also participate in them and become helpers.
