When environmental protection slogans are loudly shouted, it is necessary for us to always check whether our actions are in harmony with the slogans, and whether they are mixed with the noise of some commercial private goods?

When all kinds of spells against the vicious environment are on the scene, the electric car in a dazzling coat steals the spotlight from time to time, and even has a taste of playing the role of a savior. Electric cars don’t drink gasoline and diesel, don’t have that hateful exhaust pipe behind their buttocks, and the noise they make when driving is as light as a whisper, instead of traditional cars that are always coughing like an old man... It seems that there is no difference The reason for accepting electric vehicles is so convincing that experts say that electric vehicles are "green and environmentally friendly vehicles with a promising future". Therefore, we also understand that "in the policy of restricting license plates, pure electric vehicles are not How correct is the practice of "listing the purchase restrictions". It can be expected that a city full of charging piles is coming.

Behind the extremely glamorous surface, is there any hidden worry? Undoubtedly, before the perpetual motion machine was invented, any driving device must consume energy, and in essence, all things that need to consume the earth's resources are a wolf with a big tail for the human environment. The electrical energy of an electric vehicle is stored in the battery, which is charged with electrical energy and supplied to the drive motor. It is not an exaggeration to regard it as the stomach, liver and kidney of the entire vehicle. What's terrible is that this thing is very short-lived, and its lifespan is far inferior to the lifespan of human organs, especially the lead-acid batteries that are widely used at present. The energy storage is attenuated, and the cycle life has been lost, so the old one can only be discarded and a new one will be equipped.

That's right, the exhaust gas of traditional cars is discharged to the sky, which has made us suffer enough from the smog, but this time, the discarded batteries of electric cars can't go to the sky, they can only go to the ground, but they can't be like a pile of ordinary The domestic waste will slowly degrade and cannot be eliminated in 10,000 years. So where should they all go?

Soldiers come to block, water comes to cover, this is one of the good strategies in the minds of the Chinese. The sky is full of smog, and some people have figured out a way to live in a plastic cover. They can also wear masks and gas masks when going to work and shopping. So, how can we be sure of winning the battle against the astronomical accumulation of discarded car batteries?

A friend who has studied electric vehicle batteries for many years told me that in fact, the disadvantages of vehicle batteries are not only the pollution of a large number of scrapped batteries, but also the terrible hazards in the battery manufacturing process: lithium metal electrolytes in manufacturing materials, strong Flux, cobalt metal and the like are all carcinogens; the impact of the lithium-iron film material necessary for the manufacture of batteries on organisms cannot be ignored; the large amount of carbon dioxide emissions generated during the production of batteries is also terrible. Even for sodium-sulfur batteries, nickel-cadmium batteries, lithium batteries, fuel cells, etc. that are being developed, pollution during their manufacture and use is still inevitable. In addition, can you ignore the power consumption during battery charging and power supply? Can it avoid the huge pollution in the refining and production process of battery manufacturing materials? Can you be numb to the damage to the environment caused by coal and gas consumption when increasing power generation?
