If we limit ourselves to the idea of chemical batteries, humanity will only be able to cross the limit of energy density the day it perishes.
Why! To use an analogy, a house of a certain volume can only be carried by one person in the house with a bucket of water (assuming a bucket of water takes up no space). How can we retain more water? The answer is to use children to carry the water, because children are small, and if more children can be accommodated in the same room, more buckets can be packed.
Why use lithium as a battery? Everyone memorizes the periodic table of elements and chemical batteries. Lithium has the most atoms per kilogram (equivalent to a house). Each lithium atom (each child) provides a useful electron. The potential of the lithium electrode is high, so lithium is used as the electron. battery. . Everyone has pfully understood these basic theories. When Edison invented the lead-acid battery, he thought of lithium. However, due to the technical limitations at the time, the lithium was too active and could not react stably, and the amount of lithium could not be. prepared was also small, so he had to choose lead as the main chemical battery material.
But chemical batteries must also contain electrolytes. Although electrolytes are auxiliary functions, they are essential substances. Only with the joint participation of metal electrodes and electrolytes can the process of electron transfer and utilization be completed. Counting them, the energy density of chemical batteries has decreased significantly. Theoretically, the highest energy density is that of lithium-air. Because it theoretically reacts with oxygen in the air to complete the processprocess of transfer and use of electrons. Is he not using electrolytes? impossible. In addition, lithium reacts with carbon dioxide and nitrogen in the air, so oxygen cylinders can only be used after all, the so-called lithium battery energy density laboratory -air can only achieve one kilowatt hour per kilogram. By the way, there are also commercially available aluminum-air and magnesium-air batteries. The energy density of existing aluminum-air batteries is 1 kilowatt hour per kilogram. Why not use it in cars? Some say that aluminum batteries are disposable batteries and cannot be recharged. It is not easy. Wouldn't it be nice to build an electrolytic aluminum plant in every city if it's close? The key problem that no one has mentioned is that batteries are not like people think. They canThey can discharge as much electricity as they want in an instant. Another key indicator of batteries, power density, is not high for aluminum and magnesium. If aluminum batteries are to be used to release the power that makes an electric car go fast, approximately 4 tons of aluminum batteries must be installed on the car. Who wants such a car? Some time ago, a foreign news revealed that aluminum air has the power to make a car last 2,000 kilometers. After translation, it became clear that the car could last 2,000 kilometers. This car can travel 2,000 kilometers at a speed of around 20 kilometers per hour. You don’t want such a car for free. It's cool to have 10 million, but the bank only allows you to withdraw 100,000 per day, so it's just haha! By the way, ordinary atomic children can only carrya bucket of water, while aluminum kids can carry three. This is also the fundamental reason why the theoretical energy density of aluminum air is second only to that of lithium air.
There is also the silicon electrode of the lithium battery. When silicon and lithium react, the volume increases three times and the electrode is broken. Can this person pierce the atom and restore it by hand? The touted solid-state lithium battery has high energy density and can be charged quickly. Fast charging of liquids has not yet been solved, but fast charging of solids can be achieved. In chemical batteries, chemical reactions must occur. How quickly can chemical reactions be implemented in batteries? Give.
No matter how much coal, oil and flammable ice there is, before the sun goes downe, the greenhouse effect created by the chemical fuels used by humans will kill itself first.
Why can't battery technology make a big breakthrough?
You can add onion and ginger to cook, and add a few drops of sesame oil when you eat. The specific. The method is as follows: Ingredients: 1 egg, 1 handful of seaweed Accessories: a little sesame oil, appropriate amount of salt, a little green onion, a little ginger Step 1: Cut the green onion and ginger and set aside. Step 2: Set aside the seaweed. Step 3: Beat the eggs and set aside. Step 4: Add water to the pot. Step 5: Add the onion and ginger. Step 6: Wait for the water to boil. Step 7: Add the seaweed. Step 8: Add the egg liquid. Step 9: Add salt. Step 10: Take it out of the pot and put it in a bowl, add a few drops of sesame oil and serve.
When will new energy vehicle battery technology break through?
If we limit ourselves to the idea of chemical batteries, humanity will not be able to break through the limit of energy density until the day it perishes.
