Let me ask, what are the most cutting-edge energy storage technologies currently? [Copy link]

 

As the title says. I heard that energy storage power supply is very popular now. I want to ask what are the most cutting-edge energy storage technologies? ?

New and good, only nuclear energy is recognized

The energy storage of power sources is divided into chemical energy storage and capacitive energy storage. The former is a battery and the latter is a large-capacity capacitor. The combination of the two technologies is a "supercapacitor", which is relatively new, but batteries are also developing and both have cutting-edge fields.

Nuclear energy itself cannot store energy, which has nothing to do with the original poster's question...

Energy is stored in the nucleus.

Wuzu Simeng published on 2022-6-21 20: 24Energy is stored in the nucleus.

You store energy in the nucleus, show it to everyone. It doesn't have to be too much, just one gram or even one milligram will do.

If you don't have the experimental conditions, you don't have to make actual substances, you can just write out the nuclear reaction equation.

　　Nuclear energy is a type of energy stored inside (nuclei)
　　Nuclear energy: energy released when the nucleus changes.
　　Nuclear energy can be obtained in two main forms: one is the fission energy released by the fission reaction of fissionable materials (nuclear fuel) in nuclear reactors; the other is the fusion energy released when two smaller nuclei combine to form a new nucleus with a larger mass at high temperatures (more than several million degrees).

I wonder if you want to see the formula for nuclear fusion or the formula for nuclear fission?

So how do you store energy in the nucleus?

"Do you want to see the formula for nuclear fusion or the formula for nuclear fission?"

I want to see the nuclear reaction formula in which you store energy in some kind of atomic nucleus.

"Do you want to see the formula for nuclear fusion or the formula for nuclear fission?"

Before the energy is stored in the nucleus and after the energy is stored in the nucleus, they must be two different nuclei.

The requirements can be lowered a bit: just write down the two different nuclides.

What maychang asked is essentially what I asked above.

It depends on the application of energy storage. Batteries and capacitors are the most common small-scale energy storage, and there are too many types. Larger ones include physical potential energy storage and chemical battery energy storage. There are also many types of physical energy storage, and chemical energy storage seems to be lithium batteries and liquid batteries at present.

Large energy storage is photovoltaic array + inverter array and grid-connected technology.

Small energy storage is battery + bidirectional inverter fast charging.

In fact, the core of large energy storage is DC→AC, and the core of small energy storage is DC←→AC.

"Large energy storage is a photovoltaic array + inverter array, grid-connected technology."

Photovoltaic arrays, inverters, grid connection... have nothing to do with "energy storage". These convert light energy into electrical energy, but do not store energy.

As far as I know, hydrogen has three kinds of atoms: 1H, 2H, and 3H, which are three kinds of nuclides. Their nuclei have 0, 1, and 2 neutrons respectively. These three nuclides are called isotopes. For example, a carbon atom with 6 protons and 6 neutrons in its nucleus has a mass number of 12, which is called carbon-12 nuclides, or 12C nuclides. A carbon atom with 6 protons and 7 neutrons in its nucleus has a mass number of 13, which is called 13C nuclides. Oxygen has three kinds of nuclides: 16O, 17O, and 18O.

Plutonium-239 could be artificially synthesized many years ago. When plutonium is irradiated with slow thermal neutron radiation in a reactor, neutron capture occurs accidentally, increasing the amount of plutonium-242 and plutonium-240.

The reaction you want to see:

Pu-238 and Pu-239 are the most common artificial isotopes. Pu-239 is produced by beta decay (β) using uranium (U) and neutrons (n) with neptunium (Np-239) as an intermediate.

A neutron from the fission of uranium-235 is captured by a uranium-238 nucleus to form uranium-239; a β decay converts a neutron into a proton to form neptunium-239 (with a half-life of 2.36 days), and another β decay forms plutonium-239.

吾妻思萌

chunyang posted on 2022-6-22 18:26 So how do you store energy in the nucleus?

A lot. For example:

A deuteron strikes uranium-238 to produce two neutrons and neptunium-238; neptunium-238 then emits a negative beta particle and spontaneously decays to form plutonium-238

Plutonium-239 is obtained by beta decay (β) of uranium (U) and neutrons (n), with neptunium (Np-239) as an intermediate.

Uranium 238 is irradiated with neutrons and undergoes some nuclear reactions to produce plutonium 239. This can be found in any undergraduate textbook on atomic physics. However, until now, no physicist has considered this as a means of storing energy. Nuclear energy already exists in uranium 238, but uranium 238 cannot sustain a chain reaction to release energy.
