electricity has played a very important role in people's production and life. Scientists also invented batteries to store electrical energy for easy carrying. However, the battery life problem has always plagued people, and many people often suffer from battery life anxiety.
Speaking of which, you may not believe it. As early as 180 years ago, scientists invented a battery with super battery life. It has been discharged for 180 years and it seems that there is no sign of slowing down. .
What is even more unacceptable to modern people is that the working principle of this battery has not been understood so far, it is simply a face.
In 1840, Oxford University purchased a batch of experimental equipment. Among these experimental equipment, a humble Newton electric bell (Oxford Electric Bell) was inadvertently rewriting history.
Newton electric bell experimental equipment, mainly to study "contact tension theory", mainly to verify statics theory and chemical effects.
Newton electric bells are actually very simple in structure. There are two brass bells. Below the bells are placed a dry battery . With the participation of batteries and conductors, a series dry battery circuit is completed.
In order to make the copper bell ring, pass a thin wire in the middle,There is a metal ball with a diameter of 4 mm at the end of the filament.
When the metal ball touches one of the copper bells, the copper bell will guide the circuit electrons into the metal ball, that is, the dry battery charges the metal ball, and then the metal ball is repelled by static electricity. At this time, the other electric bell will absorb the metal ball , And collided with the metal ball, and it was repeated in this way, forming a ringing ring with a period of 2 Hz oscillation.
is such an experiment. From the moment the power was turned on in 1840, it has not stopped until now. That is to say, the two batteries in series have been continuously discharged for more than 181 years. Because the time to make the electric bell is earlier.
Some people say that this battery is too powerful. If you disassemble it and study it, wouldn’t it be better to improve modern batteries.
However, as far as the current situation is concerned, these ideas are basically impossible to achieve. The dry battery is covered with sulfur, and its internal structure cannot be seen with the naked eye. Not only can it not be seen or touched, because the whole The electric bell was covered by a glass cover.
To study the battery, it is necessary to destroy the circuit of the current electric bell. It is estimated that no scientist would dare to do this.
Regarding the Newton electric bell, the scientific community has formed a consensus that as long as the electric bell keeps running, no one will destroy it and let it continue like this.
Compared with the continuous discharge of the dry battery of the Newton electric bell for 181 years, the performance of the battery is now a bit dwarfed. Let alone the continuous discharge for 181 years, even if it is not discharged, it will be useless in a few years, and even will corrupt.
However,Regarding the claim that modern batteries are not good, NDB of California, USA, expressed dissatisfaction, and they claimed to the outside world that they had manufactured a battery that could last for 28,000 years.
In August 2020, NDB announced to the public that they have verified through experiments that a nano diamond battery with an approximately infinite life span.
Nano-diamond batteries absorb the advantages of nuclear power plants and perfectly avoid the disadvantages of nuclear radiation.
In fact, the waste of the nuclear power plant : radioactive graphite must be protected by packaging to avoid environmental pollution and biological safety.
The nano-diamond battery is radioactive graphite from nuclear power plant waste. The radioactive graphite is rich in C-14 reflective isotope. After decay, it releases an antineutrino and a decay electron. The graphite is purified and made into tiny C- 14 diamonds.
and then inlay tiny C-14 diamonds inside the diamond. The radioactive C-14 diamond loses electrons, and the diamond lattice gets electrons, so the current is generated. This is the diamond battery Fundamental.
Some people even describe the diamond battery as a sandwich battery, because it looks like a sandwich. The C-14 diamond acts as the ham of the sandwich, and the diamond is equivalent to the sandwich bread.
Because the diamond battery uses the principle of nuclear decay,Theoretically speaking, nuclear battery has a longer lifespan. The half-life of C-14 is 5730 years, which means that after 5730, the battery power is still half, which can be said to have strong continuous power supply capability.
However, for people who talk about nuclear discoloration, even if the battery life is longer, they will not use it. After all, the effect of radiation on the human body is irreversible.
And Professor Scott from the University of Bristol of UK said that there is no need to worry about this radiation problem. You can avoid radiation by wearing a coat on the C-14 diamond. , Can allow C-14 to transmit high-energy particles inside the diamond. Once the high-energy particles want to penetrate the radiation to the outside, the diamond jacket can block its transmission.
In addition, Professor Scott also made an analogy to the value of radiation. Putting a diamond battery around, the radiation received by the body is equivalent to that of a banana. This radiation is basically Can be ignored.
NDB plans to launch a low-power version of commercial nano-diamond batteries within two years. The low-power version will be applied to low-power devices such as smart homes and pacemakers. The high-power version will be officially launched within five years.
written at the end
There is no doubt that the long-lasting battery life has become a pain point in people's lives.
Newton electric bell dry battery that can last for 181 years,Its legend is still being written, but the legend still belongs to the laboratory after all.
Modern people are also ready to try to write a new legend and bring long-life batteries into the homes of ordinary people.
