　　In life, you must be worried about whether your mobile phone has sufficient power and whether it needs to be charged immediately. Therefore, if you are given a battery that does not need to be charged for several months, you will be happy immediately. Would you be surprised by a battery that never needs to be recharged in your lifetime? If you were given a battery that never needed to be recharged for hundreds of generations, would you think it was a myth? Let me tell you, American scientists have created this myth right now .

　　So how are myths created?

　　It turns out that earlier, scientists discovered that when radioactive substances decay, they can release charged particles. If certain special methods are adopted, the charged particles can be tamed and gathered together to form an electric current. Later, scientists based on this discovery and discharge principle invented large-scale nuclear batteries for use in industry and aerospace. For example, in the aerospace field, nuclear batteries can be installed on exploration satellites with insufficient solar energy, or on unmanned spacecraft launched outside the solar system.

　　Unfortunately, nuclear batteries must be equipped with a solid semiconductor that collects charged particles, but due to the action of radiation, the solid semiconductor will soon be damaged, and in order to reduce the degree of damage, the nuclear battery must be made large enough. Just because it is difficult to make nuclear batteries smaller, it is difficult to use them in small or micro electronic devices, and naturally it is difficult to make them into mobile phone batteries.

　　Until recently, the situation has turned around. American scientists have come up with a clever plan to "slim down" nuclear batteries. They have replaced the easily damaged solid semiconductors in the nuclear batteries with less susceptible liquid semiconductors. This can not only complete the collection of charged particles. Mission, and it can also "slim down" significantly. It can be said to kill two birds with one stone. The circular nuclear battery developed based on new ideas has a diameter of 1.95 centimeters and a thickness of only 1.55 millimeters. It is only a little larger than a 1-cent coin, but its power is 1 million times that of ordinary chemical batteries.

　　Scientists believe that in the distant future, micronuclear batteries will be widely used in small and micro electronic systems, such as microelectronic instruments used to analyze blood samples. Because nuclear batteries provide power for a very long time, by then, only a coin-sized battery will be needed to keep our mobile phones from charging for 5,000 years. In addition, batteries for electric vehicles, which are becoming popular, are also expected to realize the dream of people not having to recharge for at least a lifetime.

　　As for whether nuclear batteries will cause nuclear pollution, scientists pointed out that this problem was solved at the same time when it was invented, and people do not need to worry about it.
