What is a nuclear battery that never shuts down| Love to play computer games - 上海419贵族宝贝-上海后花园1314-上海品茶网-阿拉爱上海

Mobile phones are developing at the speed of super Moore's law, from single core to today's 8 cores The screen has grown to 1080p, and the memory has grown from dozens of MB to 2GB now Everything in the mobile phone is being upgraded, but the cell phone battery is still standing still, and the fuel cell that has been said before has been delayed in coming into the market due to various technical problems. In order to solve the problem of battery life, many manufacturers can only increase the thickness of mobile phones so as to have more space for batteries. Recently, heat transfer nuclear batteries are available on the Internet, and it is said that they have been powered continuously for 20 years. The name of nuclear battery sounds awesome. What is it? Can it become the ultimate weapon to solve the problem of mobile phone's endurance?

Some people may wonder how such a mysterious thing as nuclear power can be made as big as a battery? However, there is such a thing in fact, and it is bought on Taobao. It is rumored on the Internet that this battery is called NanoTritium, which is a nuclear battery made of tritium and is only a few centimeters in size. However, this battery is not cheap. The price on Taobao is 6980 yuan, and it is second-hand.

However, this kind of nuclear battery is different from what we usually call nuclear battery and the nuclear battery carried on the Mars rover Curiosity. At present, all nuclear power stations use fission reaction of heavy elements to release heat, and then convert heat into electrical energy. The NanoTritium battery on the Internet is a radioisotope battery, which is different from the principle of nuclear power plants. This type of battery can be roughly divided into two types, namely, thermal conversion nuclear battery and non thermal conversion battery. The battery mentioned on Taobao is a non thermal conversion battery. This kind of battery uses beta particles released during isotope decay, that is, it uses electrons to generate electricity directly without using heat to generate electricity. NanoTritium nuclear battery uses the hydrogen isotope tritium, and its nucleus is composed of one proton and two neutrons. This is an element that will undergo beta decay, emit high-speed electrons (i.e. beta rays), and transform into helium 3 at the same time. These high-speed electrons shoot into semiconductors and generate current.

Because the half-life of tritium is up to 12.43 years, this kind of battery can provide batteries continuously for a long time. However, the current it generates is not large. If you really want the nuclear battery to power the mobile phone, the volume of the battery will be larger than the mobile phone itself. So at present, nuclear batteries are only suitable for those occasions that consume less power but need to be powered uninterruptedly for a long time, such as the power supply of built-in medical equipment, and military or space purposes.

In addition, we will worry about whether the nuclear battery will cause harm to human body. In fact, the nuclear battery is quite safe, because the decay of tritium will only produce high-speed electrons, which are unable to penetrate the human body. The use of low Z materials such as aluminum can be well shielded, so it is quite safe for human body, Unless you take a large amount of tritium orally or inject it into your body.

However, with the development of technology, maybe in the near future, we really only need a coin sized battery, and your mobile phone can be used for 5000 years without recharging.
