Lithium batteries are not subject to short circuits when charging, and above all they are not radioactive. Don't mislead people~
To put it simply, this is a problem with the electrochemical system and battery manufacturing. If the workmanship is not good, there may be something inside the battery. For example, metal shavings, powder particles, etc. can easily cause micro-short circuits.
The negative electrode of lithium batteries is generally made of carbon. When charging incorrectly (such as high current, excessive voltage, low temperature), some "dangerous" chemical reactions are likely to occur, resulting in certain chemical reactions. battery safety issues.
To summarize, lithium batteries are more likely to have safety issues when charging (than discharging). HASAfter all, it is an energy storage process. Good quality lithium batteries are less likely to have the so-called. "Short circuit while charging" problem, so everyone should choose qualified quality lithium batteries.
The voltage of the lithium battery is normal after a short circuit
In physics, a short circuit means that the positive and negative poles of the power supply are directly connected without pass through electrical cables. Appliances. The consequence is usually that excessive current will burn out the power supply.
If you want to short circuit a lithium battery, simply take a metal wire (like iron wire and copper wire) and let one end touch the front of the battery and the other end touch the back of the battery - Done This can be done not only for lithium batteries, but for all short batteries.
Also, ordinary batteries will not explode due to a short circuit, but you should not touch live parts during a short circuit. In my experience, when a 6V battery is shorted, it stings on contact with human skin. Reminder: Do not short circuit or touch the voltage when it is around 40V, because according to some books, voltage below 39V is a safe voltage, and above 39V, it may cause electric shock people.
Also, the short circuit you mentioned could mean that the battery in the computer case is shorted, right? Maybe you misunderstood. If you want to clear the memory of the motherboard chip, do not short circuit the battery. Instead, short circuit both poles of the circuit to discharge all the electricity inside.
The normal voltage of a lithium battery after a short circuit may be due to the reasonss:
1. Protection circuit: Many lithium batteries have built-in protection circuits that can protect. The battery in case of excessive current or short circuit. Turn off the battery output to avoid battery damage. When a short circuit occurs, the protection circuit quickly cuts off the current to maintain the normal voltage.
2. Internal Resistance: There is some internal resistance inside the lithium battery. When a short circuit occurs, current flows through the internal resistance to create a voltage drop, thus keeping the overall voltage normal.
