It's summer and cell phones are particularly prone to heat, which sometimes affects the stability of games. Under such circumstances, some netizens asked the author privately: Will long-term heating of the mobile phone affect the life of the mobile phone?
If you have a prolonged fever, it will first affect the battery life of your mobile phone. The operating temperature of mobile phone batteries is too high, which mainly affects the actual life of lithium batteries.
So, will this have a big impact on cell phone battery components, such as processors, cameras or memory? In fact, the so-called heat of a cell phone can reach up to 40 degrees and it cannot withstand even the highest temperatures.
In fact, the components of cell phonesThey can withstand much higher temperatures than anyone thinks. When installing the mobile phone motherboard, the temperature reaches 200 degrees. Even if it is used for a long time at high temperatures, it will not cause any slowdown or blocking.
What may be affected is the attenuation of read and write speeds caused by too many hard drive erases, as well as protection against CPU underclocking caused by high temperatures.
However, if your cell phone is used at high temperatures for a long time, you still need to be more careful. The battery has poor heat resistance. If the outside temperature is too high or the battery continues to operate at high frequency, the battery cannot withstand the pressure and may explode.
It is easy to heat up the phone.Dangerous scenarios include playing games while charging, high ambient light temperature, and other factors. When using your mobile phone on a daily basis, try to avoid these two usage scenarios.
In summary, long-term hot running of cell phones is generally not a big problem, at most it will reduce battery life and endurance. However, for safety reasons, it is best to try not to leave your cell phone for a long time in a high temperature environment.
Measures:
1. Do not use your cell phone while charging. This can not only slow down the temperature rise. of your cell phone, but also to effectively protect it from the battery of your cell phone. Of course, if you need to use your phone while it's charging,don't play big energy-consuming games, otherwise it will get even hotter!
2. Do not use a protective case when charging, avoid using a protective case with poor heat dissipation or remove it directly when the phone is hot.
3. Use your cell phone's heater when necessary, but most people don't need it. Almost everyone who uses it is a serious patient when it comes to “mobile games”. Large mobile games consume a lot of power, so using a cell phone radiator can cool the phone. Although the effect is not perfect, it still has a good heat dissipation effect.
4. Physical cooling. When it is hot and the ambient temperature is high, the heating and cooling of the mobile phone will be slower. At this time, the environment can be cooled to achieve the effect of cooledmobile phone installation. For example, if the fan blows, so does the cell phone.
Why do lithium batteries swell? Experience tells me that if the temperature is too high, the discharge current is too large or over discharged, they will swell in a few minutes, and you will still be able to hear the sound.
Why do lithium batteries catch fire? Fires can occur because the diaphragm is damaged or the temperature is too high.
There are two common lithium batteries, one is lithium iron phosphate battery and the other is ternary lithium battery.
The cathode materials of the two batteries are different. Lithium iron phosphate battery is safer. This battery will only burn at 800 degrees Celsius.
Ternary lithium batteries are not as safe as lithium iron phosphate batteries burn at 200 degrees Celsius.
Lithium batteries have a separator inside. This separator can let lithium ions pass, but it cannot let electrons pass. In this way, electrons can only pass through the external circuit, and only in this way can the external circuit generate current.
This separator is very important. If the separator is damaged, the positive and negative electrodes will be in direct contact, causing the battery to short circuit.
If the battery is short-circuited, it will explode or catch fire.
When using lithium batteries, be careful not to bend or puncture the battery, as this will damage the diaphragm.
When using lithium batteries, the current and voltage during charging should not exceed the specified values, otherwise the lithium battery may catch fire.
It is recommended to use original chargers to charge mobile phonesand purely electric vehicles.
Major automakers are also constantly looking for ways to improve the safety of ternary lithium batteries. If used correctly, ternary lithium batteries are still very safe.
Why Lithium Batteries Explode
Lithium batteries explode due to thermal runaway or diaphragm damage.
Thermal runaway is easy to understand. This means overheating. If the lithium battery overheats, it will burn, catch fire and explode.
Lithium batteries have a separator inside. If the separator is damaged, the positive and negative electrodes will be in direct contact, resulting in a short circuit.
If the battery is short-circuited, the battery will also explode instantly.
Therefore, when using lithium batteries, do not bend the battery orDon't pierce it. This is very dangerous behavior.
When charging, do not overcharge, and the voltage and current should not exceed the specified values.
If the voltage and current exceed the specified values, the temperature of the lithium battery will also be too high, which may easily cause the lithium battery to explode and catch fire.
Therefore, it is recommended to use the original charger when charging.
There are two types of lithium batteries commonly used in pure electric vehicles, one is lithium iron phosphate battery and the other is ternary lithium battery.
Ternary lithium batteries have high energy density and light weight, but their safety is not good.
Lithium iron phosphate batteries are very safe, but have low energy density.
Lithium iron phosphate batteries will not burns before 800 degrees Celsius, and ternary lithium batteries will start burning at 200 degrees Celsius.
Major automobile manufacturers are also constantly looking for methods to improve the safety of ternary lithium batteries.
If used normally, ternary lithium batteries are still very safe. (Images/Text/Photos: Questions and answers called the beast) @2019
You are truly ignorant and fearless.
The temperature is too high: the electrolyte decomposes and the cathode material decomposes. Among them, the cathode material composed of ternary lithium cobalt oxide decomposes, which will produce a large amount of oxygen and explode.
The discharge current is too large: the internal heat cannot be dissipated, which will cause heat accumulation and excessive temperature. The electrolyte decomposes slowly at 70-80 degrees. When a batterygeneral is discharged at 3°C, a temperature rise of 15-20 degrees is normal. The higher the rate, the greater the temperature increase. Batteries of different designs have very different temperature rises.
Overdischarge: The base copper foil of the negative electrode will migrate to the positive electrode at a low potential, causing copper to precipitate on the positive electrode. The crystal structure of the positive electrode is destroyed and a. A layer of copper is deposited on the surface of the electrode. Serious direct The positive and negative electrodes are connected, not to mention the SCI membrane. It will also make you angry.
As for the wires you said are flexible, each wire specification has a current carrying capacity. Under different currents, there is also an increase in temperature and you should do it next to the TV. the prochain times, maybe Baidu will get the video of the lithium battery explosion first.
