Are lithium batteries afraid of low temperatures?

Are lithium batteries afraid of low temperatures? The weather is very cold. Many people find that the battery of the mobile phone is consumed very quickly when using the mobile phone outside, and sometimes crashes and touch screen failures occur. Professionals remind that low temperature has a great impact on mobile phone batteries. When using mobile phones in cold weather, some methods can be used to improve battery durability. Current mobile phone batteries are generally lithium batteries, and the chemical reaction rate of the battery is affected by temperature. A mobile phone in a low temperature environment for a long period of time will make the battery chemical reaction slow, resulting in low battery discharge current, reducing battery capacity, possible situations, rapid power use, black screen, dead, touch screen failure, unable to access the Internet, etc. . When entering a warm outdoor from a cold outdoor, temperature changes may also cause condensation inside the phone to form water mist, short circuit boards, or other problems. When you go out in cold weather, try to keep your phone fully charged and reduce power-consuming applications such as playing games, watching movies, and listening to music. It is best to put your mobile phone in a warm place such as your pocket or backpack. You can use earphones when making and answering calls. Try to prevent the mobile phone from being directly exposed to the cold air. Do not use the phone for a long time in low temperature. After entering the room from the outside, leave the phone for a while and wait for the water mist to evaporate before using it. If the mobile phone fails temporarily when used in a low temperature environment, you can turn it off and suspend use, and then let the mobile phone be used in a slightly higher temperature environment for a while, and the situation will be improved. The working principle of a lithium battery is to change the electrolyte inside the battery to show a potential difference between the positive electrode and the negative electrode, and then a current appears. The electrolyte moves slowly at low temperatures, which affects the transport activity of lithium ions between the positive electrode and the negative electrode, resulting in a decline in the charge and discharge function of the battery. Simply put, at low temperatures, it is not that the lithium battery is dead, but that the battery is not properly discharged. According to analysis, a general lithium battery will lose 20% of its capacity at 0 degrees Celsius, and may only lose half of its capacity at minus 10 degrees Celsius. The normal operating range of most mobile phone batteries is between 0 and 35 degrees Celsius. Anything lower or higher than this temperature is abnormal. Low temperature is not good for lithium batteries. If low power consumption is added, the damage will be even greater. Therefore, in order to protect lithium batteries, Apple has added a self-protection mechanism to automatically shut down when encountering low temperature + low power consumption and cannot be used. To this end, let's take a look at Apple's official instructions: the ideal operating environment for the iPhone is between 0c and 35c. When the room temperature drops to a certain temperature (about -10°C), Apple will automatically shut down.
