Lithium batteries are resistant to cold from minus 20°C to 60°C.
The cold resistance performance of lithium batteries mainly depends on the properties of their electrolyte and the materials of the positive and negative electrodes. Generally speaking, the operating temperature range of lithium batteries is from minus 20°C to 60°C. In this range, performance and battery life will not be greatly affected. However, when the temperature drops below minus 20°C, the battery performance drops significantly and may even cause battery damage.
In a low temperature environment, the electrolyte of lithium batteries will become viscous, which will slow down the migration speed of lithium ions, thereby affecting the discharge capacity of the battery. Additionally, low temperature will accelerate the speed of chemical reactions inside the base.tterity, causing an increase in battery self-discharge. Therefore, the lifespan of lithium batteries can be significantly reduced when used in cold environments.
In order to improve the performance of lithium batteries in low temperature environments, researchers have developed various new electrolytes and positive and negative electrode materials. For example, lithium batteries that use solid electrolytes can operate at much lower temperatures. Additionally, some research is exploring the use of new battery technologies such as lithium-sulfur batteries or lithium-air batteries to improve their performance in low-temperature environments.
Key points for purchasing lithium batteries:
1. Is capacity clearly marked?
No capacity clearly marked (such as1000 mAh or 1000 mAh) most likely use lower quality batteries or recycled batteries. Many inexpensive batteries on the market are made from recycled cells. Although they are cheap, they have a short lifespan and unstable quality can damage the phone.
2. Is there a standby time guarantee?
Standby time is the duration of continuous use from the time the battery is installed in the phone until the next charge. Generally, batteries sold in the market cannot guarantee standby time to customers. Indeed, the quality of the batteries is unstable. Many cheap batteries use poor quality cells, so the standby time is very short.
3. Whether to install a safety protection circuit board
Without a protection circuit board, the lithium battery may deform, leak and explode.Faced with fierce competition for lower prices, each company searches for cheaper protective circuit boards or even omits this device, leaving the market flooded with lithium batteries that are at risk of exploding. Consumers cannot determine whether there is a protective circuit board from its appearance, so it is better to choose a reputable trader to purchase it.

If the mobile phone is equipped with a lithium battery, one charge frequent is actually good for the battery.
There is a saying: every cell phone battery has a fixed number of charging times. If charged too many times, it will accelerate battery aging and fatigue! This approach is actually only applied to nickel batteries. Lithium batteries are different. Frequent charging actually presents somebenefits for the battery. When a low battery prompt appears on your phone, you should start charging in time.
It turns out that cell phone batteries are "happier" if you charge them several times throughout the day rather than when they're dead. It's best to charge your phone when the battery is 10% exhausted. Obviously, this isn't practical for most people, so plug your phone into a charger when you can.
Recharging several times a day is a good habit. Not only does this help extend battery life, but it also keeps your phone charged throughout the day. Additionally, regular charging allows users to use features that are usually not used due to high power consumption, such as location-related features that usesenses the GPS (Global Positioning System) antenna of the smartphone.

Other misunderstandings about mobile phone charging:
1. Do not pay attention to the temperature when charging
In low temperature environments, the low temperature protection mechanism of lithium batteries will prevent chemical reactions of substances in the batteries, making it impossible to charge. charging or the charging speed will slow down. At high temperatures, lithium batteries will slow down. be unstable and even cause explosions.
2. New mobile phones must be activated
New mobile phones must use the power of the mobile phone and then charge it, and this must be repeated 3 to 4 times. This is called for activation. Previous cell phones required it, but today's lithium batteries no longer require it.
3. Play while charging
If conditions permit, it is best to turn off the phone while charging. This is the best maintenance for the battery. Playing with a cell phone while charging not only damages the cell phone battery, but is also harmful to the human body.
