The temperature range of the lithium battery is as follows:
1. Charging temperature range: 0℃ to 45℃.
2. Discharge temperature range: -20℃ to 60℃.
3. Optimal operating temperature: about 10℃ to 35℃.
4. It should be noted that different types of lithium batteries may have different temperature limits. For example, low-temperature polymer batteries can operate at lower temperatures, down to -40°C, while some specially designed lithium batteries can even operate normally in extremely high or low temperature environments. Additionally, lithium batteries should be used with extreme caution at high temperatures to avoid the risk of overheating, combustion or explosion. Therefore, when using lithium batteries, proper precautions must be followed to ensure that they worksafely and reliably.
The temperature limit of general mobile phone lithium batteries is 40 degrees Celsius, 40-60 degrees Celsius. If the time is not too long, there will be no problem. Lithium batteries can also be specially customized to withstand high temperatures, and their high temperature performance will be much better.
The temperature limit set for cell phone lithium batteries is generally 40 to 60 degrees. Batteries are generally marked with explosion-proof valves, and high temperature resistant lithium batteries can withstand temperatures of up to 800 degrees. Generally, lithium batteries are tested to withstand high temperatures of 200 degrees, 500 degrees and 800 degrees, but they are generally not exposed to such high temperatures in daily life.
For batterieses lithium, there is currently no clear theory in the industry to support the inevitable relationship between internal resistance, discharge platform, life, capacity, etc. under various temperature performance. Calculation formulas and relevant mathematical models. are still under study. Generally speaking, lithium batteries are not sensitive to temperatures between 0 and 40°C. However, once the temperature exceeds this range, the lifespan and capacity will be compromised.
In order to ensure the lifespan, safety and reliability of lithium batteries, advanced protection management systems are used in high temperature resistant lithium battery packs to prevent overcharging , overdischarge, high temperature operation and low temperature. temperature load or short circuit is damaged or even causes problemsof security.
Detailed information:
Be sure to pay attention to the following points when 'purchase.
1. Is the capacity clearly marked? Batteries without clearly marked capacity (such as 1000 mAh or 1000 mAh) are most likely using lower quality batteries or recycled batteries. Many inexpensive batteries on the market are made from recycled batteries. Although they are cheap, their lifespan is short and their unstable quality can damage the phone.
2. Is there guaranteed standby time? 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. This is because the battery quality is unstable. Of manyThese cheap batteries use poor quality battery cores, so the standby time is very short.
3. Whether to install a safety protection circuit board. Without a protective circuit board, the lithium batteryThere is a risk of deformation, leakage and explosion. 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.
