Generally, the temperature limit of 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 lithium batteries, there is nocurrently 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.
Detailed information:
1. First of all, there is no obvious ability. Batteries that do not have a clearly marked capacity (1000 mAh or 1000 mAh hours) may contain lower quality or recycled batteries. Many inexpensive batteries on the market are made from recycled batteries. Although theseBatteries are cheap, have a short lifespan and unstable quality.
2. Standby time is not guaranteed. Standby time refers to the duration of continuous use between installing the battery in the phone and the next charge. Generally speaking, the batteries sold in the market cannot guarantee standby time to customers because the battery quality is unstable. Many cheap batteries use poor quality battery cores, so the standby time is very short.
3. Whether a safety protection circuit board is installed. Without a protected circuit board, lithium batteries risk deforming, leaking and exploding. The market is flooded with exploding lithium-ion batteries, with companies seeking cheaper protective panels or abandoning them in the face of price competition. Consumers cannot discern panel protection fromof his appearance.
Reference materials:
First of all, the optimal operating temperature of lithium batteries is between 20℃ and 25℃. In this temperature range, lithium batteries perform best, and battery capacity and life can be maximized. When the temperature exceeds 25°C, the battery capacity decreases and the chemical reaction inside the battery accelerates, reducing its lifespan. When the temperature is lower than 20°C, the battery output power will decrease, and the diffusion rate of battery active materials will also slow down, affecting the battery performance.
In addition, I also want to remind you that under extreme temperature conditions, such as high temperature (above 60°C) or low temperature (below -20°C), the performanceand the safety of lithium batteries will be seriously affected. In a high temperature environment, the electrolyte will become unstable, which may cause dangerous situations such as overheating and battery explosion; In a low temperature environment, the reaction speed of the battery will be significantly reduced, which may lead to a sharp decrease in battery capacity. Therefore, try to avoid using lithium batteries in extreme temperatures to avoid safety risks.
