Why Lithium-Ion Batteries Explode?
Why Lithium-Ion Batteries Explode?
Battery problems on brand-name phones are relatively rare and are more common in refurbished or second-hand phones. 2. To save costs, mobile phones or refurbished machines often choose batteries with lower-cost performance in mobile phone equipment. These batteries are low cost, have too many impurities, have a poor planning process, and risk self-destruction.

Talk about the difference between lithium battery and storage battery.
Difference between the battery and lithium-ion battery; Prices vary. Lithium-ion batteries are expensive; Safety performance. High battery safety; Use time is different. The service time of a lithium-ion battery is relatively long.; Lithium-ion batteries are better than batteries. Although most electric vehicles now use batteries because of price problems, lithium-ion batteries can completely replace lead-acid batteries.

Failure classification and cause analysis of lithium battery.
Failure classification and cause analysis of lithium battery.
1、 Capacity decay failure
During the standard cycle life test, the discharge capacity shall not be less than 90% of the initial capacity when the number of cycles reaches 500. Or when the number of cycles reaches 1000, the discharge capacity shall not be less than 80% of the initial capacity. If the capacity drops sharply within the range of standard cycles, it belongs to capacity attenuation failure.

Difference between 26650 lithium batteries and 18650 lithium batteries？
The battery life of the 18650 lithium-ion battery and 26650 lithium-ion battery must be different because the two models are named after size, 18650, that is, straight 18mm and height 65mm. From this point of view, 26650 must have a larger volume ratio than 18650, so there is a larger space-filling material to achieve a larger capacity. At present, the capacity of 18650 is 220026003100mah, while the capacity of 26650 is generally 40004204500mah, The lead-in endurance will be longer.

What are the reasons for the bulging of lithium batteries in electric vehicles?
Battery is the core component of electric vehicle. The word "lithium ion battery" is familiar to motorists. In recent years, the phenomenon of battery bulging is common, which makes many consumers very distressed. Because once there are individual battery bulges in a group of batteries, the whole group of batteries must be replaced.

What effect does the overcharge of lithium batteries have on performance?
1) In the polarization phase, the voltage of the battery rises rapidly after the current is applied due to the existence of polarization, and the temperature of the battery decreases at this time;
2) After 240s, the battery enters the stage of stable temperature rise, in which the battery temperature rises at the rate of 0.05 ℃ /min;
3) During the temperature stabilization phase, the battery temperature will continue to rise, but the battery temperature will not rise.

Will the production of lithium batteries cause environmental pollution？
positive and negative current collectors. Aluminum foil is used for the positive pole, copper foil is used for the negative pole, and some nickel strips may be welded for connection and conduction. These are non-toxic. Now some waste lithium-ion battery recycling units make money by recycling these and steel and aluminum shells. Recyclable and pollution-free.

18650 lithium battery pack with large internal resistance or small internal resistance?
Is the internal resistance of 18650 battery pack large or small? Resistance indicates the resistance of a circuit element to current transmission. The unit is Ohm. The internal resistance of 18650 battery pack is related to the capacity and type of battery. Generally speaking, the larger the capacity, the smaller the internal resistance. For batteries with the same capacity, the internal resistance of the multiple type is smaller than that of the capacity type. The internal resistance of a typical lithium battery pack is only a few milliohms.
