Q:
Will high temperature lithium batteries explode?
A:
High temperature lithium batteries have a certain risk of explosion, but not all high temperature lithium batteries will explode.
The safe use temperature of lithium batteries is between 20 degrees Celsius and 60 degrees Celsius. Using lithium batteries
in a high temperature environment may trigger a chemical reaction inside the battery, resulting in the release of chemicals
inside the battery, thus increasing the risk of battery explosion.
However, most lithium batteries can still be used safely even at high temperatures. In order to ensure the safe use
of lithium batteries, you need to pay attention to the following points during use:
Avoid exposing lithium batteries to high temperatures for long periods of time, such as prolonged exposure to the hot sun or use in airtight electronic product cases.
2. Avoid mixing lithium batteries of different brands, specifications and capacities, as this may lead to short-circuiting
of the battery management chip, thus triggering an explosion.
3. Avoid overcharging or over-discharging during use, which may damage the battery management chip and increase
the risk of battery explosion.
4. In the process of using the battery should be kept well ventilated and heat dissipation, to avoid overheating of the battery.
In short, high-temperature lithium batteries have a certain risk of explosion, but as long as they are used correctly and cared for, this risk can be reduced.
Q:
What is the auto repair function of low temperature lithium battery?
A:
The automatic repair function of low temperature lithium battery means that the battery can still work normally in
low temperature environment and can be repaired automatically when failure occurs. This function is very important
for electronic products used in extreme environments, such as outdoor equipment in cold regions, automotive
electronics, spacecraft and so on.
The main principle of the low-temperature lithium battery auto-repair function is to add a special chemical substance
inside the battery in order to increase the conductivity of the battery in a low-temperature environment so as to
improve the efficiency of the battery. At the same time, this chemical substance can also be in the battery failure,
automatically repair the battery damage, to ensure the service life of the battery.
In conclusion, the low temperature resistant lithium battery auto-repair function is a technology that improves
the efficiency and lifespan of batteries in low temperature environments through special chemicals. This technology
plays an important role in improving the performance and reliability of electronic products and is widely used in various fields.
Q:
There are several welding methods for lithium batteries?
A:
Lithium battery welding methods are mainly the following:
Laser welding: laser welding uses a high-energy laser beam to irradiate on the battery cell, causing it to melt to form a welded joint. This welding method can realize efficient and precise welding, and will not cause thermal damage to the battery.
2. ultrasonic welding: ultrasonic welding uses high-frequency vibration energy to weld the battery cells together.
This welding method can realize efficient and precise welding, and will not cause thermal damage to the battery.
3. Resistance Welding: Resistance welding utilizes high voltage, low current electrical energy to generate heat through
the welding electrodes, melting the battery cells to form a welded joint. This welding method can realize efficient and
precise welding, but may cause thermal damage to the battery.
4. Laser spot welding: Laser spot welding utilizes a high-energy laser beam to irradiate the battery cells, causing them
to melt and form a welded joint. This welding method can realize efficient and precise welding, and will not cause thermal
damage to the battery.
In short, the welding method of lithium battery needs to be selected according to different product requirements and
material properties. When selecting the welding method, it is necessary to take into account the welding quality, production
efficiency, cost control and other factors.
