22 Years' Battery Customization

Lithium-ion cellphone batteries are present in most of our electronic devices. Laptop, smartphone or tablet, they are everywhere. Despite everything, this relatively old technology is not well known to the general public. So, in this article, let's talk more about cellphone batteries cost, explode reasons, and its overall life.
Cellphone Batteries Cost:
In general, you can expect that the cost of the cellphone batteries from $25 to $100. However, it depends on the model of the cellphone or services you will select.
Cellphone Batteries Explode:
You've probably heard of smartphone batteries explosions before? In recent years, several models have been affected by this phenomenon: the Galaxy Note 7, Galaxy S7 Edge, iPhone 6, 8, and Airpods. Most of the time, the explosion is due to overheating which causes combustion. This is called thermal runaway. Let's see in which cases, quite rare (compared to the number of phones sold each year), this risk can happen.
1. Overheating Due to High Temperatures:
Heat resistance depends on brands and models of phones. On average, it is estimated that they should not be exposed to temperatures over 40 ° or 60 ° C. You have to consult the instructions for use to find out.
If a smartphone reaches too high a temperature, you can still anticipate overheating by placing it in the shade. A lack of speed and the appearance of error messages can also put people off.
To check the battery temperature, switch to phone mode and enter the code * # * # 4636 # * # *. Battery information will be displayed, including its temperature.
Note that some insurance companies may reimburse a certain amount of the value of the phone in the event of an accident due to heat or short circuits.
2. Overheating Due to a Faulty Battery:
When the smartphone's processor is overloaded, for example, if you spend more than 30 minutes in a row playing a power-hungry game, the battery may overheat. It is therefore recommended to let it cool for a few minutes.
Some applications running permanently even when not in use can also participate in overheating. Better to close them before you start playing or shooting a video in direct sunlight.
3. Overheating Due to the Absence of a Fuse-type Component:
According to the experts, major phone manufacturers are planning to install a component that acts as a fuse to prevent the batteries from overheating. This prevents the device from charging and eliminates the risk of overheating. But to save money, some manufacturers do without, which increases the risk of overheating and therefore explosion.
4. Battery Overheating: Check the Condition of the Charger:
Sometimes the smartphone can overheat while charging, which is not normal. In this case, remember to check the condition of your charger because if it is damaged or patched, there is a risk of overheating which could lead to combustion.
Generally, we recommend keeping the original charger of the smartphone and the original cable, or of the same model.
Some Additional Tips:
Especially in summer or in hot weather, be careful not to place your smartphone in a place that is not sufficiently ventilated, suffocated under a mattress or a pillow, for example.
Do not attempt to repair the battery yourself, it may cause an explosion or inhale toxic smoke. In 2018 in Hong Kong, two employees of an Apple Store were repairing an iPhone when the battery exploded. They were not injured, but they breathed in the smoke that evolved and had to be hospitalized.
Finally, it is recommended not to wait until the battery is below 30 to 50% depending on the model, because lithium batteries charge less quickly and tend to overheat.
At present, the cases of smartphone explosions are mainly related to the elements that make up these lithium-ion batteries. But in October 2018, researchers claimed to have found a solution to store sodium ions. These sodium-ion batteries will be more efficient, more ecological because they consume less rare metals and are less unstable. They should soon be able to be marketed.
Cellphone Batteries Life:
Several reasons make li-ion a more advantageous technology: a higher capacity, a slower discharge, and the disappearance of the memory effect. Li-ion is more expensive to produce, however, and batteries are more prone to aging. Even if you don't use it for a few years, it will still lose a good deal of its capacity.
Li-ion batteries have a maximum number of cycles before which their range will begin to collapse. One cycle represents a complete discharge followed by a complete recharge of the battery. The advantage of li-ion is its flexibility: if you discharge your battery to 50% and then recharge it to 100%, this will be equivalent to 1/2 cycle knowing that current li-ion batteries have a lifespan of between 500 and 1000 cycles. charging. So, we can say that the average life of a cellphone battery is 2 to 3 years.
However, year after year, batteries manage to increase their capacity despite their size becoming smaller and smaller. But the power and uses of our mobile devices are no longer suited to current batteries. We are sure you regret your Nokia 3310 and its battery life of almost a week. Scientists and engineers have been looking for a successor to the li-ion for several years. Several avenues are being considered.
Researchers are also eyeing metals other than lithium, with higher energy density. This is the case, for example, with zinc, which is very abundant and inexpensive, which, when mixed with air, gives very good results.
Researchers have succeeded in creating a micro battery capable of recharging 1000 times faster than current ones.
What, for example, to insert one into a smartphone to have a reserve of energy capable of being recharged in a few seconds if necessary. Lithium-air would eventually replace lithium-ion. This would allow a very high energy density, but lower power.
If you’re wondering what to do with an end-of-life battery? It should not be thrown in the trash, lithium-ion batteries have dangerous metals that must be recycled.
