When it comes to Apple, the publisher of the iPhone series of mobile phones, we have to mention another old rival with Apple and Apple's products - Samsung.

And use Apple's exclusive IOS operating system does not use, Samsung mobile phones use the open source Android system, for those who do not like the IOS system, Samsung series of mobile phones is quite a good choice, in China those cheap domestic brand influence has not been expanded, Samsung mobile phones once reached a situation of competing with Apple.

However, just when Samsung's mobile phone was gaining momentum, an accident that shocked the world made it fall into crisis for a while, and this accident was often talked about decades later - that is, the "Samsung note7 explosion".

Samsung Galaxy Note7 is an Android smartphone released in August 2016, but in less than a month after the release of Note7, there were more than 100 explosions around the world, according to the investigation, the explosion was due to the quality of the lithium battery built into the note7.

Lithium battery is a thing that can be seen everywhere in life, due to its advantages of long life, large capacity, low cost, etc., it is widely used in various products, up to NASA's Mars rover, down to the electronic products that can be seen everywhere in the hands of ordinary people, lithium batteries are almost everywhere.

However, if the voltage of the lithium battery is too high, or the instantaneous current is too large due to a short circuit in the battery, it will cause a large amount of heat and gas to accumulate inside the lithium battery in a short period of time, causing an explosion.

In addition to these two methods, there is a more simple and crude way to make a lithium battery explode, that is, to directly heat it to a temperature of more than 300 degrees Celsius.

When the Note7 explosion occurred, a large number of memes appeared on the Internet, so much so that during that time, the Note7 mobile phone was almost equated with a grenade.

Of course, the power of a lithium battery explosion is definitely much weaker than that of a grenade, but ...... What if a hundred, two hundred, or more lithium batteries explode together?

Quantitative change leads to qualitative change, and this is not just talking......

When Qi Lin mentioned the digital product counter, Cheng Yanqiu had already guessed his thoughts, and immediately took Qi Lin to the area located in the northeast corner of the third basement floor.

Almost all of them are counters selling personal electronics – all kinds of mobile phones, tablets, laptops, and of course, including the famous Samsung and Apple counters.

Of course, the largest counters are still those domestic brands of Huaxia, in the process of catching up for decades, Huaxia mobile phones have surpassed Apple, which was almost the leader in the mobile phone industry, in terms of performance and quality, and has become the world's most selling mobile phone.

"Find all the spare lithium batteries in the store and pile them together, we have to make a big enough battery bomb!" Qi Lin said.

Those batteries installed in computers or mobile phones, even if they are not turned on, the automatic discharge has exhausted the stored power in them, but those spare lithium batteries that are stored in a semi-charged state, even after three or five years, can still maintain a considerable voltage.

What Qi Lin needs is these lithium battery blocks that have not been completely scrapped.

Fortunately, before those evacuees poured into the underground shopping mall, the domestic signal base stations had stopped serving the civilian frequency band, so these digital products were not looted and destroyed, only a few counters were smashed.

Soon, palm-sized mobile phone batteries and long strips of laptop batteries were piled up into a hill more than half a meter high, and Qi Lin found a few large shopping bags and packed all these batteries into them.

Once before the war, Qi Lin watched a video of a lithium battery overcharge experiment, which was a 50,000 mAh battery, at the moment of the battery explosion, the plywood wall close to the battery was directly blown through a hole, and the glass window on the other side was all shattered, and half of the room was smoked black.

Although the capacity of laptop batteries and mobile phone batteries is only a few thousand milliamps, the power of hundreds of them together should not be underestimated.

After packing all the batteries in the shopping bag, Qi Lin ran to the counter, found a few cardboard boxes for shipping packaging, tore the cardboard boxes apart, and then stuffed the scraps into the gap between the batteries.

Qi Lin and Cheng Yanqiu carried two big bags and returned to the second basement floor again.

"I'll count three, let's rush in together, rush in front of that sarcoma and throw the fuse on it, then turn around and run, even if it can't be blown up once, then blow it up a second time, anyway, there are still many batteries below." Qi Lin said to Cheng Yanqiu.

"Three, two, one, rush!"

As soon as Qi Lin's words fell, the two of them rushed towards the location of the sarcoma with four stuffed shopping bags, quite like those aunts and aunts when the supermarket price was slashed.

As soon as they stepped on the flesh membrane, the blood bubbles on the flesh membrane began to swell again, but the two of them didn't look at it, so they rushed forward with their heads in one breath.

The strange sarcoma reappeared in Qi Lin and Cheng Yanqiu's field of vision, and the two took out the lighter, lit the fuse in the shopping bag rubbed out of cardboard and cotton wool, and then threw the shopping bag towards the sarcoma.

With a few muffled sounds, four shopping bags filled with batteries landed firmly underneath the sarcoma, and the fuse quickly burned in, and a puff of pungent smoke began to rise from inside.

"Run!"

The two didn't say a word, turned around and ran!

"Bang!" Qi Lin had not gone far when a muffled sound came from behind him, followed by a series of crisp or dull explosions, as if a string of firecrackers had been ignited.

Qi Lin glanced back and saw that a large number of batteries were scattered, and less than half of them successfully exploded, and they did not cause much damage to the sarcoma.

"Damn, you forgot such an important thing!"

Qi Lin only remembered at this time that the capacity, brand, specification and even material of these batteries are completely different, and the power and time of the explosion are naturally very different, and the premise of wanting to cause heavy damage to this sarcoma is to establish the condition that all the batteries explode at the same time, but now, the battery that exploded first directly blew up the other batteries, and the batteries behind either failed to be detonated, or exploded several meters away from the sarcoma, which was completely unable to achieve the desired effect.
