Chapter 773: The real graphene battery comes out
Feitian Technology Research Center, test building.
In a laboratory, a black ink stick-like object with a length of 3 cm, a width of 2 cm, and a thickness of 3 mm is placed in a glass box.
"That's the thing?" Tang Xiaochuan asked with his back hunched and bent over looking at the black ink in the glass box.
"Yes!" Professor Gao put on his gloves as he said, opened the lid of the glass box, and took out the black ink stick from it.
Tang Xiaochuan took a closer look. There are metal electrode pads on one end of this thing. "You said it is a different kind of battery from solid-state batteries. I think this thing hasn't deviated from the shape of solid-state batteries!"
Professor Gao said: "It's called a graphene battery!"
"Graphene battery?" Tang Xiaochuan was taken aback, "is it a finished product?"
"Yes, it is a finished product!"
Tang Xiaochuan quickly took a pair of gloves from the side and put it on, then took the battery from Professor Gao's hand and observed it carefully. It looked dark and shiny on the surface, very light, and had metal electrodes on one side. It is the connector for charging.
"The idea of graphene as a battery is very topical on the Internet. Many netizens have discussed it, and many scientific research institutions have published research results related to graphene. Many domestic and foreign companies have already used graphene technology. It is used in related products, but the graphene battery made into this shape is really not found. Is this one used in mobile phones?"
Professor Gao replied: "Yes! In fact, many domestic and foreign companies have used graphene technology in display screens, sensors, transistors, desalination, hydrogen storage, aerospace, photoreceptors, composite materials, and biological research. field"
"Our company has previously used graphene technology in commercial fields such as liquid hydrogen storage, aerospace, sensors, photoreceptors, etc., but these are just the primary applications of graphene technology. Now our graphene has almost developed to the middle At the advanced stage, the graphene battery is the intermediate and advanced stage of this technology. If you conduct more in-depth research, you can touch the advanced technology field!"
Listening to Professor Gao’s introduction, Tang Xiaochuan asked while continuing to observe the graphene battery: "What is the difference between this thing and the solid-state battery produced by our new energy company?"
Professor Gao said: "Our solid-state battery is limited by materials and technology. We think it can be increased in size and power storage, but it cannot be further reduced. At least it cannot be reduced to be used as a mobile phone battery. But the graphene battery is different. Our current technology can make it the size of a mobile phone battery, and it has ultra-fast charging speed, ultra-large power storage capacity and fast heat dissipation that other mobile phone batteries do not have!"
Tang Xiaochuan asked: "How much storage capacity does this battery have and how fast is it charging?"
Professor Gao did not speak. He took a battery tester from the side and tested the graphene battery of Tang Xiaochuan's mobile phone. The device showed that the battery had very little power at this time, and it almost ran out of power. The capacity is 65500 mAh.
Tang Xiaochuan was surprised: "The capacity of this graphene mobile phone battery is so high? It's more than ten times higher than the current mobile phone batteries on the market!"
"Yes!"
Afterwards, Professor Gao put the battery on a professional charging instrument for charging, and the instrument showed that the battery level was rising rapidly.
From the beginning of charging, Tang Xiaochuan pressed the stopwatch on the watch.
When the green light on the professional charging instrument lights up, indicating that the charging is complete, Tang Xiaochuan immediately stopped the stopwatch. He took a breath of 192 seconds, and it only took more than three minutes.
"What is the voltage of this charging device?"
"30v, if we produce this kind of graphene mobile phone battery, the adapter charger will also use this voltage, with its 65500 mAh battery capacity, even the current mobile phone with the largest power consumption can support its uninterrupted use. It does not need to be charged for more than a day, and because of its super heat dissipation and heat conduction performance, when using it, you can't feel the phone will heat up at all!"
Tang Xiaochuan couldn't help but said with emotion: "Good things, good things!"
Professor Gao continued: "Moreover, we have tested its limit charging and discharging times. A typical mobile phone battery can be charged and discharged for almost six to seven hundred times, which will cause the performance of the battery to deteriorate. If it exceeds a thousand times, the battery will basically be scrapped. The best mobile phone battery can only be charged and discharged more than a thousand times, and our graphene battery can be charged and discharged more than 3,000 times, and the service life is more than three times that of the current mobile phone batteries on the market!"
Tang Xiaochuan has the final say, "If the mobile phone is equipped with our graphene battery, it can be used for more than three days with a single charge. I will charge and discharge 100 times a year, which means that the service life of our graphene battery is More than 30 years? Some charging times are not so frequent, it is estimated that it will last 60 or 90 years, right?"
Professor Gao nodded: "Almost!"
After hearing this, Tang Xiaochuan was a little bit dumbfounded, "Professor, I have to admire that you can improve the technology to this level. If a battery can be used for 30 years, wouldn’t it be too wasteful? What kind of mobile phones are available today? Thirty years of use? It takes three years at most to reach the end of its useful life. You can’t do that!"
"We use this durable technology in aerospace materials and equipment, but on the one hand it is too wasteful to use it on consumables such as mobile phones; on the other hand, it reduces our income in disguise!"
"If you think about it, other mobile phones have a battery capacity of up to 5,000 mAh, which can still satisfy everyone's use. Even those game-addicted gamers are enough. What do we want with such a large battery capacity? I think 10,000 mAh is almost the same. This can already be used for all the mobile phone batteries currently on the market! And the battery durability must be reduced. It can be used for up to four years and cannot be higher. This is all money!"
"However, this technology must be retained, and if you want to increase battery capacity and service life in the future, you can increase production at any time!"
Professor Gao reluctantly agreed: "Well, you are the boss, you have the final say! But... does graphene battery technology still need to be further studied?"
Tang Xiaochuan said immediately: "Of course, we must continue to study. Judging from the current degree of human use of energy, for a long time in the future, humans will be inseparable from the use of electricity, and graphene battery technology is the use of electricity. The most critical product!"
"Understood! I will let the battery research team weaken the capacity and service life of this graphene mobile phone battery. The target is 10,000 mAh and the service life is 500 charging cycles. The battery is affected by the environment, which may affect the battery's life. Life expectancy!" Professor Gao agreed.
Tang Xiaochuan asked: "Are there technical difficulties?"
"No, it is easy to do this. At least it can be done by appropriately changing the manufacturing technology and reducing some of the raw materials. I estimate that the finished product will be delivered to you in at most ten days!"
"That's great!"
