Chapter 96 The shock of friends and businessmen (bug fixes)
Monday, May 18th.
At about 16:00 in the afternoon, people from Xiaomi, Blue and Green Factory and a new energy vehicle manufacturer all came to Metaverse Intelligent Control today. They all came for solid-state lattice batteries.
They arrived at about the same time, so Lu An simply met them together.
After meeting, there were not many polite words and we quickly got down to business.
"Smartphone batteries currently on the market are generally between 1500 and 3000mAh, and the weight of the battery is about 50 to 80 grams." Lu An looked at Mr. Lei and several people from mobile phone manufacturers and said: "If it is replaced by a solid-state lattice battery, based on the weight of the battery of 65 grams, the fully charged power will be 0.065 kilowatt-hours."
Several heads of mobile phone manufacturers present knew that the energy density of solid-state lattice batteries was 1000Wh/kg and could calculate it, but they were still amazed when they heard this number.
Mr. Lei glanced at each other with several friends, then looked at Lu An and said: "The battery capacity of Xiaomi 4 is 3000mAh. The capacity of this solid-state lattice battery is equal to the battery capacity of 6 Xiaomi 4 batteries. This is incredible. It can definitely be called the most revolutionary technology in the battery field in the past thirty years. Breakthrough. ”
Then, the person in charge of vivo looked at Lu An and said: “That is to say, the capacity of a 65-gram solid-state lattice battery can reach 13,000mAh...”
Compared with the mainstream mobile phone batteries on the market today, it is more than six times higher.
After saying that, he couldn't help but let out an exclamation of exclamation.
Lu An immediately replied: "When the voltage is 5.0V, it is this number. If it is 3.7V, it is 17500mAh."
The mAh capacity corresponding to different voltages is different. The higher the voltage, the smaller the mAh value corresponding to the same amount of electricity. This is because mAh is the unit of current × time, which is inversely proportional to the voltage.
At first glance, 0.065 kilowatt-hour electricity does not seem to be much, especially according to the electricity price for household electricity. In China, 1 kilowatt hour of electricity currently costs 50 or 60 cents, and 0.065 kilowatt-hour electricity costs less than 4 cents.
But for a smartphone, 0.065 kWh is a huge amount of electricity.
You must know that the current battery capacity of smart phones is generally 3000mAh. At 3.7V voltage, it only has 0.011 kilowatt-hours of electricity, and 0.65 kilowatt-hours of electricity is equivalent to 6 times that of ordinary mobile phone batteries. One such solid-state lattice battery can hold up to 6 ordinary batteries.
Taking a mobile phone with a capacity of 3000mAh as an example, if used in the most power-consuming mode, such as running games at full frame rate, maximum brightness, and 4G full-speed networking, the battery will run out of power in about 5 hours at most.
When the battery capacity reaches 0.065 kWh, it means that the mobile phone can also be used in the most power-consuming mode and can be used for 30 hours.
With normal use, such as daily video browsing, social networking, and mixed use of calls, most smartphones with a 3000mAh battery capacity on the market can usually run out of power in 1 to 2 days.
But if it is powered by 0.065 kilowatt-hour, under normal use, the battery life can reach 6 to 12 days, which is equivalent to a full charge of the mobile phone and no need to recharge within a week.
If the mobile phone remains in standby mode, the 3000mAh battery can support the mobile phone's standby for about 7 days.
Supported by a solid-state lattice battery with a capacity of 0.065 kWh, the standby time can last for 42 days, which means that a full charge can last for nearly one and a half months.
This is what a seemingly inconspicuous 0.065 kilowatt-hour of electricity can do on a smartphone.
In other words, the advent of solid-state lattice batteries will greatly facilitate people’s daily lives, and many electronic products will undergo earth-shaking changes.
This is the civilian version of the solid-state lattice battery that has reduced its energy density by two-thirds. If it were 3000Wh/kg, it would be even more incredible.
Finally, Rebus looked at Lu An and couldn't help but ask: "What is the number of charge and discharge cycles of this solid-state lattice battery?"
Lu An replied: "Usually around 300 to 500 times, theoretically it can reach 800 times. The number of charge and discharge cycles is similar to the batteries on the market today."
Another person in charge of a mobile phone manufacturer looked around at the people present, and then exclaimed in amazement: "But this battery has a high energy density, which is amazing in this calculation. I calculated a mobile phone's service life of 5 years. It can last 12 days with normal use after a full charge. In 5 years, it only needs to be charged 150 times."
Everyone was also amazed, and Mr. Lei couldn't help but burst out: "This is really outrageous. It takes 5 years to charge 150 times, and 500 times of charging and discharging can last for more than 10 to 15 years..."
Hearing this, Lu An smiled and said, "That's not the case. Before 500 charge and discharge cycles are completed, other components in the battery will have been scrapped. The cost of replacing other components is higher than building a new one. The normal service life of a solid-state lattice battery is about 8 to 10 years."
Those present couldn’t help but nodded. Yes, other components in the battery also have a lifespan. The service life of the entire battery cannot be measured simply based on the number of theoretical charge and discharge cycles.
But a life span of 8 to 10 years is quite an exaggeration.
The normal service life of today's smart phones is only two or three years, and about five years at most
When the mobile phone is scrapped, the old battery inside can be replaced with a new phone, and the new phone is used until it is scrapped, and the old battery can still be used for a while.
In the future, there will definitely be high-price recycling of second-hand smartphones. If the mobile phone is recycled, the solid-state lattice battery inside has not been artificially damaged. Someone will definitely recycle the battery separately and reuse it in a new mobile phone.
Lu An looked at everyone and smiled and said: "When used in smart phones, the number of charge and discharge times of solid-state lattice batteries is less than 30% to 50%, but if used in more power-consuming products, the number of charge and discharge times will not appear to be too redundant."
“For example, private cars of new energy electric vehicles, or even large trucks that consume a lot of electricity, for such large power consumers, they will definitely be able to use up the number of charge and discharge cycles when the battery life is used up. Our technical team also designs according to the large power consumers.”
No matter what, the emergence of solid-state lattice batteries is definitely an innovative technology that can change the world and many industries.
What is certain is that the advent of solid-state lattice batteries will definitely promote the electrification of large trucks.
There will definitely be car companies launching such products, such as Elon Musk’s Tesla Motors, which has long been promoting the electrification of large vehicles.
If nothing else, today's large truck drivers have a pain point, that is, they have a headache when facing "gas guzzlers".
The truck stopped at a service station to rest or have a meal. When he came back, he found that the fuel tank cap was open. When he got closer, he saw that the fuel he had just filled had been stolen. He blacked out and fainted on the spot.
Many truck drivers are trying their best to prevent "gas guzzlers". Some of them weld cages for the fuel tanks, and some keep dogs to watch the tanks.
But if this truck is electrified, it no longer burns oil but uses electricity.
The pain point of guarding against "gas guzzlers" will disappear immediately. If all trucks are electrified, or electric large trucks become mainstream, then "gas guzzlers" will naturally disappear. This is inevitable.
Just as thieves gradually disappeared after the popularity of smart phones and online payments, everyone went out without a wallet, and thieves had nowhere to use their unique skills.
Finally, Mr. Lei and other major manufacturers present began to inquire about solid-state lattice batteries.
Lu An said in an orderly manner: "The specific application scenarios of solid-state lattice batteries have not yet been determined, but mobile consumer electronics is also an important business direction of Metaverse Intelligent Control, and the specific price will not be announced until later."
"A rough estimate, based on a mobile phone battery capacity of 17,000 mAh, the price will not be lower than the unit purchase price of 2,000 yuan." As soon as these words came out, several mobile phone manufacturers present were stunned.
Rebs immediately said: "Not less than 2,000 yuan? How can it be so expensive? Our Mi 4 mobile phone launched by Xiaomi last year was only priced at 1,999 yuan. This solid-state lattice battery costs 2,000 yuan to purchase. No mobile phone manufacturer can afford such an expensive price. "
Several other mobile phone manufacturers agreed. If the purchase price is such an expensive one, Xiaomi will definitely be out of business. Not only Xiaomi, but all mobile phone manufacturers present cannot afford it.
Normally, the battery cost of a mobile phone accounts for about 15% to 25% of the total cost of the phone.
Even Apple cannot afford such an expensive battery cost.
Everyone's reaction was as expected by Lu An. He said calmly: "The production cost of solid-state lattice batteries is high and the price will not be low. However, the purchase price of 2,000 yuan I mentioned is for an energy density of 1,000Wh/kg."
Everyone looked at Lu An after hearing this, and the latter continued with a smile. Said: "Talk about the smart phone market alone, my personal opinion is that using a solid-state lattice battery with an energy density of 1000Wh/kg is too luxurious and wasteful. One charge is 0.065 degrees, which is a serious excess of power for a smart phone." Hearing this, Mr. Lei couldn't help but said: "Brother Lu, what do you mean?"
Lu An smiled and said: "If you cut down the capacity or the energy density, either alone or both, the cost of technology downgrading will also be reduced. 17,500 mAh will not be used at all. A 10,000 mAh capacity is completely enough." This is an unprecedented improvement in user experience, and it also avoids excess power and reduces costs."
As soon as this was said, everyone's eyes lit up, and a manufacturer representative asked: "Can this be done?"
Lu An replied affirmatively: "Of course it can."
Then, Lu An smiled and said: "Actually, the 1000Wh/kg energy density version of the solid-state lattice battery is not suitable for mobile consumer electronics applications. It is more suitable for new energy electric vehicles." g range. "
"The production difficulty can be reduced, the production capacity can be greatly increased, and the cost can also be greatly reduced."
Hearing this, Rebus immediately asked: "What is the estimated price of this so-called Beggar's Edition?"
Lu An replied: "The estimated unit price of the purchase is in the range of 800 to 1,000 yuan, which can be reduced by at least half."
Compared with the high purchase unit price of 2,000 yuan quoted by Luan before, the minimum price of 800 yuan is already a cost reduction of -60%.
This price is still not cheap for a smartphone that costs 2,000 yuan, accounting for more than one-third of the total cost.
But it can indeed make the smartphone industry affordable, such as high-end flagship models.
Leave aside other manufacturers, Apple will definitely be able to hold on, because Apple’s current mobile phone battery costs are in the range of more than 700 yuan.
Lu An obviously asked his subordinates to conduct research on the smartphone industry when making such a quotation.
