In just one day, all 30 million semiconductor refrigeration chips stocked by Xinghai Group were sold out, with operating income of 1.5 billion yuan.

This is beyond Mu Yang's imagination. These clothing factories are really crazy about ordering goods. It feels like whoever gets the goods first will seize the new clothing market first.

Xinghai Group had to announce: 30 million semiconductor refrigeration chips have been sold out, and the next supply time will be New Year's Day. Pre-orders will not be accepted, hoarding is prohibited, and speculation is prohibited.

Next time, you may not be able to buy the goods at the clothing factory whose initial rush-buying volume is too large.

Muyang’s focus is still on the battery project.

The biggest problem with ternary lithium batteries is safety.

In later generations, the spontaneous combustion incidents of new energy vehicles that everyone is most concerned about are as follows: there are collisions and compression fires, there are scratches on the bottom of the car that hit the battery and fires, there are high temperatures and out-of-control fires, there are fires when charging, and even when the car is parked in a parking space.

There were unprovoked fires, and there were short circuits due to flooding...

For example, a celebrity's Tesla hit a telephone pole and the car started to smoke. At this time, rescue must be carried out quickly. Don't think that just a little smoke is okay, and don't think that you can put it out with a fire extinguisher.

The battery pack is sealed, and a fire extinguisher cannot extinguish the inside of the battery. This is different from the situation where an open fire ignites. If a battery is damaged, it may be short-circuited, which will quickly cause a chain reaction.

At this time, if the car door is stuck, quickly pry the door or break the glass to save people, let alone use water to extinguish the fire.

Can water extinguish electricity and cause fire?

The manufacturer must say that the battery safety is okay, and it is impossible for the higher-ups to kill new energy vehicles with a stick. Isn't this a slap in the face?

We can only improve the quality of batteries. Many battery manufacturers conduct experiments that are much stricter than national standards.

Mu Yang is relatively clear about these issues, so he attaches great importance to battery safety issues.

At present, new energy vehicles have not yet emerged, and the country has not yet issued development and testing standards for ternary lithium batteries for new energy vehicles, or the requirements are not strict.

Then, Xinghai Group will formulate its own standards, publish the standards after passing them, and recommend that the country implement these standards.

Xinghai Group has set the threshold for entering new energy batteries to be higher, digging a hole for itself, but also for its competitors.

When a ternary lithium battery is damaged, it is easy to catch fire.

For example, the external factors in the test standards refer to the fact that the battery of a new energy vehicle will deform, pressurize, or heat up after being subjected to pressure from external stimuli, and thermal runaway will occur, leading to spontaneous combustion and explosion.

To this end, the Xinghai Group Automotive Research Institute must simulate the most extreme situations in a collision, such as acupuncture tests, squeeze tests, drop tests, airgel insulation effect tests, battery pack vibration tests, etc. Only these tests passed

, in order to ensure the safety and stability of batch product batteries.

For example, the acupuncture test that is often heard in later generations refers to using a steel needle to pierce the battery pack to simulate a car encountering an extreme collision, causing the battery core to be punctured and the battery to be short-circuited.

The qualification standards for the national acupuncture test are: under the conditions that the battery pack test temperature is greater than 0 degrees and the SOC (remaining capacity of the battery) is >95%, there will be no fire or explosion within 5 minutes.

Xinghai Group’s acupuncture test requirements are: no fire, no explosion, and no heat diffusion.

Drop test, the future national standard requires that the electrolyte will not leak, fire or explode after being dropped from a height of 1 meter;

Xinghai Group requires that there will be no abnormality if dropped from a height of 3 meters.

It can be said that the testing standards of Xinghai Group are two or three levels higher than those of future countries.

If it is formulated in accordance with national standards, it is estimated that many people will die due to accidents caused by battery safety issues in one year.

As long as the country agrees to adopt Xinghai Group's battery testing standards, or even offers a 20% discount, in the next few years, many battery manufacturers will not be able to jump over this threshold, and will also block many competitors.

By that time, there will definitely be many battery manufacturers, including overseas battery manufacturers, who will shout: I can’t do it!

In this way, Xinghai Group's battery technology licenses will be better sold and more valuable.

In the past few days, Mu Yang went to the electrolyte project team to help solve problems. Today he went to the battery pack project team of the battery project team to check the situation.

A battery pack, in layman's terms, is a box of cold and cold capsules. There are many rows of capsules inside. Each row is a battery module, each capsule is a battery, and the outer box and capsules are the outer and inner protective packaging. However, this battery

There are many battery modules and batteries in the bag, and the number is determined by the designed battery capacity, such as 70 kWh or 100 kWh.

Mu Yang walked into the battery pack project team. The working environment of this project team is not as strict as the electrolyte laboratory. When the employees see the chairman, they say hello and continue working. If there are extremely difficult problems, hurry up while he is there.

ask.

Battery thermal runaway is one of the problems inside the battery pack.

In order to prevent thermal runaway, the Xinghai Group platform adopts seven core battery thermal management technologies from modules to entire packages, raising battery safety to a new level.

The seven-layer core battery thermal management technology is first of all heat insulation technology. The heat insulation wall between the battery cells is made of thickened nano-scale aerospace material aerogel. In addition, the multi-layer designed fire blanket and anti-arc design can effectively reduce the electricity consumption.

Heat transfer between cores, as well as heat and high-temperature gas transfer to the interior of the vehicle.

This is designed like the watertight compartments of some ships. Even if a certain place is damaged and water leaks, if it is blocked in time, the water will not affect the entry of other cabins. The Titanic also has a watertight compartment, but its watertight compartment does not

It extends to the top and is not completely sealed. It will still extend to other compartments after it is filled with water.

Xinghai Group’s battery rooms are individually sealed and insulated.

In this way, even if a problem with one battery cell does not cause a large-scale chain reaction, the system can handle it more simply and efficiently.

In addition to the safety considerations inside the battery pack itself, Xinghai Group's battery packs are also equipped with an ultra-high-strength "new battery physical protection architecture" on the outside to fully protect battery safety from the outside.

This protective structure adopts a new generation of high-strength tic-tac-shaped structure battery shell (better rigidity), which is reinforced with multiple 1500MPa ultra-high-strength steel beams. The upper cover assembly uses 1500MPa super-strong side protection beams, and the tray assembly

Using the company's self-produced aluminum alloy 7090 bottom protection with a strength of 1000MPa (for reference, the steel strength of submarines and tanks is about 800-1000MPa), the extrusion resistance of the entire package is three times that required by future national standards.

If the 01 and 02 models are used in the future, the company's self-produced titanium alloy TC4 will be used, and after laser heat treatment, the strength will reach 1600MPa+, which is lighter and stronger.

The project progress has not yet progressed to the large-scale assembly of battery packs, but once the electrolyte problem is solved, individual batteries can be produced.

A single battery is not light either, and the battery pack takes up a lot of weight.

[For example, Wei Lai's 100-degree battery pack has a single cell energy density of 206Wh/kg. The battery pack adopts a CTP structure and the battery pack energy density is as high as 186Wh/kg. The weight of the battery pack is 100*1000/186=537KG. Double

The motor has 435 horsepower and can travel 605KM. The curb weight is 2280KG (including battery pack and body 1743KG).]

The body of the Hummer EV uses aluminum alloy on a large scale. Although the body size is large, the dual-motor model is lighter to 2.1 tons than the 2.79 tons designed in later generations.

Xinghai Group's new battery technology, the energy density of a single cell is over 260Wh/kg, the battery pack adopts the future Kirin battery structure, the energy density of the battery pack is as high as 234Wh/kg, the low version has a range of 600KM, and a dual motor 625 horsepower design, it takes about

With 160 kilowatt hours of electricity, the battery pack weighs 683 kilograms, and the vehicle weight reaches 2,783 kilograms.

If it is designed according to the high version's 800KM and three-motor 830-horsepower design, it will require about 200 kilowatt-hours of electricity, the battery pack will weigh 854 kilograms, and the vehicle weight will reach 3,000 kilograms.

Generally speaking, Xinghai Group’s batteries are advanced in battery pack structural design, electrolyte, energy density and charging technology.

As soon as he was born, he was number one in the world.

It is a bit ahead of the ternary lithium battery technology for new energy vehicles on the market in 2022, but it still has not been able to break through to black technology.

The technology of Level 7 reading system is still far from black technology.

But to the outside world, perhaps Xinghai Group's technology can already be regarded as black technology.

a few days later,

It’s ten o’clock in the morning on December 5th.

Mu Yang is going to meet two people.

Sun Yi and Ma Yun.

That’s right, Sun Yi from SoftBank and Ma Yun from Alibaba.

The first batch of Alibaba employees will not actually settle in the Xixi Valley Alibaba Center until 2017, but Ma Yun announced her arrival in H City in 2000.

Xinghai Group and Ali have been neighbors for a few years. Mu Yang originally wanted to refuse the visit of the two of them. He didn’t want to guess and knew what they were doing when they came, but there was nothing he could do to meet and chat, but when it came to buying shares in Xinghai Group, etc.

Definitely not.

They are all high-level figures, and it is inevitable that they will meet a lot at those economic conferences in the future. If they directly slap Ma Yun in the face now, it will be very embarrassing for both parties to meet in the future.

In 1999, starting from the second round of financing of Ali Baba, Sun Yi appeared and has continued to support Ma Yun since then. He successively invested 80 million US dollars in Ali Baba, accounting for 34.4% of the shares. It must be said that Sun Yi is very lucky.

Not long ago, Mu Yang rejected a visit from Roach, chief economist at Mogenstan Stanley.

Sun Yi probably knew that if he visited Mu Yang, he would be rejected mercilessly by Mu Yang, so he asked Ma Yun to be the middleman, thinking that it was easier for Chinese people to talk to each other.

In fact, Ma Yun also wanted to meet Mu Yang and get acquainted with him, so she just took this opportunity to refuse Sun Yi, so let's visit together. She had spoken to Mu Yang before coming.

In terms of wealth, Mu Yang beats Ma Yun by a huge margin;

Alibaba's current market value is about 8 billion US dollars, which is incomparable with Xinghai Group. Muyang's investment company also invests in Alibaba's shares, which is why Muyang is willing to meet Ma Yun.

Mu Yang can't say he hates or likes Ma Yun, because they are in different industries, which does not affect his money making, and from the current point of view, it does not interfere with his interests.

From a business perspective, they are indeed very powerful;

When it comes to sarcastic words, Mu Yang feels that he really can't beat Ma Yun. This guy relies on this for a living.

As for the others, Mu Yang didn't bother to comment.

The height that Mu Yang is currently standing at is different from that in his previous life, and the things he can see are different, and his mentality is different, so Ma Yun called him. Mu Yang didn't have any surprise or anger, just a little surprised, and then returned to calmness and equality.

comminicate.

The two came to Xinghai Group in a low-key manner, unlike Luo Qi's high-profile visit.

Now, Mu Yang often goes to the laboratory building. His office has been moved to the second floor of the supercomputing center at the headquarters base and will be moved into Xinghai Building after the Xinghai Building is renovated.

Other administrative departments are temporarily located on the first floor of the supercomputing center, high-rise and R&D center offices are temporarily located on the second floor, and most R&D personnel work directly in other experimental buildings.

The supercomputing center has a single floor area of ​​5,000 square meters and a total of 10 floors. The real supercomputing center is located on the 9th floor.
