Technology overlord starts with new energy vehicles

In the live broadcast room, according to the process, Feng Hao started the live broadcast process of the first item today, and popularized information about sodium-ion batteries for everyone.

"I won't talk nonsense. Our first task today is to introduce the sodium-ion battery technology that many people don't know much about."

"Speaking of batteries, in daily life, everyone should have heard of various battery technologies and can come into contact with various batteries."

"First of all, dry batteries are the most common, a chemical battery that uses paste electrolyte to generate direct current. Dry batteries are disposable batteries that are widely used in daily life, such as radios, walkmans, remote controls, flashlights, toys, etc. On top of the small appliances."

While talking, Feng Hao took out a few batteries from his pocket and displayed them on the screen of the live broadcast room.

"The common dry battery is a zinc-manganese battery, which is the most common and most accessible battery."

"But this kind of battery has many disadvantages, such as not being able to be recharged, the battery capacity is small, and so on."

Throwing the dry battery in his hand aside, Feng Hao turned around and picked up a heavy battery from the small cart next to him.

"Then there is another common battery, lead-acid battery, which can be charged and discharged, and has a larger battery capacity, but it also has many disadvantages, such as huge volume, poor battery cycle performance, and strong attenuation in cold regions."

Putting the lead-acid battery in his hand back on the trolley, Feng Hao picked up another battery.

"And with the development of battery technology, all kinds of lithium batteries have begun to appear!"

"Unlike ordinary lead-acid batteries or dry batteries, lithium batteries have a higher energy density.

Compared with lead-acid batteries, it can store more electricity under the same volume, and has better cycle performance. It is a relatively complete battery technology.

Nowadays, in terms of lithium battery technology, Hengxin Battery Company can be said to be the first echelon, or a unique existence!

The lithium iron phosphate battery produced by our factory, after continuous technical research and development, is far superior to other ternary lithium batteries, polymer batteries and so on from the initial safety performance.

Up to now, whether it is the number of battery cycles, energy density, or high and low temperature performance, etc., our lithium iron phosphate batteries are much better than ordinary lithium batteries. "

"But this kind of battery, although all aspects of performance can already meet the use of cars and the use of battery replacement technology."

"But even the lithium iron phosphate battery produced by Hengxin Battery Company still has some fatal shortcomings."

"The most important thing is the scarcity of lithium resources, which makes lithium-based batteries unable to be manufactured and applied on a large scale, and the production cost is high."

"Many people now know the difficulties faced by Kyushu Automobile. The price of raw materials for lithium iron phosphate battery production has soared. Industrial-grade lithium carbonate has increased from 30,000 yuan per ton three years ago."

"The battery production of Kyushu Automobile has doubled in the past few years and the price has increased to 60,000 yuan per ton."

"Now the price has reached an incredible height. In just one month, it has risen to 830,000 yuan per ton!"

"This is a price that is extremely inconsistent with the laws of the market. As for the forces with funds and strength that can cause all this, everyone should have been able to guess it."

"However, the good news is that Kyushu Motors has already anticipated this situation, and the solution is sodium-ion batteries."

"Industrial-grade lithium carbonate resources can only be produced into the lithium iron phosphate batteries we use today, which are very rare."

"As for sodium-ion batteries, there are not many ores in nature, but sodium is a very common element in our lives, and its extraction is relatively simple."

"The main ingredient of ordinary edible salt is sodium chloride, sodium carbonate in soda ash, sodium bicarbonate in baking soda, sodium glutamate in monosodium glutamate, etc. Resources are simpler and can be obtained more easily.”

"Battery technology based on sodium element will no longer have all kinds of problems with lithium-based lithium iron phosphate batteries."

"Of course, if all are good, scientists will not give up sodium in the first place but use lithium as a battery raw material."

"Lithium has a lower atomic weight and a smaller ionic radius, making its theoretical mass specific capacity 3.3 times that of sodium, and its theoretical volume specific capacity is 1.8 times that of sodium, and the potential of lithium is higher, 12% higher than that of sodium. In terms of energy density, batteries made of lithium materials are also more dominant."

"Sodium-ion batteries have much higher requirements for the stability of the battery's positive and negative electrode materials than lithium-ion..."

In the middle of the stage, Feng Hao popularized information about sodium-ion batteries to many audiences.

In the live broadcast room, the audience listened with gusto, and even the barrage was much less!

It wasn't until the end that everything was explained clearly, and there was an enthusiastic response from the live broadcast room.

———————

"So that's it, wonderful, sodium-ion battery!"

"I don't understand it, but it seems to be very powerful!"

"Although I don't understand either!"

"All in all, it is a battery with a lower cost, and it is not limited by lithium resources."

"In terms of performance, will it be much lower than Hengxin Battery's previous lithium iron phosphate battery?"

———————

Looking at the projector screen, many viewers still didn't understand, Feng Hao sighed helplessly.

Fortunately, Kyushu Automobile already has specific products, and the performance is OK. The audience does not need to know how this battery comes from. It is their real concern whether it is easy to use or not!

After clapping his hands, Feng Hao smiled towards the camera.

"So what is the performance of Kyushu's sodium-ion battery? I believe everyone must be very curious. Let me take you to understand this question one by one!"

"First of all, in terms of battery performance, let me introduce to you this second-generation sodium-ion battery from Hengxin Battery Company."

"Yes, everyone heard it right, the second-generation sodium-ion battery!"

"In fact, as early as last year, Kyushu Motors had developed the first-generation sodium-ion battery technology."

"It's just that compared with lithium iron phosphate battery technology, the products produced by the first generation of sodium ion batteries are much worse than today's lithium iron phosphate batteries in terms of performance."

"Although it can barely be used, it can only be used a little bit, so Kyushu Motors did not mass-produce the first-generation sodium-ion battery technology, but continued to develop the second-generation sodium-ion battery technology."

"With more than a year of continuous research and development efforts, we finally broke through the difficulties of the second-generation sodium-ion battery technology a few days ago and successfully achieved mass production of the second-generation sodium-ion battery."

While Feng Hao was speaking, a staff member had already rolled out a large battery pack with a cart.

"Behind me is an experimental sample that was just produced today. Next, let me introduce you to this battery pack."

"The shape of this battery pack is believed to be recognized by many consumers."

"That's right, the battery packs that have been standardized by Dongfang Electric Power Company can be used in various new energy trams."

"It is the same as the previous lithium iron phosphate battery in terms of volume, and its weight is slightly heavier by 8.2 kg, but the amount of electricity that can be stored has not changed much, and it is also 70 kilowatt-hours."

"The performance in all aspects is basically the same as the previous lithium iron phosphate battery pack, but there are also better places, and the high and low temperature performance is stronger!"

"It can be used normally at a low temperature of minus 30 degrees. Even in the winter in northern my country, it can maintain the battery attenuation within 5%, which is even better than the previous lithium iron phosphate battery!"

"In terms of battery cycle performance, it is slightly less than 7,000 cycles of lithium iron phosphate batteries, and only 6,000 cycles of battery cycle performance."

—————————

The performance data of various aspects, compared with the previous lithium iron phosphate battery, made the audience in the live broadcast room more aware of the battery performance of this model.

"It's amazing my Kyushu Automobile Company, Hengxin Battery Company!"

"I thought this new battery would be much weaker than the previous battery in all aspects. I didn't expect it to have basically the same performance as the previous lithium iron phosphate battery!"

"Kyushu Motors is here prepared, is it already the second generation of sodium-ion battery technology?!"

"In other words, I feel that this new battery is more powerful. With the continuous advancement of technology research and development, it will definitely be better in the future!"

"Although the number of cycles is a thousand times lower, the production cost should be reduced a lot. Sodium can be seen everywhere, and there will be no problem of stuck raw materials. Overall, it is much better!"

"Electric vehicles can also be bought in Northeast China. Wow, it's not bad. I look forward to supporting our Kyushu Motors when the power station is built in the north!"

The live broadcast continued amidst the audience's discussion.

Feng Hao showed a bright smile: "After a brief introduction to the performance, the next point is the introduction of sodium-ion batteries today, the battery safety performance demonstration!"

"Kyushu Automobile, from the previous era of low-speed electric vehicles, we have been emphasizing one attribute, that is, safety, safety, and safety!"

"Compared with ordinary fuel vehicles, battery technology has many advantages, but it also has some disadvantages. If the quality of the battery is not up to standard, it is easy to cause a series of serious consequences."

"For example, the thermal runaway of the battery causes potential safety hazards. Traditional lithium batteries are loaded with huge energy inside. A little carelessness may cause the thermal runaway of the battery and cause a fire."

"And this kind of flame, often within a few seconds or ten seconds, quickly explodes, deflagrates, or even explodes, causing terrible consequences!"

"I don't know if everyone has paid attention to the burning incident of new energy trams caused by some inferior batteries."

When he said this, Feng Hao paused for a moment.

The screen in the live broadcast room switched, and a car with a mosaic brand appeared on the scene.

In the video, a high-speed electric vehicle collided with a truck.

Because of the violent collision, the new energy tram vehicle caught fire and burned for more than ten seconds, and the raging fire ignited the entire car.

Ten minutes later, the flames gradually extinguished, leaving only the wreckage of a car on the scene.

———————

"Hey, hey, do electric cars still spontaneously ignite? I didn't know such a thing!"

"This seems to be a small foreign electric car brand, and it has developed very rapidly in the past two years, but the car seems to have a quality problem, and this has happened several times."

"It's so shocking. The combustion is very full. It was burned directly into the frame of the car. The owner of the car is a little slower. After the accident, he didn't have time to escape from the car, so he could easily be cremated directly with one button!"

"Not to mention the power battery of the electric car, even the few lithium batteries that have been used before have caught fire and exploded!"

"Looking back and thinking about it now, several years have passed, and I have never heard of Kyushu Motors burning violently due to a battery problem, causing the vehicle to catch fire!

Whether it is Kyushu Automobile, Huaxia Automobile, or earlier low-speed electric vehicles, including a large number of two-wheeled electric vehicles, these vehicles using Hengxin batteries have never heard of fire accidents! "
