Chapter 392 Blade Battery

"Isn't this a dimensionality reduction attack?"

"Let me go, sodium-ion batteries can't beat lithium-ion batteries, can they also beat lead-acid batteries?"

"I understand, I understand. Instead of fighting head-on with lithium-ion batteries, it is better to reduce the focus on lead-acid batteries to seize a larger market share."

"The boss is the boss."

"Alas!~"

"Are you going to study technology from scratch again?"

"..."

Facing scientific researchers, Luo Hui was very patient.

When communicating, always keep a smile on your face and kind eyes, just like a landlord facing the tireless mules and horses in his livestock pen.

The sodium-ion batteries developed by Sun Zhiyong are mainly 18650 columnar batteries, not the square batteries or blade batteries he expected.

There's just one little complication - a lot of useful space is wasted when packaging larger structures.

Sun Zhiyong hurriedly packed up the scattered documents while explaining in a roundabout way the reasons for the messy office.

What a great beast!
He is a rare good employee who devotes himself to research and production.

This is kind of fucked up.

The extra solder joints will waste a lot of manual processes and materials, and cost money.

Same battery pack.

This is a bit fatal.

Two fatal flaws will definitely dissuade many users.

"Mr. Luo, please take a seat."

This problem must be corrected!
"Oh, Mr. Luo, if you have any advice, I'm all ears."

It’s expensive and bulky.

"The assistant is on leave for the past two days. I will make you a cup of tea first, and then I will slowly report on the current situation of the research center."

He was actually a little disappointed.

The extra weight will waste more packaging materials and cost money.

The extra volume creates more dead space, which costs money and does not take up an energy advantage.

If cylindrical batteries are connected in series, the volume of the battery pack that can store 30 kilowatt-hours of electricity will be about one-third larger than that of blade or square batteries.

After answering the researcher's doubts, he said a few simple words of courtesy before leaving the laboratory and coming to the office accompanied by Sun Zhiyong.

It’s not that cylindrical batteries are bad. This structure is suitable for production and long-term storage. It is a classic battery packaging structure and has a wide range of applications.

Luo Hui casually pulled a chair and sat down unceremoniously. He raised his hand to stop Sun Zhiyong from making tea: "Let's talk about something serious. We just had some things that were hard to talk about in front of so many of your subordinates. Now we just want to talk alone."

"Professor Sun, don't bother."

Sun Zhiyong didn't know why, so he also pulled up a chair and sat next to the boss, pretending to be calm and listening to the instructions.

"Can our battery packaging design be modified, not into a columnar shape, but into other shapes?"

Do you understand batteries?
Upon hearing the boss's request, Sun Zhiyong almost jumped up and pointed at his nose and cursed.

His expression also became strange.

Fortunately, I still knew that I was holding someone else's job, so I could only pretend to be interested and continue to inquire: "What does Mr. Luo mean?"

"Can it be packaged into a square shape or a long strip?"

"Mr. Luo, cylindrical batteries are the most space-efficient shape. Whether they are alkaline batteries or lithium-ion batteries, they are basically packaged in this way."

"Professor Sun, have you ever thought about a problem - when cylindrical batteries are connected in series or parallel to make a battery pack, a lot of material and space will be wasted?"

"Uh...there is a problem."

"If the existing production process remains unchanged, the width will still be 65 millimeters. We just change the packaging process. Instead of rolling the battery body composed of positive electrode material, electrolyte and negative electrode material into a columnar shape, we will directly stretch it and roll it into a width of 60 millimeters. Five millimeters, a one-meter-two long strip?"

And this kind of operation?

Sun Zhiyong was stunned and looked at his boss in disbelief, but could not say a word. at the same time.

In my mind, I continued to calculate the approximate shape of the battery made according to the packaging process required by the boss.

It seems...it seems really possible.

6.5 cm wide, 120 cm long, 2 cm thick...it seems to be easy to connect in series.

Compared with cylindrical batteries, the battery pack has a great advantage in terms of volume and can reduce most of the welding points.

Lower cost.

Battery packs have higher energy density.

It can also reduce a lot of packaging material loss.

The cost can still be lower.

"Mr. Luo Yingming, this packaging structure does have advantages."

This is the end.

Sun Zhiyong no longer dared to look down upon the young people in front of him, thinking that he could completely control his boss in the field of battery technology.

"Is there any difficulty in the production process?"

Luo Hui ignored the flattery and directly cared about the packaging process.

It's obvious.

The columnar battery packaging process does not consider the structural strength of a single battery at all.

If you switch to a blade battery, structural strength is a big issue.

After all, the main components of sodium-ion batteries, such as cathode materials, electrolytes, and anode materials, are all in sol form and cannot support a huge structure with their own strength.

Even children can bend.

It must be equipped with higher-strength metal plates to ensure structural strength, anti-collision and anti-deformation.

"It's not difficult, it's not difficult!"

Sun Zhiyong grinned happily and waved his hands: "This is a question of the way of thinking. We have seen too many cylindrical batteries in the past. The thinking of us sodium-ion battery researchers is trapped in the cylindrical battery structure, forgetting that there are more packages. Way."

"If used in energy storage equipment, this long strip structure is more cost-effective and has higher energy density for the same volume."

"If it is used in battery vehicles... just shorten the length and make it a standard structure for lead-acid batteries, and it can be directly replaced."

"One word wakes up the dreamer."

"Mr. Luo!"

Just take it!

Seeing that Professor Sun no longer had the arrogance of being an expert in his eyes, Luo Hui nodded with satisfaction: "This packaging structure is called a blade battery."

"Okay, okay, it's called a blade battery. We will follow up immediately to modify the packaging process and strive to complete the relevant tests within a month."

"Professor Sun, leave these miscellaneous things to the researchers. You have to do something big."

"Mr. Luo, are you ready to start production?"

"First build a small factory with an annual production capacity of 10 gigawatts to see if this blade battery is feasible."

"No problem, I'll choose a location right away."

"Professor Sun, it's better to leave this trivial matter to other researchers. You have to do the big things."

"Mr. Luo, I don't understand. A battery factory with an annual production capacity of ten gigawatts is not a big deal. What is a big deal?"

"Of course it is to further reduce the production cost of sodium-ion batteries."

"Ok?"

"I have an idea to build a very large seawater desalination plant near the coastline in Hebei Province. It will use solar energy and waste heat to turn seawater into fresh water and sell it to steel companies and water conservancy departments as domestic and agricultural water."

"What a genius idea, Mr. Luo. Sell the fresh water, and the remaining sodium salt will become our raw material for battery production!"
