423: Solid-state batteries

The experiments that Zhao Xu and the others are conducting.

In fact, they were basically all specifically designed by Guo Hao, representing some of Guo Hao's conjectures and ideas derived from mathematical modeling.

After all, Guo Hao had previously conducted battery experiments.

He had worked on lithium batteries with the CATL, so he could be considered deeply involved in battery experiments.

Later, Yan Yating, due to a mistake, created a type of carbon nanotube composite material, and after incorporating it into lithium batteries, it unexpectedly increased the energy density of the lithium batteries.

This incident also caught Guo Hao's attention at the time.

However, at that time, he not only didn't have his own Laboratory, but also his interest wasn't in batteries.

At that time, he was more interested in theoretical work; there were many things waiting for him to do.

Working on batteries was certainly not among his backup plans.

But now it's different.

First, there is the practical demand.

For electric energy to truly become the future, humanity will have a huge demand for high-energy-density batteries, whether for mobile phones or vehicles.

Or other devices, charging efficiency, energy density.

If these two can be breakthroughs, it can be said to be of extraordinary significance for human development and for the development of Dragon Country!

Then came the Big Leader's instructions.

The Big Leader wanted him to make some breakthroughs in this area.

Guo Hao naturally couldn't refuse.

That's why there are battery experiments.

According to the modeling, a total of several hundred sets of battery experiments were conducted, with the main purpose of replicating the battery additive that Yan Yating accidentally created before.

To replicate that process, Guo Hao added various different types of carbon nanotube materials to all of these hundreds of battery experiments.

All of these were synthesized based on the previous carbon nanotube material, using data calculated by Guo Hao with Computational Materials Science.

After all, batteries are too complex, involving many points.

And Guo Hao chose to first break through from the perspective of the carbon nanotube material additive.

Then try to solve the problem of dendrite growth.

Finally, try solid-state battery, and even lithium-air battery.

After all, it has been proven that carbon nanotube materials, as additives, can indeed cause some changes in lithium batteries, including increasing energy density and even slightly changing the battery morphology.

Of course, for most people, this is also a metaphysical problem.

It was the same when helping the CATL with research; thousands of sets of battery experiments were conducted, but the key to the combination was never found.

Although theoretically, lithium batteries should gain performance improvements after the introduction of carbon nanotube transistors, they conducted so many sets of experiments.

They didn't get any improvement at all.

It was only after Yan Yating's mistake, which resulted in the fusion of scrapped carbon nanotube material and lithium battery material.

Only then did they achieve a certain degree of success!

So, this stuff is very difficult!

And Guo Hao designed so many experiments, essentially to test whether his modeling was accurate!

And the success of this lithium iron phosphate battery proves that Guo Hao's mathematical model is accurate!

Based on the success of this lithium iron phosphate battery, Guo Hao began to continue refining the mathematical modeling.

There are too many points that lithium-air battery needs to solve, such as the risk of short circuit caused by dendrite growth, which needs to be suppressed by artificial SEI film or solid electrolyte.

Or the poor conductivity of Li₂O₂, which leads to severe polarization and requires a high-efficiency catalyst to reduce overpotential.

There is also the problem that the theoretical life of lithium-air battery is too short, making commercialization difficult, and a series of other issues.

But the success of this lithium iron phosphate battery, which increased the energy density by nearly double, gave Guo Hao another idea.

That is solid-state battery.

Currently in the Laboratory, the maturity of solid-state battery is far beyond that of lithium-air battery.

The cathode material uses lithium iron phosphate, the solid electrolyte uses oxides or sulfides, and the anode material can directly use lithium material.

Theoretically, the energy density of solid-state battery can completely exceed 500Wh/kg, and if carbon nanotube material is mixed into the solid electrolyte.

To accelerate the flow of current between the positive and negative electrodes and enhance the energy density of the battery.

Is it possible to make the battery energy density exceed 1000Wh/kg?

That way, although it is still not as good as the energy density of gasoline, it is already very good!

After browsing several papers related to solid-state battery.

Guo Hao began to try to design experiments and establish mathematical models.

The mathematical model for this type of battery is very complex, and it is also extremely troublesome to build.

It took three days.

After Guo Hao calculated a lot of data, a rough mathematical model was built.

After sending the experimental procedures to Zhao Xu.

Guo Hao finally breathed a slight sigh of relief.

Next is waiting. Doing experiments is inherently very troublesome, consuming energy and physical strength.

Only workhorses do experiments!

Fortunately, I am not a workhorse!

My Laboratory has enough workhorses!

After throwing the tedious things to the Laboratory workhorses, I can do something more relaxed!

And just as Guo Hao finished these things.

Xiao Xin sent him a reminder.

His Cloned Organs experiment seemed to be completed!

With a nervous heart, Guo Hao walked down to the underground Laboratory.

He came to an artificial uterus next to him.

This thing was also specially made by Guo Hao. It is an artificial uterus cultivated using biological materials, specifically designed to simulate the environment inside the human uterus.

He took a deep breath.

Guo Hao opened the artificial uterus.

In an environment full of nutrient solution, blood vessels were growing everywhere. A heart was beating in the center of the artificial uterus!

It succeeded!

Looking at the artificial heart in front of him, Guo Hao's eyes were filled with intense excitement.

Artificial organs, success was achieved!

Of course, there is one last step left.

Guo Hao asked Xiao Xin to extract some tissue from this heart for testing and compare it with Guo Hao's heart using internal imaging.

That's right!

It was almost completely identical to his own heart, both genetically and physically!

Amazing!

Guo Hao felt a little emotional.

Guo Hao completely summarized the experience of this Cloned Organs experiment from the previous experiments on enhancing animal genes.

This heart can be used for gene enhancement experiments.

The human experiments he needs can also continue!

This made Guo Hao slightly relieved.

However, before that, the paper on this technology should also be able to be organized. This kind of thing that benefits all mankind and does not harm the interests of Dragon Country.

Publishing a paper is also a good thing.

Thinking of this, Guo Hao closed the artificial uterus and returned to the villa.

It took some time for Guo Hao to organize the paper.

He originally thought of directly publishing it in Cell or Nature, after all, he had never published content related to Biology before.
