Will the ear of lithium batteries end? Semi solid state batteries may become a new favorite in the industry

With the advent of the new energy vehicle era, many car companies are putting effort into batteries in order to create the most cost-effective cars. Among them, semi-solid state batteries or solid-state batteries belong to the top cutting-edge technology products.

As the name suggests, the electrolyte of solid-state batteries is made of solid materials. It relies on the migration of lithium ions between the positive and negative electrodes, so no electrolyte is needed to achieve the effect of electrification.

Compared to ordinary lithium-ion batteries, solid-state batteries have many advantages. Firstly, it will not produce a large amount of lithium dendrites like liquid lithium-ion batteries.

Many people may not know that most liquid lithium-ion batteries produce substances such as lithium dendrites. When lithium dendrites in the electrolyte grow to a certain extent, they will directly puncture the positive and negative electrode separators. In this case, the lithium battery will experience a short circuit problem. A slight mistake can cause electric vehicles to ignite or explode.

But solid-state batteries are different. Due to the fact that the electrolyte of solid-state batteries is solid particles, it cannot produce spikes like lithium dendrites, thus avoiding the occurrence of car spontaneous combustion.

But even if the positive and negative separators in solid-state batteries break, it's actually not a big deal. Because there is no liquid flow in solid-state batteries, their positive and negative electrodes will not short-circuit. That is to say, there is no possibility of explosion at all.

Engineers have conducted numerous needle tests using solid-state batteries and found that they do not explode. It can be seen that the safety of solid-state batteries can be guaranteed.

The most crucial thing is that due to the high mechanical strength of these solid electrolytes, they can withstand severe collisions and compressions. Even if there is a collision, the battery will be fine and the starter motor can still run back and forth.

In addition to having strong resistance to attacks, solid-state batteries also have a particularly wide temperature adaptation range. If it is a regular lithium-ion battery, it will catch fire above 80 degrees. But if replaced with solid-state batteries, they can withstand high temperatures of 150-200 degrees.

Scientists have envisioned that if solid-state batteries are mass-produced, they may be applied to oil exploration, underground drilling, and aerospace.

It can be seen that in various fields in the future, solid-state batteries are likely to replace lithium-ion batteries and become the new king of the battery industry.

Of course, aside from the ability to resist attacks and withstand high temperatures. The energy density of solid-state batteries is also a major highlight of them.

As mentioned earlier, the electrolyte of solid-state batteries has strong heat resistance. In this case, solid-state batteries can save a lot of cooling materials, thereby reducing unnecessary volume and mass.

Solid state batteries have extremely high energy density, reaching approximately 400-500Wh/kg, which is 2-3 times that of lithium-ion batteries.

It seems that once solid-state batteries are truly launched, a large piece of the lithium-ion battery market will be cut off.

Today's semi-solid state battery vehicles are still difficult to mass produce, and the yield rate of the products is extremely low. So if we want to wait for this type of car to be launched, it is estimated that it will take three to five years.

In fact, many car companies have also developed this type of new battery powered car a long time ago. At that time, all solid state batteries were tested. From the test results, it can be seen that the new car equipped with all solid state batteries can charge for 10 minutes and directly run 1200 kilometers, with a relatively good effect.
