As the competition in the electric car market intensifies, the progress of solid-state batteries is becoming more and more compelling:
For example, Volkswagen recently announced that it will significantly increase its cooperation with QuantumScape to promote the mass production of solid-state batteries.
The all-solid-state battery with a range of 960 kilometers and a life span of up to 20 years displayed by Samsung has also completed the delivery of the first batch of batteries;
At the same time, Mercedes-Benz has also partnered with Factorial Energy to announce that the new solid-state battery will soon enter mass production.
For new energy vehicle owners, this undoubtedly means that a new era is coming...
Against such a background, car owners can laugh!
Because after solid-state batteries replace lithium batteries, new energy vehicles can benefit from it in four aspects.
01 Longer range
Although many people have heard of this concept, the essence behind it is far more powerful than everyone thinks.
Why?
Because of the introduction of solid electrolytes, the traditional liquid electrolytes are replaced.
This not only reduces the internal space occupancy, but also greatly improves the conduction efficiency of lithium ions.
To put it bluntly, solid-state batteries are able to store more electrical energy in the same volume.
Take the current 700 km tram as an example, it can directly increase the range by 50% or more....
This is not nonsense, because let alone solid-state batteries, the "semi-solid batteries" that have been installed have shown this strength.
Take the Zhiji L6 Lightyear Edition as an example, it is equipped with a 133-degree semi-solid battery, which directly achieves a 4WD CLTC 1000 km range.
Considering this situation, the anxiety about the range of the tram or something naturally does not exist.
After all, at this level of battery life, what everyone has to worry about is not "whether the battery life is enough", but "whether the body is good"!
02 Greater security
Many people may have heard the rumors, but in fact, solid-state batteries are more powerful than rumors.
Because its electrolyte has changed from liquid to solid, this seems to be a "small step", but it directly solves many problems.
Why?
This is because the liquid electrolyte is susceptible to lithium dendrites growing when charged or over-discharged.
And this thing, when it grows to a certain stage, will gradually penetrate the battery separator, resulting in a short circuit.
As a result, thermal runaway occurs, and even spontaneous combustion or explosion occurs.
But solid-state batteries are different, and none of the lithium dendrites can grow due to physical stability...
Since there is no such thing, the "short-circuit risk" naturally does not exist.
In addition, solid-state batteries will also be more thermally stable.
To put it bluntly, the operating temperature range of traditional lithium batteries is generally between -20°C and 60°C, while the range of solid-state batteries can be from -73°C to 120°C.
In this context, it is natural that there is no need to worry about various accidents caused by batteries.
03 Longer service life
Although the current lithium battery, the service life has been very long.
For example, if you have been driving an electric taxi for 8 years, it has traveled 1.4 million kilometers and can still be used normally.
But semi-solid batteries, often stronger than that.
Because of traditional lithium batteries, the cycle life is generally about 1000-2000 times.
Solid-state batteries, on the other hand, are expected to have a cycle life of more than 4,000 cycles due to a more stable solid-state electrolyte.
This also means that the myth of "one car for three generations" will also happen to the new energy body.
In addition, in terms of "calendar life", solid-state batteries are also very powerful.
As we mentioned at the beginning, in July this year, Samsung's solid-state battery with a range of 960 kilometers has completed the first deliveries.
It is reported that this battery has a lifespan of up to 20 years and can be quickly charged to 80% in 9 minutes.
04 Faster charging
Although we have just mentioned, Samsung's solid-state battery can be quickly charged to 80% in 9 minutes.
But this is just the beginning, from the actual situation, solid-state batteries can be more powerful.
Why?
To put it simply, the "solid electrolyte" has a higher ionic conductivity.
For example, with sulfide as the main electrolyte, the lithium-ion conductivity reaches 32 mS/cm, which is three times that of the current liquid electrolyte (10 mS/cm).
In other words, the charging time of this solid-state battery will be 3 times or even more than that of a liquid battery.
The reason for saying more is that solid-state batteries have a higher upper operating voltage limit, which allows it to withstand higher charging power.
To put it bluntly, it is not that the liquid electrolyte cannot be faster, but that it is afraid that the heat will seriously cause "thermal runaway".
However, solid-state batteries are different, due to their thermal stability and superior physical structure, they can better handle high-power charging and reduce safety risks.
So, the ceiling will be even higher!
In general, owners who like new energy vehicles can laugh.
According to the current process, it may be another two years before we can get a car equipped with a solid-state battery.
When the time comes, where will you go in such a car? You can talk about your own enjoyment!
