There is good news and bad news for electric vehicles at the moment. The bad news is that Toyota announced that the installation of solid-state batteries in small batches may be delayed until 2030. Toyota previously said that it has mastered 60% of the solid-state battery patents on the market, and it is expected to officially usher in mass production and installation in 2025, but it was suddenly postponed for five years. So whether solid-state batteries will work or not, no one knows now, which is actually a major blow to the field of electric vehicles.
For a long time, the recognized shortcomings of electric vehicles are slow charging speed and short range. There is also good news that CATL's battery has made another breakthrough!
CATL has developed ultra-rechargeable batteries, which have been mass-produced. On the Zhiji LS6 model, which was launched in October this year, CATL uses a new super battery pack, coupled with a 900V super fast charging platform, which can be charged in ten minutes and has a range of up to 350km, which is quite good. It is worth mentioning that this new battery can be continuously discharged without thermal runaway, so this Zhiji LS6 can achieve 3Break 100 in 48 seconds. On the one hand, the motor performance is very strong, and on the other hand, the battery characteristics are stable and controllable, which is a big breakthrough for electric vehicles, which also means that the shortcomings that limit electric vehicles are basically gone.
Seeing this, some friends may express concern that the current battery capacity pack is getting larger and larger, and once it is bumped or punctured, it will lead to a fire quickly. In fact, the spontaneous combustion of electric vehicles in the surrounding area has been declining rapidly, also because major car manufacturers have put the problem of battery pack fire in the first place.
CATL gives Super Shenxing Battery a new set of safety valves!CATL has set up a firewall for the battery, using a special material that can withstand 1000 degrees Celsius for 10 minutes, which effectively isolates the damage to the battery due to uncontrolled damage. When there is an abnormally high temperature inside the battery pack, the battery also has a precise spray to quickly cool down, and an exhaust hole is set to quickly discharge the high-temperature heat out of the battery.
It also brings the safety properties of the battery, and the upper, lower and side frames of the battery are dust-sealed and more robust to keep the battery pack structurally intact during a bump.
In addition, this intelligent battery also participates in the control of the electrification of the whole vehicle, which can heat the battery in winter, and through thermal management, the range in winter will not be excessively reduced. Compared with some traditional ternary lithium batteries or silicon batteries, this super battery has a 15% increase in winter range.
The efficiency of this new set of batteries for kinetic energy** has also been increased by 32%, and the kinetic energy** can be better stored in the battery during braking or downhill to achieve the purpose of energy saving.
With the successive appearance and installation of new technologies, there is less and less living space for fuel trucks in the future. According to the model, it is expected that the proportion of electric vehicles in China will exceed 50% by 2025. For fuel vehicles, this is indeed a heavy blow.
