- Huawei has requested patents for a solid state battery based on sulphide
- The company theorizes that could unlock up to 3,000 km (1,864 miles)
- Ultra fast load could exceed the battery in less than five minutes
Huawei is the last in a growing list of car manufacturers and technology companies that are exploring the possible benefits of equipping an EV with solid state batteries, with people such as BMW, Mercedes-Benz, VW, Byd and Stellantis that publicly promote technology.
CAR News China reports that the technological giant has presented a patent that describes a solid state battery architecture with energy densities between 400 and 500 Wh/kg, which is two or three times greater than the current EV battery panorama.
Currently, Huawei does not manufacture its own brand vehicles in China, but works with several car manufacturers to apply some of its existing technologies to vehicles.
According to the application of patents, their batteries use a method that sulphide electrolytes with nitrogen to address lateral reactions in the lithium interface. However, it maintains the rest of its technology near its chest, since the race to produce mass state battery technology safely is already fine and really on.
In addition, the company theorizes that it is capable of obtaining about 1,864 miles of its battery technology, as well as completing the standard charge of the industry of 10-80% in less than five minutes.
However, some experts in the industry are skeptical of these bold statements, pointing out that it is a jump of more than three times the current skills of the most impressive electric vehicles today.
In statements to Electrek, Yang Min-Ho, professor of energy engineering at Dankook University, said such performance “could be possible in laboratory conditions”, but continued explaining that the reproduction of the results in the real world, where the loss of energy and thermal management play a key role, would be “extremely difficult.”
The teacher also hastened to point out that the nitrogen doping method is a “standard technique” that can again be applied in a laboratory environment, but is currently difficult to climb to the point that it can be produced in mass to meet the demands of global car manufacturers.
ANALYSIS: Large headlines, small steps
Understandably, China is enjoying its EV domain at this time and is not afraid to advertise innovations that have the potential to change the game.
The megawatt load is one of the most recent issues, but solid state batteries have also been bubbly under the surface for some time. Without a doubt, China will be the first in this technology, but it is likely not as soon as many national companies bathe, or so impressive.
In addition, the figures of 1,800 miles seem to a large extent useless, since it would require a large battery that will add an excess weight and a blunt driving dynamics in a vain attempt to dissipate the notions of range anxiety.
If Huawei can nail energy densities between 400 and 500 Wh/kg, it would be much better located producing smaller packages that can still offer an impressive range without the need for huge and faces.
When an EV can easily cover 600 miles with a single load, the range anxiety becomes obsolete to a large extent, since there are so few drivers who want to sit down for hours without rest. In addition, with the public load network expanding and improving year after year, it is now possibly easier than ever finding a place to connect and stretch your legs.
