- Huawei has patent patents for a solid battery based on sulphide
- The company theorizes that it could unlock up to 3,000 km (1,864 miles)
- The ultra-fast load could exceed the battery in less than five minutes
Huawei is the last in an increasing list of car manufacturers and technological companies that explore the possible advantages of an EV adaptation with semiconductor batteries, with BMW, Mercedes-Benz, VW, Byd and Stellantis publicly tuting the technology.
Because News China reports that the technology giant has filed a patent that describes a semiconductor battery architecture with energy densities between 400 and 500 Wh / kg, which is two or three times that of the current EV battery landscape.
Currently, Huawei does not manufacture its own brand vehicles in China, but rather works with various car manufacturers to apply some of its existing technologies to vehicles.
According to the patent application, its batteries use a method that “boosts” sulfuric electrolytes with nitrogen to approach secondary reactions to the lithium interface. However, he keeps the rest of his technology near his chest, because the race for battery technology with mass semiconductor in complete and large-scale is well activated.
In addition, the company theorizes that it is able to rule out approximately 1,864 miles of variation in its battery technology, as well as to complete the load with 10 to 80% of the industry in less than five minutes.
However, some industry experts are skeptical about these daring claims, stressing that it is a jump of more than three times the current capacities of the most impressive electric vehicle range for sale today.
Addressing Electk, Yang Min-Ho, professor of energy engineering at Dankok University, said that such performances “could be possible in laboratory conditions”, but continued to explain that the reproduction of results in the real world, where loss of energy and thermal management play a key role, would be “extremely difficult”.
The teacher also quickly stressed that the nitrogen doping method is a “standard technique” which, once again, can be applied in a laboratory environment but is currently difficult to evolve to the point where it can be produced en masse to meet the demands of world car manufacturers.
Analysis: big titles, small steps
Naturally, China lifts into its dominance EV.
Megawatt’s load is one of the most recent subjects, but semiconductor batteries have also boiled under the surface for some time. Without a doubt, China will be the first of this technology, but it will probably not be as early as many national companies will do, nor as impressive.
In addition, the 1,800 mile figures seem largely useless, as it would require a huge battery that will add an excess weight and a blunt driving dynamics in a vain attempt to dissipate the concepts of range anxiety.
If Huawei could nail energy densities between 400 and 500 Wh / kg, it would be much better placed by producing smaller packs that can always offer an impressive range without needing huge and costly batteries.
When an EV can easily cover 600 miles on a single load, the range anxiety becomes largely obsolete, because there are so few drivers who want to sit for hours without a break. In addition, with the public loading network by widening and improving one year on the other, it is probably easier than ever to find a place to connect and stretch the legs.
