Description:
Huawei has filed patents for new solid-state battery technology that could underpin future EVs with enormous range and ultra-fast charging capabilities.

FULL STORY ======================================================================Huawei has filed for patents for a sulfide-based, all-solid-state battery The
company theorizes it could unlock up to 3,000km (1,864 miles) of range Ultra-fast charging could top the battery up in under five minutes

Huawei is the latest in a growing list of automakers and tech companies that are exploring the possible benefits of fitting an EV with solid-state batteries, with the likes of BMW, Mercedes-Benz, VW, BYD and Stellantis all publicly touting the tech.

Car News China reports that the tech giant has filed a patent that outlines
a solid-state 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 doesn't manufacture its own branded vehicles in China, but instead works with various automakers to apply some of its existing technologies to vehicles.

According to the patent application, its batteries use a method that dopes sulfide electrolytes with nitrogen to address side reactions at the lithium interface. However, it is keeping the remainder of its technology close to
its chest, as the race to mass-produce solid-state battery technology safely and at scale is well and truly on.

Whats more, the company theorizes that it is able to eke some 1,864 miles of range from its battery technology, as well as complete the industry standard 10-80% charge in less than five minutes.

However, some industry experts are skeptical of those bold claims, pointing out that it is a leap of more than three times the current range abilities of the most impressive electric vehicles on sale today.

Speaking to Electrek , Yang Min-ho, professor of energy engineering at
Dankook University, said that such performance "might be possible in lab conditions" but went on to explain that reproducing the results in the real world, where energy loss and thermal management play a key role, would be "extremely difficult".

The professor was also quick to point out that the nitrogen doping method is
a "standard technique" that, again, can be applied in a laboratory
environment but is currently difficult to scale to a point where it can be mass produced to meet the demands of global automakers. Analysis: big headlines, small steps (Image credit: Porsche)

Understandably, China is basking in its EV dominance at the moment and it
isnt afraid to publicize innovations that have the potential to change the game.

MegaWatt charging is one of the more recent topics, but solid-state
batteries have also been bubbling sway under the surface for some time. Undoubtedly, China will be the first to this technology, but it likely wont
be as soon as many domestic companies make out, nor as impressive.

Whats more, the 1,800-mile figures seem largely pointless, as it would
require a huge battery pack that is going to add excess weight and blunt driving dynamics in a vain attempt to dispel notions of range anxiety.

Should Huawei be able to nail energy densities between 400 and 500 Wh/kg, it would be far better placed producing smaller packs that can still offer an impressive range without the need for enormous, expensive batteries.

When an EV can easily cover 600 miles on a single charge, range anxiety largely becomes obsolete, as there are so few drivers that want to sit for hours on end without a break. Plus, with the public charging network
expanding and improving year-on-year, it is now arguably easier than ever to find a spot to plug in and stretch the legs.
