In a significant advancement for EV technology, researchers at Chung-Ang University in South Korea have made a breakthrough in lithium-ion (Li-ion) battery charging times and safety.

Published in the journal Energy Storage Materials, their study focuses on improving Li-ion batteries for EVs.

The challenge with current Li-ion batteries lies in achieving rapid charging without compromising the battery’s energy density, which affects the vehicle’s range and charging times. Additionally, fast charging has raised safety concerns due to lithium plating, which can lead to high cell polarization.

The research team has developed a strategy to mitigate these issues by enhancing the electrolyte composition within the battery. By using concentrated LiPF6 (a Li-ion battery electrolyte) in combination with linear carbonates, the team aimed to improve the desolvation process, which is critical for rapid ion movement into the graphite anode. They specifically focused on electrolytes with low activation energy, such as dimethyl carbonate, to facilitate faster charging.

Their findings indicate that these electrolyte modifications can significantly enhance fast-charging capabilities while maintaining battery stability. Laboratory tests on a 1.2-Ah pouch cell demonstrated that the battery could retain three times more capacity over 200 cycles, and importantly, it prevented the cell swelling commonly associated with lithium plating.

Moreover, the study employed molecular dynamics simulations to understand the effects of different electrolyte concentrations on battery performance. This dual approach of practical experimentation and computational analysis provides valuable insights into how future batteries can be engineered for ultra-fast charging capabilities.

Lead researcher and associate professor Janghyuk Moon believes that these advancements could make EVs more practical by reducing charging times and extending vehicle range, thus encouraging broader adoption.

Moon said, “By improving the kinetics and stability of batteries under fast charging conditions, we hope to make a meaningful impact on the EV industry and ultimately on people’s daily lives.”

Italy is putting a big hybrid floating solar–floating wind farm in the sea

Italy is putting a big hybrid floating solar–floating wind farm in the sea

A 540-megawatt (MW) hybrid floating solar–floating wind farm is going to be developed off Italy’s southern coast, in the Ionian Sea.

Dutch-Norwegian offshore solar company SolarDuck, Italian investment fund Arrow Capital, and Italian developer New Developments are jointly developing the Corigliano project, which will be in the Gulf of Taranto off the Calabrian coast of Corigliano-Rossano:

SolarDuck is a spin-off of Damen Shipyards, a major shipbuilder in the Netherlands. It’s tapped into that knowledge to design elevated solar platforms made of offshore-grade aluminum that sit 10 feet (3 meters) off the water to withstand rough waters. The elevation also reduces salt deposits on the solar panels. (Floating solar farms on lakes and ponds tend to sit directly on the water.)

The triangular floating platforms are modular, so they can be connected to form large plants. Plus, the platforms have slip-resistant walkways and fences for access and maintenance.

The hybrid floating solar–floating wind farm will feature 420 MW of offshore wind and 120 MW of floating solar. It will have 28 floating wind turbines, but SolarDuck’s announcement doesn’t indicate who is developing them. We’ve reached out to SolarDuck for details and will update when we hear back.

The Corigliano hybrid floating project is expected to come online in 2028.

SolarDuck is running an up to three-year 5 MW pilot with multinational energy company RWE in the North Sea, 7.5 miles (12 km) from The Hague’s Dutch coast. In December, it secured €15 million in funding, and it’s going to install Japan’s first offshore floating wind farm.

Doroni unveils production-intent H1-X eVTOL, offering personal air travel up to 120 mph [Video]

Doroni unveils production-intent H1-X eVTOL, offering personal air travel up to 120 mph [Video]

Young urban air mobility (UAM) developer Doroni Aerospace is stepping out of the shadows and into the eVTOL startup with the official reveal of its flagship aircraft – the H1-X. The two-seat eVTOL was showcased during a livestream event today and is damn close to being market-ready, touting some impressive specs.

Doroni Aerospace was founded in 2016 by Doron Merdinger – a lifelong entrepreneur with 25 years of design, manufacturing, and firm management expertise.

To bring his dreams of sustainable aviation transportation to life, Merdinger assembled a team of engineers and technicians working together to democratize flight in a growing eVTOL segment.

The result of those efforts is the HX-1, Doroni’s flagship “flying car,” better known as an electric Vertical Takeoff and Landing (eVTOL) vehicle. After years of development behind the scenes, which we at Electrek have kept close tabs on, Doroni has finally revealed the H1-X to the public, which looks pretty cool. Have a look for yourself.

Doroni hard launches with production-intent eVTOL

The eVTOL startup shared many details of the H1-X earlier today during a livestream event you can view below. While Doroni’s flagship aircraft is an eVTOL through and through, its design and use vary from several of its competitors in development.

For instance, Doroni designed the H1-X as a two-seat personal aircraft rather than the larger cabins designed for air taxi services many other companies are working on. The H1-X also features a unique tandem wing configuration, with propellers built in (less risk of decapitation!)

The company says this design feature enhances the eVTOL’s lift and efficiency compared to traditional designs, and its wing fences can better manage airflow. The ducted fans are also quieter, even when the eVTOL’s eight electric motors are revving. Doroni’s CEO spoke during the eVTOL launch event:

The H1-X is not just a vehicle; it’s a leap toward a future where freedom of movement and sustainability coexist. Our dedication to innovation, safety, and the environment is embodied in every aspect of the H1-X, marking a new chapter in transportation.

Doroni shared that the H1-X weighs 1,850 pounds, can haul a payload capacity of 500 pounds, and can fly for 40 minutes on a single charge. What’s most interesting is that the incoming eVTOL can reach a top speed of 120 mph! Hopefully, Doroni will aid in training and certifying its future owners because that’s a lot of speed for the average person.

Representatives for Doroni Aerospace told Electrek that the first several examples of the H1-X eVTOLs are currently being built and will be used for extensive test flights at the end of the year. That being said, we were told the aircraft you see below is the go-to-market product, although there may be some minor tweaks before scaled production.

The H1-X has already received FAA certification for flightworthiness in the US and is expected to enter mass production in 2026. Each eVTOL is expected to cost between $300,000 and $400,000. You can learn more from the replay of the entire reveal event below:

Fisker is talking to Nissan for a lifeline and electric pickup partnership

Fisker is talking to Nissan for a lifeline and electric pickup partnership

Nissan has been revealed as the potential savior of Fisker. The Japanese automaker is reportedly talking with Fisker to invest in the company and partner on electric pickup trucks.

Earlier today, we reported on Fisker’s disastrous fourth-quarter results showing that the electric vehicle startup lost $400 million in 2023 and it now has less than $400 million of cash on hands.

The automaker had to admit that it wouldn’t be able to continue operations past next year without a big cash injection.

It did reveal that it was talking to a “large automaker” about an investment that could save the company.

Now, Reuters reported that the automaker in question is Nissan:

Nissan is in advanced talks to invest in electric vehicle maker Fisker (FSR.N), in a deal that could provide the Japanese automaker with access to an electric pickup truck while giving the struggling startup a financial lifeline, according to two people familiar with the negotiations.

The deal would reportedly involve Nissan investing $400 million in Fisker. It would also involve Nissan building the Alaska pickup truck unveiled by Fisker last year at one of its US plants.

On top of it, Nissan could use the Alaska platform to build its own electric pickup truck.

Neither Nissan nor Fisker commented on the report.

Fisker’s stock dropped by more than 50% today after the release of its earnings, but the stock recovered a bit after the report that Nissan is considering investing.

The stock currently trades at a valuation of $295 million.

Electrek’s Take

I’m not sure what to think about it. I’ve never been a big fan of Fisker, and I’ve warned people about investing in the company before.

If the report is true, I don’t know what Nissan sees in this. If they are behind on developing electric pickup trucks, it might be worth it for them, but I think that any significant investment would be a takeover the company.

It is now worth less than $300 million and that might be an attractive investment as a company that had $200 million in revenue last quarter in the growing EV market, but the looks are deceiving.

As I’ve highlighted before, Fisker was desperate in its previous fundraising efforts and took big convertible notes, which now add up to $1.2 billion, according to its last SEC filing.

Currently, there’s just no way Fisker can manage to pay that back and therefore, they will convert to stock and drastically dilute it for current shareholders.

So I don’t see a good outcome here other than Nissan picking the whole company up for cheap and accelerating its EV programs with it.
