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.”

777 hp electric overland concept from Italdesign bows in Beijing [video]

The all-new, all-electric Italdesign Quintessenza concept is a high-tech Italian take on the Porsche Dakar concept that’s just begging to be put into production.

Making its debut at the Beijing Auto Show, the Italdesign Quintessenza concept embodies both the dynamic prowess of a GT and the versatile adaptability of a pick-up truck. At least, that’s what its makers say. And, if your idea of a pickup truck leans more towards “Subaru Brat” than “Ford F-150 Lightning,” that’s probably right!

The rear section of the Quintessenza converts from a “hatchback” to an open “pickup” bed in true Brat fashion. The rear seats are designed to flip 180-degrees backwards, providing a rear-facing, panoramic “stargazing” mode that promises, “(the) experience and feeling of connection with nature and the outside world.”

Stargazing mode

In its more conventional GT “mode,” the Quintessenza is arguably the best-looking Italdesign concept to come out in years, with vertical lighting elements up front and aggressively-sculpted rear haunches that this writer thinks would be a natural for Audi.

Those design elements aren’t just aesthetic – they’re loaded with electronics. “Two aerodynamic fins that integrate the ADAS systems are present on the upper back of the roof, at the level of the C-pillars,” reads the official release. “They map the surrounding environment when the satellite signal is poor, and offer multifunction lights indicating the car’s driving mode and braking when the hard top is removed.”

Quintessenza vertical elements

So, what kind of vehicle is the Italdesign Quintessenza? Is it a true overland GT, in the style of the Porsche Dakar or 911 SC/RS (the rally car that became the 959)? Is it a high-end spin on the classic Subaru Brat? A futuristic Ute for traversing the Australian outback? Or is it something else entirely?

That’s above our pay grades – but you, dear readers? You guys know what’s up, so check out the official Quintessenza launch video (below), then let us know what you think of Italdesign’s latest in the comments section at the bottom of the page.

The new Momentum Cito E+ dares you to leave the car at home [Video]

All the cool suburbanites are already taking their kids to school, loading up at the farmers’ market, and making deliveries on clever and capable cargo e-bikes, but the new Momentum Cito E+ from Giant raises the cargo bike bar even higher — and makes leaving the car at home easier than ever.

Momentum is a new brand of “lifestyle” e-bikes from Giant Group designed to deliver premium features to customers while still hitting that $3,000-4,000 market “sweet spot.” Their latest bike, the all-new for 2024 Cito E+ utility bike, does just that, coming to market with a premium battery, Bluetooth technology, a suite of high-end safety features, and a $3,200 starting price.

Premium battery

Getting the most out of your e-bike often means getting the most out of your battery — and Momentum absolutely gets that. The Cito E+ ships with a 780 Watt-hour Panasonic battery pack with 22700 cells that have been optimized for e-bike use.

Compared to other ebike batteries with similar power ratings, the Momentum’s Panasonic battery promises to be lighter and more durable, with superior IPX7 weather protection, thermal regulation, and other safety features built-in (in fact, Panasonic was the first e-bike supplier to score a UL safety rating for its batteries).

The battery is easily removable for charging at home or in an office, but it can be charged while it’s in the bike, too. Either way, charging won’t take long — from 0 to 80% of charge (approx. 60 miles) of range is available in 3.5 hours, while a full (75 mile) charge takes less than 5 hours.

Connected cargo bike

As our test rider highlights in the video (above), the Momentum Cito E+ uses a proprietary battery management system, or BMS, to monitor the battery pack for maximum efficiency and reliability down to the individual cell level.

The BMS uses Bluetooth connectivity to transfer battery health data, state of charge, and other important information straight to the RideControl app, which enables the bike’s owner to get an in-depth look at the overall state of their e-bike and provides valuable diagnostic data to both the technicians tasked with servicing the bike and Giant themselves, to help develop even better e-bikes in the future.

That connection to Giant Group is a huge potential benefit to Momentum Cito E+ buyers, by the way, as it gives them access to support from more than 1,200 brick and mortar Giant dealers across the US alone (above).

That’s a serious advantage that online-only bike brands simply can’t match.

Safety first … and maybe second, too

Momentum’s commitment to safety doesn’t stop at the battery. The Cito E+ features confidence-inspiring 4 piston hydraulic disc brakes and a heavy duty suspension for predictable handling even under heavy loads — important if you have to suddenly haul the bike down from its electronically assisted 28 mph top speed with precious kids and cargo on the back.

LED head and taillights with a lever-activated taillight ensure Cito E+ riders will be seen, too, helping you stay safer after hours.

Accessories and add-ons

‘This is a unique time’: ARK Invest’s chief futurist tackles tech innovation from AI to robotics

Private lives – why hot tech is shying away from IPOs

ARK Invest’s chief futurist lists five groups that should give tech investors an edge.

According to Brett Winton, robotics, artificial intelligence, multi-omics sequencing, public blockchain and energy storage are key areas because they’re all entering the marketplace at the same time.

“We believe that this is a unique time in technological economic history,” he told CNBC’s “ETF Edge” this week.

Winton collaborates with ARK Invest CEO Cathie Wood to maintain the ARK Venture Fund (ARKVX), which allows investors to buy into the private technology space.

According to the firm’s website, the goal of the fund is to make venture capital offerings of innovative spaces in the market accessible to individual investors. As of April 10, it shows the fund’s top holdings include Epic Games, known for online video game Fortnite, and biotech companies Freenome and Relation Therapeutics.

“Our emphasis is that we are investing in innovation over the long term and going to support management teams,” said Winton.

He contends it’s a strategy that’s often not prioritized.

“That’s a real challenge a lot of public market investors don’t have that long-term view,” Winton added.

The ARK Venture Fund is down more than 7% so far this year. However, it’s up almost 39% percent over the past 52-weeks.
