EV Canada Newsletter: Tesla's Advanced Battery Research Partnership with Halifax's Battery Pioneer Jeff Dahn release paper on 100 year battery.

Weekly Recap Issue #20 - Tuesday, May 31st, 2022

Hello, and welcome to the weekly EV Newsletter that keeps you up to date on the EV industry and, hopefully inspires you to be energy conscious while also saving time and money by avoiding the pumps all together.

What’s new from this week:

Canada

Jeff Dahn and Dalhousie University team release paper on 100 year battery life.

I have had the pleasure of meeting Jeff Dahn in person, as well as attending his presentations virtually. It’s really great to see EV battery development happening right here in Canada, let alone in Halifax - only 25 km’s from my home.

Since 2016, Tesla has established the “Tesla Advanced Battery Research” through a partnership with Jeff Dahn and the battery lab at Dalhousie University in Halifax, Nova Scotia. Recently Tesla has extended its contract with the team through 2026.

The partnership has produced many patents and papers on batteries for Tesla. Currently the focus for the team related to the potential increase in energy density and durability while also decreasing cost of batteries. They have recently released a new paper on a new nickel-based battery that could last 100 years while still maintaining the benefits of LFP cells when it comes to charging and energy density.

The paper details a nickel-based battery chemistry which maintains the longevity of LFP battery cells but has a higher energy density which increases range and decreases the number of batteries required to power electric vehicles.

The paper describes a nickel-based battery chemistry meant to compete with LFP battery cells on longevity while retaining the properties that people like in nickel-based batteries, like higher energy density, which enables longer range with fewer batteries for electric vehicles.

The group wrote in the paper’s abstract:

Single crystal Li[Ni0.5Mn0.3Co0.2]O2//graphite (NMC532) pouch cells with only sufficient graphite for operation to 3.80 V (rather than ≥4.2 V) were cycled with charging to either 3.65 V or 3.80 V to facilitate comparison with LiFePO4//graphite (LFP) pouch cells on the grounds of similar maximum charging potential and similar negative electrode utilization. The NMC532 cells, when constructed with only sufficient graphite to be charged to 3.80 V, have an energy density that exceeds that of the LFP cells and a cycle-life that greatly exceeds that of the LFP cells at 40 °C, 55 °C and 70 °C. Excellent lifetime at high temperature is demonstrated with electrolytes that contain lithium bis(fluorosulfonyl)imide (LiFSI) salt, well beyond those provided by conventional LiPF6 electrolytes.

The cells showed an impressive capacity retention over a many cycles.

The research group even noted that the new cell described in the paper could last a 100 years if the temperature is controlled at 25C:

Ultra-high precision coulometry and electrochemical impedance spectroscopy are used to complement cycling results and investigate the reasons for the improved performance of the NMC cells. NMC cells, particularly those balanced and charged to 3.8 V, show better coulombic efficiency, less capacity fade and higher energy density compared to LFP cells and are projected to yield lifetimes approaching a century at 25 °C.

The key to unlocking potential of these batteries is to use an electrolyte with LiFSI lithium salts, and as indicated in the paper, the benefits could also be applied to other nickel-based chemistries, including those with no or low cobalt.

The Genesis GV60 has hit showroom floors across Canada.

The Genesis GV60 is available for purchase in Canada. The base model called “Advanced” has a price of $71,000 CAD and the “Performance” trim level is available for $79,000 CAD.

The GV60 is the first electric vehicle for Genesis - Hyundai-owned luxury brand.All-wheel drive comes standard on both available models but neither of them are available for rebates in Canada.

“We are thrilled to begin our momentous journey towards full electrification with the launch of the GV60,” says Lawrence Hamilton, executive director of Genesis Motors Canada in a press release.

“We are excited that our Canadian guests will be able to experience the innovative technologies, bold design, and extensive suite of Genesis Connected Services offered in this distinctive vehicle.”

The GV60 Advanced trim is powered by a 74kW electric motor in the front and a 160kW motor in the rear for an approximate range of 399 kilometres. The Performance model offers two 160kW motors and an approximate range of 387 kms.

The vehicle is built on Hyundai’s Electric-Global Modular Platform (E-GMP), which is the same platform being used for the Hyundai Ioniq 5 and the Kia EV6. The GV60 can charge at 400V or 800V, depending on the charging system used and has vehicle-to-load charging capability.

According to Genesis, when charging at 350kW with the ultra-speed charging function, the battery can be charged from 10% to 80% in just 18 minutes.

The GV60 is one of the first EVs to have been built to accommodate wireless charging for when that infrastructure is available - however Genesis has not announced when it expects this technology to be available.

The “Crystal Sphere”, which is used as a shifter to operate the vehicle is one of the most distinctive features of the GV60.

The Crystal Sphere is located in the centre console and is an illuminated orb when the vehicle is turned off. When the GV60 is turned on, the sphere rolls 180 degrees upside down to reveal the shifter buttons that then allow the driver to put the car in motion.

EV Around the World 🌏

Details emerge on the DeLorean Alpha5.

The DeLorean is making a comeback in the form of an all-electric 4-seater with astonishing good looks and impressive performance. The DeLorean Alpha5 is the first of an all-electric lineup from DeLorean. The lineup is set to include an electric sedan, hydrogen SUV and a V8 coupe. The battery-powered coupe will be built in a limited run of 88 units and production will begin with a special Launch Edition model.

Although it may retain details like the gullwing doors, the Alpha5 has left the DMC-12 far behind in the past with it’s stunning looks.

Its massive gullwing doors are arguably the main highlight of the Alpha5 which are monstrous to allow for passengers to access the rear seats. The exterior looks amazingly sleek showing off an ability to capture performance and luxury.

The cabin is minimalistic which features, a display behind the steering wheel, and a central touchscreen that is physically integrates the dashboard with the raised center armrest.

As reported by InsideEV, the Alpha5 "base performance model"—this suggests more potent models are in the pipeline—packs a 100+kWh battery powering "multiple electric motors." This setup enables a sprint from 0-60 mph in 2.99 seconds, 0 to 88 mph (a reference to the speed the DMC-12 needed to time-travel in the Back To The Future movie trilogy) in 4.35 seconds, and a top speed of 155 mph (250 km/h). The range is estimated at 300 miles (483 kilometers).

The DeLorean Alpha5 will make its official public debut at the Pebble Beach Concours d'Elegance on August 18 before entering production in 2024 at an undisclosed location in Italy. Seeing as the vehicle is styled by Italdesign, which also penned the original DMC-12, the Italian design house may also manufacture it at the Italdesign Automobili Speciali production facility for low-volume vehicles. At this moment that is pure speculation, though.

NIO set to build US factory.

The electric vehicle offerings from Chinese EV automakers such as NIO and XPENG offer great vehicle range, features and looks. Some of the best looking EVs in my opinion come from NIO and XPENG. Check out the NIO ET7 or the XPENG P7.

In addition to those cars, they also offer SUVs! Which is a major obstacle to EV adoption - not having an affordable electric SUV. I really hope that these Chinese automakers are going to be able to enter the North American market to create more competition and reduce prices on EVs so that they can be more readily available at affordable prices.
