Could ‘wandering meatloaf’ sea snail’s teeth be used to improve lithium-ion battery range?

Yes, it is as weird as it sounds.

One Bourns College of Engineering assistant professor, David Kisailus, has discovered the teeth of the gumboot chiton sea snail could be a model for nanocrystals that could be used in lithium-ion batteries and solar cells.

The gumboot chiton has been nicknamed the “wandering meatloaf” for its size and burnt orange coloration. The big but tasty-sounding snail, found off the Pacific coast from California to Alaska, subsists on algae harvested from rocks. It uses 70 to 80 rows of teeth to first grind away rock, then to consume the hidden algae.

What is so useful about algae-eating snail teeth? It’s the fact that the wandering meatloaf is able to synthesize magnetite for its outer tooth layer. Magnetite is not only magnetic; it’s also the “hardest biomineral known on Earth,” according to a Wards Auto report.

Astonishingly, the magnetite is created “at room temperature and under environmentally benign conditions,” Kisailus said in a statement.

If correctly utilized, the wandering meatloaf process of producing nanocrystals could yield more powerful solar cells and faster charging lithium-ion batteries, all at lower production costs.

While this sort of discovery is a bit beyond our day-to-day expertise, we love the concept. We’ve been hoping for a breakthrough that could help take EV batteries and solar power generation to the next level. We just hadn’t expected it to come from a wandering meatloaf sea snail.

Xiaomi has officially launched its SkyNomad SUV lineup in China. Xiaomi first revealed the N90 Max’s transforming cabin and rooftop bedroom back in July. The company has now put a price on the dedicated N90 Max Explorer Edition, which costs 299,900 yuan, or approximately $44,100. The regular seven-seat N90 Max starts at 269,900 yuan, around $39,700, making it 30,000 yuan cheaper than its earlier preorder price.

Audi just built its most efficient electric car ever. However, if you’re in the US, you'll likely only ever see it in photos. 

The company’s pitch is simple and quite intriguing. Its A2 e-tron doesn’t sport the largest battery on an Audi, but focuses on squeezing the most range out of it through smart engineering.

I have a soft spot for tiny cars, and China has a bunch of them. Geely’s latest Panda Mini takes that form and puts an electric engine into it. The updated Panda Mini Karting Edition launched in China earlier today with a CATL battery, four seats, and a rear wing that makes it look pretty sporty for its size.

Its limited-time subsidized price is 43,900 yuan, or around $6,540, compared with a regular listed price of 49,900 yuan, or approximately $7,435. The promotional offer runs through September 30, with additional purchase incentives subject to eligibility. Budget EVs come in many different shapes, but this one has enough personality to make you look twice.
