Electric Car Batteries that can be recharged in about 5 minutes

Electric car batteries with five-minute charging times produced
Exclusive: first factory production means recharging could soon be as fast as filling up petrol or diesel vehicles
Batteries capable of fully charging in five minutes have been produced in a factory for the first time, marking a significant step towards electric cars becoming as fast to charge as filling up petrol or diesel vehicles.
Electric vehicles are a vital part of action to tackle the climate crisis but running out of charge during a journey is a worry for drivers. The new lithium-ion batteries were developed by the Israeli company StoreDot and manufactured by Eve Energy in China on standard production lines.
StoreDot has already demonstrated its “extreme fast-charging” battery in phones, drones and scooters and the 1,000 batteries it has now produced are to showcase its technology to carmakers and other companies. Daimler, BP, Samsung and TDK have all invested in StoreDot, which has raised $130m to date and was named a Bloomberg New Energy Finance Pioneer in 2020.
The batteries can be fully charged in five minutes but this would require much higher-powered chargers than used today. Using available charging infrastructure, StoreDot is aiming to deliver 100 miles of charge to a car battery in five minutes in 2025.
“The number one barrier to the adoption of electric vehicles is no longer cost, it is range anxiety,” said Doron Myersdorf, CEO of StoreDot. “You’re either afraid that you’re going to get stuck on the highway or you’re going to need to sit in a charging station for two hours. But if the experience of the driver is exactly like fuelling [a petrol car], this whole anxiety goes away.”
“A five-minute charging lithium-ion battery was considered to be impossible,” he said. “But we are not releasing a lab prototype, we are releasing engineering samples from a mass production line. This demonstrates it is feasible and it’s commercially ready.”
Existing Li-ion batteries use graphite as one electrode, into which the lithium ions are pushed to store charge. But when these are rapidly charged, the ions get congested and can turn into metal and short circuit the battery.
The StoreDot battery replaces graphite with semiconductor nanoparticles into which ions can pass more quickly and easily. These nanoparticles are currently based on germanium, which is water soluble and easier to handle in manufacturing. But StoreDot’s plan is to use silicon, which is much cheaper, and it expects these prototypes later this year. Myersdorf said the cost would be the same as existing Li-ion batteries.
“The bottleneck to extra-fast charging is no longer the battery,” he said. Now the charging stations and grids that supply them need to be upgraded, he said, which is why they are working with BP. “BP has 18,200 forecourts and they understand that, 10 years from now, all these stations will be obsolete, if they don’t repurpose them for charging – batteries are the new oil.”
Dozens of companies around the world are developing fast-charging batteries, with Tesla, Enevate and Sila Nanotechnologies all working on silicon electrodes. Others are looking at different compounds, such as Echion which uses niobium oxide nanoparticles.
“I think such fast-charging batteries will be available to the mass market in three years,” said Prof Chao-Yang Wang, at the Battery and Energy Storage Technology Center at Pennsylvania State University in the US. “They will not be more expensive; in fact, they allow automakers to downsize the onboard battery while still eliminating range anxiety, thereby dramatically cutting down the vehicle battery cost.”.

nuclear power plants are being phased out ,,,,
surely the answer has to be clean burn fossil fuels ,,,
The mini-windmills pop-up when the transmission is in park.
As technology advances, so the efficiency of wind/solar generators will advance, together with better and efficient means to store the energy produced.
It's been thought that battery technology was the bottleneck slowing the widespread use of electric vehicles & alternate energy sources.
I presume the battery referred to in the OP is something like this ...
The cars sound Really Cool ...
m - excellent video. Thanks for sharing it.
f - Your previous comment was deleted, because it did not add anything positive to the blog.
It was only a personal attack. Comments should be about the blog topic, not about CS members.
I do not permit personal attacks focused against ANY of the commenters. I much prefer intellectual discussions. Childlike trolling is not permitted on my blogs.
r - While I fully understand where you re coming from, is it the sound itself, that is so great, or the power we have come to associate with that sound ?
If it is the sound itself, why don't we frequently listen to recordings of that sound.
I would surmise, that the sound itself is only an unnecessary byproduct of what has previously been required
to achieve the power desired.
As I said, I understand.
