States the developers and maufacturers of the new Li-ion batteries.

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.

Thomas Chadwick (Feb 02 2021 3:11PM) : Solution Goal more

StoreDot gives a goal for the battery, aiming to deliver 100 miles of charge to a car battery in 5 minutes by 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.”

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.

Thomas Chadwick (Feb 02 2021 3:01PM) : Same Priced Solution more

The CEO of the battery company says that the cost of the improved solution batteries would be the same as the existing Li-ion batteries due using silicon instead of germanium.

“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.”

Janet Ilko (Feb 08 2021 10:47AM) : I have been wondering about this, our neighbors have a charging station in their home for their electric cars, but the batteries eventually will wear out and what will that do to the environment?

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.”

Yara Ahmed (Feb 05 2021 2:58PM) : If this becomes a feasible solution it could very easily assist in the fight against climate change

Research by Wang’s group is being developed by the company EC Power, which he founded. It carefully increases the temperature of the battery to 60C, which enables the lithium ions to move faster, but avoids the damage to the battery usually caused by heat. He said this allowed a full charge in 10 minutes.

Wang said new research published in Nature Energy on Monday showed this battery could be both affordable and eliminate range anxiety. “Finally we are achieving parity with gasoline vehicles in both cost and convenience. We have the technology for $25,000 electric cars that race like luxury sport cars, have 10-minute rechargeability and are safer than any currently on the market.”

Wang noted that fast charging must also be repeatable at least 500 times without degrading the battery to give it a reasonable life and that the EC power battery can do so 2,500 times. Myersdorf said the StoreDot battery could be recharged 1,000 cycles while retaining 80% of original capacity.

Thomas Chadwick (Feb 02 2021 3:19PM) : Statistics for Skeptics more

Some statistics that skeptics might have been wondering about. Declares that the battery would lose 20% of its capacity after 1000 cycles.

Anna Tomaszewska, at Imperial College London, UK, who reviewed the fast-charging batteries in 2019, was more cautious about the speed of their rollout. “I think technologies [like StoreDot’s] could start entering the market in the next five years or so. However, since they will be more difficult and expensive to manufacture, we’re likely to initially only see them in niche markets that are highly performance-driven and not as price-sensitive as electric vehicles,” she said.
