For the first time, batteries capable of charging a car battery completely in five minutes have been manufactured in a factory, a huge step toward charging a car battery (Electric cars) as quickly as gasoline or diesel vehicles.
While electric vehicles are critical in the fight against climate change, drivers are concerned about running out of energy during a journey. The new lithium-ion batteries were designed by Eve Energy, the Israeli company StoreDot and built on regular production lines in China.
StoreDot has already tested its “very fast-charging” battery in phones, drones, and scooters. The 1,000 batteries it has made thus far are intended to demonstrate its technology to automakers and other industries. Daimler, BP, Samsung, and TDK have invested in StoreDot, which has raised $130 million to date and is named a 2020 Bloomberg New Energy Finance Pioneer.
Charging a car battery can be done within five minutes. However, this requires far more powerful chargers than are currently utilized. By 2025, StoreDot hopes to charge a car battery 100 miles in five minutes using the existing charging a car battery infrastructure.
“The primary impediment to electric vehicle adoption is no longer cost; it is range anxiety,” stated Doron Myersdorf, CEO of StoreDot. “You’re either frightened of getting stranded on the highway or of having to spend two hours at a charging a car battery station. However, if the driver’s experience is identical to that of fueling [a petrol automobile], this real fear subsides.”
“A five-minute charging a car battery time for a lithium-ion battery was previously believed impossible,” he explained. “However, we are not disseminating a lab prototype; rather, we are disseminating engineering samples from a mass production line. This demonstrates that it is practical and ready for commercialization.”
Existing Li-ion batteries use only graphite as one electrode, pushing lithium ions into it to store charge. However, when these are rapidly charged, the ions become clogged and can convert to metal, shorting out the battery.
The StoreDot battery substitutes graphite with semiconductor nanoparticles, allowing for ions’ more rapid and easy passage. At the moment, these nanoparticles are made of germanium, which is water-soluble and easier to manufacture. However, StoreDot intends to employ silicon, which is significantly less expensive and anticipates releasing prototypes later this year. Myersdorf stated that the cost would be comparable to current Li-ion batteries.
“The battery is no longer the bottleneck for ultra-fast charging,” he explained. Now, he explained, charging a car battery station and the networks that feed them must be updated, so they are collaborating with BP. “BP has 18,200 forecourts, and they recognize that if they do not repurpose them for charging, they will become outdated in ten years – batteries are the new oil.”
Dozens of firms worldwide are working on charging a car battery fast, including Tesla, Enevate, and Sila Nanotechnologies. Others are investigating novel chemicals, such as Echion, which employs niobium oxide nanoparticles.
Elon Musk, Tesla’s CEO, tweeted on Monday: “Battery cell manufacturing is the key bottleneck impeding the transition to a sustainable energy future. Significant issue.”
“I believe that such fast-charging batteries will be available to the general public in three years,” said Prof Chao-Yang Wang of Pennsylvania State University’s Battery and Energy Storage Technology Center. “They will not be more expensive; in fact, they will enable automakers to reduce the onboard battery size while still removing range anxiety, resulting in a significant reduction in car battery costs.”
His company, EC Power, is developing the research conducted by Wang’s group. It gradually raises the battery’s temperature to 60C, allowing the lithium ions to flow faster while avoiding the damage caused by heat. He stated that the method enabled a complete charge in ten minutes.
Wang stated that recent research published in the journal Nature Energy indicated that this battery might be inexpensive and anxiety-free. “At long last, we are attaining cost and convenience parity with gasoline automobiles. We have the technology to build $25,000 electric cars that perform like premium sports cars, charge in ten minutes, and are safer than any now available.”
Wang also emphasized that fast charging must be repeatable at least 500 times without deteriorating the battery to provide a useful life, which the EC power battery can accomplish 2,500 times. According to Myersdorf, the StoreDot battery can be recharged 1,000 times while preserving 80% of its original capacity.
Anna Tomaszewska of Imperial College London in the United Kingdom, who reviewed fast-charging batteries in 2019, was more cautious about their rapid adoption. “I believe such technologies [such as StoreDot’s] will begin to enter the market within the next five years or so. However, because they will be more complex and expensive to develop, we are likely to see them first primarily in niche markets that are more performance-oriented and less price-sensitive than electric vehicles,” she explained.
A few weeks ago, the UK newspaper The Guardian published an article that must have been music to the ears of even the most apprehensive EV driver: a business has produced EV batteries that can be fully charged in less than five minutes.
As stated earlier, Israel-based StoreDot battery technology startup has developed a scalable manufacturing process for EV power packs, implying that mass-market “five-minute batteries” are not far away.
StoreDot’s batteries charge completely in five minutes, which has the potential to revolutionize EV charging. However, the conditions must be ideal.
Prof Chao-Yang Wang told The Guardian that batteries would not necessarily increase the cost of EVs.
According to the notion, automakers will reduce the size of their batteries, hence lowering costs. The range will be irrelevant when they can be recharged in minutes, presuming infrastructure is resilient and abundant — which it is not, but we’ll get to that.
On the other hand, Mark Ellis of Munro & Associates, a battery expert, warns me that the economics of such batteries remains a major unknown. “No one has calculated how much the initial cost of the electric vehicle would have to raise to accommodate the fast-charge capability,” he says.
While manufacturers may reduce the size of their batteries to make EVs inexpensive, it is unclear how much.
One thing is certain: the chargers required for charging a car battery will be prohibitively expensive.
“Consider how much energy would be required to charge a battery pack for five minutes. It is quite a bit,” Ellis informs me.
Indeed, the more powerful the charger, the higher the development and installation expenses. According to a 2015 report from the US Department of Energy, the cost of installing a basic Level 2 charger ranges between $600 and $12,700. At the same time, installation of direct current fast chargers might cost between $4,000 and $51,000.
Chargers designed for ultra-fast five-minute charging a car battery will likely be much more expensive.
Regrettably, chargers for this type of battery remain a pipe dream. Therefore, let us take a step back and analyze StoreDot’s expectations regarding its battery’s capabilities when charging over modern infrastructure.
By 2025, the company hopes to deliver batteries capable of adding 100 miles of range in five minutes using modern chargers.
While this is commendable, it is far more indicative of the condition of charging today.
StoreDot’s aspirations are only marginally greater than those of today’s fast-charging electric vehicles. Adding 100 miles in just 5 minutes appears to have been the plan all along.
When we look at Tesla, we find a firm leading the charge — not apologizing — in terms of fast electric vehicle charging.
The Silver T claims that its V3 Superchargers, debuted in 2019, can add 75 miles of range in five minutes under ideal conditions.
Tesla has invested billions in charging a car battery infrastructure and is unquestionably the market leader. As a result, Tesla is often the first choice for long-distance EV travel.
Porsche claims that its Taycan can charge its battery from 5% to 88 percent in 22 minutes. This makes it one of the fastest charging EVs on the market — but only under ideal conditions and with the correct charger, which is few and far between at the moment.
Thus, while having a fast-charging EV is desirable, finding the appropriate chargers is difficult. However, this is changing.
Infrastructure is developing, but it will take time to reach its full potential.
The UK installed its 4,000th quick EV charger just this month. A worthy goal, but 4,000 is far from sufficient.
According to the UK think tank Policy Exchange, the country needs to install five times as many EV chargers as it does now to meet demand by 2030, and that’s just conventional chargers, not the super-high-powered ones required for fast charging.
The Netherlands boasts Europe’s fastest-growing EV charging network, but it is still a long way from serving an entire country of electric vehicles. According to Wallbox, the low country has 52,000 chargers, most of which are not rapid chargers.
Ultimately, the onus for installing the necessary technology will almost certainly fall on third-party charging providers. These corporations will install what is in demand, not cutting-edge fringe technology that costs roughly five times as much and benefits only a small percentage of the population.
According to Ellis, battery technology is advancing rapidly, and obstacles are collapsing at the same rate. However, at this point, we cannot predict when this type of technology will reach the mass market. It’s impossible to predict with certainty when this technology will become ubiquitous, as there is simply too much that has to happen for the technology to work in the real world.
It’s all well and good to have a battery that charges in five minutes, but without robust, abundant, and affordable charging, such technology is effectively useless to the vast majority.
A more straightforward and effective strategy would be to simply increase the number of chargers so that when people arrive at their destination, they can plug in, charge, and depart with a fully charged battery. While five-minute batteries are technological advancements, they serve as a safety net.
If every parking space had an EV charger, would we even need batteries with a five-minute charge time?
