Supercapacitor breakthrough suggests EVs could charge in seconds but with a trade-off

Published

on

Supercapacitors may be providing an alternative to electric-car batteries sooner than expected, according to a new research study. Currently, supercapacitors can charge and discharge rapidly over very large numbers of cycles, but their poor energy density per kilogram —- at just one twentieth of existing battery technology — means that they can’t compete with batteries in most applications.

That’s about to change, say researchers from the University of Surrey and University of Bristol in conjunction with Augmented Optics. They have announced a breakthrough in supercapacitors, which are said to be between 1000 and 10,000 times more powerful than equivalent lithium-ion batteries and considerably quicker to recharge. However, they lack the storage capacity found in traditional automotive-grade lithium-ion batteries used in today’s electric cars. But Jim Heathcote, chief executive of Augmented Optics Ltd and Supercapacitor Materials Ltd, says consumers would likely still be happy with the trade off by having faster charging times. “A lot of people would be more happy with a half the range of a 300-mile, lithium ion-batteried EV, but a fast charging time”. If their research can be translated into the consumer market, EVs could re-charge in a time quicker than filling a vehicle with a tank of gasoline.

Tesla CEO Elon Musk has remarked in the past about the use of supercapcitors in electric vehicles, “If I were to make a prediction, I’d think there’s a good chance that it is not batteries, but super-capacitors.” The recent research could be a first sign that Musk’s prediction from five years ago could one day come to fruition.

Why a combination of batteries and supercapacitors is essential to a sustainable future

In the next few decades, fossil-fueled cars and home-heating systems will need to switch to electric power to avert catastrophic climate change. Electricity has tremendous benefits but also one significant drawback: it’s relatively difficult to store in a hurry. Batteries can hold large amounts of energy, but they take hours to charge. Capacitors are a solution to this dilemma, as they charge nearly instantaneously.

A supercapacitor solves the problem of storing a reasonable amount of energy for a relatively short period of time. Supercapacitors have been typically used as energy reservoirs to stabilize power supplies to electrical and electronic equipment. But supercapacitors can also be connected to batteries to regulate the power they supply. However, up until this point, they have only been able to store minuscule amounts of energy.

To truly have a feasible electric-powered lifestyle in which we can store and release large amounts of energy very quickly, we need efficiency in both batteries and supercapacitors. Supercapacitors help to solve the “energy versus power” conundrum. “Energy” is the capacity to do work. In physics, work is the act of exerting a force over a distance. While energy measures the total quantity of work done, it doesn’t say how fast you can get the work done. “Power” is the rate of producing or consuming energy. Supercapacitors can bridge that divide and solve the inherent trade-off between EV energy and power.

Dr. Brendan Howlin of the University of Surrey said: “There is a global search for new energy storage technology and this new ultra-capacity supercapacitor has the potential to open the door to unimaginably exciting developments.”

They hope to have a working prototype by spring 2017. “We are now actively seeking commercial partners in order to supply our polymers and offer assistance to build these ultra-high-energy density storage devices,” said Heathcote. In current form, the high energy density supercapacitors could make it possible to recharge mobile phones, laptops, or other mobile devices in just a few seconds.

A fleet of supercapacitor-equipped buses is already in use in China, although they do not achieve the range proposed by the Surrey research team.

Tesla CEO Elon Musk sends final warning to Bill Gates over short position

“If Gates hasn’t fully closed out the crazy short position he has held against Tesla for ~8 years, he had better do so soon,” Musk said.

Tesla CEO Elon Musk sent a final warning to former Microsoft CEO Bill Gates over his short position, which he confirmed he held to Musk directly several years ago.

Gates has been a skeptic of Tesla for some time, but he has also tried to work with Musk on philanthropic opportunities several years ago, which was coincidentally when he admitted to the company’s frontman that he held a short position.

Musk was, in turn, “super mean” to Gates, according to Walter Isaacson’s biography about the Tesla CEO. Gates had put $500 million against Tesla, shorting the stock and hoping to profit from its failure.

Elon Musk explains Bill Gates beef: He ‘placed a massive bet on Tesla dying’

A short position essentially means Gates is betting Tesla shares will go down, which would make him money. However, shares have gone up over six percent this year and increased nearly 150 percent over the past five years.

At the recent Annual Shareholder Meeting, Musk made many claims about Tesla’s future projects and how they could manage to disrupt various industries. He also recently had a massive $1 trillion compensation package approved, which will be awarded in twelve tranches, all of which combine a company valuation goal and an individual goal related to a product.

Musk was able to complete his last approved pay package, but it was not awarded due to a ruling by a Delaware Chancery Court. Nevertheless, his track record of proving growth for Tesla shareholders is excellent, and investors are obviously very encouraged by his capabilities as a CEO, considering 76.6 percent of shareholders voted to approve his new compensation.

After it was revealed that the Gates Foundation dumped 65 percent of its Microsoft position for nearly $9 billion, Musk had one final message for him: drop your Tesla short position soon, or else.

Musk’s rivalry with Gates is mostly founded on the Tesla CEO’s discontent with the former Microsoft frontman’s short position. However, Musk might have a bit of a soft spot for Gates, considering he is giving him a warning of what is potentially to come. If he really wanted to do some damage to Gates, he would not give him any heads-up at all.

Tesla rolls out most aggressive Model Y lease deal in the US yet

With the promotion in place, customers would be able to take home a Model Y at a very low cost.

Tesla has rolled out what could very well be its most aggressive promotion for Model Y leases in the United States yet. With the promotion in place, customers would be able to take home a Model Y at a very low cost.

Zero downpayment leases

The new Model Y lease promotion was initially reported on X, with industry watcher Sawyer Merritt stating that while the vehicles’ monthly payments are still similar to before, the cars can now be ordered with a $0 downpayment. 

Tesla community members noted that this promotion would cut the full payment cost of Model Y leases by several thousand dollars, though prices were still a bit better when the $7,500 federal tax credit was still in effect. Despite this, a $0 downpayment would likely be appreciated by customers, as it lowers the entry point to the Tesla ecosystem by a notable margin.

Premium freebies included

Apart from a $0 downpayment, customers of Model Y leases are also provided one free upgrade for their vehicles. These upgrades could be premium paint, such as Pearl White Multi-Coat, Deep Blue Metallic, Diamond Black, Quicksilver or Ultra Red, or 20″ Helix 2.0 Wheels. Customers could also opt for a White Interior or a Tow Hitch free of charge.

A look at Tesla’s Model Y order page shows that the promotion is available for all the Model Y Premium Rear-Wheel Drive and the Model Y Premium All-Wheel Drive. The Model Y Standard and the Model Y Performance are not eligible for the $0 downpayment or free premium upgrade promotion as of writing.

Tesla is looking to phase out China-made parts at US factories: report

Tesla has reportedly swapped out several China-made components already, aiming to complete the transition within the next two years.

Tesla has reportedly started directing its suppliers to eliminate China-made components from vehicles built in the United States. This would make Tesla’s US-produced vehicles even more American-made.

The update was initially reported by The Wall Street Journal.

Accelerating North American sourcing

As per the WSJ report, the shift reportedly came amidst escalating tariff uncertainties between Washington and Beijing. Citing people reportedly familiar with the matter, the publication claimed that Tesla has already swapped out several China-made components, aiming to complete the transition within the next two years. The publication also claimed that Tesla has been reducing its reliance on China-based suppliers since the pandemic disrupted supply chains.

The company has quietly increased North American sourcing over the past two years as tariff concerns have intensified. If accurate, Tesla would likely end up with vehicles that are even more locally sourced than they are today. It would remain to be seen, however, if a change in suppliers for its US-made vehicles would result in price adjustments for cars like the Model 3 and Model Y.

Industry-wide reassessments

Tesla is not alone in reevaluating its dependence on China. Auto executives across the automotive industry have been in rapid-response mode amid shifting trade policies, chip supply anxiety, and concerns over rare-earth materials. Fluctuating tariffs between the United States and China during President Donald Trump’s current term have made pricing strategies quite unpredictable as well, as noted in a Reuters report.

General Motors this week issued a similar directive to thousands of suppliers, instructing them to remove China-origin components from their supply chains. The same is true for Stellantis, which also announced earlier this year that it was implementing several strategies to avoid tariffs that were placed by the Trump administration.
