Supercapacitor breakthrough to bring seconds-long charging to phones, laptops and electric cars

A significant breakthrough in supercapacitor technology looks set to render the humble battery to history, by providing both dramatically increased power capacities and rates of recharge.

The polymer-based technology, which is the result of research by scientists at the University of Surrey, the University of Bristol and Augmented Optics, has been found to be 1,000 to 10,000 times more powerful than existing batteries, and is also more environmentally friendly.

Supercapacitors have long been considered an important technology for future development, providing an alternative to batteries by storing energy using electrodes and electrolytes. This allows the energy to be stored and released for use far more quickly than in standard batteries, but so far supercapacitors have not been able to compete due to the fact that they have poor levels of energy density.

In other words, up until now supercapacitors could store only 1/20 of the energy of batteries per kilogramme, meaning that they were generally too large to be practical.

However, by adapting the principles used to make soft contact lenses – the primary field of Augmented Optics – the scientists have finally developed a material that can not only allow supercapacitors compete with batteries, but offer significant improvements over them.

The advances this supercapacitor technology offers are best explained in terms of electric cars, where it could offer the most dramatic improvements.

A present a standard electric car can get you from London to the nearby city of Brighton – a journey of approximately 55 miles. According to the scientists, this new supercapacitor could allow a car to be driven from London to Edinburgh – a journey of approximately 420 miles – on a single charge. And even when a car is required to recharge, the supercapacitor should allow this process to take just a few minutes, around the same period of time it would take to refill a petrol engine.

“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,” said Dr Brendan Howlin, from the University of Surrey.

However, it’s not just electric cars, or even gadgets, that could benefit.

“While this research has potentially opened the route to very high density supercapacitors, these polymers have many other possible uses in which tough, flexible conducting materials are desirable, including bioelectronics, sensors, wearable electronics, and advanced optics,” explained Dr Ian Hamerton, Reader in Polymers and Composite Materials from the Department of Aerospace Engineering, University of Bristol.

“We believe that this is an extremely exciting and potentially game-changing development.”

Now the scientists have demonstrated the potential of the supercapacitor technology, the next challenge is to develop it into a commercial product.

“The test results from the new polymers suggest that extremely high energy density supercapacitors could be constructed in the very new future,” said Jim Heathcote, chief executive of both Augmented Optics and Supercapacitor Materials.

“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.”

60% of primate species threatened with extinction

A new study has called for urgent action to protect the world’s rapidly dwindling primate populations after figures revealed that 60% of the world’s primate species are threatened with extinction. There are over 500 currently recognised primate species, with the percentage considered at risk having increased by 20% since 1996.

The study draws attention to the incredible impact that humans have placed on primate environments. Agriculture, logging, construction, resource extraction and other human activities have all placed escalating and unsustainable pressure on the animals’ habitats, and are predicted to only worsen over the next 50 years.

Unless immediate action is taken, the scientists predict numerous extinctions.

“In 1996 around 40% of the then recognised primate taxa were threatened. The increase to 60% at present is extremely worrying and indicates that more conservation efforts are needed to halt this increase,” says Serge Wich, professor by special appointment of Conservation of the Great Apes at the University of Amsterdam.

Interestingly, one of the main suggestions for helping the primates is first helping humans. Most primates live in regions characterised by high levels of poverty and inequality, a fact that the study authors believe leads to greater hunting and habitat loss.

They suggest that immediate actions should be taken to improve health and access to education, develop sustainable land-use initiatives, and preserve traditional livelihoods that can contribute to food security and environmental conservation.

While it may be tragic to some, it could be easy to see the loss of these primates as unimportant to humans. However, it is important to note that the non-human primates’ biological relation to humans offers unique insights into human evolution, biology, behaviour and the threat of emerging diseases.

Additionally, these species serve as key components of tropical biodiversity and contribute to forest regeneration and ecosystem health. If they are struck by mass extinction, it is hard to predict the impact it could have on their ecosystems.

“‘If we are unable to reduce the impact of our activities on primates, it is difficult to foresee how we will maintain this fantastic diversity of our closest relatives in the near future,” added Wich. “That will not only be a great loss from a scientific point of view, but will also have a negative influence on the ecosystems that we all rely so much upon. It is therefore important to drastically change from the business as usual scenarios to more sustainable ones.”

The threat posed to delicate ecosystems by human expansion is nothing new, but it is perhaps shocking to have such a blunt figure out there as to the damage being caused.

More than half of these species – species that are far closer to us than we may be comfortable discussing – could die unless current policy is reversed.

The study’s authors have called on authorities across the world to take action and raise awareness of the issues raised.

The article itself is published in the latest edition of the journal Science Advances.

Mark Zuckerberg: VR goal is still 5-10 years away

Mark Zuzkerberg has said that the true goal of virtual reality could still be a decade away, in a testimony during a high-profile court case against his company.

Facebook, as owner of Oculus, is currently in the middle of being sued by ZeniMax Media for allegedly stealing technology for the virtual reality device. If proved guilty, they will be pursued for the amount of $2bn by ZeniMax.  However, perhaps more pertinent to the actual future of virtual reality are comments arising from Mark Zuckerberg’s testimony.

As it currently stands, virtual reality is still a far cry from being integrated into everyday life on a wide scale. Oculus, HTC Vive and Playstation VR are still largely targeting gamers and the idea of entertainment experiences. While they have found varying levels of success, all three platforms are being held back by the youth of the technology and, in the case of Vive and Oculus, the limited by the need for a high performing computer to plug into.

“I don’t think that good virtual reality is fully there yet,” said Zuckerberg. “It’s going to take five or 10 more years of development before we get to where we all want to go.”

The revelation isn’t a particularly shocking one; even the most ardent believer in virtual reality has to admit that we’re a fair way off the goal. Indeed, we can be seen as being in the first wave of mainstream virtual reality, with the main players in the tech using gaming as a way to introduce the technology to a group that are most likely to be interested from the off.

Zuckerberg has far grander plans than simply expanding the user base however, as seen with projects such as Facebook Social VR. If games are the entry, the idea is to expand virtual reality to become a whole new computing platform used for a bevy of experiences and containing a whole load of tools. The ambition is high, the reality slightly lagging behind.

When asked about the realisation of VR as this new computing platform, Zuckerberg replied: “These things end up being more complex than you think up front. If anything, we may have to invest even more money to get to the goals we had than we had thought up front.”

He then went on to add that the probable investment for Facebook to reach that goal is likely to top the $3bn mark over the next ten years. Considering the social media giant spent $2bn just to acquire Oculus, this represents a truly colossal investment in something that seemed to be initially set to hit a lot sooner. Admittedly the goal is rather grand: providing hundreds of millions of people with a good virtual reality experience transcending gaming alone.

Oh, and in case you were wondering, it’s very important that you know that Mark Zuckerberg did in fact wear a suit to trial. Whether Palmer Luckey, making his first public appearance since his Gamergate/Trump support scandal last year, will manage to ditch the flip flops when he testifies is yet to be seen.
