Samsung has filed a patent two years ago about a new graphene-based technology which allowed to create batteries able to store a 45% more charge in the same space than a current lithium battery. The patents may not materialize, but it seems that this is the case and Samsung would be ready to launch it in a terminal.
This has been revealed Evan Blass, known for its precise mobile "leaks", which allowed us to see the first real photos of dozens of mobile phones exclusively. Blass revealed that Samsung plans to launch in 2020 or 2021 a mobile phone using a graphene battery instead of a lithium-ion battery.
Thanks to this new battery, the mobile phone would not only increase its density by at least a 45% higher percentage, but would also recharge up to five times faster. load a mobile completely in less than 30 minutes, while it currently takes about two hours for a full charge of 0 to 100%.
Although the charging speed is much higher (for example, it is not wise to use Superchargers continuously in the Tesla), the deterioration of these graphene batteries is lower, so that the durability increases. that the storage capacity increases. Charges over the years. In addition, once production reaches an adequate level, the price of batteries will also decrease.
Another important benefit of these batteries is that they would be very useful. safer. Lithium use a liquid electrolyte which, in contact with the air, come into combustion and cause the battery to burn and explode. In this case, the electrolyte used is graphene, which does not burn on contact with the air.
This would be great news for Samsung, which would have a technology that its rivals do not have and that would allow it to gain even more market share. In the second half, Samsung was responsible for 40% of mobile phones sold in Europe. Its best-selling terminal was the Galaxy A50 with 3.2 million units, followed by the A40 with 2.2 million units.
We do not know anything about the terminal that will include this battery, but it would have limited traffic because Samsung would further increase its production capacity while reducing its costs. Initially, it was planned that the The graphene pile arrived this yearbut eventually, it seems like it will take at least one or two more.
Tesla is not supplied with a serial key, although you can buy one at an additional cost. Instead, you have two options: use a RFID card, which unlocks the car by placing it in the part that separates the driver's door from the passenger's one behind, or using the mobile with the application. The card, which has a chip and a copper filament, can be arranged in a somewhat different way to continue to work, and even implant it in your arm.
That's what a software engineer and youtuber called Friend DD, who already had an RFID tag on his arm to open the door of the house or for a cell phone to open his website when scanning. When he booked his 3 Tesla model, he realized that he could do the same with the car. When he received it, he tried to transfer the information on the chip that he already owned, but in the impossibility of doing so, the only solution was to reopen it and to l & # 39; insert.
To do this, he dissolved the card with acetone and inserted it into a biopolymer capsule that he then inserted into his forearm by going to a specialized clinic. Friend DD has uploaded a video of the process, which you can see below. Eye, there is blood from the minute 1:05, because we see how we make the incision with a tube and we introduce the chip.
It is interesting to note that in the video, the chip does not work, but in principle, it should work without problems. The copper antenna is usually needed to read the chip, but as we see in the second 0:22, the antenna has been redesigned to take up less space.
Although it is not visible in the video, the chip works, as it confirmed on Twitter, although the range is much smaller than that of the card: it is only 3 cm, which is enough for Unlock the car without having to reach the body.
The article mentioned that I had not shown the implant working with my car. The area of the arm is inflamed and swollen just after implantation of the chip. My friend is recording my videos and we did not have time to film the implant together with Tesla this week because I am @defcon ! pic.twitter.com/AkcrIwI8DD

Thanks to that, you will never forget the car key, but thankfully, there are other less "invasive" methods with the human body if we want to carry the car key always above, like a car. RFID ring May we always carry in hand.
This great technological progress has been achieved by the Finnish company ICEYE, which is creating a constellation of satellites to create synthetic images of the Earth during the first capture of images with a precision less than one meter using a small satellite. In the first images captured, you can clearly see how oil is loaded and unloaded in the deposits.
The company was founded in 2015 and has compiled in recent years some $ 65 million in financing. Thanks to this, they have already deployed three of the five satellites that will form the last constellation from 2020 to take these precise photos. Satellites are equivalent in size to a small refrigerator and gravitate around Earth in low Earth orbit.
The first satellite was launched in January 2018 aboard the Polar satellite launcher in India. Since then, they have launched the other two satellites and plan to launch two more by the end of the year. From there, the goal is to launch a commercial service and the reach of these services continues to grow, in addition to having 18 satellites in total over the next 2 years.
How did they reach a precision of less than one meter? The key is in the type of camera. Most satellites that take pictures from the space use optical instruments Like the cameras we use. However, ICEYE It uses synthetic aperture radar technology. The "synthetic" part is due to the fact that a small antenna moving over a long distance can imitate the resolution of a larger antenna.
Basically, we are faced with a radar that uses the movement of this antenna and combines it with the time the satellite flies over a target. multidimensional images from the surface even through the clouds or day and night. The end result is images very similar to those obtained with conventional radar and similar to night vision goggles. At first glance, they may be difficult to interpret, but knowing where to look can offer very valuable information.
Each the radar weighs 100 kg, and the cost of each small satellite is "only" 2 million eurosin front of 100 million They usually cost the normal ones. In the comparison plans, they took real photos with the satellite EU Sentinel-2, which has a resolution of up to 10 meters, or 20 times lower.
Can be used at night or through clouds, this type of satellite can monitor any type of situation or disaster with extreme accuracy. For example, at the beginning of the year, they monitored the breakup of the Brumadinho Dam in Brazil, which killed 248 people. Despite the cloudy sky, they were able to record where the mud was going and the mud dragging the break.
As we have seen in the photos, to demonstrate the accuracy of the satellites, we have analyzed the ports of Nigeria (Port Harcourt) and Australia (Brisbane) with a accuracy of 55 centimeters, able to analyze the oil load in each zone, which can be useful for estimating oil reserves in the world.
Initially, the company wanted to focus on monitoring Arctic thaw for scientific purposes and to ensure the safe passage of goods, but it realized that it had many other uses, such as than that demonstrated by the oil or gas industry, as well as: to monitor natural disasters Who knows what other uses they can discover in the years to come.
Currently, the current batteries are composed of an anode (which is usually graphite) and a cathode, which is a lithium alloy with other metals. Among them, there is a separator, in addition to an electrolyte. When the battery is charging and discharging, it forms lithium oxide at the anode, so you lose lithium able to store the charge. he electrolyte, which is liquid, is a conductive material that helps reduce the harmful effects of dendrite formation in batteries, but reduces their density and makes them flammable.
However, Tesla continues to advance his batteries. The company has already managed to reduce the presence of cobalt in its batteries and its goal is to eliminate it completely. The composition of 2170 batteries that Tesla used last year used a 80% nickel, 10% manganese and 10% cobalt. Later, in the summer, Elon Musk said that they had continued to use only one 3% cobaltand the one at The new generation would do without this rare and expensive material.
Tesla is among its collaborators Jeff Dahn, one of the pioneers in batteries. We owe him, for example, to increase the life of our mobile batteries, and he is currently working on improving the batteries for Tesla. In fact, he said in an interview that he had created better batteries than batteries in the solid state in which companies such as Samsung or LG Chem are currently working and promise to revolutionize electric cars.
The research that they published in Nature Energy, Jeff Dahn and other researchers have managed to create a new lithium-metal battery design no anode thanks to a LiDFOB / LiBF4 double salt liquid electrolyte. The design of these cells is bag-shaped rather than cylindrical like those currently used by Tesla.
It is currently believed that cells with lithium metal anodes are an alternative to current lithium ions, in which the liquid electrolyte must be replaced by an electrolyte in the solid state in order to maintain flat morphologies and without dendrite . However, Dahn states that the elimination of the anode and the use of this LiDFOB / LiBF4 combination allow to achieve a storage capacity of 80% after 90 cycles of full loading and unloading , the longest life demonstrated to date for cells with excess. lithium zero
This means that this liquid electrolyte is totally free of dendrite training, allowing in return Increase the density of the battery and the service life without having to resort to the solid electrolyte, which currently generates dendrites and is not compatible with the current battery manufacturing infrastructure, unlike those created by the team of researchers, which would reduce its price.
The cost of batteries does not stop falling, and Dahn himself recently said in an interview that he expects the cost of batteries to drop below $ 100 per kWh in the coming years, where they currently cost about $ 145 per kWh. Reducing the $ 100 will be a key point, as the manufacture of an electric car will cost less than an explosion.
So, Barcelona will receive the grant from the European Commission for the purchase of a new supercomputer that will be 17 times faster than the current, with help to acquire the material that will be around 100 million euros. This figure would be the largest investment in EU research in Spain so far.
This 100 million will be the half the cost all the necessary material, the other half being provided by the Government of the Generalitat and the UPC. This will be the Barcelona Supercomputer (BSC) who manages this supercomputer as in the current version, in a consortium of the country will also pay countries such as Portugal, Turkey and Croatia, which helped Barcelona to install this equipment in front of the two other countries which will also have these supercomputers: Italy and Finland Ireland could also join the consortium.
The three countries will have these supercomputers called "Pre-excale(Of at least 100 petaflops), and will be the the most powerful in Europe. Currently, the most powerful in Europe is the Piz Daint of Switzerland, which is the fifth most powerful in the world with 21 230 TFLOP maximum power. Then followed the SuperMUC-NG in Germany with 19,476, the HPC4 in Italy with 12,210, the Tera-1000-2 in France with 11,965.5, the Marconi in Italy with 10,384.9 and the Cray in the United Kingdom with 8,218.
Spain is currently ranked 25th with the MareNostrum, with a power of 6,470.8 TFLOP. If we multiply the number by 17 by the Commission, we end up 110,000 TFLOP, surpassing the Sierra of the United States, second country in the world with 94,640 TFLOP. Only the top of the United States would be ahead with 143 500 TFLOP, or 125 petaflops. Thus, Spain will share this second position with Finland and Italy, who will have the same team.
With this, the EU is making a big first step in the European roadmap to supercomputing, in which it wants to become a power that can compete with the United States, China or Japan in this segment, which usually occupies the first seats. This supercomputer in Barcelona will be able to treat200,000 trillion operations per second". The supercomputer will be operational on December 31, 2020and its maintenance will cost 200 million euros for 5 years.
The Supercomputers are the key to an economybecause they are an excellent source of income for dealing with all kinds of tasks. Some of the most used are intended for simulations in the aviation, naval or automotive industry, by the medical industry to study the creation of new drugs or to simulate changes in weather and climate.
The current MareNostrum IV is used by almost 600 scientists which make up the supercomputing center of Barcelona, of which 32% are foreigners. The renewal of the team and the creation of MareNostrum 5 will attract even more talent in Spain. The current supercomputer is housed in an old 160 square meter chapel next to the UPC. Because they need more space, the facilities are extended to a building located right next to it.
Thus, the EU will purchase a total of three supercomputers with more than 100 petaflops to be installed in Barcelona (Spain), Italy and Finland. They will also acquire five other "less powerful" within the petascale.
However, the group behind this invention has some of the most successful pioneers in the world of batteries, one of them being inventors of the lithium-ion battery, John Goodenough, He is already 96 years old and continues his research and publications.
In this case, the research has three other scientists, whose research claims to have succeeded in designing a non-flammable solid state lithium battery using electrolytes-based crystal powder. This battery has twice the density of current batteries (theoretically 6000 mAh battery in the same space of a 3000 mAh current), and with a capacity that increases with time.
Specifically, after 300 charge and discharge cycles, the battery capacity increases to quadruple. If these data were not enough, their sustainability has also raised the eyebrow of many scientists: 23,000 full charge cycles, which is fun, considering those around them. 1000 cycles that a current battery can last.
One of the researchers, Maria Helena Braga from the University of Porto, says that this is possible because her glass electrolyte is a material. ferroelectric, which changes its polarization if a field is applied externally. With this, each change you make, each dipole would find its optimal orientation.
Braga says his group has negotiated with several companies that want to use their licensed technology, but they can not advertise who they are or for which products. What she says is that in addition to being denser, more durable and non-flammable, they can do without the stainless steel insulation to which every cell in the battery is subjected because there is no risk of fire by the chain. they would also lighter than the current ones.
The project continues to move forward, and they claim that for 2022 the first commercial products will be available based on this innovation. With regard to the products we might expect, we can not do more than speculation, such as a manufacturer of electric cars, the storage of excess energy from the production on power grids or mobile phones.
