New Solid-State Batteries From Samsung/MIT Could "Last A Lifetime"

Batteries. We need them for almost everything we use. They're in our laptops, our smartphones, our video game controllers, our remotes, and anything we use that is now wireless. But the one thing wrong with batteries in today's world is that they are finite. Eventually, they will run out of power and there's not a whole lot we can do about that. Or is there?

Researchers have recently developed a new material for a basic battery component that, according to them, will allow almost any battery indefinite power storage. This new material, known as a solid electrolyte, could increase battery life as well as battery storage capacity and safety as liquid electrolytes are the leading cause of battery fires.

The standard lithium-ion batteries that we use today use a liquid electrolyte. This liquid electrolyte is an organic solvent that has been known to overheat and cause fires in things like cars, commercial airliners and even smartphones. With a solid electrolyte, there is absolutely no safety problem whatsoever.

According to Gerbrand Ceder, a professor of materials science and engineering at MIT and one of the main researchers on the project, "You could throw it against the wall, drive a nail through it - there's nothing there to burn." In addition to that, a solid-state electrolyte will have virtually no degradation, which means that such batteries could last through "hundreds of thousands of cycles," Ceder continued.

Organic electrolytes also have limited electrochemical stability, which means that they lose their ability to produce an electrical charge over time. In addition to MIT, scientists from the Samsung Advanced Institute of Technology, the University of California at San Diego and the University of Maryland also conducted research on the project.


The findings were published in the peer-reviewed journal Nature Materials and the researchers described the solid-state electrolytes as an improvement over the current lithium-ion batteries we are using today. Electrolytes are one of three main components in a battery along with anode and cathode terminals.

The electrolyte component of the battery separates the battery's positive cathode and negative anode terminals while allowing the flow of ions between terminals. A chemical reaction then takes place between the two terminals, producing an electric current.

Previous problems with solid electrolytes are that they were incapable of conducting ions fast enough to be efficient energy, producers. The team of researchers from MIT and Samsung say that they have overcome that problem. Another advantage of a solid-state lithium-ion battery is that it can perform under very cold temperatures with Ceder calling this breakthrough "a real game-changer" that creates an "almost perfect battery".

The Future Of Technology Could Change As Silicon Goes Down, And Graphene Goes Up!

Here's something that we never normally think about. Whenever you are surfing the web on your laptop, playing Angry Birds on your tablet, or playing Black Ops II on your Playstation 3, do you ever stop and think what is making all of that technology work? 9 times out of 10 the answer is going to be a no. We don't ever really think about how something works as long as it works. However, inside your favorite devices are multitudes of different transistors and microchips that make it possible for your tech to do what it does. Almost everything it mad out of something called silicon. A readily available resource that is conductive enough to have everything work properly, but not conductive enough to fry all of the electronic inner workings. While silicon is definitely the "go to" resource for any real tech company, our friends over at Samsung may have found something that could knock silicon off of the map

Is anyone familiar with something called graphene? No? Not shocking as it isn't something that tech companies use very often.

Graphene is a pretty amazing little material. We are talking about something that is actually HARDER than diamond and with only the thickness of an atom. It's conductivity levels are through the roof and has the potential to, ultimately replace silicon. The only limitation that has been found with this amazing little metal is it's size. Because of it's small size, the qualities that it possesses can't really be replicated and mass produced to benefit electronic products for consumers. Samsung however may have cracked the code to the whole "miniscule" problem.

Researchers at some of Samsung's facilities have found a way to grow the crystal on a "large area, single crystal wafer scale". What does this mean exactly? One word: Synthesize. Simply by finding a way to "grow" and copy, or synthesize, the graphene crystal, Samsung has effectively created a way to properly utilize the material despite its small stature. Now, while synthesizing most materials tends to deteriorate some of the materials natural properties, that hasn't been the case for Samsung's graphene endeavors. By synthesizing the material upon a semiconductor, it has been able to retain all of it's properties without deteriorating later.

Samsung isn't new to graphene either. It's in almost every display to date. That iPad or iPhone that you're reading this article on? Yup. Graphene in it. There is one drawback to the material though, aside from the small size. The fact that it is SO conductive that it's almost TOO conductive. There is no real "energy gap" like with silicon. Since this material is so super conductive, it almost can't really be turned "off", even with the help of transistors. The transistors are what is used to help maintain power within the materials so that they don't fry the inner workings of the devices. Remember, there can be a thing as too much power.

Some scientists within the Samsung research facilities might be onto something when they say that they could "dope" the material. By "doping" it, they'll add chemicals to the material in order to tone down it's conductive nature, however testing is still going on as they aren't sure how the "doping" will affect the other properties.

Silicon is slowly becoming more and more scarce, and graphene is starting to looking really inviting. Should Samsung be able to work graphene into their products and start becoming more reliant on that instead of silicon, we might be in for a very different future in terms of our technology.

Samsung Unveils New Quad-Core Exynos Processors

Samsung has just displayed a new processor at the International Solid-State Circuits Conference. The new Exynos chip will be available in dual-core or quad-core configurations with 200MHz to 1.5GHz frequencies. In addition to that, the new Exynos chip is a 32nm part unlike the current Exynos chip which is only a 45nm process. This smaller footprint also means that the chip will have a higher performance and less power consumption for the same clock speeds.

Samsung is pairing this new chip with the latest version of the company's very own graphics chip, which has 4 pixel processors and 1 geometry engine with 128 KB L2 cache. The graphics will also support OpenGL ES 2.0 and can also generate up to 57 MPolygons/s. Considering that Samsung recently announced new low power DDR3 memory, it isn't surprising to see that this CPU also has support for LPDDR2 or DDR3.

According to the company, this chip will be able to deliver up to 26% more performance than the current Exynos chip and will also be able to deliver battery life improvements of up to 50% with a 45% power save for CPU tasks and 48% for 3D calculations. These comparisons seem to be made with the dual-core chip and it will also be interesting to see how the quad-core chip compares. Samsung is expected to officially announce the chips at the upcoming Mobile World Congress in Barcelona so we will surely find more information there.

It is also expected that Samsung will begin shipping these chips to customers and retailers in the next couple of months, bringing quad-core performance with more battery life to all. Samsung has also stated that this new version of the Exynos was designed with power consumption in mind unlike the current chip which was built around performance.

Upgraded Samsung Series 7 Gamer Laptop Set to Hit U.S. in April

Samsung Series 7 GamerUs laptop gamers here in the states have been pretty envious of our European brothers as they have had the privilege of buying the Samsung Series 7 Gamer notebook since last spring. Well, this spring (April, to be specific) that envy dies and becomes reborn as jubilation as Samsung will be shipping the Series 7 Gamer to us Yanks while giving it a nice increase in specs at the same time.

The 17" gaming laptop will still have the same aesthetics, as well as the same external features, as its European counterpart, including the 2.1 speaker setup with down-firing Subwoofer, super-bright screen and that big knob thingy that switches the device between power modes, like the Gaming Mode, which clocks up the CPU turbo mode, changes the keyboard backlighting, disables the Windows key and a few other things. The only real external difference is the lack of a 3D display option and the addition of a DisplayPort output.

Crack this bad boy open and you will be able to find the differences. On the inside the Series 7 Gamer gets a nice new set of parts. The second generation Intel Sandy Bridge Core i7 processor is gone, replaced by a quad-core third-generation Intel Ivy Bridge Core i7 processor instead. In addition to that, the graphics have received an increase from the Radeon HD 6970M to the upcoming GeForce GTX 670M. You will still have a Blu-ray drive as well as the 2TB hard drive so nothing's new there.

You will be able to grab this mobile gaming giant when it is released in April for a reasonable $1,799, or whenever Intel's high-end Ivy Bridge chips and Nvidia's next-generation GPUs are ready to go, which we hope is by April because, honestly, we can't hold out on this laptop forever.

Samsung Introduces New Galaxy Tab 7.0 Plus

Samsung Galaxy Tab 7.0 PlusSamsung has just confirmed that another variation of its Samsung Galaxy Tab will be hitting stores soon. This new device, known as the Samsung Galaxy Tab 7.0 Plus, will begin selling on November 13, 2011 at many U.S. retailers for a surprisingly reasonable $399.99 according to a statement released by Samsung.

The 16GB tablet, complete with 7" screen, is focused more on home entertainment than business usage, coming complete with a Peel Smart Remote TV app that allows you to tap on the screen in order to quickly find and watch television shows on any manufacturer's TV or home entertainment system.

In addition to that, built-in infrared in the tablet allows you to control a home theater or television setup. The best part is that you don't need any extra cables or hardware, just what you already have in your living room and the tablet, in order to control the TV functions. The Peel remote app allows you to have full control over your TV or entertainment system regardless if it is Samsung brand or not.

Aside from controlling your DVD player, Blu-Ray player, set-top box or TV, the Galaxy Tab 7.0 Plus will also connect to Facebook and Twitter allowing you to share information about what is being watched. According to Chief Experience Officer for Peel Greg Lindley, "Peel's vision is eliminating the barriers between you and your favorite shows."

The Samsung Galaxy Tab 7.0 Plus runs on a 1.2GHz dual-core processor as well as Android 3.2 Honeycomb for an operating system. The device is also only .39" thick and only weighs 12.1 ounces.

Samsung has a plethora of tablets that come with either WiFi only or WiFi and 3G/4G connectivity. According to the website, the Galaxy Tab 7.0 Plus features both cellular and WiFi capabilities though Samsung has yet to announce which U.S. wireless carriers will support the tablet.

The original Galaxy Tab ran on Android 2.2 and upgraded to 2.3 back in May. It too had a 7" touch screen but was slightly larger and heavier and only came with a 1GHz processor. Sales of the Samsung Galaxy Tab Plus will begin on November 13 nationwide at Best Buy, Amazon, tiger Direct, Fry's and other outlets with pre-orders becoming available on October 23.

Samsung's New 30nm DDR3 DRAM

Samsung has just recently introduced 30-nanometer-class1 DDR3 synchronous dynamic random access memory (DRAM) modules designed for upgrading your PC. This new generation of faster, energy efficient DRAM modules is going to be available via consumer retail channels this summer.

According to Samsung Electronics America's Senior Vice President of Mobile Entertainment Marketing Reid Sullivan, "Replacing your DRAM can be one of the easiest, most cost-effective ways to upgrade your PC's performance, and these new products offer the most energy-efficient option currently available to consumers. Samsung is committed to bringing performance-enhanced computing to consumers, and our 30nm-class process technology offers an outstanding combination of advanced low-power DDR3 technology, with blazing speed up to 1,600 megabytes per second."

You can get this new DRAM from Samsung in either a 2GB or 4GB model and both are available in very low profile unbuffered dual in-line memory module configurations for desktop PCs and small outline DIMM configurations for notebook PCs. They are also backwards compatible with systems designed for previous DDR3 and DDR2 memory and can be purchased in single or dual pack quantities.

These memory sticks are also more energy efficient, using up to two-thirds less energy than those manufactured with industry standard 60nm class technology. What is great about that is that this boost in energy efficiency does not come at the cost of performance. The new modules transfer data at up to 1,600 Mbps which is 20% faster than the current 40nm-class generation of DDR3 DRAM from Samsung.

The new 30nm-class DDR3 DRAM modules will be available from Samsung this summer with single pack modules costing less than $30 to less than $55 and dual pack modules ranging from less than $55 to less than $110.
