Tiny lithium-ion battery recharges 1000x faster than rival tech, could shrink mobile devices

Researchers devise 'most powerful' batteries in the world, shame supercapacitors

Supercapacitors are often hailed as the holy grail of power supplies, but a group of researchers at the University of Illinois have developed a lithium-ion microbattery that leaves that prized solution in the dust, recharging 1,000 times faster than competing tech. Previous work done by Professor William P. King, who led the current effort, resulted in a fast-charging cathode with a 3D microstructure, and now the team has achieved a breakthrough by pairing it with an anode devised in a similar fashion.

The resulting battery is said to be the most powerful in the world, avoiding the usual trade-off between longevity and power while having a footprint of just a few millimeters. By altering its composition, scientists can even optimize the contraption for more juice or increased life. It's expected that the technology could make devices 30 times smaller and help broadcast radio signals up to 30 times farther, but it'll still be a while before it winds up in a super-slim phone within your pocket. For now, the researchers have their sights set on integrating the tech with other electronic components and investigating low-cost manufacturing.

Microsoft Surface updates out now, make apps load faster

Updates are out now

Microsoft's Surface tablet has just got its first firmware update, and it's good news if you're short of time.

Apps load around two seconds faster than without the update, according to a tester over at The Verge. That should be pretty noticeable, and should make a big difference if you're using apps a lot.

The bad news? The audio stuttering that users spotted previously hasn't been fixed. So your device may still be subject to random muting and jogging of sound.

The software fix also won't have addressed the Touch Cover issues the Surface has been suffering. A lot of users have been reporting the edge of the Touch Cover has been fraying, exposing wiring. Microsoft has confirmed it's been dealing with "a lot" of Touch Cover returns.

As well as overall slicker performance, the firmware update should fix some security flaws in the Internet Explorer browser, as well as the Windows RT OS itself.

Microsoft has also released an updated version of the Microsoft Windows Malicious Software Removal Tool on Windows Update, Microsoft Update, Windows Server Update Services, and the Download Center.

Have a look at the Microsoft Security Bulletin for more info.

Microsoft Surface launched at the end of October. It runs Windows RT at the moment, but a version running Windows 8 should be out in the new year.

Microsoft surprised and annoyed its partners with Surface, using its insider knowhow to make a competitor product. Hopefully it'll spur everyone on to make better tablets, benefitting the consumer.

Samsung's new 10nm-process 64GB mobile flash memory chips are smaller, faster, better

Samsung Introduces Advanced Memory Storage Solution for Slim Smartphones and Tablets
SEOUL, Korea on Nov. 15. 2012

Samsung Electronics Co., Ltd., the world leader in advanced memory technology, today announced a next-generation 64GB embedded multimedia card (eMMC) using 10 nanometer (nm)-class* process technology. The new 64Gb NAND memory went into production late last month.

Myungho Kim, vice president of Memory marketing, Device Solutions, Samsung Electronics noted, "The new high-speed, small form factor eMMC reinforces Samsung's technology leadership in storage memory solutions. We look forward to expanding our line-up of embedded memory solutions in conjunction with the new chip's design, in pursuing a system-level adoption of application processors and other key components that form the foundation for the most advanced mobile platforms. This will allow us to better attend to time-to-market demands enabling the design of more convenient features for next-generation mobile applications."

Embedded memory is the key memory component in popular mobile applications such as smartphones and tablets. Advanced high-performance, high-density eMMCs allow users to access high-density and high-resolution content such as full HD video on their latest mobile devices and provide a better user experience for web browsing, gaming and running rich applications.

Samsung is applying 64Gb high-performance NAND memory using its10nm-class technology to the new 64GB eMMC Pro Class 2000 memory solution. The new embedded memory solution exceeds the performance levels of the conventional 64GB eMMC Pro Class 1500 based on an eMMC 4.5 interface.

The new high-speed eMMC will be submitted next year to the industry standards body JEDEC, (Joint Electron Engineering Council) for adoption as an industry standard.

Samsung's next-generation 64GB eMMC Pro Class 2000 comes just five months after the company introduced its first embedded memory supporting the eMMC4.5 interface and delivers a 30 percent advantage in performance over that solution.

The 10nm-class technology based NAND also is process compatible to Samsung's advanced 20nm-class* 64Gb MLC NAND, which was first available last May, improving manufacturing productivity by 30 percent.

The new memory solution has a random write speed of 2,000 IOPS (input/output per second) and a random read speed of 5,000 IOPS. In addition, sequential read and write speeds are 260 megabytes per second (MB/s) and 50MB/s respectively, which is up to 10 times faster than a class 10 external memory card that reads at 24MB/s and writes at 12MB/s, greatly enhancing the smoothness of multitasking on mobile gadgets.

Current mobile applications show a distinctive trend to slimmer designs and larger display screens, while using advanced multi-core processors and high density (2 Gigabyte) LPDDR2 memory for higher performance, with larger batteries for longer usage on a single charge. This new chip accommodates the increasing size limitations of mobile form factors at the component level.

The 64GB eMMC Pro Class 2000 measures 11.5mm by 13mm, which represents a 20 percent reduction in size over the conventional embedded memory form factor (12mm by 16mm).
