California, Stanford University scientists on the 7th in the report that they have successfully coated with a layer of silver carbon LENOVO laptop battery nano-materials of paper into a “paper battery” is expected to become a whole new light and efficient storage methods. Help coating attached to the same characteristics of paper so that it attached to the single-walled carbon nanotubes and silver nanowire thin film. Preliminary studies have found that the use of silicon nanowires made of batteries, the efficiency is now used to power devices such as notebook computer lithium-ion batteries by 10 times.

Scientists published in the “U.S. National Academy of Sciences,” on the paper, said: “Using sophisticated technology, the paper by the sheet of paper with a conductivity as the collector and the electrode can be made into low-cost, lightweight, and efficient TOSHIBA laptop battery power-storage devices. ”

People can use this battery for electronic devices, or hybrid energy supply. Use of such batteries, electronic devices will become lighter, and longer, but one day may produce paper electronic IBM laptop battery products. Weight and battery life of the power cars and trucks in the commercial development faced a major obstacle.

Stanford University associate professor of materials science and engineering and co-authors of this paper Cui Yi (Yi Cui), said: “Our society really needs a low-cost, high-energy storage devices such as batteries and super capacitors simple.” Cui Yi indicated that, in addition to portable electronics and wearable electronic devices you can use it outside, “Our paper super-capacitors can also be applied to all who need instantaneous DELL laptop battery high-power energy equipment. Because of our paper the cost of batteries and super capacitors is very low, they are also applies to the grid of energy reserves. “University of California, Berkeley professor of chemistry Peidong Yang (Peidong Yang) said that the technology will be commercialized in the near future.

T400, compared with the previous T61, in some small details to make a change. Shell joined the Ienovo lower left panel of the words change to display the bottom of the microphone position, while the light bar has also joined the tag antenna; in XY coordinates of the touch pad on the printed line, hot-swappable drive surface using oblique edge design, the keyboard panel lower right corner Thinkpad word patterns have changed IBM Thinkpad T40 battery.

Thinkpad T400 CTO uses Intel Core 2 Duo P8700 2.53G processor, Intel GM45 chipset, 2G RAM, 250G hard drive, DVD burner, 14.1-inch WXGA (1280 * 800) display, an independent ATI Mobility Radeon HD 3470 graphics card, 256M memory, integrated GMA X4500 graphics chip, 14.1-inch WXGA display, built-1000M network card, wireless card, Bluetooth modules. In the interface, the fingerprint system, 3 USB, 1394, VGA, card reader, 6-cell lithium IBM Thinkpad T500 battery, machine weighs about 2.4Kg.

Edit Comment: T400 notebook is very good quality and workmanship, combined with 2.53 GHz P8700 processor and 6-cell IBM Thinkpad W500 battery, the current price of 7200 yuan for such a configuration T400 products, is still very worth buying.

ThinkPad X200’s body size of 295 × 210 × 21-35mm, body weight of 1.53Kg. It uses a 12.1-inch wide-screen design with a resolution of 1280 × 800.

ThinkPad X200 Lenovo K42 battery offers the following body interfaces: 3 USB2.0 port, RJ-45 network interface, a set of audio input / output port, VGA port, ExpressCard slot, card reader.

Network, ThinkPad X200 built-in 10/100/1000M Gigabit Ethernet card and is equipped with 802.11a/g/n wireless card. Life context, which uses 6-cell lithium Lenovo ThinkPad R400 battery-powered, the official nominal life time of up to 6 hours.

Dealer Comments: Lenovo ThinkPad X200-7457CH1 is a very portable business notebook computers, with a stable Lenovo ThinkPad SL300 battery, strong and durable business models and other features, requires frequent out office friends can consider this notebook.
