Battery powered future coming

Success in battery innovation would be in reducing costs and weight to increase performance, an expert has said.
"The next big thing is to successfully reduce the cost in camcorder batteries and a reduction in the amount of time to charge," CSIR manager of the energy and processes and conference chair Dr Mkulu Mathe told News24 at the International Battery Association conference in Cape Town.
Delegates from around the world at the conference discussed ways that batteries can be improved for high-capacity applications such as electric cars. This would have knock-on effects in areas like cellphone and laptop battery packs in terms of charging time, weight and capacity.
"Knowledge is old; thinking is innovative," said Mathe. "There are concerns around cost and the variation of the chemistry. If the weight can go down, it will improve performance, but it's an area that continues to pose challenges."
The biggest modern leap in battery technology came with the introduction of the lithium-ion digital camera battery. Dr Michael Thackeray, John Goodenough, and co-workers identified manganese spinel as a cathode material in 1983.
New technology
"After the introduction of the lithium-ion cell phone battery in 1991, it's been improved by a factor of two. There's been a lot of engineering and now it's starting to plateau," said Dr Steven Visco of PolyPlus Battery Company in California.
"We could think about silicon and package it better," said Professor M Stanley Whittingham of Binghamton University in New York. He first proposed lithium-ion dell laptop batteries in the 1970s.
They warned though, that simply introducing new technology was not a simple matter and there was a time lag before the technology was widely adopted.
"New technology will take 15 to 20 years to come to the market," Visco said.
He also cited the introduction of hybrid vehicles like the Toyota Prius which initially sold poorly before becoming a synonymous with environmental responsibility.
The introduction of zero emission electric vehicles has also had hiccups, as the public charging infrastructure is not yet in place to make these vehicles widely practical.

HTC Desire Z Review


You might be forgiven for thinking the HTC Desire Z is the misunderstood second cousin in the HTC litter. When the Taiwanese manufacturer already has the Desire, the Desire HD, the Desire S and more, it’s hard to get your head around just why you should care about the Desire Z. But the Desire Z truly offers something the other models don't -- a physical keyboard. Is it enough to help the handset shake its family competitors off and pave a path of its very own through life?

The Desire Z fits squarely into what we are rapidly coming to know as HTC’s mobile phone design ethos. The handset is composed of black, silver and grey interlocking pieces, with some sections appearing to be hard plastic and some appearing to be aluminium.

Like the original HTC Desire – released in Australia in April 2010 – the Desire Z has five front-facing buttons underneath its brightly lit touchscreen – the standard Android home, menu, return and search buttons. Unlike the original Desire, these buttons are not physical but are embedded in the phone’s screen – they’re touch-sensitive and vibrate by default when you touch them.

There is also a larger button which is directionally sensitive and can be used to navigate around the phone’s interface if you don’t like touching its screen. Around the sides of the Desire Z are the sort of ports and buttons you would expect – volume controls and USB port on the left, camera button on the bottom right (the right spot if you’re holding the phone horizontally to take a shot) and a 3.5mm headphone jack and power/wake up button on the top.

On the back of the phone are its camera (with flash) and there are speaker grills littered around the place. We liked how easy it is to remove the Desire Z’s cell phone battery or change the SIM card, with a little toggle flipping open a compartment on its back.

MacBook Air too pricey? Thin HP laptop hits $399



Hewlett-Packard is offering a good deal on a well-received ultraportable that is less than half the price of Apple's least expensive MacBook Air.

HP Pavilion dm1z is inexpensive and faster than a Netbook.
(Credit: Hewlett-Packard)

There is discounted hp notebook batteries at aussie-battery.com - your professional battery supplier in australia. Some popular batteries: Dell Latitude D820 Battery, Dell D5318 Battery  and many more.

Why the mention of Apple's MacBook Air? Apple's 2.3-pound laptop is the standard by which all other ultraportables are judged. Like it or not, that's the way things are.

But let's get to the topic at hand. The HP Pavilion dm1z can be had for as little as $399 direct from HP after inputting a coupon code. That's a pretty good deal for a laptop that is a cut above an Intel-based Netbook and offers fairly solid build quality. (See this thorough review of the dm1z here.)

The dm1z, like the smallest MacBook Air, has an 11.6-inch screen, though it weighs over a pound more at 3.5 pounds. That's still pretty light. But it won't match thinness of the Air, which is 0.11 inches at its thinnest point. The HP is 0.8 inches at its thinnest point.

But there are other goodies that compare favorably to the Air. A roomy 320GB hard disk drive (7200RPM), 3GB of memory, more ports, and the option for built-in 3G from Verizon, AT&T or Sprint.

But the comparison with the MBA falters a bit in some crucial areas. The dm1z is not constructed from aluminum like the Air and aesthetically doesn't offer the elegance of the MBA.

Inside the dm1z taps Advanced Micro Devices' latest dual-core E-350 processor (1.6GHz, 1MB L2 Cache with AMD Radeon HD 6310M graphics). These new AMD chips--replete with a solid graphics processor--handily beat Intel's Netbook-class Atom processors but are not necessarily faster than the silicon used in the MacBook Air. The Air pairs Intel's Core 2 Duo processor with an Nvidia chipset that also delivers good graphics performance for an ultraportable.

And returning to the $999 MacBook Air, in addition to the specs mentioned above, you get a 64GB solid-state drive and 2GB of memory.

Laptop Battery life between the two seems comparable. Of course, that depends on what you're doing with the devices, but both exceed five hours, according to most reviews.

No, it's not a MacBook Air. But then again you're saving $600 for a respectable ultraportable--while the coupons last.

Hybrids, electric cars provide different advantages

We're all trying to do more with less these days, and many families are examining their impact on the environment, both at home and on the road. • Electric and hybrid cars have been garnering much attention for having a smaller impact on the environment than traditional gas-powered vehicles, but how do you know whether an alternative energy vehicle is right for you?

Before choosing a new car, it's helpful to understand the differences between hybrid and electric vehicles.

Both types of vehicles are more efficient than traditional cars — incorporating energy-saving and emissions-reducing features, many of which are related to innovative uses of lighter-weight plastics and reinforced plastic composites.

Hybrid cars are dual-powered, featuring an electric motor and a gas-powered engine. The electric motor is powered by a battery, while the gas engine is, of course, powered by gasoline. Depending on how and where you are driving, the car switches between the motor and the engine to achieve maximum fuel efficiency and reduce emissions.

Looking for batteries? we supply digital camera batteries, camcorder batteries and other batteries. Brand new and high quality.

Electric cars, meanwhile, rely on only an electric motor powered by a battery. As battery technology advances, these batteries are getting more powerful and less bulky and are holding charges longer. The latest example of battery technology is the lithium-polymer (polymer means plastic) battery. These batteries are up to 10 percent more efficient than the nickel-metal hydride batteries currently in many hybrid cars.

Electric cars have come a long way, but so far they don't have the same long-range capabilities of gas-powered vehicles. With hybrids, consumers can get the reduced emissions of an electric motor, plus the long-range capabilities of a gas-powered engine.

canada battery shop's hot batteries of today: TOSHIBA PA3395U-1BRS Laptop BatteryLG SQU-524 Laptop Battery and more.

Automakers also are increasing the efficiency of hybrid and electric cars by investing in more efficient designs. They are using materials such as reinforced plastic composites that can be as strong as steel, yet lighter, to reduce vehicle weight and lighten the load on engines. Vehicles built using these materials tend to weigh less, while providing high performance.

And the green credentials don't stop at the engine. Some new models even have seat belts made from recycled plastic bottles. For more information about how plastics are fueling auto innovations, visit www.plasticsmakeitpossible.com.

So which type of vehicle is right for you?

Today's hybrid car models are great for commuters and road trips, while electric cars are handy for short trips to the grocery store or to pick the kids up from school.

Tesla Teams with Panasonic to Boost Electric Car Battery Life

Palo Alto, California-based electric car company, Tesla, is pioneering some of the most innovative advances in electric car technology. Not only that, but Tesla vehicles are actually cool, sporty, and fast. The problem, however, that has plagued Tesla and other electric car manufacturers is battery life. Now, the company is teaming up with tech specialists at Panasonic Corp. to develop a longer lasting battery.

Currently, Tesla’s sporty Roadster model cars can travel up to 245 miles on a single charge. But next year, Tesla is planning on releasing its Model S—a four-door sedan—and wants the car to travel even further on a single charge. The company would like to see the Model S traveling at least 300 miles per charge.

We supply kinds of panasonic batteries with high quality battery cells: panasonic camera batteries, panasonic camcorder batteries and panasonic cordless drill batteries.

Tesla already boasts the most powerful batteries among commercial electric car models, and even supplies its components to some competitors, such as Toyota Motor Corp. and Daimler AG. “Our battery pack has 56 kilowatt hours of energy. Other EVs on the market have about 20 or 24 kilowatt hours,” says Kurt Kelty, director of battery technology for Tesla.

The Model S sedan will also be easily capable of switching out a used battery for a fully charged one. In trying to address battery charging times—which can take several hours—the electric vehicle industry has come up with the solution of battery exchange stations. The Model S will be able to pull into one of these stations and in a matter of minutes have a charged battery replacement ready to take the driver another 300 miles.

You may find battery charger for camcorders, here are some for your choice:  KODAK Easyshare M1073 IS ChargerNIKON EN-EL7 ChargerHITACHI DZ-MV208E Charger and many more.

Three versions of the Model S will be released with three different price tags based on battery life. The basic Model S will only have a range of about 160 miles and will cost $49,900 after a $7,500 federal tax rebate. The second option will be $10,000 more, with a range of 230 miles. The 300-mile range Model S will cost $20,000 more than the basic model.

In early 2010, Panasonic Corp. invested $30 million in Tesla through stock purchases. Since the investment, Panasonic and Tesla have combined their battery technologies to create high-power, longer charge lithium-ion batteries. The 3.1Ah battery cells that resulted from the collaboration are the highest energy density cells commercially available on the market. Now, the two companies are at it again, looking to push the limits of battery life even further.

ThinkPad x220 Review – Editor’s Choice Ultraportable w/ 15 Hour Battery

The Lenovo ThinkPad x220 is a new 12.5″ ultraportable notebook that will be available for purchase in April. We’ve had a chance to use the ThinkPad x220 as our primary notebook for the past several weeks and we have been blown away by what this 2nd Gen Core i5 powered ultraportable can do all while delivering up to 15 hours of real world battery life! If you want to buy lenovo laptop batteries, buy-battery.ca is your best choice.

ThinkPad X220 Review


The x220 is the update to the popular ThinkPad X201 ultraportable, which incorporates several new design changes and features that really complete the user experience. There is also a Lenovo ThinkPad X220t, convertible tablet coming with similar spaces and pricing.

You should head over and check out our full ThinkPad X220 Review, where you’ll learn why we gave this ultraportable our Editor’s Choice award, but in short this is one of the first ultraportable notebooks we have used that could work as the only notebook you have — and with a starting price of $889 you’ll be amazed at what it can do.

This was one of the first Sandy Bridge systems we have had a chance to use and we wanted to test out the integrated graphics so we loaded up Just Cause 2 and were surprised to find a playable game on medium settings. The X220 wouldn’t be our first choice for a gaming notebook, but it is able to transition from work to play without any trouble.

The keyboard is, like on all ThinkPads, really great with a nice feel and layout of keys, but the mouse stole the show on the x220. It’s not that the mousepad si perfect, but it is 45% larger than the x201 and is a clickable surface so you can click anywhere on the upper portion for a left click, much like on a MacBook. The integrated buttons are curved at the base to fit the lid’s slight curve and delivers a passable two finger scroll.

The ThinkPad X220′s battery life, with the optional 19-cell slice battery, was also impressive. When we combined the standard 6-cell battery with the $179 slice battery, we were able to get 15 hours of battery life while surfing the web. The standard 6-cell was able to get just under 8 hours of battery life. If you opt for the 9 cell battery and 19-cell slice battery you can reportedly achieve 20 hours of real world use.

If you’re looking for a great new ultraportable, that weighs in at under 3 pounds with  12.5″ IPS display and a starting price under $900, you need to read our in depth Lenovo ThinkPad X220 review.

Advanced Battery Technologies Announces 2010 Year End Results

NEW YORK, March 21, 2011 (GLOBE NEWSWIRE) -- Advanced Battery Technologies, Inc. (Nasdaq:ABAT), a leading developer, manufacturer and distributor of rechargeable Polymer Lithium-Ion (PLI) laptop batteries as well as a manufacturer of electric vehicles, today announced financial results for the year ended December 31, 2010.

Total revenues of $97.1 million for 2010 represented an increase of $33.6 million or 52.8%, compared to $63.6 million for 2009. The increase in revenues was primarily due to the contribution of sales from the electric vehicle business, which the Company acquired on May 4, 2009. Sales of electric vehicles for 2010 were $49.2 million as compared to $20.3 million for 2009. The increase in vehicle sales was attributable to (a) the fact that 2009 results include only the period from May 4, 2009 to December 31, 2009, and (b) efforts by our management to make Wuxi ZQ more responsive to the requirements of its distributors. There are many high quality cordless drill batteries at aussie-battery.com

Mr. Zhiguo Fu, CEO of ABAT, stated, "We are pleased to report an increase in our revenue attributable to electric vehicles and medium batteries. This has been beneficial to the profitability of our overall business. In order to meet higher demand from both dewalt battery and electric scooter markets, the company intends to accelerate growth by building more facilities and expanding our marketing network."

Gross profit for 2010 was $45.9 million, a 61.7% increase from $28.4 million for 2009. The increased profitability of our sales is mainly attributable to improved production efficiencies in our electric vehicles operations. Since the acquisition of Wuxi ZQ in May 2009, we have worked aggressively to control production costs at Wuxi ZQ. As a result, the gross margin on our sales of electric vehicles was over 40%, compared to 33% in 2009. The overall result was an increase in our gross margin from 44.7% in 2009 to 47.3% in 2010.

Net income attributable to common shares increased 68.5% to $36.7 million in 2010 from $21.8 million in 2009. Diluted earnings per share were $0.48 for fiscal year 2010 compared to $0.36 in fiscal year 2009. At December 31, 2010 the Company had a strong balance sheet, with $111.1 million in cash and cash equivalents and a working capital balance of $131.2 million. The primary reason for the improvement in working capital and cash was the strong positive operating cash flows and the equity offering the Company completed in December 2010.
