Disruptive technologies: Lithium-ion batteries

Welcome to a Laptop Battery specialist of the IBM Laptop Battery First post by: www.askbattery.com

"To compete with advancing gasoline/diesel engines, EV traction batteries have to be much more than twice as energy dense as lithium-ion ever will be, at least three times cheaper, and last much longer before replacement," states a recent TrendTracker report. Dell P769K

So, does that mean that lithium is a dead end technology? What will it take to make lithium a truly disruptive technology?

Apples to apples, lithium-ion battery technologies simply don't compare to gasoline powered internal combustion engine vehicles. It's just not yet in the elements. That chemical reality has been acknowledged by many in the battery segment. Lenovo IdeaPad Y450 battery

For instance IBM Almaden Researchers working on future batteries note, "Since the efficiency of electric propulsion systems (battery-to-wheels) are about 90%, a 10-fold improvement of the current energy densities of Li-ion batteries, which are typically between 100 and 200 Wh/kg (cell level), would bring electric propulsion systems on-par with gasoline, at least as measured by gravimetric energy density. However, there is no expectation that current batteries such as Li-ion will ever come close to the target of 1700 Wh/kg. New chemistries are required to achieve this goal." HP HSTNN-IB25

No problem, right? Just tweak the solution in that beaker, son.

To resolve this problem, IBM researchers have been working on more futuristic battery technologies, such as lithium- air batteries. HP 628419-001 To wit IBM notes, "the requirements for large capacity automotive propulsion batteries are extensive, but quite well defined. They will serve as guidelines for the research to be carried out on Li-air systems. At present, automotive propulsion batteries are just beginning the transition from nickel metal hydride to Li-ion batteries such as IBM ThinkPad R60 Battery, after nearly 35 years of research and development on the latter. The transition to Li-air batteries (if successful) should be viewed in terms of a similar development cycle." Acer UM09E31

35 years? Are your fricken kidding me? Throw that beaker against the wall. Acer 31CR19/65-2

Of course, an unexpected breakthrough or some completely out-of-the-box thinking could turn these lithium-based chemistry studies on their heads. Unfortunately, that's a bet with low probability. Acer 31CR19/652

Nevertheless, that doesn't mean that lithium-ion batteries couldn't be a disruptive technology. Some kind of dynamic charging capability or a change in consumer expectations could rewrite the book on lithium-ion potential. Acer 31CR19/66-2

If for instance, 90 percent of your driving needs require less than 40 miles of range, why can't a plug-in with a minimum of 70 miles of electric power not be feasible? Acer AK.006BT.075

Because if you're gonna pay ,000 for a vehicle you expect far more functionality, right?

But, what if you were only paying ,000 for such a vehicle? Sure it might only be a two-seater. Additionally, such a vehicle might make even the science-fiction looking design of the Toyota Prius seem overly conventional. Acer AK.006BT.080

Regardless, would that really be so bad if such a vehicle were truly cost-effective? So cost-effective in fact that combined with the rental costs for an occasional weekend car for longer trips, your plug-in purchase was still far more cost-effective than any other vehicle?

Maybe. American consumers are a pretty fickle bunch. Acer AS10D battery

Inevitably, lithium-ion batteries are only going to be a disruptive technology if consumers revolutionize their thinking about personal transportation. And, if gas prices keep rising, such out-of-the-box thinking isn't really that hard to imagine.

Will it happen? Probably not, but it could, as could some completely unexpected technological breakthrough. Acer AS10D31

Of course, as hybrid cars have pushed automakers to embrace technologies like start/stop, perhaps lithium-ion can help automakers re-imagine plug-ins in a way never before imagined. Acer AS10D3E

For instance, battery-maker EnerDel's subdivision EnerFuel sees a future where something like the Chevy Volt could significantly reduce its battery size by replacing the gasoline engine with a small fuel cell as range extender with on-board gasoline to hydrogen reformer. Based on such a combination of technologies, EnerFuel envisions powertrain combinations that offer less overall range, such as just 200 miles, but at significantly reduced costs compared to the current Volt's powertrain architecture. Acer AS10D41

200 miles of range with instant fueling capabilities comparable to today's gasoline-powered technologies? Sure it's not perfect for cross country trips, but for everything else it more than works. Even for long distance trips it isn't pushing most consumers that far outside of their box most of the time. Acer AS10D51

Inevitably, lithium-ion batteries by themselves are probably not enough to become a disruptive technology; however, if lithium-ion technologies can provide the impetus to push automakers and consumers outside of their box of conventional thinking and expectations, lithium-ion could still become a disruptive technology.

Right Method to Use Netbook/Laptop Battery Acer AS10D61

Are you using laptop? That you use laptop batteries and how much they know? Long-term use to connect the power of the notebook, how good it save battery? This seems to look not very important issue, actually the life of this notebook has great impact. The following came to know the proper use of laptop batteries it! Acer AS10D71

First, battery program

Most laptops are equipped with automatic functions of reduced frequency, so that maximum benefit is to extend the books of the toshiba portege m400 battery. Many people who use the Celeron may have questions about books, our books do not have this feature, is not naturally less power out? Acer AS10D73 CPU consumption of electricity is only part of fact, the order should be like electricity: LCD> CPU (speed)> Graphics> Wireless LAN> CPU fan. In other words, in addition to CPU, we can start from the other side, the maximum reduction of electricity consumption. Acer AS10D75

In Windows XP Control Panel there is a power management option, the "power scheme", set the LCD screen about 10 minutes in the idle shut down the most reasonable and the hard disk will have to set more appropriate in more than 15 minutes. Instant boot disk does not need a certain power that frequently start and stop on the hard disk damage is considerable. Of course, you can also manually turn off the screen, most of the books are by fn + F3 function key to achieve. Acer BT.00603.111

Set LCD, hard drive shut down time, if you want to further save power, but also running on the system to adjust, it is not a Windows XP can do. Acer BT.00605.065 With Thinkpad, for example, most of the books have built-in battery management software, general books will provide eight screen brightness adjustment, although the state can get the brightest best visual effect, but it is very, very power-hungry, so , edit a document or some other common application to adjust the screen brightness to the lower six or seven best. At the same time, CPU can be set to the best battery performance, CPU fan running status set to "balance" is more reasonable. Acer BT.00603.117 battery

Second, the correct charging method

Many people use the laptop battery, that power began to charge less than 100%, but this will reduce the lithium battery power accelerating the total capacity last long, battery life much shorter time, but life on the greatly shortened . Therefore, the proposal battery will be limited to less than 10% charge from charging again, and be mindful not be set too low, such as the use to only about 3% charge left, which is not enough science. Insufficient power to set the alarm must be generally less than 10% of the alarm as well, less than 3% of the serious alarm means that the battery is insufficient to support the boot into the system the next time. Acer BT.00603.124 Many battery management software is less than 96% of the default start charging, it will damage the battery charge, so be sure to change this setting. In addition, the best off charging the battery so you can play the role of conservation.

Third, discharge necessary? Acer BT.00604.049

If the notebook's battery power for a long time greatly reduced, the depth of discharge can try to "save" it. This is a "dead horse a living horse doctors" approach, not a last resort, better not to do so. Discharge the simplest way is to constantly run the program, less than 3% of electricity to restart the books after running into the BIOS vacant until the automatic sony vgp-bps8 battery power-off date. Then the depth of charge, charging time to reach eight hours, but not more than 12 hours, so you can restore some power to lithium batteries. Acer BT.00605.062
