Lithium Ion Batteries Become Safe – Add Water and Lose Oxygen

clock August 20, 2010 02:50 by author Susan

Water Battery Lithium Ion AqueousA low cost and safe alternative has been discovered by scientists by adding water to lithium ion batteries. Aqueous lithium ion batteries are inexpensive to manufacture and less dangerous when compared to standard lithium ion batteries. By eliminating oxygen in the lithium-sulfate and water electrolyte solution, the batteries’ capacity has increased, but for small capacities.

The aqueous lithium ion battery can only retain 50% of its charge after 100 charge / discharge cycles, which isn’t acceptable with laptops, digital cameras and other electronic devices. By leaving the pH alone, removing as much oxygen as possible from the battery, and using carbon coated electrodes the batteries’ capacity retention increased to 90% after over 1000 cycles.  The only problem is the aqueous lithium ion battery provided power that lasted 10 minutes, whereas the same type of lithium ion battery lasted 8 hours.

The Aqueous lithium ion battery may not be the right solution for laptops, but might come in handy for devices with short term use, utilizing solar panels and other forms of recharging.

Safer lithium ion batteries: add water, lose the oxygen.

Battery Recalls and Battery Replacements for iPod Nano and BlackBerry

clock August 17, 2010 02:23 by author Ty

Battery recalls and battery replacements for two manufacturers, Apple and Asurion, are replacing and recalling products back this month for battery overheating problems.

Apple’s Japan unit is offering free replacements with the first-gen iPod Nano devices due to overheating batteries that can lead to minor burns for customers. There have been at least 27 cases reported of overheating incidents with 6 fires that left burns on 4 people.  Many of these defective models were sold between September 2005 and December 2006. Apple has sold around 1.8 million units of the first-generation iPod Nano in Japan since September 2005.

Visit Apple’s support page for the iPod Nano battery.

Asurion is recalling counterfeit BlackBerry branded batteries because the batteries can overheat and pose as a fire hazard.  There have been two reports of the BlackBerry®-branded batteries burning a consumer’s finger and also property damage to a sofa and a car seat.  The cell phone batteries were used across virtually all cell phone models of refurbished BlackBerry devices distributed by Asurion prior to November 1, 2009. It is recommended that these batteries stop being used and get replaced for free with upgraded batteries.

Aftermarket BlackBerry cell phone batteries are available to replace your worn out OEM BlackBerry batteries.

Call2Recycle Recycle 1 Million Pounds of Batteries

clock July 27, 2010 20:02 by author Ty

On July 21st, Call2Recycle launched a campaign to recycle 1 million pounds of batteries by October 1st, 2010.

Call2Recycle has over 30,000 public drop-off locations for recycling used batteries and cell phones. According to the U.S. EPA, there are approximately 350 million rechargeable batteries purchased each year. Rechargeable batteries have a higher contamination level vs. disposable batteries and need to be recycled to prevent contamination threats. Since 1996, Call2Recycle has recycled over 55 million pounds of rechargeable batteries since the recycling program has launched in 1996.

Carl Smith, president and CEO of Call2Recycle says, "Millions of batteries are not recycled, primarily because people don’t know that they can be recycled or where to take them for recycling. Our goal with the MyCall2Recycle campaign is to collect 1 million pounds of batteries between now and October 1, by making everyone in the U.S. and Canada aware of the free battery recycling locations in their area; and educating businesses on the advantages of becoming a free battery collection spot.”

Let your family and friends know to recycle their used batteries so Call2Recycle can reach the 1 million pounds of recycling batteries goal. Find a cell phone and battery recycling center near you!

Battery Powered Clock Designs

clock June 29, 2010 19:16 by author Ty

If you're looking for a new clock, there are some interesting clock designs out there that will most likely strike up as a conversation piece. The first one up is a clock that uses it's batteries as the small hourly hand and big minute hand. It's not your typical clock that's digital with the batteries inside. These batteries will be shown on the front of the clock and not hidden in the back.

 

Another interesting design is a clock that uses a spiral hand to mark the hours across popular world locations.

 


We haven't seen these clocks for sale anywhere, but they would make a great gift for someone to stand out among the rest.

Potato Battery

clock June 21, 2010 20:25 by author Ty

Potatoes can be used as a solid organic electric battery and utilized in countries where electrical infrastructure is not yet established. Boiling the potato increases electrical power by 10 times and using zinc and copper electrodes on a treated potato will produce power 50 fold cheaper than 1.5 Volt D cell batteries. This is an incredibly efficient way of creating green power at a low cost, which can be grown in your backyard. There is one downside, the zinc and copper rods will corrode away and need to be replaced. The power created from the potatoes can be used by low powered devices, such as LED lights, communication devices, and small radios.
