IEEE to Redefine Cell Phone Battery Standard
Today the IEEE (Institute of Electrical and Electronics Engineers) stated that it plans to revise the existing standard that governs the design and manufacture of rechargeable lithium ion and lithium ion polymer batteries. The current standard (IEEE Std 1725) has been in place since 2006, and the IEEE feel that it is now outdated due to the increasing adoption of connected devices. The IEEE said in a prepared statement, "In addition to setting criteria for qualification, quality, and reliability of rechargeable lithium ion and lithium ion polymer batteries, the standard also addresses battery pack electrical and mechanical construction, packaging technologies, and pack and cell level charge and discharge controls." The IEEE has established the Cell Phone Battery Working Group to tackle the revisions. The group will hold its first meeting in February 2010.
AT&T's Latest GoPhone Runs On AA Batteries
AT&T today announced the SpareOne Emergency Phone, a simple handset meant purely to serve as a backup phone for critical situations. The SpareOne runs on AA batteries, rather than a rechargeable lithium-polymer power cell.
Scientists Cook Up Quick-Charging Aluminum Battery
Aluminum-ion batteries may replace lithium-ion batteries in mobile devices thanks to a breakthrough made by U.S. researchers.
Samsung Researchers Make Battery Breakthrough
A research team working at Samsung has discovered a new way to make lithium-ion batteries that could double the available battery life in devices such as smartphones. The method involves covering silicon nanoparticles with graphene, which prevents the formation of silicon carbide.
Sony Hoping to Boost Battery Capacity By 40%
Sony is looking at sulfur to help improve the performance of rechargeable batteries. Sony says using sulfur as an electrode material can increase the energy density from today's limit of 700Wh/L to 1,000Wh/L.
Yeah yeah yeah...
But yeah, both cell phone, and especially laptop batteries have ...
15 minutes charger?
y cant they charge cellphone battery in 15 minutes!
That was a lot of mumbo jumbo...
