“Top Ten Science News” Award is part of “Global Science” magazine ( “Scientific American” magazine Chinese version) which is a major highlight of each year, this year is the fourth selection from 2006.2009 annual “top ten science stories,” named “Global Science” magazine and co-creation of Sina online selection stages. The following is candidates batterey,Canon BP-711and others News:
In March 2009, the U.S. Massachusetts Institute of Technology scientist Cedal and his colleagues developed a revolutionary mobile phone Canon NB- batteries, and compared to the ordinary battery which recharge time takes a few hours, this battery can be just 10 seconds to complete charging and a new battery , Casio NP-20 charging speed is 100 times than traditional batteries, it can be used in mobile phones, laptop computers, iPod, digital cameras and cameras in two to three years .In addition, the same technology can significantly reduce the electric car charging time forCanon BP-522battery , it can fill the car with the traditional time for comparable, thus wiping out the biggest obstacle what green cars must face
Battery,Canon BP-535 charging or discharging is slow , because it take some time for the lithium-ion flow from one electrode to another electrode.
The researchers make structure of the traditional electrode surface which is made of lithium iron phosphate improved, so that lithium-ion release and inhalation speed greatly is improved for 100 times than the original Canon BP-608 battery .making use of this new battery prototype only takes 10-20 seconds to complete the process of charging or discharging. In contrast, a considerable volume of ordinary batteries, Canon BP-617 need charging 6 minutes to complete.
And other battery materials are different, the new material does not repeat the charge and discharge with aging. Scientists said that the Canon BP-battery can be charged faster to use two consecutive years or 3 years.In addition, this technology can also be used to develop a new generation of smaller, lighter Canon LP-E5 batteries, so that the tall, mobile phones and laptop battery, Canon BP-945 is only the size of a credit card.
