Scientists have succeeded in a new design for a small lithium-ion batteries to develop that in ten minutes to load. They make use of a cluster koolstofnanodraden with siliciumcoating for the anode.
The scientists used a new architecture of three-dimensional, cone-shaped clusters of koolstofnanodraden treated through cvd and icp, and with silicon. The rapid charging is made possible by the seamless connection of the koolstofnanodraadkegels and a graphene covered part of the anode. The cones to form channels for a faster connection between the anode and the cathode.
The load may be sixteen times as fast as with traditional anodes on graphite based, claim the scientists from the Riverside Bourns College of Engineering at the University of California. In addition, the efficiency does not or hardly decrease, even after a large number of times of charging and discharging.
The use of silicon for the anode, the charge capacity compared to grafietvarianten vertienvoudigen and the increase of the celcapaciteit also brings forty percent lighter and smaller batteries within easy reach. The researchers describe their findings in an article in the scientific journal Nano Micro Small appeared.
