New technology for lithium-ion batteries recharge in ten minutes is possible




Scientists have succeeded in a new design for small lithium-ion batteries to develop recharge in ten minutes. They particularly by making use of a cluster of carbon nanowires with silicon coating for the anode.

The scientists used a new architecture of three-dimensional cone-shaped clusters of carbon nanowires treated by CVD and ICP, and were fitted with silicon. Rapid charging is thereby made possible by the seamless connection of the carbon nanowire cones and covered with graphene part of the anode. The cones thus form channels for a faster connection between the anode and the cathode.

Charging can be sixteen times faster than with traditional anodes which are based on graphite, claim scientists from the Riverside Bourns College of Engineering at the University of California. In addition, the efficiency would not or hardly decrease, even after a large number of charge and discharge cycles.

The use of silicon for the anode, the charge capacity compared to graphite variants and the tenfold increase of the cell capacity is also brings forty percent lighter and smaller battery’s fingertips. The researchers describe their findings in an article that appeared in the scientific journal Nano Micro Small.
