The Nanowires offer advantages of a great surface-volume ratio, efficient electronic ways of conduction and easy relaxation of the tension. We will explore these advantages in a nanowire battery architecture for high-energy, high-power batteries for electric vehicles. In the last two months since it was funded by the GCEP, we have advanced the synthesis of nanowires and are testing their performance as battery electrodes.
The rechargeable battery is a promising technology for the reversible storage of electricity in electric vehicles. Current electric vehicles are powered by lead, NiCd or nickel hydride batteries, which are limited by their energy density and calendar life. Existing lithium-ion battery technology, which uses LiCoO2 as cathode, lithium graphite as anode and organic solvent of LiPF6 as electrolyte, has been the most important source of energy for portable electronics. However, the high cost and low production volume due to the Co's shortage are the biggest obstacles to its broad applications in light vehicles. The solution is to lower cost and maximize performance. The electrolyte in general does not limit Li battery technology.
