Abstract

Li-air battery is considered as a promising alternative in the future to replace the current battery technologies. It can eliminate the common range anxiety in electric vehicles for its compelling high energy density. However the extremely low power density becomes its deadly drawback which makes it unsuitable for automobile application. In this article, we built a dual-battery model with a high power density Li-ion battery and a high energy density Li-air battery to investigate the potential of this hybrid solution and tried to get a reference value about the target for the resistance and power density of Li-air battery in the following years. After tests we’ve got a conclusion that with a total dual-battery weight at 300 kg, an average resistance around 0.015 per cell which correspondingly leads to the power density 65 kW/kg in a pack level could be suggested as a minimal target for Li-air battery. The optimal choice of weight ratiobetween two batteries is essential for thepower design of Li-air battery.
