![]() Only the Al/ air EVs can be projected to have a travel range comparable to ICEs. Al/ air EVs life-cycle analysis was conducted and compared to lead/acid and nickel metal hydride (NiMH) EVs. The cost of battery system chosen to evaluate is US 30/kW (present) or US$ 29/kW (projected). The design battery energy density is 1300 Wh/kg (present) or 2000 Wh/kg (projected). The total fuel efficiency during the cycle process in Al/ air electric vehicles (EVs) can be 15% (present stage) or 20% (projected) comparable to that of internal combustion engine vehicles (ICEs) (13%). From our design analysis, it can be seen that the cost of aluminum as an anode can be as low as US 1.1/kg as long as the reaction product is recycled. The Al/ air battery system can generate enough energy and power for driving ranges and acceleration similar to gasoline powered cars. These batteries might be important on a long-term interim basis as the world passes through the transition from gasoline cars to hydrogen fuel cell cars. This study demonstrates the possibility of use of 2N5 grade Al which is cheaper than 4N grade Al as the anode for aluminum-air battery.ĭesign and analysis of aluminum/air battery system for electric vehiclesĪluminum (Al)/ air batteries have the potential to be used to produce power to operate cars and other vehicles. This phenomenon leads to improvement of discharge current density and battery efficiency by reducing self-corrosion reaction. ![]() However, the impurity complex layer of 2N5 grade Al is dissolved with decreasing discharge voltage to 0.8 V. It also depletes discharge current and battery efficiency at 1.0 V which is general operating voltage of aluminum-air battery. The impurity complex layer of 2N5 grade Al declines the battery voltage on standby status. The experimental results show that the new energy aluminum-air battery has good discharge performance, which lays a foundation for its application.Īluminum anode for aluminum-air battery - Part I: Influence of aluminum purityĬho, Young-Joo Park, In-Jun Lee, Hyeok-Jae Kim, Jung-GuĢN5 commercial grade aluminum (99.5% purity) leads to the lower aluminum-air battery performances than 4N high pure grade aluminum (99.99% purity) due to impurities itself and formed impurity complex layer which contained Fe, Si, Cu and others. ![]() A system model is established to analyze the polarization curve, the constant current discharge performance and effect of electrolyte concentration on the performance of monomer. Based on the research on operating principle of aluminum-air battery, a novel aluminum-air battery system was designed composed of aluminum-air cell and the circulation system of electrolyte. Liu, Zu Zhao, Junhong Cai, Yanping Xu, BinĪs a kind of clean energy, the research of aluminum air battery is carried out because aluminum-air battery has advantages of high specific energy, silence and low infrared.
