Recently, in the 2014 Atlanta Advanced Automotive Battery Conference (Advanced Automotive Battery Conference) , the United States and Israel Phinergy Alcoa Aluminum Company Phinergy - further development of the problem of air batteries signed a joint development agreement.
　Phinergy aluminum - air batteries can effectively improve the mileage of electric vehicles , including the joint development agreement in the specific business scope includes the field of new materials, new technology and components , etc. The purpose of this joint development is to promote aluminum as soon as possible - air batteries the commercialization process .
　Alcoa Inc. (Alcoa) is the world 's leading alumina, primary aluminum and aluminum products manufacturer . Israel Phinergy company as a metal - air battery research and development leader , whose main products include aluminum - zinc air batteries as well - air batteries.
　Aluminum - air batteries obvious advantages and disadvantages
　Aluminum - air battery as a non- rechargeable batteries , which had already come out as early as the 1960s , it has a very high energy density. Aluminum - air batteries by the catalytic air cathode , electrolyte and aluminum anodes , whose theoretical energy ratio of 8.1 kWh / kg , second only to lithium - air batteries 13.0 kWh / kg.
　However, since the aluminum - air battery anode during discharge etching produces hydrogen , which not only lead to excessive consumption of the anode material , but also increase the electrical losses inside the battery . This has seriously hampered the aluminum - air battery commercialization process . The conventional method for solving the above problem is specific to the main alloying elements in high-purity aluminum metal doping to improve the corrosion resistance of anodized aluminum , or adding a corrosion inhibitor in the electrolyte.
　Ph.D. , executive vice president , chief technology officer of Alcoa and Raymond Kilmer said: "At present , the automotive industry is looking for a new alternative to traditional gasoline zero-emission clean energy , while Phinergy aluminum - air batteries can guarantee a good cruising mileage car , so the Phinergy aluminum - air battery is the most likely alternative to traditional gasoline achieve zero emissions of new non-polluting energy . "
　Phinergy said , it has developed a proprietary anode aluminum production process which can improve the energy utilization of aluminum and reduces unnecessary energy consumption of chemical reactions . Phinergy company also said it has developed an advanced battery management system , its purpose is to increase the energy of the battery use .
　Against corrosion, a substantial increase in the electric car mileage
　Phinergy company said its Phinergy aluminum - air cell air cathode equipped with special silver -based catalyst , which uses a unique and innovative structure that allows oxygen passed , and carbon dioxide can be blocked out. This innovative structure , Phinergy aluminum - air cell air cathode electrode can effectively avoid the problem of carbonization , its working life and therefore can reach thousands of hours .
　Phinergy aluminum - air batteries work, its internal aluminum into aluminum hydroxide reaction . The aluminum hydroxide can be processed through the aluminum for recycling, so that we can achieve sustainable utilization.
　According Phinergy company, its Phinergy aluminum - air batteries CCP contains 50 aluminum, of which the energy generated by each piece of aluminum can be individually driven cars with 20 miles , so the whole Phinergy aluminum - air battery life can reach 1000 miles mileage (about combined 1600 kilometers) . In addition , Phinergy aluminum - air batteries have also been successfully applied to integrate electric vehicles on display .
　In addition to applications in the electric vehicle industry and foreign , Phinergy also said its metal - air batteries can also be applied to stationary energy applications , such as hospitals , data centers with commercial emergency generator , a generator and a universal mobile homes, unmanned vehicles and other defense applications and so on. Meanwhile, the Phinergy aluminum - air batteries also have sustainable , high energy density and other characteristics, it can also serve as the first energy use. Thus, according to the agreement Phinergy and Alcoa company is cooperating to develop more application technology.
　Alcoa Division, which participated in the project on the outskirts of St. Petersburg in the Alcoa Technical Center , the technology center is the world's largest light metals research institutions.
