Military Aluminum Air Chemistry Battery Technology Using Electric Vehicles

Israeli company Phinergy, in partnership with Alcoa, demonstrated an aluminum-air chemical battery that claims to allow electric vehicles to travel up to 1,000 miles (about 1,600 kilometers) per charge. ).

Phinergy and Alcoa demonstrated the latest electric vehicle battery technology on a track in Montreal during the recent Canadian International Aluminum Conference; the two companies stated that the new technology can be used as an electric vehicle. Distance extension device for small, traditional lithium-ion batteries.

One of the shortcomings of current electric vehicles is their anxiety related to driving distance. Ray Kilmer, chief technology officer of Alcoa, said: Our technology has broken through the bottleneck, and it will be able to use the commonly used lithium-ion battery and when you need more frequent driving distances. The use of aluminum air battery made a perfect combination.

Phinergy and Alcoa demonstrate aluminum air electric vehicle battery technology for 1,000 miles on a single charge

Al-air chemical battery technology has existed for decades and is mostly used in the military field; this technology combines aluminum with outside air and water and is known to have the potential to provide high energy density. In the live show, a vehicle equipped with a battery developed by Phinergy can use a water charge to run 330 kilometers after a single charge.

Phinergy founder and CEO Aviv Tzidon said that the company's current development of aluminum air battery power ratio is 300 Wh/kg grade; However, he also stressed that the company's ultimate goal is to create 1,000 Wh/kg energy ratio of the battery In the group, the price will be less than $100 per kWh ($100/kWh).

Phinergy said that each sheet of aluminum air battery can provide a distance of 20 miles, and a total of 50 aluminum batteries can provide up to 1,000 miles of travel distance.

If the goal of Phinergy can be achieved, it will be a major technological advancement over current lithium-ion batteries; currently the typical lithium-ion battery energy density (cell) is only 150~240 Wh/kg, and the energy density of the battery pack is also Not as good as aluminum air batteries; lithium-ion batteries cost 300 to 450 US dollars per kilowatt-hour.
