Military aluminum-air chemical battery technology uses electric vehicles

The Israeli company Phinergy and Alcoa have teamed up to showcase an aluminum-air chemical battery, which 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 Canadian International Aluminum Conference held recently; the two companies said that the new technology can be used as an electric vehicle The driving distance extension device is used with a small traditional lithium-ion battery.
One of the current shortcomings of electric vehicles is the anxiety related to driving distance; Ray Kilmer, Chief Technology Officer of Alcoa, said: Our technology breaks through the bottleneck and combines the commonly used lithium-ion battery with when you need to travel more often. The aluminum-air battery used has been combined.

Aluminum-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 demonstration, a vehicle equipped with a battery developed by Phinergy can travel 330 kilometers on a single charge as long as it is charged with water.
Phinergy founder and CEO Aviv Tzidon said that the company’s current aluminum-air battery pack has an energy ratio of 300 Wh/kg; however, he also emphasized that the company’s ultimate goal is to create a 1,000 Wh/kg energy ratio battery. Group, the price will be less than 100 US dollars per kilowatt hour ($100/kWh).
Phinergy said that each aluminum plate of the aluminum-air battery can provide 20 miles of driving distance, and a total of 50 aluminum plates of batteries can provide up to 1,000 miles of driving distance.
If Phinergy’s goal can be achieved, it will be a major technological advancement beyond the current lithium-ion batteries; the typical energy density of lithium-ion batteries on the market (cells) is only 150~240 Wh/kg, and the energy density of battery packs is also Not as good as aluminum-air batteries; and lithium-ion batteries cost 300 to 450 dollars per kilowatt hour.
