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.
Phinergy and Alcoa demonstrate aluminum-air electric vehicle battery technology that can travel 1,000 miles on a single charge
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.
