Researchers have developed a new electric vehicle (EV) battery that has a range of 250 miles and can be charged in just 10 minutes.
According to a report, which was published today (January 19) in the journal Nature Energy the key to long-life and rapid recharging is the battery’s ability to quickly heat up to 140 degrees Fahrenheit, and then cool down when the battery is not working.
In light of this, researchers at Penn State University have developed a new lithium-ion phosphate battery which uses a self-heating approach.
The battery uses a thin nickel foil with one end attached to the negative terminal and the other extending outside the cell to create a third terminal. Once the electrons flow, it rapidly heats up the nickel foil through resistance heating and warms the inside of the battery.
The researchers have said that by using this self-heating method, they can use low-cost materials for the battery’s cathode and anode and a safe, low-voltage electrolyte.
According to the researchers, an electric vehicle with this battery could go from zero to 60 miles per hour in 3 seconds and would be good for up to 2 million miles in its lifetime.
Chao-Yang Wang, chair of mechanical engineering and director of the Electrochemical Engine Center at Penn State University, said: ‘We have developed a pretty clever battery for mass-market electric vehicles with cost parity with combustion engine vehicles.
‘The very fast charge allows us to downsize the battery without incurring range anxiety.
‘This battery also has reduced weight, volume and cost. I am very happy that we finally found a battery that will benefit the mainstream consumer mass market.
‘This is how we are going to change the environment and not contribute to just luxury cars. Let everyone afford electric vehicles.’
