Not being able to recharge an electric vehicle when the power runs out is a major cause for concern for electric car owners, especially in developing countries, where charging stations are not readily available.
Another thing that is of concern to electric car owners is the “Range” the range or distance that their car can travel is major source of anxiety.
It is however interesting to know that all this forms of anxiety might be a thing of the past, as some Penn State engineers who are developing lithium iron phosphate batteries that have a range of 250 miles with the ability to charge in 10 minutes.
Now that is amazing! isn’t it?
This research was supported by the U.S. Department of Energy’s Office of Energy Efficiency and Renewable Energy and the William E Diefenderfer Endowment.
we developed a pretty clever battery for mass-market electric vehicles with cost parity with combustion vehicles. There is no more range anxiety and this battery is affordable.”Chao-Yang Wang, William E. Diefenderfer Chair of mechanical engineering, professor of chemical engineering and professor of materials science and engineering, and director of the Electrochemical Engine Center at Penn State
This group of researchers also say that the battery should be good for 2 million miles in the future.
According to report in the Nature Energy that the car holds its fast charging a long distance travel, due to its ability to quickly heat up to 140 degrees Fahrenheit, for both charge and discharge, and then quickly cool down when the battery isn’t working.
The battery uses a self-heating mechanism previously developed in Wang’s center.
The self-heating 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 electrons flow it rapidly heats up the nickel foil through resistance heating and warm the inside of the battery.
Once the battery’s internal temperature is 140 degrees F, the switch opens and the battery is ready for rapid charge or discharge.
The very fast charge allows us to downsize the battery without incurring range anxiety, this is how we are going to change the environment and not contribute to just the luxury cars, let everyone afford electric vehicles.said Wang
Because of the self-heating, the researchers said they do not have to worry about uneven deposition of lithium on the anode, which can cause lithium spikes that are dangerous.
“This battery has reduced weight, volume, and cost,” said Wang. “I am very happy that we finally found a battery that will benefit the mainstream consumer mass market.”
According to Wang, these smaller batteries can produce a large amount of power upon heating — 40-kilowatt hours and 300 kilowatts of power. An electric vehicle with this battery could go from zero to 60 miles per hour in 3 seconds and would drive like a Porsche, he said
