A team of engineers at Pennsylvania State University promises to end the term anxiety, or Range Anxiety, of the English term. The behavior is known among electric car owners as the fear that the vehicle run out of energy before reaching your destination.

The solution can be in use of batteries made of iron phosphate. Chao-Yang Wang, director of the university's electrochemical engine center, revealed that his team of engineers has managed to create a smart battery that could revolutionize the electric car industry in the future.


According to Wang, in addition to being innovative, the solution found by the researchers is still inexpensive and has costs comparable to the production of a traditional combustion engine.

Iron phosphate batteries for electric cars

Iron phosphate batteries offer a range of more than 400 km and have enough life to cover more than 3.200 km. Unlike traditional batteries, the component can still be recharged in just 10 minutes. This is another factor that, according to Wang, can put an end to the fear of running out of energy before reaching a charging station.

The secret to extended autonomy and faster recharging is the ability of the iron phosphate battery to heat and cool automatically. This smart process developed by Wang and his team uses a thin layer of nickel foil to work. One end of the nickel foil is attached to the negative terminal of one of the battery cells, while the other end extends to the outside of the cells.

When electrons start flowing through the battery, it quickly heats the nickel sheets, gradually increasing the component's internal temperature. Upon reaching 60 degrees centigrade, the iron phosphate battery is ready to be used or recharged.

According to Wang, this intelligent process also allows low-cost materials to be used in the cathode - electrode from which the current leaves a polarized device - and in the anode - electrode through which the positive electrical charge flows into a polarized device. The cathode is made of lithium and iron phosphate, eliminating the use of more expensive materials such as cobalt. The anode, on the other hand, is composed of a large graphite particle.

Wang concludes by saying that he has finally found a battery capable of benefiting the average consumer in the electric car market. "This is how we are going to change the environment, and not just contribute to luxury vehicles," he said.

Finally, the engineer says that a set of iron phosphate batteries produces enough power for an electric vehicle to go from zero to 100 km / h in just three seconds. Something comparable to a sports vehicle from famous automakers, such as the German Porsche.
