New Electric Vehicle Battery Supports Rapid Self-Heating

Besides fueling the engines of automotive vehicles, probably the second most important job of the source of energy, be it fossil fuel or battery driven, is to heat or cool the cabin and make it almost immune to the outside atmosphere. While the automotive industry is booming on the back of growing demand for electric vehicles as a result of escalating air pollution levels, the restraint of it failing to cool or heat the cabin as rapidly as the fossil fuel driven one did, is hindering the ubiquity of EVs.

However, a team of engineers from the Penn State may have paved a way to overcome this challenge. They have developed a battery that is capable of self-heating, which means rapid charging despite outside chill. In the U.S., so far, electric vehicles have mostly remain confined within the western cost as the weather is mostly idea for them. However, consumer in the colder regions in the Eastern parts as well as in Canada are refraining from the concept of EVs because of heating restraints.

This new battery uses thin nickel foil in which one of the ends of fixed to the negative terminal while the other extends outside to the cell in order to create a third terminal. With a temperature sensor, electrons are made to flow through the nickel foils and once the battery has an internal temperature around the room temperature, it turns on and electricity starts to flow.

The researchers have notified that their self-heating batteries can withstand 4,500 cycles of 15 mins, which leaders to gain of charge at 32 degrees F while only 20% of the total capacity is lost.
