If the new technology developed by the researchers from the Department of Energy’s Oak Ridge National Laboratory (ORNL) comes into effect, it could make batteries last for as long as 50 years. This feat, that was thought to be impossible, can be achieved using this unconventional battery chemistry.
Every battery has three important components, a cathode, an anode and an ion-conducting electrolyte. Up until now, it was believed that each of these components only have a single role to play in the battery. But the scientists at ORNL have managed to provide dual functions to the electrolyte. So along with conducting ions, it can even double up as a cathode supplement.
The solid electrolyte which can carry out both the aforementioned tasks has been especially developed by the researchers at ORNL. It is basically responsible for providing that extra boost which successfully extends the life of that battery. In a post on the official website of the institute, it was revealed that a demonstration of this technology was also conducted.
Reportedly, the concept was demonstrated using a lithium carbon fluoride battery which is said to have a long shelf life as well as stability. A solid lithium thiophosphate electrolyte was used in it and the results showed an increase of 26 percent in the theoretically maximum power life of the battery. This can chiefly be attributed to the interactions between a cathode and an electrolyte. Also, the lithium fluoride salt that is generated in the process, acts as a catalyst for the electrolyte’s activities.
Researchers at ORNL say that this technology can easily make a battery last for decades. As of now, it is just a concept.
