Researchers at the National Institute of Technology Rourkela (NIT Rourkela) have created a new type of material for the batteries that power our smartphones, laptops, and electric cars. This new material replaces cobalt, a metal that’s expensive and hard to find, with cheaper and more environmentally friendly options like magnesium and nickel.
Dr. Partha Saha, who led the team of researchers, said their new battery materials allow for better movement of lithium, which helps the battery work better overall. This means the batteries will last longer, hold more energy, and stay stable over time. After 100 charge and discharge cycles, their new batteries still kept 74.3% of their energy, which is much better than traditional batteries made with cobalt.
Cobalt has many problems, including its high cost, unreliable supply from countries like Cuba and Madagascar, and serious concerns about how it affects the environment. The team at NIT Rourkela’s innovation could change the future of batteries, making them cleaner and more affordable.
This exciting research was made possible with help from the Department of Science and Technology and involved the Department of Physics and Astronomy at NIT Rourkela. For more details, check their official website
