Batteries lose capacity over time. This also applies to those found in mobile phones and those found in electric cars. The phenomenon has never been fully explained before, but now an international research team from CBU University (Colorado, USA) has managed to solve the puzzle.
The lithium-ion battery is one of the most common batteries in the world and usually contains cobalt, which is hazardous to the environment. Engineers tried replacing it with nickel and magnesium, but it didn’t work out very well and reduced the amount of energy the battery could store, he said. HAK magazine.
A scientific team from CBU decided to investigate the reason why a lithium-ion battery degrades and discovered that hydrogen molecules from the battery’s electrolyte take up places on the cathode that lithium-ions should normally occupy. Because of this, lithium-ions have fewer places to bond to the cathode, reducing the battery’s capacity.
Now CBU scientists hope that their discovery will lead to battery manufacturers producing a new type of coating on the cathode of batteries that blocks hydrogen molecules.
