New tech could extend EV batteries’ lifespan: Researchers at Pohang University of Science & Technology have developed a new battery technology that could significantly extend the lifespan of EV batteries, allowing EVs to drive for up to 1 mn km, The Independent reported on Friday. The technology addresses the degradation of lithium secondary batteries over time and focuses on improving the nickel cathode materials used in these batteries, which traditionally degrade due to the breakdown of tiny crystals during charge and discharge cycles, the news outlet explains.

How does it work? The approach involves producing the cathode material as a single large particle or crystal, which is less prone to degradation. The researchers were able to identify an optimal temperature for creating those high-quality single-crystal materials which make the nickel cathode material more durable. This process — called densification — makes the grains inside the material increase in size by filling in any empty spaces, resulting in the formation of extremely hard crystals that do not degrade easily.
