UT Dallas researchers have identified the cause of LiNiO₂ battery degradation and developed a structural reinforcement method that could enable its commercial use in longer-lasting lithium-ion batteries.

Lithium nickel oxide (LiNiO₂) is a promising material for next-generation lithium-ion batteries with longer lifespans. However, its commercialization has been hindered by degradation after repeated charging cycles.

Researchers at the University of Texas at Dallas have identified the cause of this breakdown and are testing a solution that could overcome a major obstacle to its widespread use. Their findings were recently published din the journal Advanced Energy Materials.
