The research team from The University of Texas at Austin, Northeastern University, Stanford University and Argonne National Laboratory found that every cycle of charge and discharge causes batteries to expand and contract, similar to human breathing. This action causes battery components to warp just a tiny amount, putting strain on the battery and weakening it over time. This phenomenon, known as “chemomechanical degradation,” leads to reduced performance and lifespan.

Wasn't this already widely known? I knew about this phenomenon since long ago, it doesn't feel like new discovery

Known in the industry for decades, not independently researched bcs it doesn't matter if you aren't manufacturing it? Maybe they documented it a bit more in the parts that were irrelevant to the industry? Idk, I'm guessing.
