Fundamental mechanics help increase battery storage capacity and lifespan
Today, I found another nice physics article about a mechanisms that contribute the storage capacity of batteries. We need batteries to run applications like powering electric vehicles, electronic gadgets and are promising candidates for sustainable energy storage. As we know the functionality of battries drops off over time with daily charging. So that, we need to replace the battery or recharge it!
A key factor in battery life reduction is the degradation of a battery’s structural integrity. To discourage structural degradation, a team of researchers from USC Viterbi School of Engineering are hoping to introduce “stretch” into battery materials so they can be cycled repeatedly without structural fatigue. This research was led by Ananya Renuka-Balakrishna, WiSE Gabilan Assistant Professor of Aerospace and Mechanical Engineering, and USC Viterbi Ph.D candidate, Delin Zhang, as well as Brown University researchers from Professor Brian Sheldon’s group. Their work was published in the Journal of Mechanics and Physics of Solids.
