Achieving Stable Lithium Anodes through Leveraging Inevitable Stress Variations via Adaptive Piezoelectric Effect

Advanced Materials, Journal Year: 2024, Volume and Issue: 36(19)

Published: Feb. 7, 2024

Abstract Unleashing the potential of lithium‐metal anodes in practical applications is hindered by inherent stress‐related challenges arising from their limitless volume expansion, leading to mechanical failures such as electrode cracking, solid electrolyte interphase damage, and dendritic growth. Despite various protective strategies “combat” stress anodes, they fail address intrinsic issue fundamentally. Here, a unique strategy proposed that leverages generated during battery cycling via piezoelectric effect, transforming adaptive built‐in electric field accelerate lithium‐ion migration, homogenize lithium deposition, alleviate concentration. The mechanism effect modulating electro‐chemomechanical evolution further validated decoupled through finite element method simulations. Inspired this strategy, high sensitivity, fast responsive, strength adaptability polymer used demonstrate feasibility corresponding protected anode shows stability over 6000 h under current density 10 mA cm −2 extending life variety coin pouch cell systems. This work effectively tackles issues decoupling also contributes developing more stable for future research.
