Manipulation of lithium dendrites based on electric field relaxation enabling safe and long-life lithium-ion batteries.

ABSTRACT: Lithium dendrites, with their high reactivity, pose a critical challenge to the safety and longevity of lithium-based batteries. Effective regulation strategies are crucial for mitigating battery degradation and enhancing reliability. Conventional approaches, such as relaxation following lithium plating or regulated discharging, often fail to simultaneously address the formation of solid electrolyte interface and isolated lithium. Here, we demonstrate that rational utilization of electric field relaxation following dendrite growth can reduce defective solid electrolyte interface and isolated lithium by balancing solid electrolyte interface growth and dendrite morphology smoothing near the relaxation time constant. Building upon the mechanism, we propose a short-term relaxation method to ma
