## Description

- description: Recent studies have highlighted the impressive performance of lithium
    metal batteries (LMBs), showcasing cell-level energy densities surpassing 350
    Wh kg–1. However, the intricate mechanisms leading to cell degradation in these
    batteries remain elusive, impeding their widespread utilization as energy storage
    devices. Specifically, the influence of the discharge rate on the deterioration
    of lithium metal electrodes remains poorly understood. In this study, pouch-type
    Li|NMC811 cells were fabricated employing a lean electrolyte, and a comprehensive
    exploration was conducted into the effects of the discharge rate on the battery
    performance. Intriguingly, our findings illustrate a positive correlation between
    the increase in discharge rate within the range of 0.4–1.6 mA cm–2 and an improvement
    in the cycle life of LMBs. In-depth analyses indicate that increasing the discharge
    current density to 1.6 mA cm–2 effectively suppresses irreversible volume expansion
    in lithium metal electrodes. Consequently, this suppression in volume expansion
    is identified as a significant factor contributing to the enhanced cycle life
    at increased discharge rates. Conversely, when the discharge rate surpasses 1.6
    mA cm–2, a detrimental impact on the cycle life is observed due to kinetic limitations
    experienced by the NMC electrode. These findings elucidate the operational principles
    governing LMBs, offering insights into achieving both high-power density and extended
    cycle life.
