    Low-concentration Electrolytes for Anode-free Lithium Metal Batteries

## Description

- description: Anode-free lithium metal batteries (AFLMBs) have attracted great attention
    owing to their higher energy density compared to conventional lithium metal batteries.
    Unfortunately, AFLMBs still suffer from poor Coulombic efficiency (CE) due to
    severe dendrite growth and the unstable solid–electrolyte interface (SEI) at the
    anode. Therefore, we explored the effect of concentration and LiNO3 additive on
    the SEI layer and on Li plating/stripping efficiency using a low-concentration
    tetraethylene glycol dimethyl ether (TEGDME)-based electrolyte in an AFLMB anode
    half-cell configuration. It was found that the formation of protective Li2O-based
    SEI layers when blocking the oxidative subsequent SEI formation (called ‘‘OSS’’)
    above 2.2 V vs. Li/Li+ improved Li plating/stripping stability, while the LiNO3
    additive suppressed the oxidation of Li2O into Li2O2 and sustained the existence
    of Li2O without blocking OSS, therefore improving CE performance. Although increasing
    the concentration (from 0.4 M to 2.0 M) did not have a major effect, the 2.0 M
    electrolyte with LiNO3 additive shifted the dominant SEI species from Li2O to
    LiF, further enhancing CE performance.
