Anode-free lithium metal batteries are the most promising candidate to outperform lithium metal batteries due to higher energy density and reduced safety hazards with the absence of metallic lithium anode during initial cell fabrication. In general, researchers report capacity retention, reversible capacity, or rate capability of the cells to study the electrochemical performance of anode-free lithium metal batteries. However, evaluating the behavior of batteries from limited aspects may easily overlook other information hidden deep inside the meretricious results or even lead to misguided data interpretation. In this work, we present an integrated protocol combining different types of cell configuration to determine various sources of irreversible coulombic efficiency in anode-free lithium metal cells. The decrypted information from the protocol provides an insightful understanding of the behaviors of LMBs and AFLMBs, which promotes their development for practical applications.
无阳极锂金属电池是最有希望超越锂金属电池的候选者，因为其具有更高的能量密度，并且在初始电池制造过程中由于没有金属锂阳极而降低了安全风险。一般来说，研究人员通过报告电池的容量保持率、可逆容量或倍率性能来研究无阳极锂金属电池的电化学性能。然而，从有限的方面评估电池的行为可能很容易忽略隐藏在虚假结果深处的其他信息，甚至导致错误的数据解读。在这项工作中，我们提出了一种综合方案，结合不同类型的电池配置，以确定无阳极锂金属电池中不可逆库仑效率的各种来源。从该方案中解密的信息提供了对锂金属电池和无阳极锂金属电池行为的深刻理解，这促进了它们在实际应用中的发展。
