What does this research mean for the field?

In anode-free lithium metal batteries, the charging rate critically governs lithium nucleation and spatial distribution, with a moderate rate of 0.5 C providing an optimal balance between electrical connectivity and structural stability to minimize 'dead lithium' formation. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

Overview

Operando characterization reveals rate-dependent lithium plating and dead lithium formation in anode-free batteries, indicating optimal cycling stability at intermediate charging rates.

Key Points

To quantitatively track depth-resolved lithium plating and stripping behavior across different charging rates in anode-free lithium metal batteries.
Constructed a vacuum-compatible operando neutron depth profiling (NDP) cell based on a liquid-electrolyte anode-free Cu||Li1.2Ni0.13Co0.13Mn0.54O2 full cell.
Tracked the spatial distribution and active lithium loss during plating and stripping under charging rates of 0.2, 0.5, 1, and 2 C.
A 0.2 C rate produced sparse nucleation sites directing lithium growth toward the electrolyte, while higher rates (1 and 2 C) generated loose mossy deposits that lost electrical contact during stripping to form dead lithium.
A 0.5 C rate provided structural stability and preserved electrical connectivity during stripping, yielding the most favorable cycling performance among the tested conditions.
