Title: | Non-Uniform Distribution of Current in Plane of Large-Area Lithium Electrodes | Authors: | YARI, Saeed VAN BAEL, Marlies HARDY, An SAFARI, Momo |
Issue Date: | 2022 | Publisher: | Source: | Batteries & Supercaps, (Art N° e202200217) | Status: | Early view | Abstract: | This work asserts that increasing the planar area of a lithium (Li) electrode is a challenge in view of ensuring a uniform plating and stripping and spatial uniformity for the state-of-health over the surface of lithium. A significant in-plane heterogeneity is observed for the symmetric Li cells with the stack area in the range of 24 to 96 cm 2. The cycling of the large-area lithium electrodes is performed inside a dedicated home-made electro-chemical setup capable of incorporating electrodes of different sizes. The cycling data and post-mortem analysis reveal a clear non-uniformity in the distribution of current and aging for the lithium electrodes having a size larger than the coin-cell and relevant to the commercial applications. It is shown that the inhomogeneous aging manifests mainly in the formation of dead Li film with a spatial variation in thickness and impedance over the surface of the Li electrode. | Keywords: | dead lithium;lithium-metal electrode;large area electrodes;non-uniform | Document URI: | http://hdl.handle.net/1942/37792 | e-ISSN: | 2566-6223 | DOI: | 10.1002/batt.202200217 | ISI #: | 000824552300001 | Category: | A1 | Type: | Journal Contribution | Validations: | ecoom 2023 |
