Their role in Li batteries has been expanded beyond direct Li storage to include catalyzing electrochemical reactions and trapping reaction intermediates. Morphological control has been a critical parameter used to impart nanomaterials with significant versatility to adapt to different Li battery systems.
Conclusive summary and perspective Lithium-ion batteries are considered to remain the battery technology of choice for the near-to mid-term future and it is anticipated that significant to substantial further improvement is possible.
Accurate 3D representations of lithium-ion battery electrodes can help in understanding and ultimately improving battery performance. Here, the authors report a methodology for using deep-learning tools to reliably distinguish the different electrode material phases where standard approaches fail.
The performance of lithium-ion batteries (LIBs) is intimately linked not only to the electrochemical properties of the constituent materials but also to the morphology of these materials 1. The pore structure of LIB electrodes and separators determines the effective transport coefficient for lithium-ions in the electrolyte 2, 3, 4.
Accordingly, the choice of the electrochemically active and inactive materials eventually determines the performance metrics and general properties of the cell, rendering lithium-ion batteries a very versatile technology.
This review aims to cover both advanced electron microscopy imaging techniques and their applications in the characterization of battery materials involving cathode, anode, and separator and solid electrolyte interphase (SEI).
