Delithiated state
WebFurthermore, as the novel points of our characterization, we find that (i) the LiCoO 2 grains are in a highly delithiated state after high voltage cycling, causing poor thermal stability; (ii) the stripe-shaped O1 phase is verified in the grain bulk, demonstrating irreversible structural changes upon high voltage cycling; and (iii) the surface ... WebSep 23, 2024 · The lower porosity at the delithiated state compared to the pristine 40% is expected, as some Li + remains in the anode . Despite the relatively large thickness and porosity changes, similar morphologies and thicknesses were observed after multiple cycles (fig. S11). This suggests that the mechanical properties of the Li-Si and SSE have a ...
