Lithiation of silicon
Web7 jul. 2015 · However, silicon suffers from a poor cyclability due to the volume fluctuation induced electrode damage during the lithiation/delithiation cycles. To date, many strategies have been attempted to tackle this problem ... as the pre-occupied space by Li can provide adequate volume for the subsequent lithiation/delithiation ... Web15 mei 2024 · Silicon (Si) has the highest known theoretical capacity of 4200 mAh/g, almost ten times that of the currently used graphite anode, and is therefore being considered as the most promising anode material for high-energy-density lithium ion batteries (LIBs) [1,2].Unfortunately, Si suffers from as high as 300% volume change upon full …

WebSynchrotron X-ray Diffraction has been used to make an operando 2D map of the cathode and anode lithiation in the pouch cell, as well as to map the volume expansion across the cell. This approach has revealed that degradation entails significant inhomogeneities across both electrodes, linked to the inhomogeneous volume expansion of the Si-Gr anodes.", The lattice distance between silicon atoms multiplies as it accommodates lithium ions (lithiation), reaching 320% of the original volume. The expansion causes large anisotropic stresses to occur within the electrode material, fracturing and crumbling the silicon material and detachment from the current collector. Prototypical lithium-silicon batteries lose most of their capacity in as few as 10 charge-discharge cycles. A solution to the capacity and stability issues posed by the significa…
WebHere, first-principles computations of lithiation in silicon electrodes are reviewed. The review focuses on three aspects: the various properties of bulk Li-Si compounds with different Li concentrations, the electronic structure of Si nanowires and Li insertion behavior in Si nanowires, and the dynamic lithiation process at the Li/Si interface.
