“…From the mechanical perspective, the following two kinds of composite electrodes were studied, such as composition-gradient electrodes that modify the mechanical properties of active materials [30][31][32] and composite electrode reinforced with additives. 29,[33][34][35] These studies investigated the diffusion-induced stress of composite active plates and bi-layer active plates. However, the stress was analyzed by regarding the bi-layer active plates as singlelayer composite materials using the mechanics of composite material.…”

Experimental studies have demonstrated that lithium battery electrodes with multi-layer active plates exhibit both high volumetric capacity and rate capability. The overall performance of such electrodes is closely related to the mechanical response, which is impacted by Li-ion transport. Herein, detailed descriptions of diffusion and induced stress in silicon-graphene layered composite electrode were theoretically investigated. First, the natural eigenfunction expansion method was used to obtain the exact analytical solutions of Li-ion concentration field in bi-layer active plates under galvanostatic and potentiostatic charging. Then, the biaxial stress expression of composite electrodes was deduced. Moreover, the diffusion contact resistance was explored to describe the resistance effect of interface between different layers for Li-ion diffusion, which is lacking in previous studies. Our findings suggest that the diffusion contact resistance will increase stress in the electrode, and its influence should be minimized as much as possible. Furthermore, material properties, such as the distribution of active materials, have a significant impact on the performance of composite electrodes. In present work, the mechanism of diffusion-induced stress on electrodes with bi-layer active plates was clarified, and it provide a guidance for electrode design from the perspective of mechanics.

“…On the other hand, adding functional fillers to the active layer is also an effective way to enhance the mechanoelectrochemical properties of the multilayer electrodes. The presence of bidimensional transition-metal carbides and/or nitrides (MXenes) [19,20], graphene [21,22], carbon nanotubes [23] and SiC [24] can effectively enhance the mechanical properties of the composite active layer, reduce the lithiation induced stress and improve the mechanoelectrochemical stability of the layered electrodes. Mao et al have demonstrated that adding a small amount of multiwalled carbon nanotubes can not only enhance electrochemical performances, but also mechanical properties of the composite active plates [25,26].…”

The lithiation induced stress in multilayer silicon/graphite-based electrodes for lithium ion batteries is evaluated analytically. Firstly, the silicon/graphite-based composite active layer is reinforced by Ti3C2 MXene, and the effects of Ti3C2 MXene additive on elastic modulus of the active layer are discussed based on the Halpin-Tsai empirical equation. Secondly, biaxial stresses in both bilayer and symmetric trilayer silicon/graphite-based electrodes are estimated by a mechano-electrochemical model, which is derived by imitating thermal expansion stress in layered structural components. And the effects of Ti3C2 MXene’s parameters, including additive amount, number of layers and length-width ratio, on the stress in multilayer silicon/graphite-based electrodes are also be discussed in detail. Finally, based on the numerical analysis, some design strategies for Ti3C2 MXene reinforced composite active layer are proposed from mechanical views.
