Numerical and experimental investigation of (de)lithiation-induced strains in bicontinuous silicon-coated nickel inverse opal anodes
A volume expansion of up to ~310% occurs upon the lithiation of silicon in Si-coated nickel inverse opal anodes, which causes (de)lithiation-induced mismatch stresses and strains between the Si and Ni during battery cyclical (dis)charging. These (de)lithiation-induced mismatch strains and stresses are modeled via sequentially coupled diffusionand stress-based finite element (FE) analysis, which...
متن کاملThree-dimensional metal scaffold supported bicontinuous silicon battery anodes.
Silicon-based lithium ion battery anodes are attracting significant attention because of silicon's exceptionally high lithium capacity. However, silicon's large volume change during cycling generally leads to anode pulverization unless the silicon is dispersed throughout a matrix in nanoparticulate form. Because pulverization results in a loss of electric connectivity, the reversible capacity o...
متن کاملUnderstanding Phase Transformation in Crystalline Ge Anodes for Li-Ion Batteries
Lithium-ion batteries using germanium as the anode material are attracting attention because of their high-capacity, higher conductivity, and lithium-ion diffusivity relative to silicon. Despite recent studies on Ge electrode reactions, there is still limited understanding of the reaction mechanisms governing crystalline Ge and the transformations into intermediate amorphous phases that form du...
متن کاملEffects of Silicon and Carbon Composition on Carbon Nanotubes in Lithium-Ion Batteries
Introduction Lithium-ion (Li-ion) batteries are attractive for many applications due to their high energy density and low selfdischarge rate. To further increase the energy and power densities of Li-ion technology, significant activity to increase the capacity of the anode has been conducted. Silicon anodes have the potential to increase the current state-of-art anode (graphite) capacity by nea...
متن کاملPreparation of Ni current collector and MoS2 cathode in three-dimensional Li ion microbattery based on silicon MCP
Three-dimensional Li ion microbatteries are known for their high surface area which leads to high current and capacity compared to traditional planar batteries. This paper describes economical approaches to prepare half 3D microbatteries based on silicon microchannel plates (MCP). The high aspect ratio silicon MCP is formed by electrochemical etching and a nickel layer is coated onto the silico...
