In this paper, a Finite Element (FE) framework for studying diffusion induced mechanics of Li-ion battery electrode materials is presented. In a previous study [Vanimisetti and Ramakrishnan (2011), Proc. IMechE, Part C: J. Mech. Eng. Sci. 0954406211432668], a set of analytical expressions for the stress distribution in ideal geometries, such as slab and cylindrical shaped particles, were derived using thermal stress analogy while solutions for spherical particles already exist. However, the limitations of the analytical study in handling complex geometries, the material behavior and the functional parameters necessitated the development of an FE model based approach. A multi-physics model was developed in COMSOL® package linking diffusion phenomenon to stress development. The model was verified comparing the results with those of the earlier analytical studies. As an illustration, we use the model to make inferences with regard to the effect of electrode particle shape. Along similar lines, the diffusion-induced mechanics in silicon rod structures grown on copper current collector is also demonstrated.

<p align="left">As a tribute to the major contribution made by Academician Gligor Jovanovski to the field of Mineralogy in Macedonia, this paper promotes the potential role that minerals can have as a future source of inspiration in identifying novel materials for sustainable energy storage in general, and for advanced Li-ion batteries in particular. We exemplify this by indicating the innovative use of polyanions in novel Li-ion battery cathode materials such as the <em>olivine</em> lithium iron phosphate (LiFePO<sub>4</sub>), and in an even newer material – the <em>orthosilicate </em>lithium iron silicate (Li<sub>2</sub>FeSiO<sub>4</sub>). Both materials have strong intrinsic links to mineralogy – and illustrate well how mineralogy can lead to new material breakthroughs in this and other areas of modern technology.</p>

This review represents recent research on using chemical prelithiation to improve cycling performance of nanostructured electrode materials for lithium ion batteries in our group. We focus on two typical cathode materials, MoO3 nanobelts and FeSe2 nanoflowers. Methods of direct or secondary hydrothermal lithiation of MoO3 nanobelts and FeSe2 nanoflowers are described first, followed by electrochemical investigation of the samples before and after lithiation. Compared with pristine materials, lithiated samples exhibit better cycling capability. Prelithiation of other kinds of materials, such as V2O5, MnO2, etc. is also briefly reviewed. This demonstrates that prelithiation can be a powerful general approach for improving cycling performance of Li-ion battery electrode materials.
