The need for high energy batteries for traction applications and electrochemical characterization of the lithium-silicon system (PPT)

摘要

A brief look at battery characteristics of (i) the recent past, (ii) current products, and (iii) future products I won't cover future products and trends, as I overviewed these at the Monday afternoon panel session ("KEY DRIVERS OF CHANGE IN PERSONAL TRANSPORTATION: ELECTRIFICATION EMPHASIS") Technical content: recap of three related recent publications 1. A method to model electrodes involving multiple reactions and species: application to thin-film electrodes of Li-Si 2. Thermodynamics, stress, and Stefan-Maxwell diffusion in solids: application to small-strain materials used in commercial lithium-ion batteries 3. Swelling and elastic deformation of Li-Si electrode materials
