Li Batteries with PSi- Based Electrodes

Gael Gautier, François Tran-Van, and Thomas Defforge

15.1 Introduction

Since its commercialization in the early 1990s, Li-ion batteries have tried to follow the ever-increasing needs for energy storage systems, in particular for the electric/hybrid vehicles and other nomad applications (Armand and Tarascon 2008). Despite remarkable improvements over the last two decades, Li-ion batteries still suffer from limited energy density as compared to fossil energies. As every electrochemical storage device, Li-ion batteries are composed of two electrodes immersed in an electrolyte containing Li+ ions. The cathode is typically made of either LiCoO2, LiNi1/3 Mn1/3Co1/3O2, or LiFePO4 while the anode consists ...
