Synthesis, Characterization and Electrochemical Studies of Active Materials for Sodium Ion Batteries

摘要

Sodium ion batteries represent an interesting alternative to lithium ion batteries for large scale energy storage, due to the inexpensive and massive sources of sodium. Moreover, the incertitude related to lithium resources and their suppliers could become a major problem in the coming years. In this study, synthesis and electrochemical analyses were performed to examine TiO_2 (B) and Na_2Ti_6O_(13)'s potential as negative electrode materials in sodium ion batteries. These materials were selected due to their well-known small cation insertion redox reactions.
