Über dieses Buch

Research on deformable and wearable electronics has promoted an increasing demand for next-generation power sources with high energy/power density that are low cost, lightweight, thin and flexible. One key challenge in flexible electrochemical energy storage devices is the development of reliable electrodes using open-framework materials with robust structures and high performance.

Based on an exploration of 3D porous graphene as a flexible substrate, this book constructs free-standing, binder-free, 3D array electrodes for use in batteries, and demonstrates the reasons for the research transformation from Li to Na batteries. It incorporates the first principles of computational investigation and in situ XRD, Raman observations to systematically reveal the working mechanism of the electrodes and structure evolution during ion insertion/extraction. These encouraging results and proposed mechanisms may accelerate further development of high rate batteries using smart nanoengineering of the electrode materials, which make “Na ion battery could be better than Li ion battery” possible.

Chapter 5. SnS Array for Anode of Na-Ion Battery

Abstract
In perusing low cost and safe energy storage technologies, one of the most appealing alternatives is to use Na instead of Li because sodium ion batteries (NIBs) do offer the “only” prospects of the very same performance as lithium ion batteries (LIBs) with a much better long-term sustainability perspective.

Chapter 6. Conclusion and Future Work

Abstract
There are six chapters in this dissertation. Chapter 1 is the general background introduction and mechanism of Li- and Na- ion batteries. Some traditional electrode materials for both cathode and anode are also reviewed for both LIBs and SIBs. The research motivation, targets and methods are also introduced.
