Chapter 8
Conclusion
This book describes various functional nanomaterials for electrochemical applications. It consists of four chapters that show interesting examples of nanomaterials
of different sizes. Two chapters show electrochemical energy storage applications
that rely on modern electrochemistry. It also includes the synthesis of functional
nanomaterials from quantum dots, one-dimensional nanostructures, two-dimensional
nanostructures to three-dimensional nanostructures. A review of the collective work
of functional nanomaterials in electrochemical applications illustrates the latest
advances in many modern electrochemical energy storage hotspots: lithium batteries,
lithium-ion batteries, sodium-ion batteries, other metal-ion batteries, halogen-ion
batteries, and metal–gas batteries.
Quantum dots exhibit properties that are intermediate between bulk semiconductors and discrete atoms or molecules. Due to its unique tunable photoluminescence
properties, excellent physicochemical properties, high light stability, biocompatibility, and small size, the emerging GQD and C-dots have received much attention due to their enormous potential for biomedical applications. The synthesis of
C-dots and GQD can generally be divided into top-down and bottom-up methods. The
1D nanostructure can provide a DC path, shorten the ion diffusion distance, reduce
the charge and discharge time, increase the electrolyte–electrode contact area, limit
mechanical degradation, and accommodate volume expansion. This synergistic effect
between each component imparts better conductivity to the heterostructure electrode,
greater electrochemical cycle stability and reversibility, faster ion transport, improved
mechanical stability, and the like. The synthesis of 1D nanostructures includes topdown and bottom-up methods as well. 2D nanomaterials have atomic thickness,
large surface area, tunable electronic properties, excellent mechanical strength, and
unique limiting effects. Methods for 3D nanomaterials include chemical precipitation, sol–gel, hydrothermal, solvothermal, thermal decomposition, microemulsion,
and chemical vapor deposition.
For the batteries, the sulfur reaction process is extremely complicated and the reaction intermediates are various. The electrochemical performance of lithium–sulfur
batteries is greatly influenced by the nature of the electrode materials, test conditions,
