Practice-oriented guide systematically summarizing and condensing the development, directions, potential, and core issues of sodium-ion batteries
Sodium-Ion Batteries begins with an introduction to sodium-ion batteries (SIBs), including their background, development, definition, mechanism, and classification/configuration, moving on to summarize cathode and anode materials, discuss electrolyte, separator, and other key technologies and devices, and review practical applications and conclusions/prospects of sodium-ion batteries.
The text promotes the idea that SIBs can be a good complement, or even a strong competitor, to more mainstream energy technologies in specific application scenarios, including but not limited to large-scale grid energy storage, distributed energy storage, and low-speed electric vehicles, by virtue of considerable advantages in cost-effectiveness compared with lithium-ion, lead-acid, and vanadium redox flow batteries. This book delves into what we have done, where we are, and how we should proceed in regards to the advancement of SIBs, in order to make the technology more applicable in real-world situations.
Specific sample topics covered in Sodium-Ion Batteries include: - Electrochemical test techniques, including cyclic voltammetry, galvanostatic charge-discharge, and electrochemical impedance spectroscopy - Advanced characterization techniques and theoretical calculation, covering imaging and microscopy, and the synchrotron radiation x-ray diffraction technique - Designing and manufacturing SIBs, covering types of cells (cylindrical, soft-pack, and psitmatic), and design requirements for cells - Performance tests and failure analysis, covering electrochemical and safety performances test, failure phenomenon, failure analysis method, and cost estimation - Solid-state nuclear magnetic resonance spectroscopy, covering principles of ssNMR and shift ranges for battery materials
A complete review of an exciting energy storage technology that is undergoing a crucial development stage, Sodium-Ion Batteries is an essential resource for materials scientists, inorganic and physical chemists, and all other academics, researchers, and professionals who wish to stay on the cutting edge of energy technology.
