Conclusive summary and perspective Lithium-ion batteries are considered to remain the battery technology of choice for the near-to mid-term future and it is anticipated that significant to substantial further improvement is possible.
This emerging field intimately correlates with the topics of rechargeable batteries, nanomaterials, on-chip microfabrication, etc. In recent years, a number of novel designs are proposed to increase the energy and power densities per footprint area, as well as other electrochemical performances of microsized lithium-ion batteries.
High energy lithium and lithium ion batteries are playing a key role in the advent of the information age and will continue to expand their applications in many different aspects in the foreseeable future . They are categorized into two groups: primary batteries and secondary (rechargeable) batteries.
In fact, compared to other emerging battery technologies, lithium-ion batteries have the great advantage of being commercialized already, allowing for at least a rough estimation of what might be possible at the cell level when reporting the performance of new cell components in lab-scale devices.
