Research and development of high energy solid lithium-ion battery

This method may accelerate the development of high-energy solid-state lithium batteries, as well as other energy storage and transmission devices(such as fuel cells).

The new method relies on the way of lattice of solid lithium ion conductors, which is associated with the way of inhibiting ion migration, and helps to find new enhanced ion mobility materials that can support rapid charging and discharge. At the same time, this method can be used to reduce the reactivity of the material and the battery electrode, thereby shortening its service life. Better ion mobility and lower reactivity, these two characteristics are often mutually exclusive.

The initial idea of the MIT team was to understand and control water decomposition catalysts and apply them to ion conduction. This process is not only the core of rechargeable batteries, but also the core of other key technologies such as fuel cells and desalination systems. The researchers observed a good correlation between the determined lattice properties and the conductivity of lithium ion conductor materials. The vibration frequency of lithium itself can be cleverly changed by adjusting its lattice structure and using chemical substitutes or adulterants.

The researchers say the new approach could provide a powerful tool for developing new materials with better performance, which could significantly increase storage capacity and safety. The technology is also suitable for the analysis of materials for other electrochemical processes, such as solid oxide fuel cells, membrane desalination systems, or oxygen-producing reactions. The project was supported by BMW, the National Science Foundation and the United States Department of Energy.
