Researchers recently claimed that a method to design and analyze novel ion conductors, which play a key role in rechargeable batteries component, could speed the development process of high-energy lithium batteries, delivery devices, and energy storage, for instance, fuel cells.
The new way depends on the perspective of how the vibrations in a crystal lattice of lithium ion conductors move, comparing with the method of inhibiting ion movement. This offers a method to determine new materials with superior ion mobility, enabling swift charging and discharging. In the same phase, the technique can be utilized to eliminate the materials reactivity with electrodes of battery that can abbreviate the productive life. Mainly two main characteristics are believed to be more commonly exclusive; low reactivity and improved ion mobility.
The development of this new model was led by Professor of Energy Yang Shao-Horn, W.M. Keck, graduate student Sokseiha Muy, and recently graduated Bachman Ph.D. ’17, and Livia Giordano, a research scientist and with nine other researchers from Oak Ridge National Laboratory and MIT.
This new concept and joint efforts of all the researchers will turn out to be an influential tool for creating new and efficient performing materials that could result in drastic improvement in the overall capability of the power storage in the battery of given weight and size along with increased safety. The researchers also claimed that the technique can also be deployed for identifying the suitable materials for various electrochemical processes such as solid-oxide fuel cells, oxygen-generating reactions or membrane-based desalination systems.
The overall team behind the development of this method comprise Hao-Hsun Chang at MIT, Ryoji Kanno and Santoshi Hori at Tokyo Institute of Technology, Filippo Maglia, Peter Lamp Saskia Lupart at Research Battery Technology at BMW Group in Munich, Dipanshu Bansal, Douglas Abernathy, and Olivier Delaire at Oak Ridge.
The effort was backed by the U.S. Department of Energy, BMW, and the National Science Foundation.
