MIT-led team devises new approach to designing solid ion conductors; implications for high-energy solid-state batteries

Green Car Congress

Researchers led by a team from MIT, with colleagues from Oak Ridge National Laboratory (ORNL), BMW Group, and Tokyo Institute of Technology have developed a fundamentally new approach to alter ion mobility and stability against oxidation of lithium ion conductors—a key component of rechargeable batteries—using lattice dynamics.

JCESR team advances prospects of solid-state magnesium-ion batteries with discovery of fastest magnesium-ion solid-state conductor

Green Car Congress

However, poor mobility of Mg 2+ (and other multivalent cations) prevents the development of a broad spectrum of cathode materials, as are available to lithium- and sodium-ion battery technologies. Other co-authors on the paper are Juchaun Li of Berkeley Lab, William Richards and Yan Wang of MIT, and Tan Shi and Yaosen Tian of UC Berkeley.

Sadoway and MIT team demonstrate calcium-metal-based liquid metal battery

Green Car Congress

MIT professor Donald Sadoway and his team have demonstrated a long-cycle-life calcium-metal-based liquid-metal rechargeable battery for grid-scale energy storage, overcoming the problems that have precluded the use of the element: its high melting temperature, high reactivity and unfavorably high solubility in molten salts.
