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.

Ningbo researchers propose mixed-ion Li/Na batteries

Green Car Congress

Schematics of Li + /Na + mixed-ion battery. Lithium-intercalation compounds and sodium-intercalation compounds are used for anode and cathode, respectively. Among these, the Ningbo team notes, is that only a couple of materials have been reported for the deintercalation/intercalation of sodium ions in aqueous media.

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.

Electric Car Manufacturers Inspire New Paradigms -- Seeking Alpha

Tony Karrer Delicious EVdriven

The MiEV runs on a lithium-ion battery pack that can be charged in seven or so hours on a 240-volt line. The electric car features three different battery options, two different Lithium-based (LI) systems – A123Systems and Enerdel as well as a Sodium-Nickel battery Zebra (Mes-Dea). safety requirements.
