New MIT metal-mesh membrane could solve longstanding problems with liquid metal displacement batteries; inexpensive grid power storage

Green Car Congress

A new metal mesh membrane developed by researchers at MIT could advance the use of the Na–NiCl 2 displacement battery, which has eluded widespread adoption owing to the fragility of the ?"-Al The results could make possible a whole family of inexpensive and durable materials practical for large-scale rechargeable batteries.

U Waterloo team identifies key reaction in sodium-air batteries; implications for improving Li-air

Green Car Congress

Chemists at the University of Waterloo have identified the key reaction that takes place in sodium-air batteries. Understanding how sodium-oxygen batteries work has implications for developing the more powerful lithium-oxygen battery, which has been proposed by some as the “holy grail” of electrochemical energy storage.

Researchers devise electrode architectures to prevent dendrite formation in solid-state batteries

Green Car Congress

So far, the current densities that have been achieved in experimental solid-state batteries have been far short of what would be needed for a practical commercial rechargeable battery. In a second version, the team introduced a very thin layer of liquid sodium potassium alloy in between a solid lithium electrode and a solid electrolyte.

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.

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.
