Molten-Salt Battery Freezes Energy Over a Whole Season

Cars That Think

As the pressure to decarbonize electricity grids mounts, so does the need to have long-term storage options for power generated from renewables. While rechargeable batteries are the solution of choice for consumer-level use, they are impractical for grid-scale consideration.

Report: Sumitomo and Kyoto University developing lower temperature molten-salt battery; about 10% the cost of Li-ion

Green Car Congress

in partnership with Kyoto University, has developed a lower temperature molten-salt rechargeable battery that promises to cost only about 10% as much as lithium ion batteries. Molten-salt batteries use highly conductive molten salts as an electrolyte, and can offer high energy and power densities.

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.

AIST researchers synthesize new class of high-voltage, high-capacity cathode materials for Li-ion batteries

Green Car Congress

A paper on their work is published in the Journal of Power Sources. Since the commercialization of Li-ion batteries by Sony in 1991, lithium cobalt oxide (LiCoO 2 ) has been extensively studied as a positive electrode material in rechargeable lithium batteries. One of the compositions—Na 0.093 Li 0.57 V at 25 ˚C (between 2.0

US Naval Research Lab scientists developing ionic liquid batteries

Green Car Congress

The use of these electrolytes suggests the potential for new types of rechargeable systems, such as replacement electrolytes in nickel-metal hydride (NiMH) batteries, or even the standard lead-acid battery. Experimental work is currently underway to develop such a rechargeable ionic liquid power source.
