New long-duration, extended capacity Na-Al battery design for grid storage

Green Car Congress

Researchers led by the Department of Energy’s Pacific Northwest National Laboratory (PNNL) have extended the capacity and duration of sodium-aluminum batteries. The new sodium-based molten salt battery uses two distinct reactions. h is achieved with an estimated raw active materials cost of $7.02 of peak charge capacity.

Stanford team develops sodium-ion battery with performance equivalent to Li-ion, but at much lower cost

Green Car Congress

Stanford researchers have developed a sodium-ion battery (SIB) that can store the same amount of energy as a state-of-the-art lithium ion, at substantially lower cost. Thus, further research is required to find better sodium host materials. —Lee et al.

New high energy, highly stable cathode for sodium-ion batteries

Green Car Congress

F 0.7 , for sodium-ion (Na-ion) batteries (NIBs). Large-scale energy storage systems are needed to deal with intermittent electricity production of solar and wind. Recently, attention has been refocused on room-temperature Na-ion batteries (NIBs) as a low-cost alternative technology as compared to LIBs. Click to enlarge.

Univ. of Texas researchers propose lithium- or sodium-water batteries as next generation of high-capacity battery technology; applicable for EVs and grid storage

Green Car Congress

John Goodenough, are proposing a strategy for high-capacity next-generation alkali (lithium or sodium)-ion batteries using water-soluble redox couples as the cathode. The present sodium-sulfur battery operates above 300 °C. The high energy storage has stimulated a worldwide study of Li-air batteries. V and charges at 4.2-4.4

Molten-Salt Battery Freezes Energy Over a Whole Season

Cars That Think

Especially for sources like wind and solar, which have discontinuous availability. A recent study from the Pacific Northwest National Laboratory (PNNL) looks at molten-salt batteries that can “freeze” their charge for months until required. He expects the battery to retain over 80% of its charge in that period.
