New liquid alloy electrode significantly lowers operating temperature of sodium-beta batteries; improved performance

Green Car Congress

Researchers at Pacific Northwest National Laboratory (PNNL) have devised an alloying strategy that enables sodium-beta batteries to operate at significantly lower temperatures. The new electrode enables sodium-beta batteries to last longer, helps streamline their manufacturing process and reduces the risk of accidental fire.

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

Example of a lithium-water rechargeable battery. Researchers at the University of Texas, including Dr. 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.

Fraunhofer researchers develop new low-cost dry-film electrode production process

Green Car Congress

Researchers at the Fraunhofer Institute for Material and Beam Technology IWS in Dresden have developed a new battery cell production process that coats the electrodes of the energy storage cells with a dry film instead of liquid chemicals. This simplified process saves energy and eliminates toxic solvents.

Lux: Li-ion dominating grid storage market with 90% of 2014 proposals

Green Car Congress

Lithium-ion (Li-ion) batteries have become the dominant new technology in grid storage, capturing a 90% share of systems proposed last year, according to analysts at Lux Research. Molten salt batteries—consisting almost entirely of sodium-sulfur (NaS)—account for 23% of all deployed MW and 64% of deployed MWh respectively.
