Sodium-ion batteries are set to spark a renewable energy revolution – and Australia must be ready – ET Auto

Baua Electric

Some types of lithium mining require a lot of water and energy and have led to local pollution, such as in South America’s alpine lakes. But limits to these technologies can undermine the case for a renewables-only electricity mix. Sodium-ion batteries are now almost ready to fill the long-term storage gap.

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.

Energy Harvesting for Wearable Technology Steps Up

Cars That Think

And today, technology is maturing to the point that meaningful amounts of these energy giveaways can be harvested to liberate wearables from ever needing a battery. Using built-in fuel cells, the device absorbed the lactate in the sweat and combined it with atmospheric oxygen to generate water and pyruvate. volts for about 60 hours.

Caltech engineers devise new thermochemical cycle for water splitting for H2; recyclable, non-toxic, non-corrosive and at lower temperatures

Green Car Congress

Providing a possible new route to hydrogen-gas production, researchers at the California Institute of Technology (Caltech) have devised a new manganese-based thermochemical cycle with a highest operating temperature of 850?°C Davis’ first paper as a graduate student dealt with the sulfur-iodine low-temperature water-splitting cycle.).

Researchers develop rechargeable hybrid-seawater fuel cell; highly energy density, stable cycling

Green Car Congress

Researchers from Ulsan National Institute of Science and Technology (UNIST) in Korea and Karlsruher Institute of Technology in Germany have developed a novel energy conversion and storage system using seawater as a cathode. Similarly, sodium has recently attracted attention as a replacement for lithium in alkali-metal-air batteries.
