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.

Tokuyama and Toyota start verification tests in Japan for stationary fuel cell generator that uses by-product hydrogen; Mirai FC system

Green Car Congress

By using components from the Mirai FC system—the FC stack, power control unit (PCU), secondary battery, and air compressor—Toyota seeks to produce a high-performance generator at a reasonable price. The FC generator has been set up within the Tokuyama Factory grounds in Shunan City, Yamaguchi Prefecture.

Univ. of Tokyo researchers demonstrate new “oxygen-rocking” battery

Green Car Congress

Researchers at the University of Tokyo have developed a battery based on the concept of a combination of a perovskite-type cathode and a low-electrode-potential anode that can achieve high energy densities through the use of organic rather than aqueous electrolytes. Earlier post.). FeO z , with 2.58 ? for the anode and 2.75 ?

Researchers show that inherent lithium ions in bioderived borate polymer enhance extreme fast charging capability in graphite anodes

Green Car Congress

In order to enable fast-charging ability in batteries, researchers have attempted to enhance the mass transfer of electrolytes and charge transfer in electrodes, with extensive research carried out on the former compared to the latter. It is an undesired process leading to reduced battery life and limiting fast charge capability.

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.
