GE testing sodium halide battery/Li-ion battery/fuel cell hybrid system for transit bus

Green Car Congress

GE’s ecomagination.com publication reports that GE engineers have begun testing a transit bus equipped with a new hybrid energy system integrating GE’s Durathon sodium-halide battery ( earlier post ), a lithium-ion battery and a hydrogen fuel cell. Better power management also means long-term savings in operating the vehicle.

Sodium-Ion Powered EVs Roll off From Chinese EV Factories

Get Electric Vehicle

The first mass-produced electric vehicle (EV) using a sodium-ion battery has been introduced by JAC Motors. While lithium-ion batteries are more developed and have a higher density than sodium-ion batteries, sodium-ion batteries are cheaper, dependable, and have better cold-weather performance.

Researchers convert atmospheric CO2 to carbon nanofibers and nanotubes for use as anodes in Li-ion and Na-ion batteries

Green Car Congress

Researchers from George Washington University and Vanderbilt University have demonstrated the conversion of atmospheric CO 2 into carbon nanofibers (CNFs) and carbon nanotubes (CNTs) for use as high-performance anodes in both lithium-ion and sodium-ion batteries. times above that of sodium-ion batteries with graphite electrodes.

Li-ion battery waste used in biodiesel production from discarded vegetable oil

Green Car Congress

Brazilian researchers have demonstrated a new chemical approach for producing biodiesel from domestic cooking oil waste by using lithium hydroxide mixed with either sodium hydroxides or potassium hydroxides as catalysts. Before, in practice, these were just restricted to sodium hydroxide and potassium hydroxide.

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

Green Car Congress

Schematic illustration of the designed hybrid-seawater fuel cell and a schematic diagram at the charged–discharged state. As described in an open access paper in the journal NPG Asia Materials , the system is an intermediate between a battery and a fuel cell, and is accordingly referred to as a hybrid fuel cell. earlier post ).

New mesoporous crystalline Si exhibits increased rate of H2 production; potential use in Li-ion batteries also

Green Car Congress

These advantages also make the mesoporous silicon a potential candidate for other applications, such as optoelectronics, drug delivery systems and even lithium-ion batteries. They then treat the material with a sodium potassium alloy. There are some processes that use sodium potassium alloy at industrial levels.

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 was developed.
