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. Credit: ACS, Lu et al.

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

Green Car Congress

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. Sodium can serve as an alternative to lithium in rechargeable batteries as the reversible storage mechanisms for sodium ions are very similar (e.g.,

Army Research Lab discovers aluminum nanomaterial rapidly splits water on contact

Green Car Congress

Researchers at the US Army Research Laboratory (ARL) have discovered that a nano-galvanic aluminum-based powder of their design splits water on contact, producing hydrogen and oxygen. The team demonstrated a small radio-controlled tank powered by the powder/water reaction.

Can Flow Batteries Finally Beat Lithium?

Cars That Think

As she drives her electric vehicle to her mother’s house, Monique’s battery gauge indicates that it’s time to reenergize. The battery in her EV is a variation on the flow battery , a design in which spent electrolyte is replaced rather than recharged. A battery that mitigates these problems is DARPA’s objective.

SiGNa Chemistry Demonstrates Sodium Silicate-Based Hydrogen Generation System for Portable Fuel Cells

Green Car Congress

Prototype sodium silicate hydrogen generation system as presented earlier this year at DOE merit review. The H300 utilizes real-time swappable cartridges that generate hydrogen on demand using SiGNa’s proprietary sodium silicide (NaSi) powder. Sodium-Silica-Gel: 2Na-SG + H 2 O → H 2 + Na 2 Si 2 O 5.

ORNL advancing LDH sorbent to recover lithium from geothermal brine wastes

Green Car Congress

It is essential for the manufacturing of lithium-ion batteries commonly used for everything from electric vehicles to cell phones and laptops. These plants pump hot water from geothermal deposits and use it to generate electricity. The technique is very sensitive to hydrogen atoms, making it ideal for studying water.
