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.

EV Guru: Sodium-Ion Batteries are Coming Sooner Than You think!

Plug In India

Video: EV Guru: Sodium-Ion Batteries are Coming Sooner Than You think! The mining industry cannot keep up with the demand, so the alternative is to manufacture batteries based on sodium chemistry. The big issue with sodium-ion batteries is that they can store only about two-thirds of the energy of Li-ion batteries of equivalent size.

U-M leads new DOE-funded research center for ceramic ion conductors; MUSIC

Green Car Congress

The University of Michigan (U-M) and eight partner institutions will explore the use of ceramic ion conductors as replacements for the traditional liquid or polymer electrolytes in common lithium-ion batteries for electric vehicles and in flow cells for storing renewable energy in the grid.

Carnegie Mellon researchers develop semi-liquid lithium metal anode for use with solid electrolytes

Green Car Congress

The SLMA consists of lithium microparticles evenly distributed in a dual-conductive polymer matrix. However, researchers have found that the contact between the ceramic electrolyte and a solid lithium anode is insufficient for storing and supplying the amount of power needed for most electronics.

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. A = lithium or sodium (Li or Na), M represents a metal and 1 ≤ n < z. —Lu et al.

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

Green Car Congress

BroadBit uses it to produce new types of sodium-ion batteries. First, they mix the active materials, intended later to release the stored energy, with additives to create a paste. The shear forces in this system tear entire molecular chains out of the binder polymers. They process this dry mixture in a rolling mill.
