Argonne researchers find cathode material synthesis a key reason for performance degradation of sodium-ion batteries

Green Car Congress

One of the more promising candidates for batteries beyond the current standard of lithium-ion materials is the sodium-ion (Na-ion) battery. Na-ion is particularly attractive because of the greater abundance and lower cost of sodium compared with lithium. This research was supported by DOE’s Vehicle Technologies Office.

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

In India, OLA Electric and Tata group have plans to make cells at a large scale. Demand for the element is so great for applications including electric vehicles, portable electronic devices, and stationary energy units, that lithium mining companies are struggling to keep up. Sodium is bigger and heavier than lithium cell.

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.

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.

Researchers devise electrode architectures to prevent dendrite formation in solid-state batteries

Green Car Congress

So far, the current densities that have been achieved in experimental solid-state batteries have been far short of what would be needed for a practical commercial rechargeable battery. In a second version, the team introduced a very thin layer of liquid sodium potassium alloy in between a solid lithium electrode and a solid electrolyte.
