PATHION develops new LiRAP-based solid-state electrolytes for Li-sulfur and sodium-ion batteries

Green Car Congress

Supported by an ARPA-E grant, LiRAP has proven to be a safe alternative compared to the liquid electrolytes used in most of today’s lithium ion batteries. The LiRAP solid electrolytes conduct Li + ions well at high voltage and high current, providing much enhanced energy density and power capacity as well as safety.

Can Flow Batteries Finally Beat Lithium?

Cars That Think

The cell of a flow battery uses two chemical solutions containing ions, one acting as the anolyte (adjacent to the anode), the other as the catholyte (near the cathode). Typical redox flow batteries use ions based on iron chromium or vanadium chemistries; the latter takes advantage of vanadium’s four distinct ionic states.
