NanoGraf unveils 3.8 Ah 18650 Li-ion cell, 800 Wh/L using silicon anode

Green Car Congress

NanoGraf, an advanced battery material company ( earlier post ), has enabled what it says is the highest energy density 18650 cylindrical lithium-ion cell in the world—one that provides a 28% longer run time than traditional cell chemistries. million grant to develop longer-lasting lithium-ion batteries to power US military equipment.

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.
