What lithium-metal batteries are, why the lithium-metal anode is so powerful and so hard, the dendrite problem, where they stand in 2026, and how to test cells.

Xnergy supplies the SPAN and SSPN lithium-sulfur cathode family: SPAN (~50% S) and high-sulfur SSPN (>79% S) powders, electrode sheets, dry pouch cells, and custom cells.

LFP vs NMC batteries compared on energy density, cost, safety, cycle life and temperature - plus which cathode to choose for your application in 2026.

What a sodium-ion battery is, how it works, why it's cheaper than lithium, the materials inside, who's building it in 2026, and how to build and test cells.
