Battery cell with a softly glowing edge
Pure-silicon anodes

More energy in the same battery.

SINEONE replaces graphite in the anode with pure silicon. Up to 40% more energy, or the same energy in a smaller, lighter battery.

One cell. Every device that runs on a battery.

Drones, AI glasses, phones and robots all hit the same wall: battery life. SINEONE moves it.

Inside the cell

Three layers do the work.

Every lithium-ion battery has a cathode and an anode, kept apart by a thin separator.

Charging moves lithium into the anode.

The more lithium the anode can hold, the more energy the battery stores. Today that anode is graphite, and graphite is full.

SINEONE: pure silicon.

Silicon holds up to ten times more lithium than graphite. Same cell, up to 40% more energy, with 584+ cycles validated by an independent lab.
