Fun facts about Amprius Technologies, Inc.

1
The Basics
U.S. advanced materials company · listed on NYSE · headquartered in California · operates in the energy storage sector.
2
The Numbers
A small-cap, pre-revenue-scale company still in commercialization mode — its balance sheet is more about R&D burn than quarterly profits.
3
The History
Spun out of research originally developed at Stanford University, it went public via a SPAC merger in the early 2020s to fund its manufacturing ambitions.

The Secret
Its secret weapon is a silicon anode — replacing graphite inside lithium-ion cells to pack dramatically more energy into the same physical space.
5
The Lore
Its batteries have already flown in high-altitude, long-endurance drones for aerospace and defense customers — not your average AA cell.
6
The Giveaway
