Amprius Sets December 2025 Events Schedule

Key Terms

lithium-ion batteries technical

Rechargeable lithium-ion batteries are lightweight, high-energy storage cells that use lithium ions moving between electrodes to store and release electricity, like a refillable fuel tank for electronic devices and electric vehicles. Investors care because they power a wide range of products from phones to cars and grid systems, so improvements, costs, supply chain constraints, or safety issues can directly affect manufacturers’ profits, product demand, and capital expenditure plans.

silicon anode platform technical

A silicon anode platform is a battery technology that uses silicon in the negative electrode instead of traditional carbon to store more electrical charge; think of it as swapping a small sponge for one that soaks up much more water. It matters to investors because it can enable batteries with higher range, faster charging, or lower cost per mile, but also carries technical and manufacturing risks that affect product timelines, costs and competitive advantage.
