Amprius Technologies (AMPX) 2024 Annual Gateway Conference summary

Technology leadership and product innovation

• Developed silicon anode-based lithium-ion batteries with energy densities up to 500 Wh/kg and 1,300 Wh/L, doubling current market standards.

• Unique SiMaxx (nanowire) and SiCore (sphere) platforms enable 100% silicon anode, outperforming typical 3–6% silicon content in competitors.

• Batteries offer rapid charging (0–80% in under 6 minutes), high power density, and wide operating temperature range (-30°C to 55°C).

• Products validated in demanding applications, including US military and Airbus high-altitude pseudo-satellites.

• New cylindrical cells (21700, 18650) deliver 25–50% more energy for the same size compared to industry norms.

Market focus and customer applications

• Primary focus on aviation and micromobility, with growing engagement in military, marine, industrial, and consumer electronics sectors.

• Batteries enable significant performance improvements: e.g., doubling flight time for Airbus drones and extending wearable battery life for the US military.

• Micromobility market (e-bikes, scooters) represents a fast-growing, multi-gigawatt opportunity, especially in Europe and Asia.

• Customization available for unique customer needs, with 14 off-the-shelf SKUs and tailored solutions.

• Size and weight reductions of 40–50% achieved in real-world deployments, such as military wearables.

Manufacturing strategy and capacity

• Utilizes both in-house facilities (Fremont, Colorado) and contract manufacturing partners in Asia and soon Europe.

• Manufacturing leverages standard industry equipment, enabling rapid scaling and use of excess global capacity.

• SiMaxx production is sold out through next year; SiCore platform offers virtually unlimited capacity.

• Current operational capacity is near 1 GW, with over 500 MW available and plans to exceed 1 GW next year.

• Contract manufacturing model allows flexible, capital-efficient expansion.
