Amprius Tech Stock Price, News & Analysis

Amprius Technologies (NYSE: AMPX) has announced a strategic contract manufacturing agreement with a leading battery manufacturer in South Korea to produce its SiCore® silicon anode cells. The partnership aims to expand Amprius' global production footprint and enhance its ability to meet rising demand for high-performance lithium-ion batteries.

The South Korean facility will manufacture cells according to Amprius' specifications, supporting both current and next-generation battery platforms for aerospace, defense, and electric mobility applications. Initial production will focus on a balanced SiCore cell for advanced drones. This agreement adds to Amprius' existing 1.8 GWh of contracted production capacity, strengthening its supply chain resilience and improving delivery efficiency for global customers.

Amprius Technologies (NYSE: AMPX) announced that its silicon anode batteries powered AALTO's Zephyr high-altitude pseudo-satellite (HAPS) aircraft to achieve a world-record 67-day continuous flight in the stratosphere, concluding on April 28, 2025. The unmanned Zephyr aircraft, operating at 70,000 feet, surpassed its previous record of 64 days, marking the longest continuous aircraft flight ever recorded. The solar-powered vehicle relies on Amprius' ultra-high-energy-density lithium-ion cells for overnight power, with solar panels charging the batteries during daylight hours. This achievement demonstrates the potential of HAPS platforms for both commercial and defense applications, including border surveillance, secure communications relay, and environmental monitoring.
