This focus allows Amprius to command premium pricing while positioning itself as an essential enabler of next-gen mobility and national security technologies.
As global demand accelerates for lightweight, high-performance energy storage solutions, Amprius is scaling its operations through a combination of contract manufacturing partnerships, U.S.-based production facilities, and global licensing opportunities. The company’s roadmap includes mass production of its SiCore™ and SiMaxx™ battery platforms, which are already undergoing qualification by Fortune 500 customers in aerospace and defense.
Now publicly traded on the New York Stock Exchange under the ticker AMPX, Amprius Technologies is not just riding the clean energy revolution—it’s powering it. By addressing the growing need for compact, high-efficiency energy storage, the company is redefining what’s possible for electric flight, space systems, and advanced mobility, making it one of the most disruptive and promising small-cap stocks in the energy technology space today.
Technological Edge: Silicon Anode Innovation for Maximum Energy Density
At the heart of Amprius’ value proposition is its silicon nanowire anode platform, a breakthrough in battery architecture that enables energy densities far beyond traditional graphite-based lithium-ion cells. The company’s recently launched SiCore™ battery delivers up to 450 Wh/kg and 950 Wh/L, making it the highest energy density commercially available lithium-ion cell on the market today.
Designed for ultra-light, high-endurance, and performance-critical use cases, the SiCore battery is already being evaluated by aviation and defense partners for deployment in High-Altitude and Medium-Altitude Platform Stations (HAPS and MAPS), unmanned aerial vehicles (UAVs), and electric aircraft systems. Amprius is solving one of the biggest challenges in modern aerospace and military engineering: delivering more energy without adding weight.
According to CEO Dr. Kang Sun, the SiCore product is “not just a scientific achievement—it’s ready to scale.” Unlike many early-stage technologies, Amprius’ solution has been specifically engineered to be compatible with existing lithium-ion battery manufacturing infrastructure, meaning it can be adopted at scale without the need for costly factory overhauls or delays in integration.
