Amprius Technologies (NYSE:AMPX), a leader in silicon anode lithium-ion batteries, today announced it has secured a purchase order totaling $21 million for its SiCore^® cylindrical cells from a new premier electric mobility customer in China. Amprius cells were chosen for the company's suite of light electric vehicles, including scooters, three-wheelers, and motorcycles.

Amprius' SiCore cells deliver high energy density and long cycle life for electric mobility applications. The 30 Ah-capacity cells increase energy density by up to 100% compared to conventional graphite-anode cells. Cycle life is rated at more than 2,000 cycles.

"Current conventional batteries used in two and three-wheelers are constrained by their inherently low energy density," said Tom Stepien, CEO of Amprius. "Our silicon anode technology addresses this shortcoming by delivering higher energy density while maintaining the cycle life that these applications require. This purchase order underscores the increasing demand for higher-performance batteries in high-volume mobility markets and marks an important step in expanding our global business."

The battery market for light electric vehicles – e-scooters, e-bikes, three-wheelers, and electric motorcycles – is growing at a 15% compound annual growth rate and is projected to reach 26 GWh by 2030, according to a market study completed by Ratel Consulting. Growth is driven by urban mobility needs and increasing electrification. Amprius believes its battery technology is well-positioned to meet this growing demand by delivering longer range and improved performance.
