Amprius Secures $21 Million Purchase Order for Advanced Silicon-Anode Batteries for Electric Two- and Three-Wheelers
Amprius Technologies, a global leader in silicon anode lithium-ion battery technology, has announced a major milestone in its growth trajectory, securing a purchase order worth $21 million from a premier electric mobility customer in China. The order covers Amprius’ flagship SiCore® cylindrical cells, which will power a new fleet of light electric vehicles, including scooters, three-wheelers, and motorcycles, reflecting the company’s expanding footprint in the high-performance EV battery market.
Amprius’ SiCore cells are specifically designed to address the limitations of conventional graphite-anode batteries. They deliver substantially higher energy density while maintaining exceptional cycle life, making them ideally suited for high-volume light electric mobility applications. Each SiCore cell features a 30 Ah capacity, offering up to a 100% increase in energy density compared to standard graphite-based cells, while supporting more than 2,000 charge-discharge cycles. This combination of performance metrics positions Amprius’ technology as a leading solution for the rapidly growing electric two- and three-wheeler market.
“Current conventional batteries used in two- and three-wheeled electric vehicles are constrained by their inherently low energy density,” said Tom Stepien, CEO of Amprius. “Our silicon anode technology addresses this limitation by delivering higher energy density while preserving the cycle life that is critical for daily urban mobility. This purchase order reflects the increasing market demand for higher-performance batteries in high-volume mobility applications and represents a significant step forward in our global expansion strategy.”
The selection of Amprius’ SiCore cells by a top-tier Chinese EV customer underscores the growing recognition of silicon-anode technology in commercial applications. Silicon anodes have been long regarded as the next-generation solution for lithium-ion batteries due to their ability to store significantly more lithium ions than traditional graphite anodes, which directly translates to longer range and improved efficiency.
Driving Performance in Electric Mobility
Light electric vehicles (LEVs) such as e-scooters, e-bikes, three-wheelers, and small motorcycles are at the forefront of urban transportation electrification. As cities around the world adopt policies to reduce emissions and improve air quality, the demand for compact, efficient, and high-performance electric mobility solutions is accelerating. However, conventional batteries have often limited the operational range and payload capacity of these vehicles, restricting their broader adoption.
Amprius’ SiCore cylindrical cells provide a direct solution to these constraints. By increasing energy density by up to 100%, vehicles equipped with SiCore batteries can travel farther on a single charge, carry heavier loads, and maintain consistent performance over time. The long cycle life of more than 2,000 cycles ensures that fleet operators and individual consumers alike benefit from reduced battery replacement costs and enhanced reliability.
“The deployment of our SiCore batteries in high-volume EV fleets is a clear validation of our technology,” added Stepien. “It demonstrates that silicon anode batteries are no longer limited to niche applications or laboratory-scale development. They are now ready to power commercial electric vehicles at scale.”
Market Growth and Opportunity
The battery market for light electric vehicles is experiencing rapid growth, driven by urbanization, government incentives, and the global push toward cleaner transportation. According to a market study by Ratel Consulting, the LEV battery sector is projected to grow at a compound annual growth rate (CAGR) of 15%, reaching a total of 26 GWh by 2030. Growth is particularly strong in China, India, and Southeast Asia, where dense urban populations and rising interest in micromobility solutions are fueling the adoption of electric scooters, e-bikes, and three-wheelers.
Amprius is strategically positioned to capture a significant share of this growing market. Its silicon-anode technology not only addresses current energy density limitations but also supports future innovations in electric mobility, including higher-capacity batteries for larger scooters and three-wheelers, as well as integration with next-generation vehicle management systems.
“Urban mobility is evolving rapidly, and battery performance is a key differentiator for both manufacturers and consumers,” said Stepien. “Our SiCore cells offer a unique combination of energy density, cycle life, and reliability, enabling EV manufacturers to meet the expectations of urban commuters while reducing environmental impact.”
Expanding Global Reach
This $21 million purchase order marks a critical step in Amprius’ international growth strategy. By partnering with a leading Chinese EV manufacturer, the company strengthens its presence in one of the largest and most dynamic electric mobility markets in the world. China continues to dominate global LEV sales, and the adoption of higher-performance silicon-anode batteries is expected to accelerate as manufacturers seek to differentiate their products through superior range, charging efficiency, and longevity.
In addition to its impact in China, Amprius is exploring opportunities in other fast-growing LEV markets, including India, Southeast Asia, and Europe. Urban congestion, stricter emissions regulations, and the rise of shared mobility models are all contributing to increased demand for advanced battery solutions capable of supporting extended range and intensive daily usage.
Technology Highlights: SiCore® Cylindrical Cells
Amprius’ SiCore cylindrical cells incorporate several proprietary innovations:
- High Energy Density: Up to 100% higher than conventional graphite-anode cells, enabling longer vehicle range.
- Long Cycle Life: Rated for more than 2,000 cycles, providing durability and cost efficiency over the lifetime of the vehicle.
- Thermal Stability: Designed to maintain safety and performance under varying environmental conditions.
- Lightweight Design: Optimized for use in scooters, motorcycles, and three-wheelers, contributing to vehicle efficiency and handling.
The combination of these features makes SiCore cells an attractive choice for electric mobility OEMs seeking to improve vehicle performance while managing total cost of ownership.
Amprius continues to invest in scaling its manufacturing capabilities to meet rising global demand. The company is focused on expanding production of SiCore cells while maintaining strict quality control standards, ensuring that each battery meets the rigorous requirements of high-volume electric mobility applications.
“Our vision is to lead the transition toward electrified urban transportation by providing battery technology that combines performance, safety, and reliability,” said Stepien. “This purchase order is a tangible demonstration of our ability to deliver commercially viable silicon-anode solutions at scale and represents just the beginning of what we expect to be substantial adoption across the global LEV market.”
As urban mobility continues to shift toward cleaner, more efficient solutions, Amprius’ advanced battery technology positions it as a key enabler for manufacturers, fleet operators, and consumers seeking reliable and high-performance electric vehicles. By bridging the gap between laboratory innovation and commercial deployment, Amprius is setting a new standard for energy storage in light electric mobility.
