The Fortune Global 500 technology company has a strong presence in the LEV industry and is looking to enhance its product offerings through this strategic partnership with Amprius. The potential future business associated with the non-binding LOI could provide Amprius with battery production orders exceeding 2 GWh over the proposed contract’s duration.

Under this LOI, Amprius will design and deliver high energy density cylindrical cells based on Amprius’ SiCore anode chemistry with a 25% capacity improvement over the current industry standard. While the performance specifications are still being finalized, this development aims to substantially increase energy capacity, marking a significant milestone for both companies. Amprius has secured over 125 million SiCore cylindrical cell annual production capacity through contract manufacturing partnerships. Additional capacity will be available in 2025.

“This partnership further demonstrates Amprius’ industry-leading battery performance and its ability to significantly improve product range and performance across a variety of industries,” said Dr. Kang Sun, CEO of Amprius Technologies. “As we continue to transform the electric mobility sector, we are beginning to make strong inroads in the light electric vehicle space. We are excited to add another Fortune Global 500 company to our robust list of customers who trust Amprius to power their devices and products. The batteries for this application will take advantage of Amprius' new breakthrough SiCore cell chemistry and cylindrical cell design.”

Amprius will begin shipping the first group of SiCore cylindrical cells designed for this application to the customer this year.

The LEV market is expected to grow rapidly, reaching an estimated $205.7 billion by 2032, with a compound annual growth rate (CAGR) of 9.74% from 2023 onward, according to a Providence Research Report. This growth will continue to drive increasing demand for high-performance batteries across the micro-mobility sector.
