5 Fastest-Growing Battery Technology Stocks to Buy

2. Electrovaya Inc. (NASDAQ:ELVA)

Electrovaya Inc. (NASDAQ:ELVA) is one of the fastest-growing battery technology stocks to buy.

On April 7, 2026, the company was tied to a $5 million U.S. Department of Energy-backed project under the Critical Facility Energy Resilience program to design and deploy a 1.2MWh battery energy storage system at Binghamton University for a data-center test environment. The point is not just another battery demo. The project is meant to test peak shaving, backup power, and load management in a setting where AI-driven electricity demand is making data-center power quality and resilience a live infrastructure problem. Electrovaya said its Infinity system is positioned around safety and long cycle life, and the company framed the project as a model that could be replicated across other high-demand sites.

This ties Electrovaya to the AI-driven growth, which was earlier reinforced in its February quarterly results, where management said it was accelerating development of ultra-fast-charging battery technology and next-generation 800V DC energy storage solutions targeting robotics and data-center infrastructure. The company is also expanding its Jamestown, New York, facility with support from a $50.8 million EXIM loan, with management saying the site is intended to produce proprietary cells and improve margins through vertical integration once commercial shipments begin.

Electrovaya Inc. (NASDAQ:ELVA) is a technology-driven lithium-ion battery company commercializing its proprietary Infinity Battery Technology, designed for safety, longevity, and performance in industrial, robotics, defense, and energy-storage applications.
