The Battery Show 2026

September 15–17, 2026 • Novi, MI

About this conference

The Battery Show is North America's largest advanced battery and EV technology event, drawing 15,000+ attendees and 650+ exhibitors to Novi, Michigan — deliberately positioned in the Detroit automotive corridor rather than a coastal tech hub. Coverage spans cell chemistry and manufacturing, electric vehicle components, charging infrastructure and grid-scale energy storage, serving automotive, stationary storage and portable electronics markets. The exhibition is free to attend, with paid conference tracks running alongside it. The attendee mix is notably engineering-heavy: process engineers, battery designers and supply chain buyers rather than policy or investment audiences, which is what distinguishes it from broader clean-energy events like RE+. Co-located shows on electric and hybrid vehicle technology share the floor, so a single badge covers a wider span than the name suggests.
