Sodium-Ion Energy Storage & Battery Symposium

Sodium-ion battery innovation is accelerating. In energy storage applications as well as next-gen EV batteries, sodium-ion is increasingly seen as a cost-effective, safer, and more sustainable alternative -- thanks to abundant sodium-based raw materials and favorable performance in stationary and hot-climate duty cycles. Indeed, the global sodium-ion battery market was valued at approximately US $270 million in 2024, and is forecast to grow at a CAGR of ~26% from 2025 to 2034, reaching around US $2.7 billion by 2034.*

To help industry stakeholders realize this opportunity, the Sodium-Ion Energy Storage & Battery Symposium, May 19-20, 2026 in Chicago, brings together the full value chain -- materials innovators, manufacturers, system integrators, utilities, and investors -- to explore how sodium-ion can scale, integrate, and impact the energy-storage and EV battery landscape. If your organization is involved in storage for e-mobility or grid-scale applications, this is a unique deep-dive into promise and progress of sodium-ion advances.

• Innovation in sodium-ion cell chemistry:
  Cathodes (layered oxides, Prussian white), anodes (hard carbon), electrolytes & temperature stability

• Manufacturing and scale-up:
  Production readiness, cost curves, supply-chain resilience, quality assurance

• System integration & deployment:
  Pack design, BMS architecture, safety & certification, thermal management, utility-scale use cases

• Sodium-ion advances and prospects for EV applications:
  Technology developments positioning sodium-ion as a key enabler for affordable, mass-market electric vehicles

• Utility and grid perspectives:
  Long-duration storage use cases, renewables firming, frequency regulation, sub-station reinforcement

• Commercialization & financing:
  Bankability criteria, warranty/performance guarantees, project financing pathways, risk mitigation

• And more

This event is designed for professionals from across the sodium-ion ecosystem, including:

• Battery-materials researchers and developers

• Cell and module manufacturers

• System integrators, BESS OEMs and EPC contractors

• Utilities, IPPs, grid operators and transmission/distribution executives

• Investors, financiers, and project-developers focused on energy-storage opportunities

• Policy-makers, regulators, and industry-association representatives interested in emerging storage technologies

• Consultants and strategic advisors serving the energy-storage, battery, and grid markets
