Development of High Performance and Sustainable Na-ion Batteries for Stationary Electrical Energy Storage
Abstract
This report describes the status of advanced sodium-ion battery research being performed at Pacific Northwest National Laboratory for the U.S. Department of Energy’s Energy Storage Systems Program. The program will demonstrate a novel sodium-ion battery pouch cell with at least 50 mAh capacity capable of achieving $100/kWh projected materials cost at an energy retention > 80% over 250 cycles.Published: September 22, 2026
