Sodium battery technology operates on the same basic principle as most other battery technologies: electrochemical energy storage. This involves the movement of sodium ions between a cathode and an anode within the battery cell during charging and discharging cycles.
UChicago's Pritzker Molecular Engineering and UC San Diego's Laboratory for Energy Storage and Conversion have developed the world's first anode-free sodium solid-state battery. This innovation promises inexpensive, fast-charging, and high-capacity batteries for Electric Vehicles and grid storage.
In May 2023, we launched our largest European battery-based energy storage project at the Antwerp platform in Belgium. With its 40 containers, the site will develop a capacity of 75 MWh, which is equivalent to the daily consumption of almost 10,000 homes.
Battery storage prices have gone down a lot since 2010. In 2025, they are about $200–$400 per kWh. This is because of new lithium battery chemistries. Different places have different energy storage costs.
BAIC's prismatic sodium-ion cells achieve 4C charging, retain 92% energy at -20°C, and survive 200% overcharge without fire. (BAIC Group) has unveiled a prototype sodium-ion battery with industry-leading performance, signaling a further step forward in its next-generation battery development efforts. The company noted that the new battery complements its existing Aurora Battery platform. BAIC has disclosed new progress in sodium-ion battery development, as Chinese automakers expand the use of alternative battery chemistries alongside lithium-based systems to address cost, supply, and cold-weather performance constraints, according to IT-home. According to BAIC's research division. Chinese automaker BAIC is developing prismatic cells for sodium-ion batteries.
