sodium-ion batteries

The Natec Home has a nominal capacity of 7.68 kWh and a power output of 3.8 kW, and allows parallel connection of up to 15 units. The reference price is set at €3,990.

The European Economic and Social Committee (EESC) will place sodium batteries at the center of its work on the EU’s industrial strategy and is calling for swift action. pv magazine has compiled a list of manufacturers developing this technology in Europe.

The new SALT 110 battery storage system from the Vienna-based company has a usable capacity of up to 110 kWh. The storage system is reportedly capable of 6,000 charge cycles at a depth of discharge of 95%.

German researchers have developed a sodium-ion battery technology using lignin-based hard carbon as the negative electrode. The 1 Ah battery cell prototype showed no significant degradation after 100 charging and discharging cycles.

The Dutch start-up, founded by former Tesla leaders, is taking a novel approach to sodium-ion battery technology, optimizing it for integration with solar power plants. Its technology is set to be deployed for the first time in a Dutch solar-plus-storage project later this year.

Sodium‑ion batteries are emerging as a safer, lower-cost alternative to lithium‑ion, with a recent international study highlighting their competitiveness in stationary energy storage. The research shows that ongoing investment and supply-chain development could enable broader adoption within the next decade.

Conceived for stationary energy storage, the proposed sodium-ion battery configuration relies on an P2-type cathode material and an hard carbon anode material that reportedly ensure full-cell performance. Electrochemical testing revealed initial capacities of 200 mAh/g for the cathode and 360 mAh/g for the anode with capacity retentions of 42% and 67.4% after 100 cycles.

U.S. scientists used density functional theory to reveal how sodium ions are stored in nanoporous carbon anodes for sodium-ion batteries, identifying dual ionic and metallic storage mechanisms within the pores. Their findings provide practical design guidelines to improve battery voltage, safety, and commercial viability for stationary energy storage.

With lithium prices reaching a two-year high in early 2026, sodium-ion batteries are once again in the spotlight, as innovators on both sides of the Atlantic announce major milestones.

A new generation of sodium-ion (Na-ion) battery cells has been launched as an alternative to the virtual monopoly of lithium-ion (Li-ion). Although the technology is unlikely to displace significant Li-ion market share, recent improvements make Na-ion a viable solution for certain niche applications, with potential for wider usage if cost becomes competitive.
