Moonwatt brings DC-coupled, passively cooled sodium-ion tech to solar projects
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 now competitive in niche markets
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.
Scientists design low-cost sodium-ion battery with cheap electrode materials
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.
New design specifications for sodium-ion batteries
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.
Sodium-ion batteries: Unigrid begins commercial-scale deliveries; Altris and Draslovka partner to scale Europe’s supply chain
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.
Why sodium-ion can’t yet challenge lithium-ion’s reign
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.
