Une plainte pénale déposée en Finlande a semé un nouveau doute sur les affirmations de Donut Lab concernant une batterie à semi-conducteurs prête pour la production, soulevant des questions sur les mesures de performance, les démonstrations et la préparation à la fabrication.

Mercedes-Benz says the 2027 EQS gets a major overhaul, including an 800-volt architecture, a larger 122 kWh battery, quicker charging, higher recuperation, and optional steer-by-wire.

Cornex New Energy has introduced a 165 Ah sodium-ion prismatic cell for stationary storage, positioning the chemistry as a contender for frequency regulation and other large-scale applications.

Une équipe de recherche chinoise affirme qu’un nouvel électrolyte toutes saisons pourrait porter l’autonomie des VE au-delà de 600 miles tout en fonctionnant par froid extrême, rappelant que la compétition des batteries repose de plus en plus autant sur la fiabilité que sur l’énergie brute.

Un prototype de batterie sodium-ion du groupe BAIC atteint une charge complète en 11 minutes et 450 km d’autonomie, tandis que les livraisons mondiales de sodium-ion bondissent de 150 % en un an vers un déploiement à grande échelle.

Le responsable du programme Semi de Tesla a révélé à Jay Leno des détails d'ingénierie impressionnants en intention de production, y compris un pack batterie conçu pour durer plus longtemps que le camion lui-même et une réduction de poids qui améliore considérablement la compétitivité de charge utile par rapport aux rivaux diesel.

NanoMalaysia has revealed a sodium-ion battery prototype exceeding 300 watt-hours per kilogram, a milestone that could reshape the energy storage market.

Researchers use Flash Joule Heating to destroy forever chemicals while extracting 99% pure lithium from brine in seconds.

Independent testing confirms Donut Lab's solid-state battery retains 97.7% charge after 10 days, but the startup's most extraordinary claims remain unverified.

China has deployed a sodium-ion battery in a production electric vehicle for the first time, achieving a 248-mile range and potentially disrupting the lithium-dependent EV supply chain.

BYD unveils Blade Battery 2.0 with over 1,000 km pure electric range and ultra-fast charging, debuting in the Yangwang U7 luxury sedan.

Finland's VTT research center confirmed Donut Lab's solid-state cell gained capacity at extreme heat, but key claims on density and cycle life remain unverified.

A startup called Donut Lab claims to have achieved a significant advance in solid-state battery technology, a long-sought holy grail that could transform electric vehicles and energy storage. But the company now faces the hardest part: convincing a skeptical industry that the breakthrough is real.

After years in the shadow of lithium-ion technology, sodium-ion batteries are poised for commercial takeoff in 2026. Multiple manufacturers are scaling production, costs are plummeting, and the technology's advantages in safety and resource availability are making it increasingly attractive for grid storage and affordable EVs.

University of Surrey researchers have discovered that keeping water in sodium-ion battery cathodes nearly doubles their energy storage capacity. The counterintuitive finding upends conventional wisdom that water must be removed from battery materials during manufacturing.

The Department of Energy is funding six teams to develop batteries capable of delivering four times the energy density of current technology. The teams have two years to produce manufacturable prototypes that could transform applications from military equipment to electric vehicles and grid storage.

A promising AI-driven materials science startup has secured $8 million in funding to revolutionize how electric vehicle components are discovered and developed. The company uses machine learning to compress years of laboratory research into weeks.
