Uma denúncia criminal na Finlândia levantou novas dúvidas sobre as alegações da Donut Lab a respeito de uma bateria de estado sólido pronta para produção, colocando em questão métricas de desempenho, demonstrações e prontidão para fabricação.

A Mercedes-Benz afirma que o EQS 2027 recebe uma grande reformulação, incluindo arquitetura de 800 volts, uma bateria maior de 122 kWh, carregamento mais rápido, maior recuperação de energia e steer-by-wire opcional.

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.

Uma equipe de pesquisa chinesa diz que um novo eletrólito para todas as condições climáticas poderia elevar a autonomia dos EVs para além de 600 milhas enquanto opera em frio extremo, lembrando que a competição em baterias cada vez mais depende de confiabilidade tanto quanto de energia bruta.

Um protótipo de bateria de íons de sódio do BAIC Group consegue carga completa em 11 minutos e autonomia de 450 km, enquanto os embarques globais de íons de sódio disparam 150% em um ano rumo à adoção em massa.

O líder do programa Semi da Tesla revelou detalhes impressionantes de engenharia de intenção de produção para Jay Leno, incluindo um pacote de bateria projetado para durar mais do que o próprio caminhão e uma redução de peso que melhora dramaticamente a competitividade de carga útil contra rivais 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.
