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.

Kampuni mpya inayoitwa Donut Lab inadai kufikia maendeleo makubwa katika teknolojia ya betri imara, lengo la muda mrefu linaloweza kubadilisha magari ya umeme na uhifadhi wa nishati. Lakini kampuni sasa inakabiliwa na sehemu ngumu zaidi: kushawishi sekta yenye shaka kwamba uvumbuzi ni wa kweli.

Baada ya miaka mingi katika kivuli cha teknolojia ya lithiamu-ioni, betri za sodiamu ziko tayari kuruka kibiashara mwaka wa 2026. Watengenezaji wengi wanaongeza uzalishaji, gharama zinashuka, na manufaa ya teknolojia katika usalama na upatikanaji wa rasilimali yanaifanya ivutie zaidi kwa hifadhi ya gridi ya taifa na EV za bei nafuu.

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.
