The all-iron flow battery completed 6,000 cycles with no measurable capacity loss
Forward-looking: Lithium-ion batteries are everywhere, but their cost, supply chain issues, and potential to fail in fiery ways make them less than ideal for grid-scale energy storage. Chinese researchers say they have taken a major step toward an alternative in the form of an all-iron flow battery built from cheap, abundant materials and a water-based electrolyte that cannot explode.
Camera-based visibility takes over as Polestar redesigns airflow
First look: The 2026 Polestar 4 removes a feature that has defined automotive design for more than a century: the rear window. In its place, the vehicle uses cameras and sensors to provide rearward visibility, a move that is dividing opinion.
A rethink of cells, chargers, and infrastructure pushed EV refueling into gas-station territory
Connecting the dots: Chinese automaker BYD has pulled ahead of global rivals in a race many in the industry consider pivotal to mainstream electric vehicle adoption: charging speed. Through tight vertical integration, new battery chemistries, and aggressive infrastructure expansion, the company has shown that refueling an EV can now take minutes rather than half an hour.
The takeaway: A small car parked in a rainy British driveway might seem an unlikely place for a battery revolution. Yet that's where engineer and YouTuber Chris Doel has built the world's first vape-powered vehicle – a working proof of concept that challenges both the limits of lithium-ion recycling and society's growing mountain of electronic waste.
