This ultra-cheap, water-based iron battery could last 16 years without degrading

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.

How BYD engineered breakthrough five-minute EV charging

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.
