A Korean research team says it has solved the biggest technical hurdle standing between today’s EVs and a 12-minute charge.
The breakthrough targets dendrites. Those are the needle-like crystals that grow inside lithium-metal batteries during fast charging. They’ve kept advanced cells from leaving the lab by shortening lifespan and increasing fire risk.
Now researchers at KAIST have developed an intelligent coating that rearranges itself. It keeps lithium ions moving smoothly, even under extreme electrical load.
The team added thiophene to the battery electrolyte. That creates a protective barrier with a flexible electronic structure.
Think of it like a smart traffic system that shifts lanes as cars merge. When lithium ions move, the charge distribution inside the layer changes. It creates optimal pathways on the fly.
Simulations confirmed this design beats existing commercial additives. The result was consistent charging at currents exceeding 8 mA per cm². That’s more than double what the field usually considers high.
The researchers didn’t just simulate success. They used in-situ atomic force microscopy to watch the battery at the nanometer scale during operation.
Even under high power, lithium deposited and removed itself uniformly on the surface. That visual proof confirms the mechanical reliability needed for real driving conditions.
The technology also works with common cathode materials including lithium iron phosphate and lithium nickel-cobalt-manganese oxide. That means it could integrate into existing EV battery production lines without a complete overhaul.
This work tackles the fundamental instability at the electronic structure level. It’s not just a material tweak.
By enabling stable high-current operation, it opens the door for lithium-metal batteries to finally reach real-world use. The team specifically mentions ultra-long-range electric vehicles as an immediate target.
But the applications stretch further. Urban air mobility and next-gen energy storage systems could also benefit from the density and speed this design allows.
The next step will be moving from demonstration to scaled manufacturing. That process will determine how soon you might see that 12-minute charge at an actual charging station.
BYD has launched the third-generation Qin Plus DM-i in China, and the first thing that caught my eye is its price. According to CarNewsChina, the plug-in hybrid sedan starts at 79,900 yuan, which is about $11,980. That’s an incredibly low price for a brand-new car, especially by US standards.
What’s even more impressive is the range. The Qin Plus DM-i can drive up to 137 miles on electricity alone, which should cover most people’s daily commutes without using a drop of gas. Once the battery runs out, the 1.5-liter engine takes over. Thanks to its 17-gallon tank and roughly 91 mpg with a drained battery, the combined range reaches up to 1,423 miles.
Apple won the PC market’s worst quarter, but that’s not the entire story. It won the race by stumbling less than everyone else.
PC makers shipped just 57 million computers worldwide in Q3, which might look good, but it’s a 21% year-over-year plunge (via Counterpoint Research). And despite Apple’s Mac shipments falling by 11%, to 5.6 million, its market share rose from 8.7% to 9.8%. How did that happen?
Update (October 22 23:54 PT): In response to our query, GM clarified that offline recording support is already available on eligible vehicles. Like Tesla's Sentry Mode, it requires owners to connect a USB drive to save incident recordings, which can be viewed on the vehicle's infotainment screen. The upcoming Connected Cameras feature will build on this by giving owners remote access to these recordings via the revamped OnStar app, allowing them to check footage without walking out to their car.
General Motors has announced plans to add a new Connected Cameras feature to its OnStar service starting next year, giving drivers a way to monitor parked vehicles remotely and capture footage of certain incidents.
