Battery breakthrough for electric cars

"Breakthroughs" are announced every 3-4 days. It is ALL Vapourware until it reaches a point of being Manufacturable and is actually manufacturers. Lab Prototypes and limited test production do not mean they can actually be made in bulk at a reasonable cost. Typically take 5-7 Years from a COMPLETE TRIAL for Manufacturing to become a viable reality.
 
More investor bait. They all start out like this "Researchers at Xxxx"

Give me a working product, and THEN we'll talk. :)
 
“Can recharge a vehicle battery in 10-20 minutes!”

um...
120KWh in .33 hours... needs... 667AMPS at 600V...

What voltage are the recharging this “vehicle” battery at?

that's the easy part marty and doc brown figured it out back in the 50's. you just harness a lightning strike and direct it into the flux capacitor, easy 1.21 gigawatts...

Given current shipping times that is about right ;)

Ahh .... the voltage doesn’t matter because researchers are promising wireless charging.
No need for cumbersome 250 or 500 MCM charger cables!
 
" ... that can be charged and discharged at least 10,000 times — far more cycles than have been previously demonstrated — at a high current density. The researchers paired the new design with a commercial high energy density cathode material.

This battery technology could increase the lifetime of electric vehicles to that of the gasoline cars — 10 to 15 years — without the need to replace the battery."

Don't need 10,000 cycles. 3650 cycles gives you 10 years cycling once per day. If 300 miles per charge, that's 110,000 miles per year, 1 million miles in 10 years. Even that is 5x to total life needed for a more typical car owner who might drive 20,000 miles per year, 200,000 miles during ownership. Just 1000 cycles near 100% DoD would meet their needs, 2000 cycles would cover people who keep cars longer or are 2nd owner and bring the car to 300k or 400k miles.

We're used to having 200 to 400 mile range on a tank. less than that on a charge would be inconvenient, but a small battery drained 80% each way to work and recharged there could be OK. Say someone has an 80 mile commute, 100 mile battery. In that case 500 cycles per year, 12 years would be 6000 cycles to 80% DoD. In that case a 10,000 cycle battery of smaller capacity could be used for lower cost.
