Pure lithium metal is a promising replacement for the graphite-based anodes currently used in electric vehicle batteries. It could tremendously reduce battery weights and dramatically extend the driving range of electric vehicles relative to existing technologies. But before lithium metal batteries can be used in cars, scientists must first figure out how to extend their lifetimes.

A new study led by Peter Khalifah—a chemist at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory and Stony Brook University—tracked lithium metal deposition and removal from a battery anode while it was cycling to find clues as to how failure occurs. The work is published in a special issue of the Journal of the Electrochemical Society honoring the contributions of Nobel Prize-winning battery researcher John Goodenough, who like Khalifah is a member of the Battery 500 Consortium research team.

“In a good battery, the rate of lithium plating (deposition) and stripping (removal) will be the same at all positions on the surface of electrodes,” Khalifah said. “Our results show that it’s harder to remove lithium at certain places, which means there are problems there. By identifying the cause of the problems, we can figure out how to get rid of them and make better batteries with higher capacities and longer lifetimes.”

Please friends how true is this?

Electricity generated from human walking and vehicles on the road can power road lights and signals.

We’re continuing to conduct integrated tests inside the Vehicle Assembly Building ahead of the Artemis I launch! The team will work to complete all remaining Space Launch System pre-flight diagnostic tests and hardware closeouts in advance of a mid-February rollout for a wet dress rehearsal in late February. NASA will set a target launch date after a successful wet dress rehearsal test.

In the early days of industrialization, most manufacturers were vertically integrated, including automakers. That changed over time, but the shift is reversing.

Elon Musk announces that Tesla will soon be joining the robotic industry. New release of cars in 2022 will be delayed to make way for the humanoid robot development of the company.

Toyota is now testing another, much older solution involving hydrogen: burning the stuff directly in an internal-combustion engine.

The automaker last week unveiled a race car whose inline-3 engine is designed to run on pure hydrogen. The race car is still being tested but will enter a round of the 2021 Super Taikyu Series race series in Japan this May.
