Researchers conduct electrochemical performance testing on lithium-rich layered oxide cathode materials at the Ningbo ...

The anode (positive electrode) is made from impure copper and the cathode (negative electrode) is made from pure copper. Pure copper forms on the cathode. The slideshow shows how this works.

QuantumScape thinks it solved the biggest problems with its anode-free lithium metal battery that will most likely debut on a Volkswagen EV ...
