Hier sind interessante, neue Details zu einem Batteriepatent, das Tesla letzte Woche eingereicht hat. Noch interessanter ist der Tweet von Elon Musk dazu!
“Current cells use a jelly-roll design in which the cathode, anode, and separators are rolled together and have a cathode tab and an anode tab to connect to the positive and negative terminals of the cell can. The path of the current necessarily travels through these tabs to connectors on the outside of the battery cell. However, ohmic resistance is increased with distance when current must travel all the way along the cathode or anode to the tab and out of the cell. Furthermore, because the tabs are additional components, they increase costs and present manufacturing challenges.”
Way more important than it sounds
