Historical data from Tesla’s current battery packs show about 5% capacity degradation after 50,000 miles (80,000 km) and the capacity levels off for about 150,000 more miles before hitting 90% capacity.

Those are already pretty good results, but Tesla aims to do better with Jeff Dahn, a renowned battery researcher and the leader of Tesla’s research partnership through his battery-research group at Dalhousie University.

The scientist and his team recently unveiled their latest research on a new chemistry that could enable even more cycles without significant degradation. expand full story
