Million-Mile Battery to Revolutionize Electric Vehicles

More efficient, longer-lasting batteries are needed to ensure the future of the electric vehicle market. Thanks to Jeff R. Dahn and his Dalhousie University research team, a “million-mile battery” may soon be a reality. Dahn is Tesla’s battery research partner. In “A Wide Range of Testing Results on an Excellent Lithium-Ion Cell Chemistry to be used as Benchmarks for New Battery Technologies,” Dahn describes a new Li-ion battery cell with a single crystal NMC cathode and an advanced electrolyte. The new battery should power an electric vehicle for one million miles and last at least 20 years in grid energy storage—making Tesla’s electric-powered semi-autonomous driving cars and trucks viable.

Jeff Dahn and his lab, who are doing battery research for Tesla, have released test results for an impressive new battery cell that is going to be Tesla’s new million-mile battery, according to a source familiar with the matter.

The new battery tested is a Li-Ion battery cell with a next-generation “single crystal” NMC cathode and a new advanced electrolyte.

Dahn’s team have been extensively testing these cells and based on the results, they think that the battery could power an electric car “for over 1.6 million kilometers [1 million miles].”
