However, Tesla engineers seem to have found a better solution.
Tesla’s chief battery scientist Kurt Kelty and technology research and development partner Jeff Dahn of Dalhousie University in Canada stated in their latest technical presentation that the research team has made a major breakthrough in the field of battery performance. Within 5%.
Jeff Dahn said that improving a certain chemical composition in the NMC ternary lithium-ion battery can limit the harmful gases that appear when the battery is running under high pressure, and this improved battery cell can still have excellent performance after more than 1200 cycles. Performance.
The battery cells are made into a battery pack. 1200 cycles are equivalent to about 300,000 miles (approximately 480,000 kilometers) of the vehicle. This means that the Tesla owner will continue to drive the battery after 24 years of driving at 20,000 kilometers per year. The capacity can still reach 95% of the factory capacity.
At present, this technology has been used in Tesla's upcoming new cars, which is expected to be the Model3 sedan scheduled to be launched in July this year.
