At present, even Mercedes-Benz has to admit that there is no future for fuel vehicles, and the electric scheme is the mainstream trend. However, in addition to battery life issues, manufacturers and users are now suffering from energy degradation. Generally, the storage performance of the battery decreases as the number of charge and discharge times increases, which brings about a more serious problem of insufficient battery life. However, Tesla's engineers seem to have found a better solution. JeffDahn said that improving the chemical composition of the NMC ternary lithium battery can limit the harmful gases generated during high-voltage operation of the battery, and the improved battery cell can still have excellent performance after more than 1200 cycles. which performed. Making a battery cell into a battery pack, 1200 cycles is equivalent to driving a vehicle for about 300,000 miles (about 480,000 kilometers), which means that after four years of continuous driving, Tesla owners calculate the battery after 24 consecutive years. The capacity can still reach 95% of the factory capacity. The technology is currently being used in Tesla's upcoming new car, which is expected to be the Model3 sedan scheduled for launch in July this year.

Tesla battery breakthrough: 480,000 km only attenuated 5%
Recently, Tesla's chief battery scientist Kurt Kelty and technology research partner Jeff Dahn of Dalhousie University in Canada said in the latest technical speech that the research team has made a major breakthrough in battery performance, enabling the vehicle to attenuate after driving 480,000 kilometers. Control is within 5%.
