Briefly describe the major breakthrough in LR6 battery technology

　　At present, even Mercedes-Benz has to admit that fuel vehicles have no future, and electric solutions are the mainstream trend. However, in addition to battery life issues, what is currently troubling manufacturers and users is energy attenuation. Generally, the power storage performance of the battery will decrease as the number of charges and discharges increases, which brings about a more serious problem of insufficient battery life.

　　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 Canada's Dalhousie University said in the latest technical speech that the research team has made major breakthroughs in the field of battery performance, allowing the vehicle to control the battery degradation within 480,000 kilometers after driving 480,000 kilometers. Within 5%.

　　Jeff Dahn said that improving certain chemical components in NMC ternary lithium batteries can limit the harmful gases produced when the battery operates under high pressure, and this improved battery cell can still have excellent performance after more than 1,200 cycles. Performance.

　　If the battery cells are made into a battery pack, 1,200 cycles is equivalent to a vehicle driving about 300,000 miles (approximately 480,000 kilometers). This means that based on driving 20,000 kilometers per year, Tesla owners will have to use the battery after 24 consecutive years of driving. The capacity can still reach 95% of the factory capacity.

　　Currently, this technology has been used in Tesla’s upcoming new car, which is expected to be the Model 3 sedan scheduled to be launched in July this year.
