According to foreign media reports, Tesla CEO Elon Musk said that he hopes to extend the service life of car power batteries to 1.6 million kilometers, and Tesla’s latest new patent submission is very likely to Accelerating this goal, this patent uses a new battery lithium process that not only improves battery quality but also saves costs.
When it comes to Tesla batteries, we usually think of Panasonic. For a long time, Panasonic batteries were Tesla’s exclusive supplier. After the Shanghai factory was put into production, it also cooperated with LG Chem , CATL reached a cooperation. This makes many people believe that Tesla is inferior to BYD because the latter has its own battery technology, and some people have even complained about Tesla's shortcomings for a long time. But cars are very complex industrial products, and purchasing core components from other countries is nothing new. For example, BMW’s power batteries are also purchased from my country’s CATL.
This time Elon Musk publicly stated that he is applying for new battery technologies, which I believe will surprise many people. In fact, Tesla has already launched a layout in the field of power batteries, and has successively acquired Maxwell Technologies and Hibar Systems, which led to the news of applying for battery patents.
It is reported that Tesla’s patent will limit the formation of impurities during the heating process of battery material production by correcting the ratio of lithium and other metals, helping to extend the service life of the battery. This seemingly simple sentence actually affects the process. And the production requirements are still very high.
The service life of 1.6 million kilometers is also a very remarkable achievement, and the number of charges and discharges can reach more than 4,000 times. The current ternary lithium battery can be charged and discharged about 1,000 times, and the lithium iron phosphate battery is about 2,000 times. Tesla's new battery will undoubtedly have more advantages. However, if this new battery is installed on a Tesla model, it does not mean that it can drive 1.6 million kilometers, because the service life of the car depends on many factors, including the quality of the vehicle's parts, manufacturing and assembly processes. Cars have been around for more than 100 years, and there are very few that have a mileage of more than 1 million kilometers.
