When we talk about Tesla's batteries, we usually think of Panasonic. For a long time, Panasonic was the exclusive supplier of Tesla batteries. After the Shanghai factory was put into production, we reached a cooperation with LG Chemical and Contemporary Ampere Technology Co., Ltd.. This makes many people think that Tesla is not as good as BYD, because the latter has its own battery technology, and some people even spit out Tesla's slot. However, automobiles are very complex industrial products, and it is nothing new to purchase core components from abroad. For example, BMW's power battery is also purchased from Contemporary Ampere Technology Co., Ltd. in China.
This time, elon musk's public statement about applying for new technology in batteries will surprise many people. In fact, Tesla has long been in the field of power batteries, and has successively acquired Maxwell? Technology and Hibar? Systems now has the news of applying for a battery patent.
It is reported that by modifying the ratio of lithium to other metals, Tesla patent will limit the formation of impurities in the heating process of battery materials and help the battery to extend its service life. In a seemingly simple sentence, the requirements for technology and production are still very high.
The service life of 1.6 thousand kilometers is also a very remarkable achievement, and the number of charge and discharge can reach more than 4000 times. At present, the charge and discharge times of ternary lithium battery are about 1000, and that of lithium iron phosphate battery is about 2000. Tesla's new battery will undoubtedly have an advantage. However, this does not mean that this new battery can travel 654.38+0.6 million kilometers when installed on Tesla models, because the service life of a car depends on many factors, including the quality of parts, the manufacturing and assembly technology of the whole vehicle. Cars have been born for more than 100 years, and the mileage exceeds 100 kilometers rarely.
