According to foreign media reports, CEO Elon hopes to extend the battery life of electric vehicles to 1.6 million kilometers. Tesla's latest patent, which describes a new lithium-ion process that not only improves battery performance, but also saves costs, is expected to accelerate this goal. The traditional production process sometimes leads to the formation of impurities in the lithium substrate, while reducing the lithium content in the battery can reduce the impurity pollution, but also lead to poor electrochemical performance of the battery. In response, Tesla submitted a patent entitled "synthesis method of nickel cobalt aluminum electrode", which revised the ratio of lithium to other metals, and will limit the formation of impurities in the heating process of battery material production. This process is helpful for the development of impurity free single crystal Ni co al, and the new electrode combination enables the battery to reach more than 4000 charging cycles. In its patent, Tesla said that the reduction of pollutants will help extend the overall service life of the battery and help Tesla take a big step forward in the production of 1.6 million km batteries for its cars. With the development of Tesla battery technology, the service life of its electric vehicles can reach 20 to 30 years, even longer than that of ordinary gasoline powered vehicles. In addition to submitting battery patents, Tesla has been busy acquiring battery companies, including Maxwell technologies and HIBAR systems. Both companies are developing technologies that enable better battery quality and more efficient production costs.
