Reports that Tesla Model 3 battery cobalt content is 75% lower than Volkswagen battery


According to a report from the German business newspaper Wirtschaftswoche, the cobalt content of the Tesla Model 3 battery is 75% lower than that of the current Volkswagen battery, which highlights the transformation of traditional cars into electric vehicles. The long way to go.
Frank Blome, head of the Center of Excellence for Battery Cells, pointed out in the business newspaper that the battery of Volkswagen ID3 (formerly known as ID Neo) contains 12-14%. cobalt. In contrast, as of last year, Tesla successfully reduced the cobalt content of the Model 3 battery to 2.8%. Since then, Tesla has continued to study its batteries. This means that in Tesla’s new electric car’s battery, the cobalt content is lower.
Cobalt is one of the most controversial ingredients in electric vehicle batteries, in part because some cobalt mines have very harsh working conditions. This problem has caught the attention of senior car manufacturers such as BMW. BMW recently announced that it will stop buying any cobalt from the Republic of the Congo. The Republic of the Congo has some of the most notorious cobalt mines in the world, as these cobalt mines use a lot of child labor. The Volkswagen Group has issued a set of strict guidelines to suppliers, promising to use only cobalt from the source “innocent”.
Although the gap between the cobalt content of the Tesla Model 3 battery and the cobalt content of the Volkswagen battery is still large, Blom points out that the German car manufacturer is still working to improve its battery and added that he The company’s next-generation automotive battery is expected to have half the cobalt content of existing batteries.
“The prototype battery we are developing now has a lower cobalt content than previous batteries. Some of our previous tests have shown that our quality is still up to standard,” he said.
Tesla’s proficiency in electric vehicle batteries is one of the company’s most powerful advantages in the market. For more than a decade, Tesla has been working on battery research and development. In fact, it has been ahead of the competition for several years.
A study by consulting firm Benchmark Mineral Intelligence concluded last year that Tesla was able to reduce the cobalt consumption per vehicle by an average of 59% from the early Model S to Model 3.
Tesla CEO Elon Musk pointed out that Tesla’s goal is to make its batteries use almost no cobalt. The company explained this in an updated letter in the first quarter of 2018 and highlighted the high energy density of the Model 3 battery.
“In all of the batteries used in electric vehicles, the energy density of the battery in Model 3 is the highest. We have significantly reduced the cobalt content of each battery pack while increasing the nickel content and maintaining excellent thermal stability. With this goal in mind, the cobalt content of our nickel-cobalt-aluminum cathodes has been lower than the cobalt content of the next-generation cathodes produced by other battery manufacturers at 8:1:1 nickel-manganese-cobalt,” Tesla wrote.
