Tesla could launch a million mile battery this year


Tesla is expected to launch a million-kilometer battery this year or early 2021 for its Model 3 in China, as part of a larger plan to introduce low-cost, more durable batteries that would bring a vehicle Electric (EV) prices at par with conventional gasoline cars, Reuters reported Thursday, citing sources close to the automaker’s plans.

A million-kilometer battery is just one of the cornerstones of Elon Musk’s strategy to make Tesla an energy company, the sources said.

Last year, a team from Dalhousie University in Halifax, Canada, who is researching for Tesla, said in an article that it had tested the chemistry of lithium-ion battery cells supposed to be capable of power electric vehicles (EVs) for more than 1 million miles and last at least two decades in grid energy storage.

Jeff Dahn and his research team presented the results of the tests of “the excellent chemistry of lithium-ion pocket cells with moderate energy density” which should be able to power an electric vehicle on more than 1.6 million kilometers (1 million miles) and last at least two decades in grid energy storage.

Researchers at Dalhousie University have an exclusive agreement with Tesla, and they indicated that they had designed battery cells with higher energy density without using the solid state electrolyte that many believe to be a necessary condition for increased density.

After a first deployment in China for the Model 3, the million-kilometer battery will be further improved in terms of cost, storage capacity and energy density and will be used in other Tesla models in markets outside of China, including North America, according to Reuters sources. , while Tesla declined to comment on the report.

Earlier this year, Reuters announced that Tesla is in talks with Chinese company Contemporary Amperex Technology Co Ltd (CATL) to make batteries without using cobalt for its vehicles made in China. Cobalt, one of the most expensive metals for batteries, is one of the main reasons why electric vehicles are even more expensive than vehicles with internal combustion engines.
