Tesla Will Launch A New Battery Product With A Life Of 1.6 Million Kilometers In 2020

- Sep 17, 2019-

According to foreign media reports, a few days ago, Jeff Dahn and his team who developed batteries for Tesla announced a new battery core that can reach 1 million miles (about 1.6 million kilometers).

The team revealed that the cell uses a new generation of single-crystal NMC materials and a more advanced new electrolyte.

Tesla's battery research and development team has done a lot of testing on this battery, including long-term charge and discharge cycle test, storage test at 20 ° C, 40 ° C, 55 ° C and other temperatures, and high in 40 ° C environment. Accuracy power analysis, etc.

The results show that the cell can be maintained for 4000 cycles at a high temperature of 40 °C. If in Tesla's liquid cooling system, the cell cycle can exceed 6,000 times. This means that the battery life can reach 1 million miles (about 1.6 million kilometers).

In addition, the team also said that this battery can also be used in the power grid for at least 20 years.

Tesla CEO Elon Musk has said that all the design, testing and verification of electric vehicles should be aimed at achieving the goal of “1 million miles”. At present, Tesla batteries obviously do not meet the above requirements. The report of Sla self-built battery factory, the date of its own battery, may not be far.
