Chinese company announces lithium-ion battery with a lifespan of 16 years!

Specialized in the manufacture of lithium-ion batteries, the Chinese giant CATL says it is ready to manufacture a new battery. Intended for the electric automobile market, this battery would have a lifespan of 16 years, equivalent to two million kilometers! Nevertheless, there is a certain vagueness in this matter linked to Tesla, a privileged partner of CATL.

A resounding announcement

Contemporary Amperex Technology Limited (CATL) produces lithium-ion batteries for electric vehicles and energy storage systems. Partner of Tesla but also other manufacturers such as BMW, Toyota or Volkswagen, this company was the subject of an interview published in Bloomberg June 8, 2020.

In this article, CATL CEO Zeng Yuqun made a resounding announcement. Indeed, it is a question of the production of a lithium-ion battery whose lifespan is incredible, namely 16 years old, or about two million kilometers. He said his company was ready to produce this battery if ordered.

It should nevertheless be noted the total absence of technical details concerning this new battery, in particular concerning its capacities and its autonomy. However, Bloomberg says the Tesla Model 3, currently in production in China, may be the first vehicle to benefit from the new battery. On the other hand, it remains a some vagueness around this case.

Two long-lasting batteries rather than one?

The point is that Tesla is looking to individually develop battery technology in order to limit its dependence on its suppliers and reduce costs. In a statement made in 2019, Elon Musk mentioned a partnership with Dalhousie University (Canada) for the development of a battery with a 1.6 million km lifespan. However, the interested party had also mentioned the Tesla Model 3 of Chinese manufacture as the first vehicle to be equipped, before its marketing in 2021.

However, Tesla is also working with CATL on different types of batteries. The objective is to reduce their cobalt content, or even to completely eliminate the presence of this metal.

In contrast, the statement by the CEO of CALT clearly announces that the new battery in question here would not be exclusive to Tesla. So, this makes everyone a little confused since it would be a question of two long-lasting batteries from these two partners. This possibility is still difficult to consider. The Tesla Battery Day, scheduled for this month of June 2020, should clarify things on this subject.
