As one of the most expensive parts of electric vehicle, the performance and supply of power battery affect the development of electric vehicle.At the same time, mastering battery production and improving battery technology will also help to control the cost of electric vehicles.

It is not a new thing when automobile manufacturers enter the battery field. For example, Mercedes Benz owns or is building nine battery factories in Europe, Asia and North America; the battery factory jointly established by Volkswagen and northvolt, a Swedish battery company, is expected to be put into operation in 2024; and auto companies such as BAIC, SAIC, Changan and Geely have also established their own battery factories.

Today, Tesla has also announced its official entry into the battery field.

As a matter of fact, Tesla has long wanted to produce its own batteries.

Tesla acquired Canadian battery manufacturing equipment and engineering technology company Hibar, and company Maxwell. specializing in battery and capacitance in 2019Both companies are developing technologies to achieve better battery quality and more efficient production costs.

In battery manufacturing, Tesla also has a good technical reserve.

Compared with the current 2170 battery,Tesla said the energy increased five times and the power capacity increased six times. When applied to Tesla, it can increase the mileage by 16% and reduce the cost per kilowatt hour by 14%.

In the future, Musk hopes to build a factory on every continent to improve business scale and efficiency, reduce delivery cycles, and improve the liquidity of funds.

At present, the construction of Tesla Shanghai plant phase II has started. Meanwhile, the construction of Tesla's factories in Berlin, Germany and Texas has also started.
