Tesla, which revolutionized the electric car, said on Tuesday that it wanted to cut the price of batteries in half through a combination of improvements at various stages of their production.

“How many years can we accelerate the adoption of sustainable energy? This is the real measure of success,” said Elon Musk.

Faced with climate change, "we must act," he said, expressing confidence in the group's ability to offer an electric car at $ 25,000 within three years, a reduction of at least $ 10,000 compared to to the basic model that it offers for sale.

But to achieve this, we must lower the cost of batteries, said the boss of the group. 

To do this, Tesla, in a fairly technical presentation, exposed several advances at various stages of battery design: on the design of cells, on the production line, on the use of silicone, on the manufacturing of the cathode and the metals used, and on the integration into the car itself.

All this should ultimately make it possible to reduce the production cost of a kilowatt hour by 56%.

The event, broadcast live on the internet, began with a little quack: no sound on the video presenting the company's activities.

Covid-19 requires, he stood outside, the speakers succeeding on a podium in front of the shareholders who had been able to make the trip, installed at the wheel of a little more than 200 cars of the brand neatly arranged in a large parking lot .

A few blasts of the horns regularly greeted Mr. Musk's announcements.
