Although solid-state batteries have been identified as the “terminator” of liquid lithium-ion batteries, there is always one person who does not think so.
He is Elon Musk.
Contrary to the eagerness of major automobile companies towards solid-state batteries, Elon Musk and his Tesla have always kept quiet and distance from this new technology.
At the Tesla Annual General Meeting of Shareholders and the “Battery Day” event held in 2020, Elon Musk announced that the company’s newly developed “4680” battery has a 5 times increase in energy density, a 16% increase in cruising range, and 6 times in charge and discharge power. , The cost per kilowatt-hour has dropped by 14%, and the speed of the battery production line has increased by 7 times.
The new battery pack adopts a module-free design and is composed of approximately 960 (40×24) “4680” batteries. Compared with a battery pack composed of more than 4,400 “2170” batteries, the volume and weight are greatly reduced, and the energy density is increased to 300Wh/kg , Easily break through the energy density limit of liquid lithium-ion batteries.
Elon Musk is not tech savvy on battery ?
No, it is precisely because he is a battery technology genius that he “sees through” the “futures” tricks that are constantly being performed between car companies and solid-state batteries.
It is an indisputable fact that solid-state batteries surpass liquid lithium-ion batteries in all aspects, but it is not difficult to find the commonality of solid-state batteries from the timetables of major auto companies: commercialization has taken too long, and 2030 is the most optimistic estimate.
Here, let us turn our attention to the Bollore Group, the only French Bollore Group that has achieved mass production in the field of power batteries so far.
The Bollore Group is one of the institutions with the longest history and strongest R&D capabilities in the solid-state battery field.
In October 2011, the Bolloré Group began to equip its self-developed electric vehicles “Bluecar” and electric buses “Bluebus” with solid-state batteries manufactured by BatScap. These vehicles are used in shared services in Paris and the suburbs of France. As of the closure in 2019, 2,900 solid-state battery electric vehicles have served nearly 200,000 users, and used approximately 18,000 times a day.
Bolloré Group is the first company to successfully commercialize solid-state batteries on a large scale, but the capacity of this solid-state battery pack is only 30 kwh, and the energy density is only 100Wh/kg, which is only half of that of liquid lithium-ion batteries.
