CATL ready to produce batteries planned for 16 years and 2 million KM

Finally a tangible innovation, even for an additional cost of 10% the business seems good to me:

It's good, it's better, but you don't get out of lithium. Alas.

But few technical details, what is technology to start ?? It's more specific here: transports-electriques/nouvelles-batteries-nmc-811-a-grande-duree-de-vie-perte-3-pour-200-000-km-t16490.html


The Chinese firm Contemporary Amperex Technology Ltd (CATL), the world's largest manufacturer of lithium-ion batteries, has developed a new power supply unit capable of traveling two million kilometers, which equates to an average lifespan of 16 years old. A boon for car manufacturers, who see here a way to boost sales of their electric vehicles.

Among the supplier's customers: Tesla, Volkswagen, BMW and Toyota. Note that current batteries are generally designed (and guaranteed) for approximately 240 kilometers, or eight years. Extending the life of these power supplies is therefore a real turning point in the electric car sector; such a battery could survive the original vehicle in which it was installed, and then be reused in a second vehicle.

Increased demand for electric vehicles predicted for 2021

The announcement is “timely” in a very specific economic context. The electric vehicle sector has, like many others, suffered the full brunt of the consequences of the pandemic and containment measures: the fall in oil prices has made the fuel-car sector much more competitive ... Not to mention that the uncertainty about the loss of resistance of batteries and their potential for replacement remains one of the main obstacles limiting consumers' enthusiasm for electric cars.

But if the crisis will cause sales to drop throughout the year, CATL CEO Zeng Yuqun estimates that demand for electric vehicles will increase from the start of 2021: "Car buyers who hold back during the pandemic create a pent-up demand that will be triggered from next year, and directed to high-end models, "he said. According to Bloomberg New Energy Finance (BNEF), sales of battery vehicles are expected to increase by 8,1% next year in China - which accounts for the largest share of global sales of electric vehicles. The increase should be around 5% in Europe.

Last year, the Tesla company announced that it would have to put into production a battery capable of operating over a million miles, and General Motors Co. recently said it was approaching that milestone. The distance is still equivalent to circling the planet 50 times! To anticipate needs, CATL has therefore invested heavily in R&D, in order to design even more efficient batteries. This new battery with an exceptional lifespan is still based on lithium-ion technology, but includes a few changes that CATL has not communicated.

As of yet, no sales contract has been officially released, but Yuqun says his company is ready to produce its new battery. All that remains for manufacturers is to place an order! Note that according to the Chinese leader, these batteries will be around 10% more expensive than current batteries.

A real endurance race…

Last month, Tesla announced its imminent presentation of a new battery "a million miles", a durable and low-cost battery, capable of significantly lowering the price of electric cars. Elon Musk also announced the creation of a battery day to present all of Tesla's innovations in this area. But the event originally planned for May has been postponed.

Tesla's new batteries have the particularity of having a low cobalt content and contain additives and materials which reduce certain internal stresses and thus store more energy, longer. The company is also planning a high-speed, largely automated manufacturing process - within "terafactories" - to reduce labor costs. According to Reuters, this long-life battery designed by Tesla was developed in collaboration with CATL.

It should be noted that the two firms had already signed a two-year agreement at the start of the year, providing that CATL cobalt-free lithium iron phosphate batteries should be installed in the Model 3 sedans produced in the gigantic new Tesla plant near Shanghai. These batteries are the specialty of CATL: they are based on a technology developed in-house, called Cell-to-Pack, allowing to store a maximum of energy in the same space, while ensuring that the battery remains light.

CATL, which has a production unit in Germany, is also expected to supply more than 70% of the batteries required by BMW. The Chinese giant also works with Audi and Porsche. Zeng has not ruled out building a factory in the United States, although he said the company has no specific plans yet. According to the CEO of CATL, the electric car industry will mark a turning point towards 2030-2035, at which time it should overtake the fuel vehicle industry. Predictions considered a bit optimistic by BNEF experts, who predict this changeover a few years later.
