12 EVs underwent 1,250,000-mile test to see which batteries degraded the least and there was a clear winner

These 12 electric cars were made to drive 1,250,000 miles to test which of their EV batteries degraded the least, and one battery type emerged as a clear winner.

This experiment was conducted by Morgan Stanley Research and involved 12 electric vehicle models and 100 sample batteries across four Chinese cities.

It’s a common concern among EV drivers to contemplate how much their battery will degrade over longer distances.

But if the results of this test are anything to go by, there’s one battery type that is clearly superior.

Which EV batteries degraded the least?

There was a runaway winner in this experiment.

Anonymous models 11 and 12 both use CATL batteries, and these cars retained the most range after 1.25 million miles – 250 miles of range, to be exact.

By way of comparison, cars with rival batteries only retained around 218 miles or less of range in the test, and degraded more quickly.

This isn’t the first time that CATL batteries have come out on top – one wind-solar storage project found that the company’s cells lasted 14 years with more than 90 percent capacity retained.

CATL – short for Contemporary Amperex Technology Co., Limited – is the world’s leading manufacturer of EV batteries.

Its work has featured in cars from Tesla, BMW, Volkswagen, Ford, Hyundai, and Honda.

To say that the company is a giant in the world of EVs is something of an understatement.

CATL is constantly breaking new ground

Whilst the company is Chinese in origin, its reach is truly global.

Not only is it powering EVs around the world, but it’s also producing EV batteries right in the heart of Spain with 2,000 workers toiling away in its gigafactory.

But the company isn’t satisfied with just powering the EV world – it wants to revolutionize it.

A few months back, the company unveiled a sodium-ion battery.

This battery is called Naxtra and has completed its final wave of fire regulation checks.

The excitement is heightened as experts claim that the new sodium-ion EV battery will last around 3,600,000 miles, and can be recycled for household usage if you move on from your car.

Given that battery packs can be swapped out in three minutes at stations throughout China, there’s hope these long-lasting power banks could be available worldwide in years to come.

All of this is further proof that China’s car technology is miles ahead of the US.

Chinese companies like CATL and BYD dominate battery production – representing between 70 and 90 percent of the global lithium-ion battery value chain.

Now that’s what you call domination.
