When electric cars are discussed, almost the entire debate revolves around range, charging points, and price. However, there is a key aspect that rarely makes headlines but is fundamental to the model's sustainability: battery recycling at the end of their useful life.
And it's no small matter. The battery is, by far, the most expensive and strategic component of an electric vehicle. Its proper management as it ages is crucial from both an environmental and economic perspective.
Batteries don't just stop working suddenly. With use and the passage of time, they gradually lose capacity. When this capacity drops below 80%, the car continues to function, but with reduced range, longer charging times, and less predictable performance.
At that point, many users choose to replace the battery. And that's where the real challenge begins: what to do with hundreds of kilograms of batteries filled with valuable materials.
While in Europe and the United States electric cars are still perceived as the "future," in China they are clearly the present. They have been selling electric cars on a large scale for almost ten years, which means that many batteries are already reaching the end of their useful life.
This has forced the country to confront a problem we will all face before anyone else: the mass recycling of lithium batteries. And as is often the case, those who address the problems first, find the solutions first.
Battery recycling is not a simple task. There are two main approaches:
1. Giving them a second life
Many cells still function correctly, although they are no longer ideal for a car. These batteries can be reused in:
. Energy storage systems
. Backup batteries
. etc.
It is an efficient and relatively inexpensive solution, but not an unlimited one.
2. Material Recovery
When a battery reaches the end of its useful life, it is disassembled to recover critical materials such as lithium, cobalt, nickel, manganese, etc.
This process requires advanced technology, significant investment, and high safety standards, but it is key to reducing dependence on imported raw materials.
China already faces this problem, and they have not only identified it but are also addressing it on an industrial scale. The government offers incentives for battery replacement and recycling, and large companies have created their own recovery networks.
A clear example is CATL, the world's largest battery manufacturer. According to public data, it has:
. More than 200 collection centers
. Capacity to process nearly 300,000 tons of used batteries
. Mineral recovery rates close to 99%
Other Chinese companies are following the same path. The result is clear: they learn faster, optimize faster, and reduce costs sooner.
This is a key point that is often overlooked: the advantage of being at the front of the line. By leading the electric vehicle market, China is facing the challenges of the sector's maturity sooner. But that's not a disadvantage; it's quite the opposite.
When other countries begin to accumulate millions of aging batteries, China will already have:
. Installed infrastructure
. Optimized processes
. Real-world experience
. Reduced costs
This accumulated advantage will translate into cheaper, more sustainable, and increasingly competitive cars.
Meanwhile, in Europe, we continue to debate whether by 2035 we will have to sell only electric cars or also fossil fuel vehicles. In the United States, with increasingly hostile rhetoric toward electric vehicles, the delay could be even greater.
The outcome is predictable: by the time the market truly matures, others will have already paved the way. As the saying goes, there's none so blind as those who will not see.
The future is coming sooner than we think, and in just a few years we'll see more Chinese electric cars on our roads, at increasingly unbeatable prices.
Meanwhile, the European automotive industry is under pressure, closing plants and cutting jobs.
Battery recycling isn't a problem for tomorrow. It's a test of industrial maturity, and China is passing it faster than anyone else.
