Lithium batteries can be brought back to life and made infinite: the problem lies in the compound that needs to be injected into them.

The discovery of a method to revitalize and indefinitely extend the lifespan of lithium batteries represents a major advance in the energy field. However, the challenge lies in the compound required for this transformation, raising environmental and technical questions.

A way has been found to resurrect lithium batteries and make them infinite. The issue is the compound that needs to be injected. The battery field has surprised us more than once lately, such as the emergence of a chemical element we had never seen on Earth, which multiplies the capacity of batteries by ten.

These objects have been part of human life for over 100 years. They have been used in all areas, from simple scientific calculators to electric vehicles, including robots and satellites.

Over time and with the improvement of technologies, new models have appeared to enhance their performance. Today, lithium batteries are the most used due to their efficiency, even though they can still be improved.

Revived and Infinite Lithium Batteries

A group of Japanese researchers has developed a method that allows lithium-ion batteries that have degraded over time to be recharged and eventually regain a capacity close to what they had when they were new.

The process involves injecting chemicals into the battery to increase its lifespan. A method that could be key to solving the long-anticipated collapse of battery production in the face of the growing demand for electric vehicles.

Although we are “surrounded” by this type of batteries, they still have some details to improve, such as their short lifespan and autonomy. These are gradually reduced.

However, this group of researchers from Toyota found the solution: injecting positively charged lithium ions and negatively charged electrons into the system to reverse this type of degradation. This injection allows extending the lifespan of batteries, but also makes the recycling process easier and less expensive. This discovery, published in the journal Joule, represents a breakthrough in the industry.

How do Infinite Lithium Batteries Work?

The researchers first tested different chemical substances capable of generating the recovery reaction. After several trials, it turned out to be lithium naphthalenide, capable of stimulating charged particles and restoring 80% of the original capacity of the piece.

Their technique has demonstrated the battery’s effectiveness in different sizes. The researchers also found that its effect was maintained over time. Laboratory tests showed that the injection allowed the battery to retain its new capacity for 100 charge and discharge cycles.

“The system’s effectiveness has been verified not only with small-sized batteries used in the laboratory but also with large-sized batteries intended for automotive use,” explains Nobuhiro Ogihara, from Toyota’s Central R&D Laboratories, Inc. in Japan, to New Scientist.

The New Lithium Batteries Do Not Work in All Cases

Despite its effectiveness, the researchers acknowledge that this system does not work in all cases. It cannot bring back to life parts damaged by structural deficiencies. Moreover, they warn that to achieve more significant capacity recovery effects, it would be necessary to wait longer for the composition of the reactants and their concentrations.

In conclusion, Toyota’s experts know how to bring lithium batteries back to life. But to do so, they must inject lithium naphthalenide, which poses a problem because it is a compound that pollutes during extraction and processing. While waiting for a more sustainable solution to be found or for a new solution to appear, another option has emerged on the market: batteries that operate solely on air.
