Researchers have uncovered a previously unknown problem with lithium-ion batteries. With a simple trick, they managed to increase the lifespan to 19 times.
An international team of researchers has uncovered a previously unknown problem of commercial lithium-ion batteries. Your solution: a new battery technology. A change in the so-called “unloading window” could keep batteries up to 19 times longer. The basis is one study On the micrococesses on the cathode surface – where the decisive chemical reactions take place.
Specifically, it is about a hidden mechanism that leads to a loss of oxygen on the surface if the unloading is too deep. The result: The structure of the cathode changes from a stable layer to a poor conductive “rock cold phase”.
This hinders the lithium-ion flow and accelerates the aging of the battery. Nickel -rich cathode materials are particularly affected, such as those used in modern high -performance batteries. The researchers were able to show how this problem can be avoided.
Lithium-ion batteries: Lifespan reduced too deeply
So far, such damage only occurs at very high charging tensions. However, the researchers have now been able to prove that a gradual renovation process is used when unloading below 3.0 volts. This triggers a so-called quasi-conversion reaction. Oxygen is withdrawn, by -products and an insulating layer form that disturbs the current flow. In addition, gases and fixed residues are created that affect the interior of the cell.
The analysis of various discharge tensions revealed a clear connection: the deeper the discharge (up to 2.0 volts), the faster the capacity collapsed. In the event of a discharge closure above 3.25 volts, however, the cathode structure remained largely intact. As a result, the cells stood significantly more charging cycles and only had a hardly noticeable loss of performance.
A little trick with a big impact
According to researchers, this improvement can be implemented without new materials or expensive additives. It is sufficient to program the software of batteries or devices so that they do not unload unnecessarily deeply. For electric cars, smartphones or inpatient storage solutions, this is a simple way to significantly increase the lifespan.
The study shows that many today’s batteries simply age faster than necessary due to unfavorable discharge strategies. With the new understanding of the reactions on the surface, future batteries could be more robust, more efficient and durable – without additional costs.

As a Tech Industry expert, I am very excited about the breakthrough in extending the lifespan of lithium batteries by 19 times. This is a significant advancement that could have a major impact on the tech industry, as lithium batteries are used in a wide range of devices, from smartphones to electric vehicles.
Extending the lifespan of lithium batteries could lead to longer-lasting devices, reduced waste, and potentially lower costs for consumers. This could also help to address some of the environmental concerns associated with the disposal of lithium batteries.
I am eager to see how this research develops and how it could potentially revolutionize the way we use and think about lithium batteries in the future. This kind of innovation is what drives the tech industry forward and I look forward to seeing the practical applications of this breakthrough.
